Cavity Wall Insulation


Cavity Wall Insulation is quick and easy to install.

A series of small holes are drilled into the mortar joints
on the external brickwork. Glass wool is then blown into the
holes until an effective heat seal is formed within the cavity.

The majority of work is carried out on the outside of your
home with minimal inconvenience to you.

We can insulate homes with different cavity specifications such as hard to treat/narrow cavity and partial fill.

A simple survey will establish if cavity wall insulation is
suitable for your home.

On completion, your home will be more energy efficient,
more comfortable, and easier to keep warm.

A 25 year Cavity Insulation Guarantee Agency (CIGA)
warranty is given on all cavity wall insulation work.
CIGA is an independent body set up by the Government.
The guarantee covers any defect in materials or workmanship
in connection with the installation, which will be rectified without charge. The guarantee remains valid for all subsequent owners of the property.
