The Benefits Of Cavity Wall Insulation

The Superglass Multi-Roll roll out loft insulation provided by Loftfoam Ltd offers a comprehensive range of benefits, making it an excellent choice for both residential and commercial insulation needs. Here are the key advantages:

Cavity wall insulation serves as a barrier against heat transfer, effectively reducing the need for excessive heating and cooling systems. By creating an insulated layer within your walls, this solution prevents heat loss during colder months and minimizes heat gain in the summer. As a result, homeowners can significantly lower their energy bills and enjoy year-round comfort without relying heavily on heating or air conditioning.

Experience a more consistent and comfortable indoor temperature throughout the year with cavity wall insulation. Gone are the days of dealing with chilly drafts or uneven heating. By maintaining a stable environment indoors, cavity wall insulation ensures that you and your family stay cozy and comfortable, regardless of the season.

Cavity wall insulation isn’t just beneficial for homeowners—it’s also great for the environment. By reducing energy consumption and decreasing reliance on fossil fuels for heating and cooling, cavity wall insulation helps to lower carbon emissions and combat climate change. Choosing this sustainable solution contributes to a greener future for generations to come.

Investing in cavity wall insulation can significantly increase the market appeal and value of your home. Potential buyers are increasingly attracted to properties that offer energy-efficient features and long-term cost savings. With cavity wall insulation, you can boost your home’s resale value while enjoying the benefits of lower energy bills and improved comfort.

One of the most appealing aspects of cavity wall insulation is its quick return on investment. With energy savings and potential government incentives available, homeowners can recoup their initial investment in a relatively short timeframe. Enjoy the benefits of lower energy bills and increased comfort while knowing that you’re making a smart investment in your home’s future.

Customer Testimonials

The MD, Peter, came to provide the quotation. During several conversations, he was able to help with additional suggestions that allowed us to undertake other work ahead of the re-insulation, meaning that no further disturbance would be required. Sam and Josh were prompt, polite and extremely professional. The work was carried out to a high standard and I was impressed with how quickly everything was completed. The leak in the loft that Sam identified was dealt with quickly by another supplier and the whole work was complete by 4pm the same day!


The boss contacted me on the same day as I put a request into checkatrade for someone to insulate my loft. He arranged a visit a couple of days later to measure up and quote a price. He was professional, knowledgeable and reassuring that no job was too small. I had a very reasonable quote before he left and the job was booked in for the following week. The fitter arrived on time, he knew exactly what the job entailed and started work immediately. He kept me informed as he was going along of how he was insulating the loft.Superb job completed by an excellent company with professional staff


The company gave an order of magnitude estimate before we agreed a visit. The visit was carried promptly and the detail of the work agreed. The quotation for the work arrived promptly and a prompt start date agreed. The tradesman carrying out the work arrived on time , verified the work needed and got on with the job. He was very pleasant to deal with. When the work was complete the operation of the ladder was clearly explained and demonstrated and I tested the ladder which met my expectations. All necessary paperwork (manufacturers instructions etc ) was provided.
