Every year our main mill on the continent shuts down for three weeks due to extended European holiday laws.
Tuesday 17th July 2019: Our loads of Oak Feather Edge Cladding are now full before the shut down. Lorry space from the sawmills for kiln dried European Oak is filling up quickly on a first-come, first served basis, so please place your order as soon as possible.
Please call us on 01889 597281 to see if we can fulfil your order from stock.
European Oak Tongue and Groove Cladding
We supply European Oak Tongue and Groove cladding in the following profiles:
- IWC1 - 19mm x 145mm overall, with a 135mm face - For horizontal or vertical fitting
- IWC2 - 19mm x 95mm overall, with an 88mm face - For horizontal or vertical fitting
- IWC3 - 19mm x 142mm overall, with a 125mm face - For horizontal or vertical fitting
- IWC4 - 19mm x 145mm overall, with a 125mm face - For horizontal or vertical fitting
- IWC5 - 19mm x 145mm overall, with a 125mm face - For vertical fitting only
All these profiles, apart from IWC5, can be fitted horizontally or vertically. IWC5 can only be fitted vertically.
You have a choice between our Prime Grade and Light Character Grade Oak for your cladding. Prime Grade Oak has very few knots and any knots in the wood will be very small whereas Light Character will contain more knots, however, these boards will still not contain any large dead knots.
Both our Prime and Light Character grade European Oak is kiln dried and so requires sealing before installation to protect it from moisture getting in.
European Oak is a good cladding timber because of its durability and natural resistance to rot. You will need to treat your timber before you fix it to prevent moisture movement. This will help to stop the oak from shrinking in the summer and expanding in the winter.
As standard we supply European oak tongue and groove cladding in random lengths of 2m and longer to fill the area you require. If you would like to specify the lengths you need please call us or talk to us on our online chat to make sure we can supply the lengths you want and then, if we confirm we can supply those lengths, you can tell us the lengths in the “Special Instructions” box on the shopping basket page.
If you require secret nailing on your cladding you will need to select our IWC3 profile.
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:
These fitting guidelines are only a rough idea on how to fix your tongue and groove cladding. We do recommend you employ a professional who has experience fitting tongue and groove cladding.
Be sure to read our treatment guidance as treatment needs to be applied prior to fixing your cladding
Consult a fitter to determine if your scenario would require the fitting of a breathable membrane between your wall and the cladding. 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. If you are fixing your cladding horizontally, your battens need to be placed vertically, at around every 600mm (60cm), and vice versa.
** Whether you use nails or screws, it's important that they are stainless steel, or silicone bronze ARS, so that the natural tanins in the timber will not corrode them. Never use iron nails for fixing timber.
To help stop the wood from splitting we recommend pre-drilling the timber and then holding it with the screw head when you fit the board to the batten. Look to leave a 3mm gap between the boards to account for any moisture movement and make sure that the tongue is facing upwards otherwise moisture will start gathering in the groove of the profile.
You can also use nails, preferably ring-shanked for extra grip, and again stainless steel so they don't corrode. For lower-density species like cedar, consider using nails with larger heads so the cladding doesn't pull through.
You can fit IWC 1,2,3 and 4 vertically or horizontally depending on the look you want from your timber. Whilst technically you can fit IWC5 horizontally, water can sit in the square channel, which is not recommended.
With each new row of cladding you add, it's preferred that you stagger the joins between each board so you don't create a visible seam.
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.
- 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.
- Wood Preserver - Helps to prevent rot and protects the wood from insect infestation and mould.
- 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.
