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

Great company to work with, from soup to nuts: . Quotation process . Scheduling our work . Promptness and efficiency . Tidiness and cleaning up . Courtesy and engagement . Post-work customer assurance. What we don't yet know is: does it sufficiently insulate our attic bathroom? Winter time will tell!

I recently had loft insulation installed by R&J Limited, and I couldn’t be more impressed with their service from start to finish. From the initial consultation to the final completion, the team was professional, efficient, and incredibly knowledgeable. The crew arrived on time, worked seamlessly, and made sure to leave the space spotless once the job was done. Not only did they do an excellent job insulating the loft, but I’ve already noticed a significant improvement in the warmth and comfort of my home. I highly recommend R&J Limited to anyone needing insulation work done. Their expertise, attention to detail, and customer-focused approach made the experience stress-free and pleasant. I’ll definitely be reaching out for any future home improvement needs!

Very good customer service throughout and Alfie worked with us to find a time to do the survey and the works. Good explanation of why sheep's wool insulation would be better for our property and what the work would entail. Works were completed quickly by two very friendly workmen. They cleaned up extremely well afterwards and left our house in a better state than when they started. I'm very happy to recommend R J insulation

We had SuperFoil installed in our loft. We were most impressed with the speed and efficiency of both the office staff and the installation team. The work was completed within two weeks of the original booking and the installation team arrived on time (actually a little early!) and managed to complete the work in under five hours. It remains to be seen how effective the SuperFoil proves to be - we are hoping that, next summer, we have a much cooler top floor. We live in a three-storey town house with a mansard roof which, up to now, has trapped the heat in the middle of summer.

When first speaking with Alfie I felt that the level of service, detail and communication was almost too good to be true - this is the best compliment I can offer everyone at RJ Insulation. The pre-inspection and RAMS report was also run to a high professional standard, arranged quickly with everything explained to me. Lastly, Max and Lunas were brilliant when undertaking the actual work in the loft space. RJ Insulation set a bar for what a professional business should be and how to conduct themselves with integrity while generating value. I would be very happy to recommend them.

Max, Linus and Ramon arrived exactly on time, and lost no time in protecting the carpet and then carrying out the required work in the loft. They explained exactly what was happening and invited us to inspect the work as it progressed. They were friendly and informative and we were very impressed with the standard of their work. Highly recommend.

They arrived right on time given, did the work in half the time, were polite, a credit to the company. They hoovered up after themselves, took away all the rubbish, showed photos of the work. Couldn’t wish for better service, 10/10!

What wonderful workmen to have in my home. From the initial visit by Lee to discuss options to the actual fitting by Ramon and Linas everything went smoothly and uneventfully. The work took a day and a half. Dust sheets covered the carpets and before leaving each day the hall, stairs and landing were hoovered.
