Timber Cladding: Machined On Site at Our Sawmill

Featheredge cladding, also called feather edge boarding or weatherboarding, is a tapered board fitted horizontally with each board overlapping the one below. It gives houses, barns, garages, garden rooms and sheds a traditional, rustic look and sheds rain well.

We machine our featheredge on site at our own sawmill in Corby, so boards in your order match in profile and taper. The one exception is painted featheredge, which arrives factory painted. Choose oak featheredge from our main range: green (fresh sawn) oak in Character Grade Oak at 24/6 or 28/8 and First Grade Oak at 24/6, or Air Dried Oak at 22/5.

You can also choose British Douglas Fir at 24/6 or 28/8, Redwood Thermowood and Radiata Thermowood, Black Painted Kiln Dried Nordic Pine and our lowest-cost Treated English Softwood.

Prices are per m² ex VAT, except painted featheredge, which is priced per linear metre. Work out how much you need with our featheredge cladding calculator. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby.

V tongue and groove cladding, also called V groove or V joint cladding, has a tongue and groove join with a chamfer on each edge, so every joint shows a crisp V shadow line. Every board is reversible, and it can be fitted horizontally or vertically. Fitted horizontally, put the tongue uppermost so water runs off.

We machine all our V tongue and groove on site at our own sawmill in Corby, so every board in your order matches in profile. For outside walls choose Air Dried Oak at 120 or 142 × 20 or 24 mm, Douglas Fir at 142 × 20 or 24 mm, or Thermowood at 142 × 20 mm, which suits inside and outside: Redwood Thermowood and Radiata Pine Thermowood. For interiors choose Kiln Dried Oak at 120 or 142 × 20 mm, Kiln Dried Ash or Kiln Dried Douglas Fir.

Prices are per m² ex VAT. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby during our opening hours.

Shiplap cladding, also written ship lap, has a rebate along each board so it overlaps the one below and sheds rain. Fitted horizontally, it gives clean shadow lines on houses, extensions, garden rooms and sheds.

We machine all our shiplap on site at our own sawmill in Corby, so every board in your order matches in profile and cover: 120 mm boards cover 110 mm and 142 mm boards cover 132 mm. For outside walls choose Air Dried Oak at 120 or 142 × 20 or 24 mm or Air Dried Douglas Fir at 142 × 20 or 24 mm. Redwood Thermowood and Radiata Pine Thermowood, both at 142 × 20 mm, suit inside and outside. For interiors choose Kiln Dried Oak at 120 or 142 × 20 mm or Kiln Dried English Ash at 142 × 20 mm.

Prices are per m² ex VAT. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby during our opening hours.

Shadow gap cladding is a modern timber cladding profile with a recessed channel between every board, so each joint reads as a crisp, dark shadow line. Each 142 mm board overlaps the next with a 36 mm tongue, leaving a 106 mm face and a 10 mm shadow gap. It can be fitted horizontally or vertically; fitted horizontally, put the tongue uppermost so water runs off.

We machine our shadow gap cladding at our own sawmill in Corby, so every board in your order matches in profile. For outside walls choose Air Dried Oak or Douglas Fir at 142 × 20 or 24 mm. For inside or outside, choose Redwood Thermowood or the clearer, Prime grade Radiata Pine Thermowood at 142 × 20 mm. For panelling indoors, see our internal shadow gap cladding.

Prices are per m² ex VAT. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby during our opening hours.

Half lap cladding is a traditional timber cladding profile where each board is rebated along its edges so it laps over the next, giving a flat face with a neat shadow line at every joint. It's fitted horizontally and suits houses, extensions, garages and garden buildings.

We machine our half lap cladding at our own sawmill in Corby. For outside walls, choose Air Dried Oak at 120 or 142 × 20 or 24 mm, Douglas Fir or English Sweet Chestnut, or the Thermowoods: Redwood Thermowood and Prime grade Radiata Pine Thermowood. For interiors, choose Kiln Dried Oak or see all our internal half lap cladding.

Prices are per m² ex VAT. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby during our opening hours.

Rebated featheredge cladding, also written rebated feather edge, is a tapered board that overlaps the next like roof tiles, with a rebate along the edge so it sits flat against the battens. The rebate adds stability and weather resistance. It's laid horizontally, with a 35 mm overlap as a guide when you work out quantities. Use our cladding calculator to get your quantity and price ex VAT.

