Why is Draught Proofing Important?

The good news is that there are lots of quick and easy ways to reduce heat loss at home. Not only are these energy efficient, but you’ll be improving your comfort whilst reducing bills.

Draught proofing your home is one of the most effective ways to reduce heat loss and keep your home warm.  It’s also one of the cheapest ways to save energy and money. A draught is a current of cool air which may come in through doors, windows, your roof or floorboards. 

A small amount of ventilation is useful within the home and can act to reduce condensation and damp – by allowing air in when needed. But draughts are often uncontrolled and if too much air is getting in, there will substantial heat loss.

In order to draught proof your property you’ll want to block any gaps that are letting cold air in and warm out. It means that the next time you turn your heating on, you’ll be using less energy and saving money.

Tips for Draught Proofing your Home...

Foam strips, chimney draught excluders, and excluder brushes can all prevent too much ventilation from accessing your home. Cold air can get into your home through gaps around windows, doors, letter boxes and holes in building fabric. Most draught excluders are easy to fit and some can come with self-adhesive stickers.

We’ll discuss below the best options for each area in your home...


Windows and doors are one of the easiest ways for cold air to access your home, especially if they are old.  If you don’t particularly want to replace your windows there are some other cheap and easy solutions. 

For windows that open out, you can draught proof by buying strips to stick around the window. These can either be self-stick foam strips, which are easy to install but may need replaced often. The other option is metal or plastic strips with attached wipers and brushes strips.

The latter will cost you a little more however they are long lasting.


When it comes to doorways you may need to draught proof both internal and external doors – it’s a worthwhile exercise and will save a lot of heat loss.  For external doors there are a couple of areas you need to be aware of; the keyhole, letterbox, bottom of door and window gaps.

For your keyhole you can install a small metal disc cover to stop air coming in. If your letter box is letting in a draught you might want to buy a letterbox flap or brush strip. You can use the same to tackle gaps at the bottom of your door.

Window gaps can be fixed with fit foam or any type of strip that we mentioned above.  Internal doors may need draught proofed if they lead to any room that isn’t usually heated, for example a wash or spare room. This can be easily done with a long shaped draught extruder.

Loft Hatch

One area that can often be forgotten about is the loft hatch or door to your attic. This is another place that you can easily insulate to make your home heat and energy efficient. The best way to insulate this area is with self-adhesive strips or metal and plastic ones.

A well insulated loft can reduce your energy bills by a large amount, and it can also work to keep your home cool and well ventilated in the summer.

Floor Boards

If you have gaps in your floor boards, a draught may be getting it. To draught proof your floor boards you could consider carpeting the room as a long term solution. However if this is not an option there are plenty of floor board fillers to choose from.

You can fill holes or cracks in your floor by filling the gap with squirting filler. As floor board tend to move and can expand with heat you should pick a filler that is silicone based. This will include flexible fillers, decorator’s chalk or mastic type products.
