How to Install Insulation

At all times insulation must be laid directly on the ceiling between the beams. It is essential to remember insulation laid over the beams is a waste of money as the heat will build up between the insulation and the cavity space below.

Insulation must be fitted end to end in the roof space. Leave no air gaps and make sure to cover the entire roof space. Fitting the insulation between the beams and cutting the insulation slightly wider than the beams is essential. In this way, the insulation will seal the ceiling from the hot air above or the cold air below.

The insulation can be torn to fit between the main beams. Ideally, Isotherm must be split across the width. In this fashion, we can rip the layers to install directly on the ceiling between the joists.

In loft Rooms, we fit the insulation to the side walls as well as the ceiling space above. The result is a sealed off block that reduces heat flow in or out as much as 90%.
