Keep the cold out – ways to insulate your home

What’s the best way to keep your home warm and reduce your energy bills? Insulate! Insulation makes your home easier and cheaper to heat and assists in keeping your home comfortable and healthy to live in. Chances are that your home has at least some insulation, and it is usually found in the ceiling. However, there are lots of ways to insulate your home.

Ways to insulate your home

Ceiling insulation is by far and away the most efficient way to keep warmth in your home. The onset of winter weather is a good reminder to check that your insulation is in place, and realign any areas that may have shifted out of place or replace any sections that have deteriorated. If your ceiling insulation is still in good condition but just isn’t keeping the house warm enough, consider adding a second layer. Remember to close attic manholes.

If your home has downlighters you may find that the ceiling insulation does not cover these – this is a safety precaution. However, you can now purchase downlighters that can have insulation over them and this can make a big difference to the efficiency of your ceiling insulation.

There are various types of insulation for under the floor – polystyrene, wool, polyester, or fibreglass. This usually comes in the form of blocks or pads to fit between the joists. It is recommended that underfloor insulation be fitted by a professional to ensure a good fit for the best performance. You will be amazed how much warmer your floors will feel!

Exterior walls can account for a huge loss of heat from your home and are best insulated at the time of construction. However, insulation may be retro-fitted during renovation. This usually requires removal of wall linings or the injection or ‘blowing’ of insulation through small holes.

Windows can account for up to 30% of the total loss of heat from your home. Installing double-glazing (and even triple-glazing in really cold climates) can reduce this heat loss and stop condensation forming. The cost of double-glazing may be prohibitive though and DIY window films can make a slight difference. Installing thermal curtains on your windows and external doors will help to keep the cold out and weather-stripping any gaps will stop draughts.

Draught excluders installed on doors can help to keep a room warm if you’re not heating the whole house. These can be easily homemade as a quick sewing project.

    A friend of mine had applied some bubble wrap to their windows to act as double glazing over winter. Apparently it worked a treat. We have a pretty well insulated house, but we could definitely do with something to stop draughts under doors. Great idea!

    I would kill for double or triple glazing! I definitely notice the cold from our windows and we have so many windows where the heat is lost. Unfortunately we cannot install underfloor as the gap isn’t big enough 🙁

    We are lucky enough that our house is about 10 years old and has double glazing and pink batts in the roof. But it can still get really cold over winter but we have a fire and heat pumps in the house for warmth.

    We are actually going through the bus at the moment to insulate it as we have pulled the roofing apart to see how much insulation is in it and its just a thin layer of foam. We are excited to get started on it this weekend and notice the difference ♥

    We live in a rental apartment in a commercial building (we are the only non-commercial tenant) but the building has ceiling insulation (we are on the top floor) and the landlord did put in a heat pump which is great. He also recently put some noise insulation under floor which is a type of insulation anyway. Can’t do the walls as it’s a triple brick building 🙂
