Glulam is the process of lamination that maximises the benefits available in timber construction in a unique way. Glue laminated timber is an engineered structural material consisting of a number of graded, kiln dried and selected full length laminations. Laminated Timber is also noted for its inherent ability to withstand the effects of fire. It has a superior fire resistance rating when compared to steel. The process of manufacture is carefully controlled requiring conformance to internationally recognised standards; TimberLab’s plant is regularly inspected to ensure ongoing compliance.
TimberLab Glulam timber beams are load-bearing structural members for roofs, floors and other construction situations, e.g. bridges, posts, etc. Glulam uses stress rated, seasoned and selected timbers - usually Radiata Pine or Douglas Fir. In TimberLab’s unique system each single piece of timber is graded to ensure the design values are met. Glulam members are stronger weight-for-weight than other structural materials.
Finger jointing is an integral part of Glulam manufacture. TimberLab’s distinctive system allows the longest in-grade piece of timber to be processed through the finger jointer, meaning that the distance between finger joints in any one lamination can be up to 6m. The average distance is approximately 2.5m; finger joints in other systems can be only 100 – 300mm apart.
In this a way, multiple layers of timber (laminations) up to 34m long, not exceeding 45mm thickness are bonded together using suitable adhesives to provide a variety of sectional beam sizes. By building up large, strong members from a number of thin laminations, any size, shape or length can be manufactured.
