Prolam T&G Flooring is manufactured to AS/NZS 1328, and are designed to comply with B1, B2, C and F2 of the NZ building code.
Prolam T&G Flooring is structurally engineered timber elements with high strength, dimensional stability, good load carrying capacity, superior fire resistance, and are manufactured from select quality pine timber. The beauty of Prolam T&G Flooring is that it gives you a very low profile floor cross section, as well as an attractive ceiling all in one. All timber used for laminating is carefully selected for production and graded according to strict Prolam specifications.
All timber stock is kiln dried, to 13% average moisture content, to ensure efficient bonding in the gluing operations. The laminations are machine finger jointed if required, with glue being cured by state of the art European press systems and controlled temperature. Prolam T&G Flooring is manufactured to the range of sizes below, and is specified by the span tables in the Structural timber guide (Pg79).
