On Friday 20th November 2020, iWood's telephone system is being upgraded and we expect some downtime on the phones at some point during the day. Please email us on firstname.lastname@example.org if you have any trouble getting through on the phones, but we hope for a speedy switchover.
Covid-19 - 23/11/2020 - Just a note to say iWood Timber will remain open again through this lockdown as we supply the construction industry.
We're currently experiencing a high volume of orders, and with Covid restrictions in place,
we're currently working to a lead time of 14-28 working days
(some products have longer lead times as described in their individual descriptions).
These profiles are available once you select a species below.
Tongue and Groove cladding boards fit together on the long edges (like floorboards), can be fitted vertically or horizontally (depending on the profile you choose) and provide a modern, uniform look. We offer five different profiles for you to choose from once you've selected a species below.
Choose a species:
All of our Tongue and Groove Cladding is machined to match a profile of your choice and is available in a variety of species. We highly recommend T&G cladding because of its added security benefits of having boards that fit together rather than overlapping and increased weather protection that it brings.
There are five standard tongue and groove cladding profiles that we work to which are:
This is the most popular cladding we supply and is a traditional T&G board which can be fitted either horizontally or vertically. IWC1 is 19mm thick and has a 135mm face.
This is similar to IWC1 with the main difference being that the face width of the board is 88mm rather than 135mm.
IWC3 is a V Jointed tongue and groove cladding which is suitable for secret nailing. The profile has a 125mm face, is 19mm thick and can be fitted either vertically or horizontally.
IWC4 isn’t quite V-jointed but it does have a half-V channel to help with water run-off (making it similar to a shiplap profile). This profile can be secret nailed and is suitable for horizontal or vertical fitting. The face width of the board will be 125mm.
IWC5 is the only profile we recommend is fitted vertically only because of the square channel in the boards. IWC5 can be secret nailed and has a 125mm face with.
You can find more information on all of our Tongue and Groove Cladding profiles when you select a species above. When you have selected your species and worked out a price you can see alternative prices from other species so that you get the timber most appropriate to your budget.
Popular Tongue and Groove Cladding
Western Red Cedar is the most popular tongue and groove cladding we supply and it’s easy to see why. Cedar is one of the most remarkable timbers we supply, it’s durable and looks amazing with its various array of colours.
Tongue and Groove boarding is also probably what you're looking for if you're searching for Sarking or Panelling.
