Attic/Loft Ceiling Level

One of the most common applications for Sheep Wool Insulation is on the floor of the attic (or loft), referred to as ceiling level insulation. This application ensures that heat generated within the living space does not pass into the attic and escape. This application is also one of the most important as up to 35% of heat loss from a house can occur here.

To maximise the performance of insulation at ceiling level, a significant thickness is required. Ideally, this would be installed in a number of layers, covering the timber joists and reducing the opportunity for heat to escape through them (known as thermal bridging).

In houses with shallow joists, this might mean adding additional joists, or counter joists, if a floor is to be installed afterwards. Although this may mean additional effort at the time of installation, it offers a significant long term energy saving advantage.

Premium or Comfort insulation rolls are suitable for this application, with Premium giving a superior performance and Comfort being the lower priced. For the purpose of these calculations, Comfort has been used.

The images below show some examples of this type of application:
