What is loft insulation?
Loft insulation is very straightforward; it is where you put insulation material between the joists or rafters in your loft to reduce heat leaving through your roof. It acts in the same way as a woolly hat. A woolly hat helps to stop heat from your body escaping through the top of your head. Likewise, the heat in your home will rise but loft insulation will help prevent it all escaping through your roof. Loft insulation usually takes a couple of hours to install. It is simply rolled out and laid flat across the loft floor, between and over the joists if they are visible.
Many lofts have some form of insulation in them, but the key for loft insulation is to have the right amount and to the right specification. If you don’t, what you currently have may be providing no support at all to the energy efficiency of your home and not preventing heat leaving your property.
How much does loft insulation cost?
According to the Energy Saving Trust, 2018, the typical cost of installing loft insulation in a detached home is £395. You could get this for free under the government’s ECO scheme.
How is loft insulation installed?
Loft insulation can be installed easily – and if you’re eligible under the ECO scheme, it’s free . All the installer needs is access to your loft and the ability to move around to lay the insulation.
If the whole loft is boarded, we can still lay the insulation by removing the boarding and if needed, we may be able to move around the things in your loft to lay insulation around them.
It shouldn’t take long as it’s usually straightforward, just a few hours to complete. Then once the loft hatch is closed, it’s all done and you can forget about it – until you start to see the savings on your energy bills.
What is loft insulation made of?
Typically, there are 4 types of loft insulation which may be installed:
Matting - Your typical roll of insulation, usually made up of mineral wool
Loose-fill - Loose material made up of mineral wool and cork which is poured between joists
Blown - Made up of mineral wool and fire resistant fibre, which is blown into specific areas (by professionals only)
Rigid boards – Can be used to insulate walls, floors and ceilings and is commonly made from polystyrene
