CAVITY WALL INSULATION
If your home was built after 1920, the chances are that its external walls are made of two layers with a gap or cavity between them.
Uninsulated houses lose around a third of their heat through the wall and Cavity wall insulation literally fills that gap. Not only could it save you around £115 per year but it also lowers the carbon emissions and improves energy performance certificates rating.
Cavity Wall Materials.
Cavity Wall Insulation is made from granulate glass wool fibres, treated with inert water repellent and milled down in order to be blown into the cavity wall. The insulation will then be injected into the holes from the outside, via a machine in a van.
Average time for a 3 bedroom semi is two to three hours.
The Drilling Process
The drilling process does cause some vibration so pictures and ornaments should be moved for safety.
The installer will need to gain access to all rooms including attached garages. The installer must before and after installation, including any heating appliances.
The drilling process does create a little dust, but the installer will make sure to clean up after him to the best of his ability. Bad weather does hamper cleaning on occasions.
It will also be necessary to remove any vehicles from your driveway and any other objects near the outer walls to give him the best possible access to carry out the procedure.
The cavity wall procedure has a pattern of holes determined by the British Board of Agrement, to verify that it results in a complete fill.
Measurements are taken during the survey so that we know the amount of material required to correctly fill your walls. This will be checked against the amount of material used.
Ventilators on external walls
Ventilators supplying combustion air to fuel burning appliances must be safeguarded. Ventilators at ground level that ventilate below timber floors need safeguarding. The installer will check if they are sleeved. If they are not the installer will remove them and seal around them to stop them being blocked by the insulation.
You receive a guarantee called a CIGA, which stands for Cavity Insulation Guarantee Agency. This certificate guarantees workmanship and materials for 25 years.
We apply for it for you and CIGA will send it to you directly. It can take up to 8 weeks to be received by you.
A Warmer house
Your insulation will dramatically reduce your heat loss so you will be able to turn your thermostat down a little. Your property should still achieve the same temperature and your house should retain the heat longer.
It can also benefit you during a summer because the insulation blocks some of the suns heat thus keeping your house cooler.
