Different Types of Sustainable Loft Insulation

Loft Insulation Installer offer a wide range of different eco-friendly loft insulation materials, including recycled plastic, sheep wool, and foil. But what is actually used as loft insulation? Most materials used for loft insulation are mechanically woven into wool-like patterns and flattened into rolls of thick padding, though you may be astounded by the variety of ‘origin stories’ these materials can have. Insulation fibre can be taken from organic sources such as sheep wool, recycled plastic… or even aluminium foil!

Recycled Plastic Loft Insulation (SupaSoft)

Each pack made out of thousands of disused plastic bottles, SupaSoft is a leading brand of recycled plastic loft insulation. Easy to install, safe to handle and silky to the touch, SupaSoft is a reliable, environmentally-friendly alternative to traditional loft insulation material.

Sheeps Wool Loft Insulation (Thermafleece)

Ever wonder how warm sheep must be for them to be able to easily withstand freezing temperatures? With organic, sustainable sheep wool loft insulation, you can experience the amazing heat-retentive and toxin-repellent effects that nature can provide in the comfort of your own home.

foil Loft Insulation (SuperFOIL)

A truly innovative, modernised method of insulation first tested in NASA spacecraft, SuperFOIL is a form of aluminium multifoil loft insulation that can smartly reflect heat back down from the loft ceiling and circulate it back throughout the rest of the house.

  • It’s safer – Installation of insulation can be messy, uncomfortable and dangerous work due to the sharp, easily inhaled particles that shed from allergenic materials such as fibreglass, which may already be installed in your home and need replacing.
  • Less risky – We enforce the use of proper equipment to ensure everyone’s safety, such as goggles and face masks, to prevent particle inhalation and other injuries.
  • It’s tidier – Our loft insulation fitters are able to thoroughly survey your property to assess any potential hazards before the work begins, and will even tidy up any mess after the work is done for good measure.

Our Loft Insulation Process

Discover more about the steps we’ll take in the loft insulation process. Our simple, hassle-free process is designed to take you smoothly from initial enquiry to installing your loft insulation.

01

Free Survey

Before beginning the installation work, our professional surveyors will review your property to get a feel for the building’s dimensions and whether it is suitable for loft insulation. This is a great opportunity for us to create a brief project overview, assessing the ventilation, lighting, potential hazards, stability of the loft floorboards, and more.

02

Quote

Not long after the full survey is conducted and all your requirements are discussed, we will issue you a detailed quote, which will include a total cost breakdown and take into account the full scale of the work, so should be no worries about being left in the dark!

03

Place Your Order

Once you have an ideal date locked down, waste no time in booking with us! With only a 25% deposit required, you can easily secure all the information you need to proceed, namely the contract, schedule of payment and a thorough overview of all the installers’ plans for the work ahead, with estimated dates of completion included.

04

Technical Survey

To ensure that no space on the loft floor is left uncovered, all stored objects should be removed before the assessment begins, if possible. Fitting loft insulation can be time-consuming work, particularly when older fibreglass or stone wool pads are to be placed or removed, especially if you want to still use your loft as a storage or living space.

05

Installation

When that’s done, the installers will come to lay down the insulation material. Our professionals are trained to use the correct safety equipment and precautions for all kinds of installation procedures, without taking any perilous shortcuts. For a standard-sized three-bedroom house, a full loft insulation installation should only take around 2-3 hours to complete.

Signs of Inadequate Loft Insulation

There are several telltale signs of poor loft insulation that you can keep an eye out for.

thermal imaging camera for house insulation
  • Draughts – During chilly weather, noticeable draughts coming from above or the loft ceiling feeling cold to the touch are sure signs that the heat retention is compromised.
  • Differing temperatures – If upstairs rooms of the house have noticeably different temperatures to downstairs – the upstairs rooms being much chillier than anywhere else in the house is definitely a bad sign.
  • Rising heating bills – Rising heating bills can also be a cause for concern, as you may be wasting more energy than needed to keep your house warm.
  • Traces of vermin – Traces of vermin like rodents and insects in your loft may be an indicator that they have broken through parts of the insulation material.
  • Infrared scan – If you can observe no particular symptoms but still feel that your loft insulation isn’t working properly, you can have an infrared scan performed during a survey to confirm the amount of heat it is losing.

