Tongue and groove with a s-joint provides further demarcation and accentuation of the gap between boards than TG&V. It is typically fixed vertically although may also be fixed horizontally.

TG&S cladding

TG is the abbreviation for tongue and groove which refers to the interlocking edge of the boards. TG&S refers to the square joint or more prominent ‘shadow gap’ that is created through greater demarcation of the individual boards.

Tongue and groove cladding is one of the most versatile profile types available because of its wide range of uses including gates, garden screens, fencing and cladding. It is typically fixed vertically, although often used horizontally as well in addition to mixed orientation cladding to break up a large cladding expanse. TG&S cladding looks particularly impressive when illuminated at night.

The interlocking nature of tongue and groove boards make them easy to fit and weatherproof.

A notable downside of tongue and groove cladding is the difficulty of removing or replacing boards once in place.

TG&S provides a right angled edge for a harder appearance, but we also provide TG&S Weathered with a 45 degree angle either side of the join to give a softer appearance.

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

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.
