Installing Thermafleece Sheep Wool Loft Insulation

Properties Best Suited to Sheeps Wool Loft Insulation

Sheep wool insulation is, of course, more than suitable for lofts in modern homes too! The wool’s moisture-absorbing properties make it excellently suited for timber framing as it can maintain the wood’s integrity for long periods of time.

Older Properties

Sheep wool insulation is widely considered to be ideal for older properties. On top of the safety, environmental and logistical advantages, owners of older houses need not stress about bug infestations. Despite many rumours and reports of early batches of sheep wool insulation being attractive to parasites, this is definitely no longer a cause for concern thanks to modern batches being sprayed with mild chemical repellents, harmless to humans.

Period Homes & Listed Properties

For very old, trust-protected buildings that may be more fragile and poorly ventilated than 20th-21st century houses, sheep wool is widely regarded as a superb option for loft renovation. The National Trust uses sheep wool insulation brands for many of their listed buildings, which range in scale from quaint thatched-roof huts to grand stately mansions.

Sheep Wool Insulation Benefits

In the often cold, damp climate of the UK, high-quality loft insulation can dramatically reduce your energy bills, carbon footprint, and overall discomfort! Not only that, installing effective insulation can increase the value of your property. If you currently live in a property that is poorly insulated, the improvements that can be made by good loft insulation will be immediately obvious. If you’re stuck for choice on which material to use, here are some of the many advantages to selecting Sheep Wool loft insulation:

Great value for money
For an affordable price, sheep wool insulates your home for ages without causing any long-term contamination risks.
Quality thermal insulation
Like the humble farmyard animal whose back it comes from, sheep wool can give you all the protection from the cold that you need!
Moisture absorbent
Sheep wool actually has potent hygroscopic characteristics which allow it to absorb airborne moisture without affecting the rate of insulation, so it can reduce humidity levels throughout your home.
Kind to the skin
Sheep wool does not cause itching or irritation, meaning that it can be directly handled without a metric tonne of safety equipment.
Fewer carbon emissions
As with all insulation types, installing sheep wool can reduce the amount of carbon dioxide escaping your home then polluting the atmosphere.
Organic
All sheep wool insulation is directly sourced from local British livestock, and the remarkable quality of the fabric once again proves that nature always knows best!
Sustainable and renewable
Sheep wool is a constantly regenerating resource that will never run out as long as sheep need shearing!
Efficient Installation
After the surveying and maintenance services are done, the installation process really is as quick and simple as slotting the insulation rolls between the loft rafters.
Purifies the air
Tying into its ability to absorb moisture, sheep wool can also improve your house’s air quality by soaking in minor toxins and pollutants that may be floating around in your home.
Strong acoustic insulation
Layered with thousands of tiny air pockets, sheep wool can act as an effective cushion for sound waves, reducing noise pollution throughout your home and neighbourhood.
Non-flammable
In the event of a house blaze, sheep wool will not catch fire thanks to its natural ability to char when exposed to flames.
Resistant to pests and mould
The wool will not attract damp, mould or vermin such as mice and moths thanks to some incidental chemical repellents.

Why Choose Professional sheep wool Loft Insulation Installers

  • Less stressful – For a guaranteed high-quality standard of work, a professional service like ours is always a safer bet compared to the likely stressful task of attempting to install insulation yourself.
  • High quality -With all of our experienced installers extensively trained and fully equipped, the risks of faulty fitting, personal injury or damage to your property are minimised when they are on the job.
  • 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 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.

  • 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.

    Michael Morton
    Loft Insulation Installer helped me to get a grant from the council for loft insulation. From the initial site review to installation, the team provided a professional and knowledgeable service, making the entire process a very straightforward one. My thanks to everyone involved.
    Secretary

    Dennis and Kade did a fantastic job in insulating our roof spaces. They treated our residents with the utmost respect at all times, as well as avoided 2 beehives along the way! True Professionals and a delight to work with.

    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

    Great service – kept informed throughout, from initial quote to fitting. The guys fitting the insulations were hardworking, courteous and cleaned up well after themselves. Would thoroughly recommend Loft Insulation Installer.

    Rosalind Ainscow

    Loft Insulation Installer service was excellent, efficient from initial enquiry/visit/survey to installation. Each member of staff we worked with were friendly and professional. Their advice was comprehensive, timely visit/inspection and their quotes were accurate when we checked them out. Each part of the job they let us know what they were doing and timeframe. The installation team arrived on time, worked diligently, and kept us informed throughout including videos and left the house spotlessly clean. We would highly recommend Loft Insulation Installer.