    Debbie McCluskey

    Loft Insulation Installers were on time for the appointment and insulated my loft with 300mm of insulation with funding as promised and no charge to me. They were clean and tidy and completed the job at the time specified. I would happily recommend this loft insulation company!

    Nigel Hinds

    Loft Insulation Installer cleared out my loft of all its contents, hoovered it clean, and installed new wool insulation, eaves ventilators and boarding. The team also helped return my items for storage to the loft afterwards. The company was pleasant and straightforward to deal with throughout the process, thorough and trustworthy. The work was carried out tidily, and the house was left clean and neat. The work took less time than I had previously been advised. There was slight damage to a bedroom ceiling, and an appropriate resolution was swiftly agreed. Now I need to find out if it will keep the house warmer – I hope so.

    Graham

    Such an easy company to deal with. From start to finish the communication was excellent. No lengthy waiting, a thorough survey, such that suitable materials and approach were taken. The installation team were fantastic – so polite, courteous, hard-working, knowledgable, respectful of us and our home and knowledgable. The area was left as clean as when they arrived. Nothing was too much trouble, despite some awkward and tight areas. The level of workmanship is really second to none and we are looking forward to reaping the benefits of what is now a properly insulated home. whether you have a relatively modern home or one that’s as quirky as ours (60’s style) I would not hesitate to recommend RJ Insulation as a credible provider.

    K Clarke

    We needed two loft spaces re-insulated, so put out a request on Bark. RJ Insulation contacted us immediately and, after we looked at their website and checked their reviews, we arranged for their engineer to visit and provide a quotation. We were kept well-informed by email of exactly what, when and how all would happen. The insulation team arrived on time, were most professional, worked hard, did a brilliant job and cleaned up after themselves. They used lambs wool in the smaller loft and Superfoil in the larger loft – both look spectacular and our house is warmer already. An excellent company.

    Noor

    From the initial contact with the company to the complete job done went very smoothly. The quotation, survey and installation of the insulation were done by very courteous, friendly people. They arrived on time on the day the storm Eunice was causing travelling very difficult and we were not expecting them to show up at all. They removed and bagged all the old insulation and installed the new insulation. I am also very pleased with loft boarding but there was some misunderstanding about the fitting and I was not happy about it. I contacted the office about this and I was assured that the fitters will return and finish the job to my satisfaction. I am very pleased that the promise was kept and all the work is done to a very high standard and we are very happy with the warm house. We will definitely recommend Loft Insulation Installer to everyone who wishes to have their loft installation done.

    Jo Worman

    From the initial enquiry through to the end of the job was just fantastic. I had an immediate quote from the surveyor and everything was explained thoroughly. The job was to empty a rubbish tip that was the loft, including mattresses and water tanks and 40-year-old cladding, hoover the whole area, install the Superfoil to the rafters and lay new sheep wool and new boarding, a two-day job. I was quickly given date and had several calls from the office to ensure me that everything was going to plan. This is once-in-a-lifetime customer service and professionalism. The quality of the work is stunning. It’s incredible. I cannot say enough about this company, they really do deserve all the recognition and appreciation they get. Of all the work I have done in many years in many countries, this was the best experience. Super job, super team, super quality.
    I wish them all the best.

    Anthony Davis

    Just had our attic boarded and insulated by the rj team.Very good experience, they could not have been more informative and helpful.We would definitely recommend them to friends and family.

    Eco-Friendly Loft Insulation Installation FAQs

    How much loft insulation do I need?

    Our professional surveyors will estimate exactly how much loft insulation will be suitable for your property based on the materials used, the size of the loft space, and other factors. As a general rule, it is highly recommended that at least 250mm of overall material is used. Please take a look at the ‘How thick should loft insulation be in the UK’ page for more detailed information on government guidelines.

    Which type of loft insulation do I need?

