Glue Laminated Timber
JJ-Beam is a high specification engineered timber product made by gluing together strength graded timber laminations to make up larger sections and distribute the natural defects evenly throughout the volume. The laminations are finger jointed to allow long lengths to be formed. This results in a structural unit of great strength and dimensional stability.
Geographic availability

Application and typical uses of the product
Typical applications for glulam are beams, purlins, columns, lintels, rim boards or trimmers etc. In many instances glulam can be used to replace steel elements making installation and fixing easier
Breakdown of Product
100% timber (spruce strength graded timber laminations)
Embodied energy (Processing plant emissions). How much energy is used to produce the product? kWh per annum or kgCO2
8.594 kWh/kg (primary energy cradle to gate)
Thermal conductivity (k) W/m°C or Thermal transmittance (U-value) - W/m2°C (If applicable)
0.13 W/mC
Is the resource Renewable or Finite?
renewable
Does the material need to be processed further or treated by the user
Glulam is normally supplied untreated and prior to applying preservative treatment is exposed, advice should be sought from the manufacturer
Buildability - how complex is installation? What skill level is required?
Glulam can be installed using a number of standard fixings, bolts or metalwork connectors on-site. Specialist contractors may be required for larger complex projects as mechanical lifting equipment will often be required during site operations. Once installed, if the structure will not be weather tight for a prolonged period of time, the glulam should be protected from the weather to avoid excessive changes in moisture content, and associated dimensional changes
Types, textures, specifications and colours currently available
Glulam beams are planed on 4 sides, chamfered edges and can be produced in a wide range of sectional sizes and lengths. It is also available in both visible and non-visible quality dependant on whether the glulam is being exposed in the finished building
