Thermory® Ash D45J 118 x 21mm

Thermory® only use high quality ash for their decking boards, harvested from well-managed forests in North-America where good growing conditions and strict drying standards are maintained. This range has been subjected to their ‘intense’ thermo-treatment’, which heats and steams materials up to a maximum temperature of 215°C, ensuring maximum stability and a dark, rich colour throughout the timber. This chemical free process also ensures a low moisture content, removes resin, reduces splitting strength and improves durability against decay. The end result is the transformation of responsibly sourced ash, a timber with limited exterior uses, into adecking material with class 1 durability credentials equal to Ipe and Teak.

Like any natural wood, Thermory® will begin to gently weather down once installed. This will include an attractive silvering/greying and the development of small, surface hairline cracks. Whilst many prefer to allow this appearance to develop, it can be checked through the regular application of Thermory® Thermo-ash oil.

The boards can be sanded back at any time to restore the original tones. The surface should be kept clean of leaves, pine needles and any debris that can hold moisture and attract mould and mildew. Barbecue spills, wines, condiments, dog nails, high heels, etc. can stain and scratch the surface. Most of these will fade and become less noticeable over time. Deeper scratches and stains can be blended with a light sanding.

Thermo Treated Ash boards should be installed using appropriate hidden fixing systems that allow for the boards to be fitted without creating weak points (such as drilling through timber).

Thermory PaCS^® ensures a flawless and durable deck with minimal installation time. PaCS^® creates a beautiful decking surface with no visible screws in the simplest way imaginable – boards are fastened to the clips with a simple click!

PaCS Strip is a fastening solution for PaCS decking. PaCS Strip is a six-clip strip that fixes three boards sideways onto one joist. These strips must be connected together and fixed to the joist, and the decking boards can then be easily snapped onto the clips. The strip will leave a 5-mm gap between the boards, and the clip thickness raises the board 5 mm above the joist to prevent wood-to-wood contact and ensure the required ventilation.
