As hidden as insulation is behind the walls, up in the attic and under the floorboards, its benefits are not so obscure! You probably know by now (especially if you’ve read our blog before) that the right amount of insulation can help reduce energy bills and improve comfort all year round.
The key words there are “right amount.” If your home is not properly insulated or installed, then you’ll have a much harder time reaping the benefits of saving money and staying comfortable. The question of whether “too much of a good thing” crops up when there are concerns of going overboard with sealing a house and potential problems with doing so, such as moisture build-up and mold to polluted indoor air.
A house can definitely be under-insulated but today, let’s dive into the question of whether your home can be over-insulated.
First, let’s start with the basics: how does Insulation work?
During the winter, the air inside the home is warmer than the air outside. The insulation slows down the movement of energy from the warm area to the cold area, creating a thermal barrier that means your heaters or fireplace don’t have to work as hard to keep the home warm. The thicker the insulation, and the lower the U-value, the better this thermal barrier is and so the slower the heat will escape the home.
During a summers day when the temperature may hit 30 degrees, the air outside is generally warmer than the air in the home. With the heating off, the house warms up gradually through the day as the walls and roof absorb the heat of the day. But because the air outside is warmer the thermal barrier created by the insulation will again slow the movement of heat, but in the opposite direction. Warm air in the roof will not be able to penetrate into the home as easily, whilst insulation in the walls will prevent them from warming the home as quickly as well.
What about air quality if the house is too tight?
It is important for your home to have good air quality – poor air quality can be hazardous to health. Not all insulation is created the same. Insulating your walls with vapour resistant insulation, like we do, reduces condensation that is caused when the moisture from daily activities, such as cooking, washing, and bathing gathers on the surface of your walls. It’s an effective way to avoid the harmful effects of moisture in your home.
Insulation is vital for your home
Wherever you live and whatever the type of property, insulation is absolutely vital – especially with spiralling energy costs! And while there are potential risks of over insulating your home if you choose the wrong installer, there’s a much better chance you don’t have enough insulation, particularly if you’ve noticed:
• Higher than normal energy bills (without an increase in usage)
• Drafts or uneven temperatures from room to room
• Unusually warm second floor in your home
