TECHNICAL
Red Stag TimberLab has been contributing to technical issues with Engineered Timber since our involvement in the original NZ Glulam Standards in 1972. The following up to date, comprehensive library of technical information provides guidance on a large range of issues relating to engineered timber solutions. These include Specifications, Characteristic Performance values, a large suite of technical data sheets & other items.
SPECIFICATIONS FOR GLUE LAMINATED TIMBER NZ
Glulam is a critical structural material and needs to be carefully specified to comply with the strength, service class and appearance grade required by the designer. This specification ensures compliance with the relevant design codes and can be used for your project.
SUSTAINABILITY
Red Stag TimberLab is reducing the dependence on non-renewable resources that produce materials such as steel and concrete by converting logs into attractive and efficient major structural elements.
FIRE PERFORMANCE
Laminated Timber is noted for its inherent ability to withstand the effect of fire. It has a superior fire resistance rating when compared to steel. This makes Glulam structures a safe choice for large public buildings. Safe evacuation of people is the most important aspect of fire safety. Because Glulam structures do not collapse under fire, safe evacuation is possible and fire fighters are able to gain access to the seat of fires preventing further damage. Rebuilding after fire has often been achieved by removing the charcoal layer from the Glulam beams while they are still in position and replacing the burnt out roof.
TREATMENT LEVELS
The long performance of engineered timber structures can be affected by exposure to various environmental hazards. While timber is largely inert to chemical contamination that may cause steel to rust, insect and fungal attack is possible under some conditions.
To protect from these conditions modern treatment methods can ensure durability. The attached table identifies the various conditions from interior use (where insect / termite hazards might exist) to marine exposure. The hazard levels are described and appropriate treatment levels detailed.
Timber is a natural product and resins are found in many types of softwood, particularly Radiata Pine. Click here for recommended preparation routines for painting of timber surfaces where resin bleed has occurred.