    Different properties may have different needs when it comes to loft insulation. For example, older properties may be best suited for sheep wool insulation since they often have untreated timbers that cannot contain water very well and are therefore prone to degradation. Sheep wool's hygroscopic qualities allow it to absorb water vapour easily.

    If you get a survey conducted with us, we can provide our best recommendations for the kind of material that would be most suitable for your loft. Always feel free to get in touch and ask for some advice!

    How much does loft insulation cost?

    The cost for a full installation service can vary dramatically. To get an estimated price, feel free to get in touch with a member of our team, who may be able to give their opinion based on your property’s specifications and other variables such as type of material you require, the thickness, the brand, etc. which can all affect the pricing.

    How thick should loft insulation be in the UK?

    Government regulations dictate that loft insulation should have a U-value of no more than 0.16W/m2K. A U-value is calculated by adding up all of the R-values (the measurement of how heat a material is capable of insulating) of all materials involved in an insulation installation and dividing by 1 to determine how much heat is lost.

    Different materials produce different R-values and U-values, so differing amounts of them may have to be used to fully insulate a loft. It is broadly accepted that, for most applicable loft insulation material, somewhere in the range of 250-300mm is the ideal thickness. For properties with inadequate insulation thickness, it is required that the layering is topped up with additional material. Different kinds of materials can be mixed together to achieve this.

    Can you have too much loft insulation?

    Yes, over-insulated lofts can be detrimental. Just as insulation is designed to trap heat inside a house, it can also prevent moisture in the air from escaping. Too much insulation can cause dampness to build up in certain areas, such as around pipes, window sills and kitchen ceilings. This build up of moisture can in turn lead to mould, which can be very detrimental to your respiratory health if it is left unchecked.

    Ideally, your house should have an even balance of insulation and ventilation, both to allow cold air to escape and to keep enough warm air inside. Correctly surveying and measuring a property should ensure that the right amount of insulation is used, and fitted in the appropriate places. Expert insulation installers like our team can

    What is the purpose of loft insulation?

    As with all aspects of home insulation, the main goal of loft insulation is to keep as much warmth in your household as possible, while also maintaining a healthy air flow throughout the property. Poorly insulated interior walls can cause a huge drain of heat in your home, especially during the cold Winter months. Just as shocking is the potential money loss it can inflict – up to £200 worth of energy bills can be wasted on excess heating.

    With effective, modern insulation materials, any heat rising throughout your house can be properly blockaded by the roof, then circulated back down to the living areas. However, excessively cold, damp or draughty attics can definitely exacerbate any problems with heat retention. Whether you need a simple upgrade or a full replacement to your loft insulation, we are here to help with whatever installation services you may require.

    What is loft insulation?

    Loft insulation is material that is used to insulate the attic or loft space of a building. It is typically installed between the joists in the attic or loft, and helps to keep the building warm in the winter and cool in the summer by reducing heat loss or gain through the roof. This can help to lower energy bills and make the building more comfortable and energy efficient.

    There are several types of loft insulation available, including foil, sheep wool, and recycled plastic. Each type has its own benefits and drawbacks, and the best choice will depend on the specific needs and requirements of the building. Loft insulation is typically installed by professionals, who will follow the manufacturer's instructions and use specialized tools and equipment to ensure that it is installed correctly. The amount of loft insulation required will depend on the size and type of the building, as well as the local climate and energy efficiency goals.

    The exact amount of insulation needed will depend on factors such as the type of insulation being used, the size and orientation of the roof, and the climate in which the building is located.

    It is also important to consider the type of heating and cooling system being used, as well as the age and condition of the building. For example, a building with an older heating and cooling system may require more insulation to achieve the same level of energy efficiency as a newer system.

    If you are unsure about how much loft insulation you need, it is a good idea to consult with a professional or refer to local building codes for guidance.

    How is loft insulation installed?

