One major decision you’ll have to make is whether you want a warm or cold loft — phrases that are misleading because a chilly loft is hot in the summer and frigid in the winter.
The only insulation required for a cold loft is between the floor joists, which prevents heat from entering the space. This has the advantage of being inexpensive and simple to set up grants for loft insulation. However, it exposes the loft to temperature swings and moisture. If you plan to store goods that are sensitive to either or utilize the space for activities, a chilly loft is not the best choice. Insulation is separated between the loft floor and the bottom of the roof in order to create a warm loft.
Blanket insulation
The most common type of loft insulation is foil-backed felt, which comes in rolls of rock, glass, or mineral fiber (we use Earthwool by Knauf, which is a great environmentally responsible option). It’s usually the cheapest option and provides decent all-around insulation, particularly between joists. It is the simplest to install, however, it is not ideal for the roof.
Insulation with loose-fill
This sort of insulation is made up of grains of cork, cellulose fiber, mineral wool, or even recycled newspaper that are loose and lightweight. It can be used to supplement or replace existing insulation. The biggest disadvantage is that it is insecure and can be extremely messy!
Sheet insulation
The best approach for insulating the house is to use firm boards made of synthetic or natural materials. This is the best solution for insulating the underside of your roof. The boards provide excellent insulation for your loft space and can also be painted. The disadvantage is that sheet insulation is usually the most expensive.
Blown fiber insulation
Blown-in loose materials of various types between joists; this is great for hard-to-reach areas but isn’t a complete solution, especially in a draughty attic. It’s also pricey and requires skilled installation.
The type of insulation you choose for your loft will primarily be determined by how you want to use it. As well as any unique obstacles posed by the shape of your loft. And you can also get benefits from storage heater replacement grants.
