Wooden sliding wall WP67

Atmospheric wooden sliding walls

If you fancy enjoying your pergola longer in the evenings and into the year, whilst also protecting yourself against rain and wind and from prying eyes, our wooden decorative walls are the right choice to make. Our wooden sliding walls will have you instantly create the desired ambience and give you full privacy!

Durable Thermowood slats

The individual panels slide horizontally in one or two directions. The sliding frames are made from extruded aluminium and the slats from ecologically sourced Thermowood, Radiata Pine.

Protection against sun and wind

Wooden sliding walls are not only a stylish addition to your pergola, but they also offer privacy and a cosy atmosphere. Our walls are made of thermally hardened wood which is extremely weatherproof.

Optional screen fabric

As an option, the sliding panel can be finished with a screen fabric, giving you an attractive, beautifully finished panel that offers greater privacy whilst also keeping insects out. The screen fabric is fitted facing outward.

Mix & match your colours

Frame profiles and top rail can be painted in numerous colours:

  • Standard: in various black and white shades and corten steel without a surcharge
  • Optional in all RAL colours
  • Choice of 7 standard colours for the screen fabric

Walls made of ecological Thermowood

Thermowood is an eco-friendly alternative to tropical hardwood. Heating European coniferous wood in a kiln for a protracted length of time changes the wood’s structure and durability. The composition of the sugars and resins in the wood change. The cell structure and moisture percentage of the wood also changes, giving it the same sustainable properties as tropical hardwood. It is also resistant to rot, mould and rain.

Why natural cooling

Our mission statement, “We Believe in Natural Cooling,” lies at the heart of all our efforts. We consider smart sun screens to be the most natural and energy-efficient way to block heat. Compare it to a tree providing shade: just as you seek natural cooling under the branches of a tree, sun screens keep the sun out and your home, patio and workplace pleasantly cool. They offer natural air conditioning for your home which is healthy but also environmentally-friendly.
