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

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.

From the first contact with RJ Insulation we have felt in safe and knowledgeable hands. The preliminary consultative stage by phone was very helpful for us to understand our options, and subsequent follow ups addressed our questions clearly. The installation of our wool insulation product has just been completed by Max and colleagues. They were efficient, careful and thorough in fulfilling the brief, and dealt successfully with some very tricky corners of our loft space. Overall we are very pleased with the product and service we have received from RJ Insulation, and have high hopes of being a lot warmer next winter.

Contacted RJ Insulation through the website. Alfie got back to me and walked me through all the options with no pressure to buy (gave me some time to think it over and called back the next day). Decided to arrange a survey for the following week. John carried out the survey. He was on time, very thorough and respectful of my property. Got a callback from Alfie moments after John left and was pleased to hear the price had gone down based on the survey, so decided to go ahead with the installation. Installation was a breeze despite a complex loft space - this was made possible by a great team of installers lead by Ramon. They arrived on time (on both days) and quickly got to work. They kept me informed as to what they were doing at all times (e.g. when installing downlighting covers, shower mixers, etc...) and brought me up to show me their progress after cleaning the space and installing the new layers of insulation. Everyone involved was absolutely brilliant. Can't recommend RJ Insulation highly enough!

Myself and the wife had been looking to get our loft converted. On speaking to a few firms we decided to go with R J insulation. We got a call from Alfie who took time in telling us about what was available . We decided to go with the second option after a day of thinking it over. The guys who arrived came at the stated time all were very polite and called me sir ( i had to tell them to call me raymond) the work that these guys done was excellent. Max explained everything to us and took time to do so . The guys were here from 08:00 until 19:00 . We are well pleased with the work done and have been telling people we know about the company. I have always said you get what you paid for and we certainly got that. Work was finished to a very high standard . We don’t have a small lift and it must have been challenging. Max and his guys did a great job . The guys hoovered on the last day and left the place tidy . We can’t thank the guys enough and we will be using our loft for storage area now .
