Timber I-Beams are often specified over standard solid timber framing to reduce thermal bridging and increase span capacity, however I-Beams create voids that are difficult to insulate using standard insulation products. Terra Lana I-Beam fillets friction-fit within the voids to ensure maximum thermal performance.
Terra Lana's I-Beam fillets are the only specific insulation solution available for timber I-beams. Fillets are manufactured from New Zealand wool along with thermal bonding technology using polyester to create a robust, structurally stable product that will never slump nor lose its loft over the lifetime of the building. It is BRANZ appraised, and comes with a 50 year warranty to meet the durability requirements of the New Zealand Building Code.

240mm hyJOIST | 160mm | R0.9 | 35mm |
