Why does insulation keep your home warm?

When you’re looking for ways to keep your home warm beyond having the heating on all the time, the most common piece of advice given is normally to make sure your insulation is up to scratch. This advice is touted so often that many people don’t even stop to consider why does insulation keep your home warm, and is it really the best thing you can do to make most efficient use of your heating? We’ll take a look at a couple of the most common types of insulation and how they work to keep your home warm to help you decide if this is right for you.

Roof or attic insulation

Why does attic insulation keep your home warm?

Hot air rises, and if your attic isn’t insulated, you could lose up to 25% of your heating through the roofspace if you haven’t insulated it properly, or if your insulation isn’t the recommended thickness. The most common type of attic insulation is fiberglass, which is made up of millions of air pockets which helps to keep your home warm as it slows down how quickly the hot air rises through your home and escapes through the roof. You could see real savings in your energy bills from the first year you install attic insulation, so this is a very effective method of ensuring you get the most efficiency for your home heating oil spend.

Underfloor insulation

Why does underfloor insulation keep your home warm?

Older houses in Ireland can sometimes have suspended floors, which means there is a big gap between the ground and the floor where you could lose up to 10% of your home heating through. When air circulates around in this cavity, it can speed up the heat loss process, therefore filling it with insulation slows down the heat loss. You should also pay attention to any gaps around your skirting and seal these with caulk to prevent any further heat loss. Of course, the easiest way to quickly insulate your wooden or tile flooring with little spend is with a cosy rug or carpet on top to take the chill off your toes.

Wall insulation

Why does cavity wall insulation keep your home warm?

Heat loss through your walls can be slowed or prevented by reducing the amount of air in the gap (as air is a poor conductor of heat) by filling it with an insulating material. Cavity wall insulation is blown into the space to help keep your home warm, as this foam-like material contains lots of air pockets which help to slow the heat loss process through the walls. You could lose up to 30% of your heating through the walls in your home that don’t have any insulation, so while this is a costlier form of insulation it really could go some way in helping you save money on your energy bills in the long term.