    Ellis

    The Loft Insulation Installers were great communicators throughout the entire process, from quote to on-the-day install. They keep you informed of what was happening and why, showing you the work-in-progess so you know what you’re getting. The install team were a really nice bunch, friendly, and helpful. The did a fantastic job, and finished up with immaculately clean house from the 3rd floor down to front door, where they’d transported all the materials. Thanks to all involved – very happy to recommend!

    John Tamblyn

    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.

    Sheep Wool Loft Insulation Installation FAQs

    What are the benefits of sheep wool loft insulation?

    There are many advantages to choosing sheep wool loft insulation. These benefits include but are not limited to:
    - Thick thermal insulation lined with thousands of air pockets.
    - Strong acoustic insulation.
    - Non-flammable.
    - Moisture absorbent.
    - Ability to absorb harmful substances in the air.
    - Resistant to mould.
    - Great longevity.
    - Organic, sustainable and renewable.

    Can you insulate a house with sheep wool?

    Yes, you can definitely insulate your home with sheep wool. It is thick enough to trap heat and sound easily, with superior performance in these areas compared to fibreglass or stone wool based on tests measuring R-value levels, which indicate the thermal resistance of a material.

    Is sheep’s wool insulation better than fibreglass?

    Sheep wool offers many advantages over fibreglass insulation. Chiefly, sheep wool is much easier and safer to handle than fibreglass, as it does not produce any harmful fragments that can irritate the human body. As such, sheep wool can be held bare-handed without any fear of injury. There is no need for mouth or eye protection while installing it, either.

    For comparison of the two materials in regard to the amount of heat insulated, studies of R-values indicate that sheep wool is thicker and therefore better at retaining heat than fibreglass.

    Lastly, sheep wool insulation is sustainable, naturally sourced and biodegradable, making it a more environmentally-friendly option compared to the more synthetic character of fibreglass.

    How thick should sheeps wool insulation be?

    The answer will depend on the age of your property. For older houses with pre-existing insulation, the minimum recommendation of thickness for a complementary layer of sheep wool loft insulation is 120mm to 160mm, or two layers of padding. However, lofts in newer houses without existing insulation will require at least 250mm to 270mm, or three layers, though this amount is recommended for older attics as well. One or two extra layers of insulation can rarely hurt, especially in colder climates.

    How often should you replace your loft insulation?

    Loft insulation can generally last up to 40 years - any material significantly older than that may likely need to be reviewed as damage accumulated from plumbing issues or simple wear-and-tear is expected. However, sheep wool is exceptionally good at absorbing moisture, meaning it is less likely to be severely damaged by small pipe or roof leakages than some other materials, though a quick inspection can never go amiss if you have concerns about larger leaks.

    Is sheep wool insulation sustainable?

    Sheep wool is sustainable and energy-efficient. It can stay in use for a long time, requires less energy to manufacture compared to other products, and can reduce the amount of wasted heating expenditure in your home. Sheep wool is a natural, renewable resource. After all, there are always some sheep out there needing to be sheared!

    Is sheep wool insulation flammable?

    No. You may be surprised to learn that sheep wool insulation is non-flammable. The wool will, at most, singe and smoulder slightly if burned or exposed to a major heat source, but the realistic possibility of bursting into flame is extremely low. To fully catch fire, sheep wool would have to be purposefully heated to insanely high temperatures, far hotter than anything a house blaze can produce.

    How does sheep wool loft insulation work?

    Thanks to its crimped structure, a single layer of sheep wool has thousands of tiny air pockets that allow it to retain heat. When applied to lofts, the wool forms a strong barrier of insulation for your home.

    How does sheep wool loft insulation work?

    • The diagram below shows the inner workings of sheep wool loft insulation.
    • Reduced mass – The millions of air pockets contribute to sheep wool having a low weight for its apparent size and thickness, as well as reducing the amount of heat loss via convection.
    • Humidity regulation – Water vapour that impacts the sheep wool insulation will be absorbed into its structure, reducing the overall humidity in the area. These same air pockets allow it to hold a huge amount of its weight in excess moisture.
    • Air purification – Similarly, tiny particles of dirt or other pollutants get harmlessly absorbed into the fabric, cleaning the air quality in your house.
    • Fire resistance – Once again, the crimped, air pocketed structure proves to be a lifesaver. If a flame hits a layer of sheep wool, the fire will scorch through the air bubbles without spreading away from the wool’s surface, before eventually charing out unceremoniously.
    How Sheep Wool Loft Insulation Works

    We don’t just install sheep wool insulation

    We offer a wide range of different 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, or plastic waste recycled for a better purpose… 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.
