Cavity wall insulation is installed by drilling holes in the mortar in the outer layer of the house, and ‘injecting’ special thermal material into the cavity between the two outer walls. This material fills all of the space in the wall, creating many pockets of air. This stops convection from happening, which is the process of heat transfer caused by freely-circulating air. In addition, the pockets are excellent at retaining heat, and work to stop heat from passing through the house’s walls. Once all of the walls are filled, the holes are sealed with mortar of the same colour as was already there, so they are hardly noticeable. The process does not take very long, is done from the outside of the house, and does not make a mess.
Loft insulation involves laying thick rolls of insulating material in the loft space of a house, between the joists of the roof. This insulating material prevents heat from escaping from the home to the outside. Laying loft insulation is a fairly straightforward process which takes no longer than a couple of hours, as in most cases it does not involve any major construction work.
Installing an insulating jacket on a hot water tank is quite simple, although it is important to ensure that it is done properly, as any loose spots or gaps could reduce the efficiency of the jacket. The jacket should be snug and secure, but not compressed as that makes it less effective. If a jacket is already fitted, an installer can check that it is working efficiently and is not damaged, and replace if necessary.
Draught proofing involves installing special devices on a home’s doors and windows. This process can be completed in a very short amount of time, depending on the number of doors and windows in a home. When draught proofing, installers will check that each fixture is working effectively by testing for draughts. The fixtures attached to doors and windows are long-lasting and highly durable, and will not need to be replaced for very long periods of time.
