European Oak Rainshield Cladding

We supply European Oak Rainscreen cladding in our IWC8 profile which can be fitted horizontally.

We provide Rainshield cladding in our kiln dried prime and light character grade Oak. Both grades are highly suitable for cladding with the choice coming down to your personal preference on how you want your cladding to look. Prime grade is a cleaner timber with very few knots whereas the light character will have more knots.

Due to our European Oak Rainscreen cladding being a machined and kiln dried product you will need to treat your timber to make sure that there is minimal movement from moisture entering the timber. Without treatment the timber will be subject to shrinking in the summer and expanding in the winter. We recommend that you treat your cladding before applying it to ensure a complete seal.

Your European Oak Rainscreen Cladding is supplied in random lengths of 2m and longer. You can request longer lengths if necessary however please call us on 01889 279 018 or talk to us on our online chat. If we can supply the lengths you need please outline your requirement in the “Special Instructions” box on the shopping basket page of the site.

Treatments

Be sure to read through our treatment information by clicking on "Treatment Guidance" above. It talks about sealing, preserving and protecting the timber from the sun's UV rays. Here are quick links to the products we recommend:

• Wood Preserver Basecoat - Barrettine Premier Universal Preserver
• UV Protection to Delay Weathering

Fitting Guidance

Our fitting guidelines are designed to give you a starting point on how to fit your rainshield cladding and we recommend that you consult an expert fitter to advise on your actual scenario.

Please note: One of the edges of our rainscreen profile has a steeper angle than the other. The profile is designed to be fitted with the steepest angle at the top, so the gap between the boards is widest at the front exposed side, and smallest at the back.

Be sure to read our treatment guidance as treatment needs to be applied prior to fixing your cladding.

Breathable Membrane

Rainshield cladding should be fitted on top of a breathable membrane, because it is designed to be fixed with gaps around it. This membrane stops rain getting to the wall, but allows moisture to escape, helping to prevent internal condensation and mould that can come with it.

Treated Softwood Battens

Treated softwood battens (available from our cladding accessories pages) are most commonly used to fix to the wall (or on top of the breathable membrane) to then fix your cladding to. For rainshield cladding, which is fitted horizontally, your battens need to be placed vertically, at around every 600mm (60cm).

Fixing

When fitting your timber to the battens we recommend pre-drilling the holes to avoid splitting the wood and then hold the board with screws. Rainshield cladding boards are designed to sit on top of each other and we recommend leaving a 12mm gap in between them on the front face.

Unlike other profiles of cladding, many people line up the joins on each row of cladding to create bold lines for a modern look.

As already stated, these are just ideas to get you thinking about installation and you should consult a professional installer before fitting your cladding as every scenario is different.

Treating Timber Cladding

All of our timber cladding is provided untreated.

For best results, cladding should be treated before it is installed to ensure application of the treatment on all sides and ends of the boards.

We recommend Wood Finishes Direct for all of your treatments. We have found them to be well priced and their telephone support and advice is second to none. We highly recommend giving them a call.

The following information is from Wood Finishes Direct in relation to treating timber cladding.

When it comes to treating your timber cladding, there are three areas of protection to consider.

1. Sealing against moisture movement - Sealants are used to help prevent moisture entering the wood causing it to expand. Kiln dried timber like European Oak will definitely need to be sealed, and for other timbers it is highly recommended.
2. Wood Preserver - Helps to prevent rot and protects the wood from insect infestation and mould.
3. UV Protection - The ultraviolet rays of the sun slowly bleach external timbers. UV protection oil helps to keep the natural colour of your timber for longer and prevent it from turning silvery grey so quickly. Some people like their timber to weather and prefer the silvery grey look so it’s completely down to you.

The following links will take you straight to the products on Wood Finishes Direct's website:

Product to Seal and Preserve

To address Sealing and Preserving, they recommend applying one or two coats of "Wood Preserver Basecoat - Barrettine Premier Universal Preserver" before installation to seal against moisture movement and protect it from mould and insects.

Product to Protect from UV Rays

Then to optionally delay weathering, two coats of OSMO UV Protection Oil. There are different colours of OSMO UV Protection Oil available, with names like 'Cedar' and 'Oak', but these colours are to make other timber look like the stated species. We recommend the 420 clear version which interferes the least with the natural colour of your timber.
