We all want to live comfortably in our homes, and part of that requires good insulation. Many homes already have insulation, but the products available today are far superior to those from times gone by. So, if you’re building a new home or renovating your old one, here’s all you need to know about insulation.
Why Do You Need Insulation?
High quality insulation gives you an increased level of comfort in your home all year round. Air moves around the home in a certain way. For example, warm air tries to move into colder areas. This means in summer, the heat from outside is always trying to get into your home. In winter, you might be running the heaters constantly, but that warm air will always try to move to a colder place, such as outside.
Insulation aims to prevent this unwanted movement of air, and it has plenty of overall benefits. When you’re able to trap cool or warm air where you want it, you can save a lot of money on heating and cooling.
Getting into your roof cavity and laying down some good quality insulation batts is perhaps the easiest insulation job in the home. Access to the roof cavity is often pretty simple, so you can get up there, measure what you need and install it yourself.
Ceiling insulation should have a heat resistance, (or ‘R’) rating of 2.5 – 6.0. This will ensure best results, especially if you choose high-quality products. When installing ceiling insulation, don’t forget to tidy up around areas like chimneys, vents and air ducts. If you don’t cover these gaps, air will still have an easy escape route out of your home.
Wall insulation is a little more difficult, because you need access to the wall cavity. That’s why it’s best to install insulation in both internal and external walls during your home’s construction stage. However, if that ship has sailed, you might choose to wait until you’re doing some renovations.
If neither of these are an option, you may need to consider blow-in insulation. You can still install it yourself, but it’s often easier to call in the experts. They’ll cut small holes in the wall, blow in the insulation, and seal the plaster. You’ll need to do a bit of painting, but it’s still a lot less invasive than tearing down a whole wall.
When shopping, look for batts with an ‘R’ rating of 1.5 – 2.7.
If you choose to install some highly rated underfloor insulation, you get more benefit than just preventing heat loss. Good floor insulation should also have sound absorption qualities, meaning you can reduce the noise of footsteps. This ‘walking noise’ is common in all homes, particularly those with exposed floorboards, but underfloor insulation with great acoustic performance can help limit it. Most floor insulation should have an ‘R’ Rating of 1.7.
