Cavity Wall Insulation

Step by Step

Installing insulationHaving cavity wall insulation installed couldn´t be easier!

It´s a simple process and is normally completed within 3 to 4 hours, without damage or mess to your house or garden.

Assessment

Before the installation, we will undertake a free no obligation suitability assessment of your property to confirm that it is suitable for insulation. Click here to apply for yours.

During the assessment your assessor will also check if any additional ventilation is required. Where additional ventilation is considered necessary this will typically involve the fitting of one or more plastic 9" x 6" air vents and the assessor will advise where the vent(s) will be fitted during the installation stage.

Installation

The installer will need access to all walls, so will need to get inside attached garages, lean to sheds, conservatories etc. The insulation can only be really effective if all walls are done, so if you have a wall right on the boundary, you will need to liaise with your neighbour as the installer will need to go onto their property.

The cavity wall insulation is normally applied from the outside through small holes approximately the size of a 50 pence piece, which are drilled approximately 1.5 metres apart all across the external walls.

The insulation material is then injected through the holes, filling the cavity. The holes are then filled in to make as perfect a match as possible with the existing wall.

The drilling process does create some vibration - so it is recommended to remove any pictures or ornaments from the internal side of your external walls, for their safety and your peace of mind.

The drilling process inevitably creates a little dust, but this will be cleared by the installer at the completion of the job.

Depending on the type of heating appliances in your home it may be necessary to install a permanent ventilator if none already exist to ensure there is adequate ventilation, usually where there is a working solid fuel appliance and in some types of gas and oil fires. Of course your assessor will inform you of this at the assessment stage.

Up to 12 weeks following completion of the works you will receive a Cavity Insulation Guarantee Agency (CIGA) 25 year guarantee. Please keep this with the paperwork for your home as it should be passed onto the next occupier should you move in the future.
