Timber used for laminating is carefully selected for production and graded according to strict Prowood 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 PL12 glulam products are available in visual and non-visual utility grades. Pre-cambered beams are available on request.
Prolam PL12 has higher strength and stiffness properties than PL8 and enables you to achieve bigger spans with larger loaded dimensions.
For a similar span and loaded dimension, a PL12 can offer a smaller section where the space is limited or aesthetics are important.
Prolam PL12 beams are manufactured to the wide range of sizes specified by the Prolam Pro online specifier.
