Cavity Wall Insulation
What is Cavity Wall Insulation
Installing Cavity Wall Insulation, if your home has cavity walls, can be one of the most effective ways to improve your home's energy efficiency whilst reducing your energy usage.
Most homes built in the last 100 years comprise two walls with a small space between them - the cavity. Homes from the early 1990s should have been built with the cavities insulated.
​
Unfilled cavities let heat escape and may account for up to 30% heat lost from your home. This means that your home is not as cosy as it could be and that your are using more energy to heat your home than is needed.
Is my home suitable?
We will undertake a technical survey of your home to ensure that it has a cavity, to confirm that the cavity is empty and that it is suitable for Cavity Wall Insulation.
​
In some instances, where the cavity is too narrow (less than 50mm wide); there is rubble in the cavity; the access is limited or the walls are exposed to wind driven rain (usually coastal areas) cavity wall insulation may not be possible.
How is it installed?
If walls are suitable, and require, cavity wall insulation then an accredited installer will undertake the works.
​
The insulation is blown into the cavity from the outside of the property (ensuring any vents etc. are blocked) through drilled holes. The holes are then filled back in to match the wall.
​
Cavity Wall Insulation usually takes around two hours to install, but this depends on the size of the property and ease of access.
Loft Insulation
What is Loft Insulation?
The Energy Saving Trust advises that a quarter of your home's heat is lost through the roof of your property (if you have a roof) so making sure that your loft is insulated is a really effective way to make your home warmer and reduce energy usage.
​
Installed correctly loft insulation pays for itself many times over in itrs 40 year lifetime.
​
A good form of loft insulation is mineral wool that forms a barrier between the loft and the roof to prevent heat escaping.
Is my home suitable?
We will undertake a technical survey of your home to confirm that the loft is uninsulated, or does not have the correct depth of insulation, and that it is suitable for Loft Insulation.
​
In some instances, if the loft is damp; has a protected species living in it (bats) or the loft hatch is too small we have to deal with this first.
How is it installed?
The Loft Insulation that MTVH are offering will be laid between the joists - the horizontal beams that make up the floor of your loft - then another layer is laid at right angles to cover the joists and provide the required depth to ensure your loft is well insulated.
​
If there are items stored in the loft etc. our Retrofit Assessor and Installer will discuss what can be done to work around this.
​
Once the insulation is installed it is very important that it is not squashed down as this will reduce its insulation value.
