Energy Efficient Measures in Housing

Cavity Wall Insulation
 
Filling the gap between the two walls of a house with an insulating material decreases the amount of heat that escapes through the walls. It can help create a more even temperature in your home, help prevent condensation on the walls and ceilings and can also reduce the amount of heat building up inside your home during summer hot spells.

Solid Wall Insulation

Solid walls lose even more heat than cavity walls. The only way to reduce this heat loss is to insulate your walls on the inside or the outside. This will help create a more even temperature in your home, help prevent condensation on the walls and ceilings and can also reduce the amount of heat building up inside your home during summer hot spells. The thickness of the insulation needs to be between 50 and 100mm and is usually installed where there are severe heating problems or the exterior of the building requires some form of other repair work, thus providing the opportunity for adding insulation.

Floor Insulation

Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists.

Double Glazing

Installing double glazing can cut heat loss through windows by half. Double glazing works by trapping air between two panes of glass creating an insulating barrier that reduces heat loss, noise and condensation.  While it can be expensive to install double glazing throughout your whole house, draughty rooms should be prioritised.

Draught Proofing/Air Tightness

Air tightness testing measures the flow of air within a building. The aim is to identify areas within the building which are experiencing a heat loss.
