<---  Back to Calculators

Our loft roll insulation calculator will help you work out how many of each roll you require to insulate your loft space to your desired thickness. How many loft rolls do I need is often a question we get based on thickness of overall insulation which is made up of crossing layers of insulation roll.

The U value required is continually changing to offer more thermal efficiency, so please check to see what final u value you desire.





Loft roll insulation is important because it helps to prevent heat loss from the home, reducing energy bills and increasing voerall comfort. It also helps reduce noice levels from outside and within the home due to its density, which creates a quieter and more peaceful living envirnment. Additionally, loft roll insulation can help prevent the build up of condensation and mould, which can cause damage to properties and have negative health effects on the occupants.
