How does Loft Insulation Stop Conduction and Convection?
Are you aware that you are losing a quarter of your heat from the roof of your house? This is adding to the 25% of overall heat loss in the UK. For this purpose, loft insulation is the ideal choice here. It can prevent heat loss and avoid spending your money on huge utility bills.
But have wondered how loft insulation lowers the heat loss from your roof.
Let’s learn more about it in the following article
How Does Loft Insulation Prevent Heat Conduction?
When you use a heater or a central heater, vast amounts of heat tries to escape from your roof. There’s no way you can stop this heat loss.
The heat from your roof escapes through convection and conduction methods. However, if you install loft insulation, it will bring down the heat loss significantly. When you insulate your roof, this insulation traps the heat inside the loft helping you to stay warmer for a longer period. It also helps to keep you warm from the cold air that tries to enter your home. This means that you do not need to heat your home for keeping the room temperature the same in every part of your house. Throughout the year, it enables you to save extra pounds of money in your pocket.
How Loft Insulation Prevents Heat Convection?
Your loft loses more heat as most insulating materials are bad conductors of heat. These insulating materials stop the air circulation inside your house by the convection method. However, you can reduce this heat loss by using spray foam insulation. For insulating your cavity wall, you need to follow this same method.
How can you Stop Conduction and Convection?
Cavity wall insulation – The insulation material comprises few small pockets of trapped air in between them that helps in lowering conduction and convection. Moreover, the insulating fibers stop the trapped air to circulate within causing the convection process through process.
The working process of insulation reduces the transfer of heat helping it to move in three different ways: convection, conduction, and radiation.
The Thicker The Better
Putting extra layers of thickness into your spray loft insulation makes it perform in a better way. Adding thicker layers to your loft insulation acts as a strong barrier in trapping the heat from leaving your home. Think it like this way, the thicker your jacket, the warmer you feel, just like a jacket.
Even you can use few simple ways to reduce heat loss and heat transfer. You can include extra curtains, carpets, and draught excluders to stop convection and conduction. To reduce heat loss from the windows, you can use double glazing on your windows. Double glazing windows have a vacuum or air trapped in between these double panes of glass. However, keeping a vacuum in between the glass panes, there will be no convection or conduction. You can reduce convection by creating the double glass panes with air as this offers little room for the air to escape from the panes. Since air is a bad conductor of heat, therefore, you can expect fewer chances of heat loss through conduction.
