Shiplap cladding is a traditional cladding profile that has been commonly used in the construction of barns, sheds, outbuildings and inexpensive or seasonal homes.

Shiplap cladding

Shiplap is a profile that partially overlaps the adjacent board, creating shadow line effects, provides excellent weather protection and allowing for dimensional movement.

Shiplap provides excellent weather protection, especially when installed horizontally. The channel in shiplap allows water to run off quickly after exposure to rain, making it more suited to harsher weather environments than some of the contemporary alternatives.

A big advantage of a ‘lapped’ board (without a rebated joint) over a tongue and groove design is the ability to remove a single board if it becomes damaged or you need access behind it, rather than having to strip off multiple boards.

Historically this has been viewed as a more traditional cladding finish and is typically machined on wider boards than the more contemporary alternatives.

Wood durability

Durability is a measurement of how long specific species of timber would last if a 50mm x 50mm cross section was left in the ground unprotected. An untreated Oak beam, which is classed as 'durable’, for example, will last 15-25 years depending on environmental conditions. The following scale of durability was outlined by TRADA, the Timber Research And Development Association.

Durability Class designation Average service life
1 Very durable More than 25 years
2 Durable 15-25 years
3 Moderately durable 10-15 years
4 Slightly durable 5-10 years
5 Not durable Less than 5 years

Please select your preferred board width.

Cladding guide

It's worth noting that the width of your cladding will impact the price. Narrow widths result in more waste and additional workmanship so will be slightly more expensive per metre.

Please select your preferred board length.

Cladding guide

We aim to deliver at least 80% of boards at the lengths you have requested. The remainder will be mixed lengths – some longer and some shorter. A request for a high proportion of longer lengths will have a higher cost per metre because of restricted supply. A mixed length order will be the cheapest because of the ease of sourcing.

To keep delivery costs low we conform to standard UK pallet sizes.

Please enter the coverage you require in either linear or square metres.

Linear metres calculates the total metre run needed for a specific board width to cover a known square meterage. If you are not 100% certain of your calculations we suggest you include wastage at either 5 or 10%.

Please select your preferred wastage.

0% means you plan on having no waste and we will deliver precisely the linear or square meters you require. 5 or 10% wastage gives you a little leeway when trimming your cladding.

If you are unsure of the exact amount of linear or square metres you require we strongly recommend you add a percentage to take account of any 'wastage', otherwise you may not be getting an accurate representation of your costs.
