Our planed and treated shiplap cladding boards, perfect for exterior buildings and walls such as sheds, summerhouses, garages and play sheds to mention a few. These boards are made from a joinery grade Scandinavian redwood and therefore great quality boards that are both lightweight and durable. Our shiplap boards have been pressure treated using a green tanalith pressure treatment which ensures a long life and resistance to rot. They overlap each other when installed to implement a water tight and strong structure whilst also being visually superb and provide a clean, stylish look. The traditional look of the boards and the overlapping features creates shadow lines beneath producing an interesting and pleasant display.

At Ruby, to help with the instalment of our shiplap cladding, we have available either 50mm nails or Tongue-Tite Plus screws to purchase which are both suitable for all our cladding range. When installing your cladding, we recommend starting at the bottom and working your way up. Try to make sure your first board at the bottom is exactly level as this will make the rest of the job much easier and more efficient. .

Ruby UK - Timber

Please Note: All timber products are finished in metric and that softwood is a natural product that can twist and warp through changes of climate conditions. We advise customers not to install or apply any further treatment until the timber is fully dry, as this could cause the timber to split and warp. Timber sizes can also vary due to the weather conditions before dispatch. Please allow for up to 5mm variance. As all our timber is stored outdoors you may receive moist timber, this is perfectly normal. This will not affect the structural integrity of the timber.
