Sawn from slow grown small diameter logs, Thermopine® boards display tight grain figuring with an abundance of live (structurally sound) knots, in an equal mix of round and splay knots. Some knots may display cracks or chipped off edges. Our Thermopine® decking is profiled for use with SIHGA SenoFix®. The SenoFix® provides a fixing-free face and therefore a clean, refined surface. The risk of unsightly overdriven screws and resulting water traps are eliminated.
A major advantage of thermal treatment is its effect on the durability of the timber. Following the treatment process pine becomes a Durability Class 2 timber according to BS EN 350-2. This is the same durability class as oak. During the thermal process every cell of the timber is modified, with the treatment penetrating throughout the entire timber board.
The method with which the decking is fixed and detailed can have a major effect on its lifespan. Our fixing systems designed by Austrian Timber Engineers SIHGA, will make decking look and perform better for longer.
When combined with SenoFix®, the Thermopine® decking offers outstanding levels of dimensional stability. Compared to unmodified pine it can be up to 40% more stable. This means it stays flat and is significantly less affected by cupping or crowning when subjected to extremes of wetting and drying.
The heat treatment reduces the density by approximately 10% to 450kg/m³, making it relatively light in weight, similar to Western Red Cedar. Due to the reduced mechanical strength it is recommended that Thermopine® decking is secured with 400mm centres.
SIHGA’s SenoFix® secret fixing solution for Thermopine® is a tough, UV resistant and rust proof fixing, which permits movement (frequently the movement can be from the underbuilding joist and framework) and ensures the free flow of air around the boards. This avoids saturation of the timber and enables rapid drying of wetted decking, thus reducing the risk of slipping. The SenoFix® clips makes decking 50% faster to install than conventional face fixing (when used with TerrassenFix® Clamp).
The movement accommodated by the SenoFix clip eliminates the risk of squeaks developing. Squeaky decking is usually a result of face fixing the decking with screws directly to joists with no allowance being made for movement.
Brushing our Thermopine® creates a textured surface which enhances the unique grain and inherent natural figuring within each board. Wire brushes are used to pull out some of the softer spring wood, in-turn exposing the harder and typically darker coloured summer wood. The result is an aesthetically pleasing and characterful board that speaks of it’s natural origins.
GripDeck® is a highly effective slip-resistant solution which can be applied in-house to our Thermopine® decking. The specially bonded aggregate strips provides a long-lasting solution to slippery decking, being rated as “extremely low potential for slip” (BS7976:2002 Part-1 3 using the Stanley Pendulum Test). GripDeck® is equally suitable for domestic decking, as well as wear demanding commercial environments, providing excellent slip resistance in both wet and dry conditions.
Russwood’s Thermopine® is PEFC®-certified, meaning that it is sourced from well-managed forests.
