SmartLVL 15 H2S 150 x 58 3.0m SL1515058H2S30

This 3.0 m length is a Tilling Timber SmartFrame SmartLVL 15 beam, 150 mm deep by 58 mm thick. Kiln-dried spruce veneers are laminated to AS/NZS 4357 and sold in fixed sections and lengths.

Cutting

• Do not resaw through the thickness.
• Depth rips must match a published smaller size.

Treatment

Glue-line H2S treatment is for interior above-ground framing south of the Tropic of Capricorn, protected from wetting and leaching, against borers and termites. Do not place it in the weather or where water can pond. The factory sealer sheds rain during storage and construction, when framed members may see weather for a limited time, usually not more than 3 months, and it does not totally waterproof the LVL. If the member will be exposed, order an H3 length instead.

Installation

• Joists, bearers, lintels, rafters, hanging beams, counter beams, strutting beams and underpurlins are sized from the SmartLVL 15 tables or an engineer.
• Design span runs to the centre of the required bearing, not across a thick wall.
• Restrain hanging, counter and strutting beams with blocking, a top tie or a galvanised strap.
• Do not skew-nail a rafter to an underpurlin parallel to the veneers, or birdsmouth that way.
• Inside AS 1684.2, one diagram allows one hole in any 1800 mm of span and the other allows three; otherwise ask an engineer.
• Heavier joints need a rated hanger rather than skew nails.

Storage

• Store packs flat and off the ground, on bearers at most four metres apart, under a breathable cover.
• Wet LVL loses strength in the short term while wet, and some thickness swelling may not fully recover after drying.
