Insulating your home can save you hundreds of pounds
a year on fuel bills, according to EST. Without it, up to a
third of the heat you pay for can be lost through the roof,
walls, windows and oors, so insulation will make your
home greener as well as cheaper to run.
Homes can lose a quarter of their warmth through the
roof, so insulating your lo is one of the simplest and most
e ective ways to save energy - it can save you
and the materials last for decades, so it pays for itself.
Homes built a er
usually have e ternal walls
made of two layers with a space between them. Cavity
wall insulation fills that gap, reducing heat loss. he
installer drills small holes and blows in insulation
material, such as beads, granules, stone wool or
e panding polystyrene foam. Houses built before
tend to have solid e ternal walls, rather than cavity
walls, in which case e terior wall insulation is an option.
Insulation material is fi ed to the outside, then covered
with render, cladding, weatherboard or tiles.
Spray foam insulation is becoming increasingly
popular and can be used to insulate roofs, lo s, walls and
oors. or a ualified installer, visit nia uk.org.
