British Larch Tongue and Groove Cladding

There are five profiles of British Larch Tongue and Groove profiles we supply which are:

  • 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

Our tongue and groove cladding is more versatile than the other profiles of cladding we supply because the majority of them can be fitted horizontally or vertically. This means that you get the right look for your project. Only IWC5 must be fitted vertically.

We supply British Larch as Fresh Sawn Merchantable grade. Larch is a knotty timber making it full of character. The colours of British Larch vary from a pale reddish-brown to Brick red. If you would like to keep the colour of the wood then you can treat your cladding with a UV protection oil so that it doesn’t weather to a silvery grey.

British Larch is a great timber which is great for outdoor use because it is durable and resistant to rot. British timbers are becoming more and more popular and our British Larch is a really good British softwood which is priced competitively and gives a characterful, traditional look to your cladding.

The British Larch Tongue and Groove Cladding we supply is usually provided in lengths of 3m and longer. We can provide exact lengths if you need them however we do ask that you call us (on 01889 597281) or talk to us on our online before ordering so that we can check with the supplier. If we confirm we can provide the lengths you need, please enter them into the “Special Instructions” box on the shopping basket page.

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:

Fitting Guidance

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

Breathable Membrane

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.

Fixing

** 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 or nail head when you fit the board to the batten. Look to leave a 3mm gap between the boards, rather than butting them up tight like flooring, 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.

All our claddings are provided untreated. Fresh sawn timber claddings are best left untreated and to go silver grey. There are a wide range of optional treatments available for different species of timber and we recommend talking to the excellent team at www.wood-finishes-direct.com, who know the most up-to-date information on all the newest treatment products.

Some commonly asked questions

Delivery times

Our timber is imported straight from sawmills on the continent. Our usual lead times are therefore 14 to 17 working days.

What are your delivery costs?

We calculate our delivery costs based on how far away you are from us, to get more information on this please check out our shipping costs page HERE.

Delivery day

Our delivery lorries visit different parts of the country on different days, so once your order is ready we will work with you to arrange a delivery day for when one of our lorries is in your area. We will always arrange the delivery day in advance with you.

Delivery times

We deliver weekdays Monday to Friday between the hours of 8am to 5pm. Our delivery vehicles will have multiple jobs on them which can affect the delivery time to you, depending on factors such as traffic and how long it takes to offload the previous jobs. The driver will call you in advance with an estimated time of arrival to make sure you'll be there.

Offloading

Aside from delivery locations that are priced on application, your delivery will be provided with means of offloading from the truck. This may be by HIAB (lorry with a crane arm), or by supplied manpower. The method will be determined by the haulage company we use based on your location and available options at the time. Please note, both offload options will drop your order to the side of the lorry, they won't be able to carry it around the back of a property, for example.

For areas that are priced on application, by default, we will quote for delivery on a flat-bed lorry that you'll need to arrange to offload yourself. We can quote for offloading on request, but to these areas it's usually prohibitively expensive, and cheaper for you to hire a forklift, or arrange to have enough people on-site to offload.

How do I place an order for cladding?

You can place your order online by working out your price above and adding your items to your shopping basket. You can then check out and your order will be processed securely and a confirmation email sent. Once your order arrives in our depot, we'll give you a call to arrange delivery.

Can I Order Samples?

Yes you can, you can order samples of certain timbers at www.iwood.co.uk/sample-request/. If the species you need isn't there please give us a call or talk to us on our online chat.

The timbers shown are planed all round samples and are not profiled.
