Cavity Wall Insulation

Insulating cavity walls can be achieved by injecting insulation material into the cavity from the exterior. This process involves drilling holes in the outside walls, injecting insulation through the holes, and then sealing them.

While cavity wall insulation has previously received negative feedback, we at Purple Carbon assure our clients of the quality of our work. We encourage you to read our customer testimonials to gain insight into the work we have completed.

It is worth noting that historically, cavity wall insulation did not have to adhere to strict regulations. However, at Purple Carbon, we ensure that all our work is up to code and completed with diligence. Our installation process involves drilling small holes, approximately 22mm in size, at intervals of around 1m in the exterior wall of your home. Our team then uses specialized equipment to blow insulation into the cavity. Once the insulation is in place, we fill the holes in the brickwork, leaving them barely noticeable.

Cavity Wall Insulation is done quite quickly in a house and causes limited mess, it is normally completed in a day. This is absolutely FREE as long as you qualify. Why not head over to our contact us section to check your eligibility and book your self in for a free survey.
