Terra Lana wool insulation samples

Skillion

Skillion ceiling cavities can have a higher risk of condensation occurring. Terra Lana insulation is hygroscopic (can absorb and release moisture vapour) so it can help to mitigate condensation risks.

Truss

Supplied as a single or double layer, or as a top-up layer, this truss roof insulation is designed not to slump, or lose loft, and is naturally safe to handle and healthy in the home. It manages moisture, which maintains thermal performance.

I-Beam

Timber I-Beams create voids that are difficult to insulate using standard insulation products. Terra Lana timber I-Beam fillets friction-fit within the voids to ensure maximum thermal performance.