We machine our oak and Douglas Fir rebated featheredge at our own sawmill in Corby. Choose Rebated Fresh Sawn Oak, Rebated Air Dried Oak or Rebated Douglas Fir in 150, 175 or 200 mm widths. For a factory-painted finish in black, white or grey, see Painted Nordic Pine or Premium Black Painted Nordic Spruce.

Oak and Douglas Fir are priced per m² ex VAT, and painted boards per linear metre ex VAT. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby during our opening hours.

Our internal timber cladding brings real wood to walls, ceilings, kitchens, bathrooms, garden rooms and feature walls. Oak, ash and Douglas fir boards are kiln dried at 20 mm so they stay stable in heated rooms, Thermowood is heat-modified for stability, and every board is machined on site at our own sawmill to our own profile drawings. Choose from kiln dried oak, English ash, Douglas fir and Thermowood. Tongue and groove and V tongue and groove give a neat, flush finish. For sloping ceilings, see our vaulted ceiling boards, and use 20 mm kiln dried trim boards to finish corners and openings. All prices are per m² ex VAT, and we deliver UK-wide in up to 10 working days on our own crane offload vehicles. Cladding for outside walls? See External Cladding.

Frequently asked questions

Why is internal cladding kiln dried?

• Kiln drying brings the moisture down before the boards are machined, so they stay stable in heated rooms rather than shrinking and opening gaps.
• Kiln dried oak is 8–12% moisture up to 40 mm.

What thickness is your internal cladding?

• 20 mm kiln dried across our internal range.

Can I use internal cladding on a ceiling?

• Yes. Tongue and groove boards suit ceilings, and our vaulted ceiling boards are made for sloping ones.

Is internal cladding supplied finished?

• No. All our cladding is supplied unfinished (apart from painted featheredge), so you can choose the finish.
• Oil, wax or lacquer it, or leave it natural.
• Our wood oils and finishes include Treatex Hardwax Oil Ultra, which suits interior walls and ceilings.

Waney edge cladding, sometimes called live edge cladding, is made from boards cut straight through the log, so each one has a natural, irregular bark edge on one side and a square edge on the other. The boards are fitted horizontally only, with the waney edge showing and each board overlapping the one below, for a rustic, handmade look on sheds, barns, garden buildings and feature walls.

We machine our waney edge cladding at our own sawmill in Corby. Choose Fresh Cut Oak for the classic look, which weathers to a silver-grey, or Fresh Cut Douglas Fir for a lower-cost, British-grown option. Both come in random widths of 150 to 300 mm, 19 or 25 mm thick, and random lengths of 2000 to 4000 mm.

Prices are per m² ex VAT. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby during our opening hours.

Tongue and groove cladding, often shortened to T&G, is a board with a tongue along one edge and a groove along the other. The tongue slots into the groove so the boards lock together for a flush, tidy wall or ceiling, indoors or out. It can be fitted horizontally or vertically; fitted horizontally, put the tongue uppermost so water runs off.

We machine our tongue and groove boards at our own sawmill in Corby. For outside, choose Air Dried Oak or Douglas Fir. Thermowood suits inside and outside: Radiata Pine Thermowood or Redwood Thermowood. For inside walls and ceilings, see Kiln Dried Oak and our thinner matchboard.

Most boards are priced per m² ex VAT, and matchboard and dungboards per board. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby during our opening hours.

Channel siding cladding, sometimes called channel cladding, has boards that overlap so a recessed channel shows between each one. The result is a bold shadow line along every board, which gives a wall clean, continuous lines. It's usually fitted horizontally, so the lines run the length of the building.

We machine our channel siding at our own sawmill in Corby. For outside walls, choose Air Dried Oak or Douglas Fir. Thermowood works inside and out: Radiata Pine Thermowood or Redwood Thermowood. For interiors, there are kiln dried oak, Douglas Fir and English ash boards.

All boards are priced per m² ex VAT. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby during our opening hours.

Rain screen cladding, also called rainscreen cladding or splayed cladding, is made of rhomboid-shaped boards. They are fitted a set distance apart on top of a waterproof membrane, which gives a modern wooden façade with bold shadow lines between the boards. Because the boards don't interlock, the membrane is essential. It's usually fitted horizontally, but it can also go on vertically or diagonally, so the lines run whichever way you want.

We machine our rain screen cladding at our own sawmill in Corby. For outside walls, choose Air Dried Oak or Douglas Fir. Thermowood works inside and out: Radiata Pine Thermowood or Redwood Thermowood. For interiors there are kiln dried oak and English ash boards.

