Thermal insulation is a crucial aspect of enhancing a home's energy efficiency and reducing heating bills.

Internal wall insulation involves adding insulation to the interior face of external walls to improve the property’s thermal performance. While it offers numerous benefits, careful consideration and proper installation are essential to avoid potential issues.

There are several methods for installing thermal insulation, with the most common approach being the construction of a new stud wall. This allows for the addition of insulation within the wall structure. However, it’s important to note that this may not always be the most effective solution for every situation, and alternative methods should be evaluated based on the specific requirements of the home.

It’s crucial to assess whether internal wall insulation is the best insulation solution for your home, as it can be a disruptive process. Installation often requires the removal and re-fixing of items such as switches, radiators, and kitchen units. Therefore, careful planning and consideration of the potential impacts on the home’s aesthetics and functionality are necessary.

Proper attention should be given to challenging areas like reveals (the sides of window and door openings) and floor voids. These areas require special care to ensure a seamless and effective barrier against air leakage. By addressing these points of potential air infiltration, internal wall insulation can significantly improve the thermal performance of the home.

Additionally, it’s important to consider the moisture management aspect of thermal insulation. The insulation layer should be combined with proper vapour control measures to prevent the build-up of moisture within the wall structure. This helps maintain a healthy indoor environment and prevents potential issues such as condensation and mould growth.

It is advisable to consult with professionals experienced in thermal insulation and building science when considering internal wall insulation. We can assess your home’s specific characteristics, such as its construction type and existing insulation, and provide expert advice on the most suitable insulation method and materials.

Adam visited our property to advise on noise from a pool plant room that was coming into the house. He advised on the best approach to eliminate the vibration that was being heard. On his advice this has now been resolved. Adam was great to deal with and we would highly recommend his company
Katja K.
The customer service was fantastic with our quotes updated several times to match our requirements. The team that came out were very efficient and stayed late to finish the job in one day without being asked to. The sound proofing is of really high quality and we haven't heard any noises at all from our neighbours since it was installed
Peter D.
I can't praise City Insulation enough they are very professional, informative, courteous and they certainly know their stuff. They completed our lounge and dining room soundproofing in two days, which was completed with great care and respect to our home and furnishings (thanks to a great installation team). Do yourself a favour and choose City Insulation, it's no surprise that they get regular 5 star ratings.
