Truss Ceiling Insulation
Our truss roof blanket insulation is designed to maximise truss roof insulation effectiveness in a variety of installation options. Precut blanket slabs are available to fit 900mm centre rafters and are supplied in 1.2m lengths.
Truss wool blankets can be used as a single layer or double layer to maximise R-Value and to reduce thermal bridging in truss roofs.
Retrofit Truss Roof Insulation
Terra Lana Truss Roof Ceiling wool insulation is installed after ceiling construction in new or retrofitted truss roof spaces.
A second layer can be installed over the first layer and rafters or as a single layer over the top of the rafters (to mitigate against thermal bridging through rafters).
Single layer
Roll blanket installed as a single layer bridged over the top of rafters to reduce heat loss through rafters.
Single layer segments
Segment slabs are installed precut to width between rafters to achieve R-Value.
Double layer system
A second layer can be installed perpendicularly over the first layer and rafters to increase R-Value and reduce heat loss through the rafters.
This further enables full ceiling coverage out to the roof space edges.