    Loft insulation is typically installed by professionals, who will follow the manufacturer's instructions and use specialized tools and equipment to ensure that it is installed correctly. The process of installing loft insulation typically involves the following steps:
    1 - Preparation: The attic or loft space should be cleaned and any debris or obstructions should be removed. It is also a good idea to check the condition of the roof and make any necessary repairs before installing the insulation.
    2 - Measurement: The dimensions of the attic or loft space should be measured in order to determine how much insulation is needed. The insulation should be cut to size as needed.
    3 - Installation: The insulation is typically laid between the joists in the attic or loft space, and may be secured with pins or staples to keep it in place. It is important to ensure that the insulation is evenly distributed and that there are no gaps or voids.
    4 - Sealing: Any gaps or openings in the attic or loft space, such as around light fixtures or vents, should be sealed with appropriate materials to prevent air leakage.

    The process of installing loft insulation can vary depending on the size and complexity of the project, as well as any challenges or issues that arise. It is important to follow the manufacturer's instructions and to use caution when working in the attic or loft space to avoid accidents or injuries.

    How long does loft insulation installation take?

    The length of the loft insulation installation process will depend on the size and complexity of the project, as well as any challenges or issues that arise. A small attic or loft space may be insulated in a few hours, while a larger space may take a full day or more.

    The process of installing loft insulation typically involves preparing the attic or loft space, measuring and cutting the insulation to size, installing the insulation, and sealing any gaps or openings. Each of these steps can take some time, especially if the space is large or if there are obstacles or challenges to overcome.

    It is important to allow sufficient time for the installation process, as rushing the work could result in a subpar installation that does not provide the desired level of energy efficiency or comfort. It is also a good idea to plan for contingencies in case there are delays or unforeseen issues.

    How much does loft insulation installation cost in the UK?

    The cost of loft insulation installation in the UK can vary depending on the size and type of the building, as well as the cost of the insulation material and labour. In general, the cost of loft insulation installation can range from a few hundred pounds for a small attic or loft space to several thousand pounds for a large space.

    The type of insulation being used, the size and orientation of the roof, and the climate in which the building is located can all affect the cost of the project. Fiberglass insulation is generally the least expensive option, while sustainable insulation such as foil, sheep wool and recycled plastic insulation may be more expensive. The cost of labour can also vary depending on the location and the experience of the contractor.

    It is a good idea to shop around and get quotes from multiple contractors to find the best deal on loft insulation installation in the UK. It is also important to consider the overall value of the project, including the potential energy savings and other benefits when deciding on a budget.

    What is the Best Type of Sustainable Loft Insulation to Use?

    When it comes to insulation, there are many factors to consider, including sustainability, cost, and effectiveness. Here is a comparison of three sustainable insulation options: foil, sheep wool, and recycled plastic.
    - Foil insulation: Foil insulation is made from a layer of reflective material, typically aluminum, that is laminated to a backing material. It works by reflecting heat back into the building, which helps to reduce heat loss and increase energy efficiency. Foil insulation is a sustainable option, as it can be recycled and does not contain any harmful chemicals or VOCs (volatile organic compounds). However, it is generally less effective than other types of insulation and may not provide as much long-term energy savings.
    - Sheep wool insulation: Sheep wool insulation is made from the wool of sheep and is a natural, sustainable insulation option. It is renewable, biodegradable, and recyclable, and it does not contain any harmful chemicals or VOCs. Sheep wool insulation is also effective at trapping air and reducing heat transfer, making it a good choice for insulating buildings. However, it may be more expensive than some other insulation options.
    - Recycled plastic insulation: Recycled plastic insulation is made from recycled plastic materials and is a sustainable alternative to traditional insulation materials. It is durable, moisture-resistant, and does not contain any harmful chemicals or VOCs. Recycled plastic insulation is also effective at trapping air and reducing heat transfer, making it a good choice for insulating buildings. However, it may not be as effective at reducing noise as other insulation materials.

    Ultimately, the best type of sustainable loft insulation will depend on your specific needs and budget. Consider factors such as the effectiveness of the insulation, the sustainability of the materials, and the cost when choosing the best insulation for your project.

    It's also important to consider the R-value of the insulation, which is a measure of its effectiveness at reducing heat transfer. Higher R-values indicate greater insulation effectiveness. Most experts recommend installing loft insulation with an R-value of at least R-30 to R-49 in the attic or loft of a building.

