Russwood recognise timber as the major truly sustainable building material of the future. We invest a great deal of effort promoting the many advanced uses of timber decking applications incorporating the use of performance-enhancing fixing systems.

Russwood secret-fix and face-fix systems for decking extend its longevity, improve appearance and reduce the requirement for maintenance. Moreover, contemporary fixing methods enable decking boards to be easily replaced and even reused which complies with the principles of environmental sustainability and circular economy.

In this blog we invite our readers to learn more about the benefits of using Russwood fixing systems for decking.

Garapa Decking with Slip-Resistant GripDeck®

Decking secret-fix systems

GleitFix®

The advantages of GleitFix® secret-fix system include eliminating the risk of water traps by over-driven screws; allowing air circulation between the decking boards and the joists and, if ever required, easy replacement of individual decking boards. The two-component (GleitFix® AE and GleitFix® GF) fixing system is made of reinforced fibre-glass compound extremely resistant to heat, frost and UV. The design allows the expansion and contraction of timber, preventing end and surface splits. The GleitFix® works with board widths from 90mm to 150mm and board thicknesses from 19mm to 30mm.

DielenFix®

DielenFix® provides a clean appearance without visible fixings and allows air to circulate freely between the underside of the decking boards and substructure joists. This results in enhanced durability of an optimally ventilated deck with no water traps which otherwise could lead to moisture damage. DielenFix® adds stability and prevents end and surface splits. Each board is fixed on its underside using one fixing on each side adding a design flexibility to use decking boards of non-standard widths for projects looking to make an impact.

SenoFix® (Thermopine decking)

SenoFix® also provides a fixing-free face and therefore a clean, refined surface. The risks of unsightly overdriven screws and resulting water traps are eliminated. SenoFix® can be used with Russwood RW215/RW214 profiles for Thermopine decking which offers outstanding dimensional stability. 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.

SenoFix® makes decking 50% faster to install than conventional face fixing when used with TerrassenFix® Clamp.

Decking face-fix systems

L-BohrFix® A4 & KompeFix®

Patented L-BohrFix® MB A4 screws are precision-milled from marine grade (316, also known as A4) grade stainless steel. This type of steel is especially well suited to use in decking where constant wetting and standing water is a concern or where the presence of chlorine or salt would cause other steel types to corrode and discolour. The sharp flanks of the screw thread allow optimum anchoring without causing the timber to split. The small diameter of the flush-drilling 3-step head allows for clean, consistent detailing.

Together with L-BohrFix® screws we recommend using KompeFix® which creates a well-ventilated decking structure. Sufficient ventilation shortens timber’s drying time which results in increased longevity. Additionally, KompeFix® compensates for the natural swelling and shrinking of the timber.

Decking substructure systems

JustiFix® with Thermopine joists

JustiFix® greatly reduces assembly time as it is height-adjustable from 35-500mm, making setting out and accurate levelling of the substructure a significantly easier and quicker task. JustiFix® avoids decay issues which would normally occur when timber underbuilding contacts the ground and reduces the probability of water gathering underneath. This enhances ventilation and therefore greatly increases the durability of the substructure and the boards.

For the substructure of decking, together with JustiFix® we recommend using 142x42mm Thermopine joists. The main advantage of Thermopine is its thermal treatment which provides great dimensional stability. The reduction in dimensional movement can be up to 40-50%, which is of particular benefit to substructure elements. Thermopine is significantly more resistant to moisture absorption than unmodified timbers, therefore shrinkage and swelling are decreased substantially.

JustiFix JK SF® with SymbioFix® joists

SymbioFix® system is an aluminium rail system used along with JustiFix JK SF® adjustable feet. The 5mm distance from the aluminium rail to the decking board, results in effective ventilation thereby eliminating potential decay. If required SymbioFix® system can be easily dismantled and reassembled which makes it ideal for events and temporary projects. With high load-bearing capacity and no substructure warping, the 1.1m lengths means SymbioFix® is endlessly connectable; simply click into JustiFix® JK SF adjustable feet, for fast fixing, resulting in 50% time saving compared with all - timber construction.
