Techlam Introduces New Sprucelam Beams for Interiors

Industry experts in structural laminated timber for over 25 years, Techlam saw a gap in the New Zealand market for an aesthetically pleasing, high strength laminated interior product. To fill that gap, Techlam has sourced a better visual grade timber that has superior structural properties to Radiata Pine. It meets appropriate NZ Standards, is more dimensionally stable, is price competitive and environmentally certified.

Not all people want to use treated timber, and in Canada for example, durability of timber is assured primarily through good design, natural resilience of the timber and only lastly timber treatment, ie. if the structure is designed correctly, timber treatment becomes of very minor importance.

Techlam has been careful to consider where and how the product should be used and have sought expert advice on the appropriate design and use of Sprucelam.

Techlam's PASS (Product Technical Statements or PTS) are available for download from the Techlam website and clearly detail the full scope, use and limitations of Sprucelam.