    In conclusion, there are many sustainable insulation options available, and the best choice will depend on your specific needs and budget. Foil, sheep wool, and recycled plastic insulation are all sustainable options that can help to reduce heat loss and increase energy efficiency, but it's important to consider the effectiveness and cost of each option before making a decision.

    - Foil insulation: Foil insulation is made from a layer of reflective material, typically aluminum, that is laminated to a backing material. It works by reflecting heat back into the building, which helps to reduce heat loss and increase energy efficiency. Foil insulation is generally less effective than other types of insulation, and it may not provide as much long-term energy savings. However, it is a relatively cheap option and can still help to reduce energy bills to some extent.
    - Sheep wool insulation: Sheep wool insulation is made from the wool of sheep and is a natural, sustainable insulation option. It is effective at trapping air and reducing heat transfer, making it a good choice for insulating buildings. Sheep wool insulation can help to significantly reduce energy bills and save money over the long term. However, it may be more expensive than some other insulation options upfront.
    - Recycled plastic insulation: Recycled plastic insulation is made from recycled plastic materials and is a sustainable alternative to traditional insulation materials. It is durable, moisture-resistant, and does not contain any harmful chemicals or VOCs. Recycled plastic insulation is effective at trapping air and reducing heat transfer, making it a good choice for insulating buildings. It can help to significantly reduce energy bills and save money over the long term.

    Overall, the amount of energy and money you can save with loft insulation will depend on a variety of factors, including the R-value of the insulation, the effectiveness of the insulation at reducing heat transfer, and the local climate. Most experts recommend installing loft insulation with an R-value of at least R-30 to R-49 in the attic or loft of a building to achieve the greatest energy savings.

    Is loft insulation worth the investment?

    Loft insulation can be a worthwhile investment, as it can help to reduce energy bills and increase the energy efficiency of a building. By trapping air within the insulation material, loft insulation slows down heat transfer and helps to keep the building warm in the winter and cool in the summer. This can result in significant energy savings over the long term.

    Yes, it is generally possible to add loft insulation to an existing property using foil, sheep wool, and recycled plastic insulation materials. These materials can be installed in the attic or loft of an existing property to increase energy efficiency and reduce energy bills.

    How does loft insulation work

    How does loft insulation work?

    • The diagram shows the inner workings of the processes of insulation; convection, conduction and radiation.
    • Convection – Convection is a key law of thermodynamics – it describes how cold and hot air particles interact with each other in closed spaces. When outnumbered, cold air particles become excited by the introduction of warm air particles, while in contrast, hot air particles are decelerated and cooled by exposure to a larger amount of cold air.
    • Conduction – As you can see, a pad of insulation should be porous like a sponge, with the interior air pockets acting as a barricade preventing hot air from conducting through from one side to the other. However, as the hot air particles collide with each other, they continue to excite themselves, thereby producing more heat.
    • Radiation – Heat can also travel in the form of mostly harmless infrared radiation, which struggles to pierce solid matter. Upon coming into contact with an insulated surface, most radiated heat will simply be reflected back.

    Loft Insulation Installation Energy bill savings

    By installing loft insulation and in turn improving the thermal efficiency of your home, you can save you a significant amount of money on your fuel bills. A quarter of heat is lost through the roof, so an effective layer of protection in the loft can quickly reduce the overall amount of energy wasted.

    The savings can vary depending on the type of house you live in – some households will be able to save up to £580 on their energy bills every year. We have made a graph to show the approximate savings that can be made through good insulation depending on the type of property you own.

    Carbon dioxide savings loft insulation

    Loft Insulation Installation Carbon dioxide savings

    Good loft insulation helps to reduce a home’s carbon footprint and therefore combat climate change. The reduced heat loss emanating from your home will mean that you will not have to leave the heating systems running for so long. Not only will heat be retained for longer, the improved air circulation will allow your home to stay cooler during the hottest days of summer.

    For an example of how this all works in practice, a detached home could expect to save 1300kg of carbon dioxide each year. That’s the equivalent of charging a smartphone over 150,000 times.