All boards are priced per m² ex VAT. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby during our opening hours.

Board on board cladding, more commonly known as board and batten cladding, uses overlapping boards: wide boards are fixed underneath and narrower boards go on top to cover the joints. The overlaps create shadow lines and depth on a wall, and board on board is normally fitted vertically.

We machine our board on board cladding at our own sawmill in Corby. For outside walls, choose Air Dried Oak or Douglas Fir. Thermowood works inside and out: Radiata Pine Thermowood or Redwood Thermowood. For interiors there are kiln dried oak and English ash boards.

All boards are priced per m² ex VAT. We deliver UK-wide in up to 10 working days on our own crane offload vehicles, which we operate nationwide, or you can collect from Corby during our opening hours.

Timber boards for cladding a garden shed, workshop or outbuilding. For an economical way to cover a large area, choose Treated English Softwood Featheredge, pressure treated with Tanalith E for Use Class 3 (outdoor, above ground). If you would rather use untreated timber, we also stock Douglas Fir Yorkshire Boarding, Douglas Fir Matchboard, heavy-duty Douglas Fir dungboards and Lightweight Oak Featheredge. Featheredge is priced per m² and the Douglas fir boards per board, all ex VAT with VAT added at checkout. Not sure which to choose? Talk to our sales team on the live chat or call 01536 267107.

Agricultural cladding is timber boarding for farm buildings: barns, stables, livestock housing, machinery sheds and grain stores. We stock three Douglas fir boards for the job: Yorkshire Boarding, heavy-duty dungboards (stock walling) and Matchboard. Douglas fir is a strong, hard-wearing British softwood with natural durability, which makes these practical, low-maintenance boards for farm buildings that face the weather. Left untreated, they weather to a silver grey. All three are priced per board ex VAT, with VAT added at checkout. Not sure which to choose? Talk to our sales team on the live chat or call 01536 267107.

Set lengths is an add-on to your cladding order, not a type of cladding. Instead of the standard or random lengths on a listing, we supply your boards in the lengths you ask for, which helps cut waste and offcuts on site. Add Set Lengths (External Cladding) for outdoor cladding or Set Lengths (Internal Cladding) for indoor cladding, one for every square metre of cladding you are buying, then write the lengths you need in the order comments. Not sure? Talk to our sales team on the live chat or call 01536 267107.

Trim boards are plain square sawn boards that finish a cladding job: corners, edges, window and door openings, soffits and fascia boards. Each one is made to match our cladding in the same timber: fresh sawn oak, British grown Douglas fir, kiln dried English ash for indoors, and Redwood Thermowood or Radiata pine Thermowood. All come 44 mm or 88 mm wide in 1.2, 2.4 and 3.6 m lengths, priced per length ex VAT, with UK delivery or collection from our Corby sawmill.

Our cladding fixings are A2 grade stainless steel from Timber Titan, for fixing hardwood and softwood cladding, including pressure treated boards. Choose stainless steel annular ring nails in sizes from 1.85 x 31 mm to 2.65 x 60 mm, sold in 1 kg and 5 kg bags, or stainless steel cladding screws in 50 mm and 63 mm, plus low-profile self-drilling cladding screws. Not sure which to use? Talk to our sales team on the live chat or call 01536 267107.

Oils, preservers and paint to protect and finish your wooden cladding. Choose a Treatex oil matched to your timber, such as External Virgin Oak Oil, Cedar Oil or Douglas Fir Protection, a Barrettine wood preserver, or Woodtech Barnjacket Barn Paint, an opaque, water-based acrylic wood stain for barns, stables, sheds and cladding. Coverage, where the maker states it, is on each listing. Not sure what your boards need? Talk to our sales team on the live chat or call 01536 267107.

Our external timber cladding is made for outside walls on houses, extensions, garden rooms, sheds, barns and stables. We machine every profile on site at our own sawmill, apart from painted featheredge, so cover widths stay consistent from board to board. External oak and Douglas fir boards are air dried at 20 or 24 mm. Thermowood is heat-modified for stability without chemical preservatives, and treated English softwood featheredge is our lowest-cost option. Choose a traditional look with featheredge, rebated featheredge or waney edge. For a flatter face, choose shiplap, half lap or tongue and groove. For contemporary designs, there's rain screen, board on board, channel siding and shadow gap. Prices are per m² ex VAT, and we deliver UK-wide in up to 10 working days on our own crane offload vehicles. Cladding for inside? See Internal Cladding.
