Roof insulation boards, which are also called roof insulation panels, are different insulation types that are tailor-made for pitched and flat roofs. The most common roof thermal insulation material is PIR. Polyisocyanurate is one of the most mass-produced insulation materials. It is popular because it has a thermal conductivity value of 0.022 W/mK, making it one of the best materials for trapping heat inside your home.
Insulation boards for loft roofs do not have to stand alone. You can use additional products to improve the efficiency of insulation boards. Lots of people use foil and acrylic tape to seal the space between boards. This ensures that the thermal properties of the boards are not compromised.

Around 25% of the heat in your home is lost through the roof. People buy roof insulation boards when they want to improve the overall thermal envelope of their spaces roof. They are ideal for both domestic and commercial uses.
Some roof insulation board suppliers create general-purpose boards. The Celotex Insulation Board range contains general-purpose boards that can be used in floors, walls and roofs. They can even be installed under floorboards and in cavity walls. These PIR boards are rigid, lightweight, and have a low-emissivity foil facing to reduce heat loss.
General purposes boards are a good choice for people who want all the thermal benefits that come with PIR boards without having to research specific, purpose-built panels.
Pitched roofs are characterised by being steep. In general, they are more thermally efficient than a flat roof because there is a gap between the flat interior and the pitched exterior which allows for ventilation.
