External Slat Wall Panels are a lightweight and durable and manufactured using a combination of hard wood fibres and recycled plastics. The use of this mix of materials means the panels can be used on both exterior and interior installations. It is weather and waterproof and gives an aesthetically pleasing and low maintenance finish to any area. Composite products are widely used as a better alternative to traditional timber alternatives. They provide protection from the elements and add thermal insulation.
External Slat Wall Panels are extremely easy to install. We have full installation instructions available showing ‘how to’ in a step by step guide. Designed and manufactured using an interlocking system, the panels are lightweight and durable and can be used in a number of situations.
Temperature changes can cause composite board to expand or contract. We recommend that the boards are left for at least 48 hours to acclimatise to the surrounding temperature before install is started. It is not recommended to install the panels in extremely hot or cold temperatures.
No specialist tools are needed to install the panels. The panels can be installed using the same tools as would be used to install timber panels.
The panels are designed and manufactured using the highest quality materials to withstand the elements and reduce fading and weathering. There may be a small percentage of fading in the weeks following installation, however this will be minimal due to the high quality resin used in the timber effect finish.
Unfortunately not. As with all surfaces, regular cleaning will ensure the look and integrity of the panels will remain and reduce the risk damage. We have a simple care and maintenance guide available on our website outlining the basic requirements to keep your panels looking perfect and performing as expected.
Being manufactured from a composite material, the panels will not rot or splinter.
The panels are designed to mimic the effect and look of real timber so there is a variation in colour and grain to enhance the real timber look of the panels.
The panels are an engineered product so will not be impacted by insect. Although not prone to mould and or fungus, we recommend regular cleaning and maintenance to ensure there is no build-up of spores.
The panels should be stored on a flat, level surface which supports the length of the board. It is recommended to store the panels on a pallet to ensure they are not sat directly on wet or cold ground. Either inside or a cool shaded spot is best.
As composite products will expand and contract with surrounding conditions, you should not seal the installation and an allowance should be made for air flow. Also allow some air flow between the panels and the surface when fitting trims.
The panels have a 10 year Domestic Manufacturer Warranty. Warranty Registration must be applied for within 48 days of the purchase of the panels and installation instructions followed to ensure successful registration. Warranty Registration is via a link on our website. Images of the base surface, joist install and installation of the panels will be required, along with proof of purchase, in order for the Warranty to be registered successfully.
Our products are available nationwide through our network of Builders Merchants or through our Website.
