Double Layer Ceiling Solution
Our two-layer solution includes a dense first layer, ensuring the expected thermal performance is still delivered when compressed. Learn more below.
We are seeing greater use of a two-layer system, often with traditional R3.6. However, this reduces thermal performance as the:
- weight of the second layer compresses the first layer
- thickness of the first layer sitting above the adjacent truss chords creates a channel for air flow.
The Comfortech® two-layer solution uses a:
- first layer of high-density Pink® Superbatts® insulation that is the combined height of the truss chord and the gap to the top of the ceiling batten. This layer would be either 110mm for a 90mm truss chord, or 160mm for a 140mm truss chord.
- second layer of over-width (460mm wide) Pink® Superbatts® insulation, installed at right angles to the first layer.
When the two layers are installed, the thermal bridge is completely closed, and the insulation performs as modelled.
