Installing efficient insulation can reduce the amount of heat that escapes from your home, helping to keep your house nice and warm when it’s cold outside. This means you don’t need to switch on the heating or air conditioning as often, which can result in a significant reduction in your energy costs. And that’s always good news. But before you get too carried away, there are some things you should know to ensure you get the most from your insulation.   

Today, we’re going to get you up to speed on the right way to insulate your home.

Insulate the right areas

When you think of insulation, you probably think of the ceiling space – and with good reason. Up to 45 percent of heat is lost through the roof, so this is where you should insulate first. Most roof insulation materials prevent the movement of heated air, and in turn, leaking heat. However, warmth can also be lost through the walls. Wall insulation can help you to save as much as 20 percent on your energy bills. Regardless of the local climate, both roof and wall insulation are essential to stop heat escaping.

Ensure it is installed correctly

It’s important not to compress insulation at the edges of a roof. If this happens, the air pockets become reduced and the insulation won’t be as effective. Gaps in insulation can also affect the thermal performance by up to 50 percent, so ensure you don’t leave any open spaces. Furthermore, you should ensure the insulation doesn’t get damp or wet. Water and water vapour will fill the air gaps in the insulation and reduce its resistance. 

Use the right materials

Glass wool is the preferred material and is relatively cost-effective, mainly because other materials need to be treated with fire retardant and moisture-resistant chemicals. Plus, glass wool is often made from recycled materials, making it an environmentally-friendly option. However, not every material is suitable for every home. You’ll need to find out what’s best for your climate and building construction.

Know your R-values

Not only do you need to select the right type of insulation for your home, but you must also consider the insulation’s R-value. Otherwise known as thermal resistance, the R-value is the insulation’s ability to resist heat flow. In fact, getting the R-value right is more crucial than the thickness or material of insulation you choose. Each climate has different recommended R-values, so do some research and find out what is right for your local area.  

Make the most of your insulation

The best insulation in the world won’t be of any use if you’re letting heat out through gaps in windows, doors and so on. Be sure to plug up any draughts around the home before installing your insulation. Check less obvious areas, such as electrical outlets, TV lines and mounted air conditioners. If you’re about to move into a newly built property, consider installing a wall wrap and sealing it with tape to tackle air leakages.
