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

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.

As I was more afraid of causing damp problems in our dry, well ventilated loft than I was of having an inadequately insulated loft, I had got a few quotes for loft insulation over the last 15 years, but had never taken it further than getting quotes, because I never quite trusted any of the companies quoting for the work. This year, I decided to look into it yet again and got a few more quotes. RJ Insulation was the most expensive of the quotes, but for the first time, I felt I had found a company that could reassure me over my fears that thicker insulation was not always a good thing. Everyone I dealt with was professional and polite. The team that did the work were efficient and extremely hardworking. I was informed of any issues on the day of the installation as soon as they occurred, all issues were dealt with to my satisfaction, and when I questioned whether the area that had been boarded was as big as I had expected (I had requested the same area of the loft floor to be covered as previously, but it seemed that the measurements made had been only for the area in the middle, up to the struts, plus some loft storage trays), they returned after the weekend to add more boarding for me at no extra cost. As the work has only just been completed, I can't comment on the effectiveness of the insulation, but I can confirm I am delighted with the lovely clean space and storage up there - it is a far more pleasant and secure environment than was previously the case.

I cannot express how really outstanding R&J Ipswich was with our loft installation! From the moment I spoke to Alfie to the time the installation team left it was a pleasure to deal with them. Alfie put me at ease with their credentials and validation from a variety of organisations. John came and carried out a survey the day after I first spoke to Alfie. John is a knowledgeable person who outlined the process clearly and answered all our questions thoroughly. He was back to us promptly with the installation date. The team arrived. Ramon, Max and Linas were here at 7.30 for a prompt start. They were courteous and friendly throughout and did an amazing job. The house was cared for and the cleaning at the end of the first day and on completion was perfect. Lindsay from the accounts department too was prompt and business -like in her work. Don't go elsewhere!

I am so happy to have chosen R J Insulation to carry out our loft work. Alfie was amazing at communicating with me, explaining everything, ensuring I was understanding the product and process. Excellent customer service. The job was completed in 2 days as planned and the team was very pleasant, knowledgeable, polite and left everything clean and tidy. All in all a fantastic experience and highly recommended.
