About

RJ Insulation specialise in ECO friendly, natural and sustainable loft insulation.

Pre 1920 homes.
One of our assessors holds a Level 3 award in giving advice on energy efficiency measures to listed and traditional buildings.

He recommends using the Sheepswool. Sheepswool is hygroscopic, therefore is specified for listed and traditional buildings.

1920 -1960s homes.
For 1920 - 1960s homes we use SuperFOIL Insulation. SuperFOIL is designed to keep you cool in the summer and warm in the winter. SuperFOIL states that it can increase the value of your home.

Post 1970.
For 1970s or later we offer the SupaSoft Insulation. Supasoft is made entirely out of single use recycled plastic bottles. on average it takes 10,000 - 15,000 Single use recylced plastic bottles out of landfill and into your loft. It never degrades and is approximately 11% more thermally efficient than the typical Fibreglass.

We give out a lifetime guarantee for SuperFOIL, Sheepswool and Supasoft

Replacement Loft insulation

From first contact to finishing the job this company were the epitome of professionalism. They were prompt to answer my query and the ensuing visit to assess the job took place within days. I have a 5 bedroom house built 25 years ago and had the minimum of fibre glass loft insulation which had deteriorated. I was given a comprehensive look at alternative solutions and in the end plumped for Supersoft insulation because of its green credentials and insulating properties. The company sent a team of 3 to remove the old fibreglass, clean the loft and install the Supersoft. The team were absolutely excellent. Courteous, careful and exacting in their job. I cannot express how happy we are with the company, their team and communication by sales, installation and accounts during this work. The outcome is excellent. Thank you

Very professional job with a very good product
I have no hesitation in recommending RJ Insulation. I had old fibre-glass insulation replaced by Supasoft insulation. This was a professional job from start to finish. The installation itself was carried out by a team of three who arrived on time, were very hard-working and polite and kept everything clean. I'm very pleased with the end result. My loft was cleaned out after the old (very horrible) fibre-glass was removed and then the new insulation and venting put down. It now feels a clean and habitable environment! It is early days in terms of assessing the impact, but it does feel as though the house temperature is more evenly distributed as well as being warmer. The sales and administration service was efficient and personable and communications were clear and speedy. The job was assessed via a pre-installation visit and the work was completed to the agreed schedule and budget.

Max called me called me an hour and a half before his arrival to say when he would be there. He cut a very neat access to the loft space, removed some old insulation and laid Supasoft insulation. Everything was done very neatly and on completion the place was tidied up as though no one had been there. Max was very diligent and hard working. I would have no hesitation in using R J Insulation again and in recommending them to others.

I waited a year to post a review as I wanted to see how the supersoft insulation performed. We used less energy last winter. Was this the insulation or was it because energy prices were so high that I used the central heating less? This summer we have not had the high temperatures of 35C plus so again although the upstairs was much cooler at night than last year was this the insulation or was it just lower temperatures? So I think the house is a more even temperature and am pleased that we had it done. The team were punctual, polite and cleared everything away.

We have used RJ Insulation twice now, firstly on a 1950's semi, now on a 1930's semi. Both installations involved removing old fibreglass insulation, adding Supasoft, raised boarding of the floor, and lining the roof interior with foil. The first job also sealed an old square loft hatch, replacing it with a rectangular hatch and ladder combo. RJ Insulation have turned our unpleasant, dirty, and awkward-to-use lofts into clean, easily accessible storage areas. It's made such a difference to how effectively we can use the space: it feels like we have gained a lot. The team of installers have been very efficient and friendly throughout both 2-day jobs. They arrived promptly and left things clean and tidy at the end of each day. They may not be the cheapest you can find but, in our experience, the service offered by RJ Insulation is professional, thorough and ultimately worth paying for. The cost was clearly outlined upfront and they were able to accommodate us changing the installation date. We would recommend them to friends and family.

Recommend for sheep's wool insulation

We had our loft insulated with sheep's wool. We had enquired late last year but didn't get around to scheduling the work until this week. Someone came out to quote on Thursday and we agreed to a couple of weeks time, but someone had to postpone a similar installation and we were amazed to be able to swap dates and complete yesterday! Everyone we came into contact with was pleasant, thorough and knowledgeable. The work was completed with a minimum of disruption and in a straightforward fashion. The tidy-up afterwards was great! The process is not cheap, but worth the money for the peace of mind of a job well done. Would thoroughly recommend this company.

Our loft spaces have been transformed from draughty and dusty to warm, clean and eminently useful. A thoroughly efficient and professional operation from start to finish. A dedicated trio of industrious, polite and personable installers completed the work on time and to a very high standard. A thorough clean-up was carried out at the end of each day. My wife and I would highly recommend RJ Insulation. Our only regret is that we didn’t find these professionals sooner.

A large loft in our Listed house had a layer of Fibreglass and centuries of dust. The inspection was thorough and the work was completed in two days the following week. The Team who cleared the old fibreglass and installed the new Sheepswool were very helpful and efficient, leaving everything spotlessly clean. Very impressed but you have to pay for quality.
