Cladding
What is shiplap cladding?
Shiplap cladding is made from wooden panels that overlap, creating a smooth and flat surface. This design makes it far more weather resistant than traditional overlap methods, helping protect buildings from the elements.
What is cladding used for?
Timber cladding is a versatile option for both internal and external applications on domestic and commercial properties. There are many reasons why people choose cladding, from style to performance.
Benefits of cladding:
- Appearance: Timber is naturally attractive, with warm colouring and unique grain patterns that add character.
- Weather resistance: Designed to protect against rain and wind, timber cladding reinforces a building from the outside in.
- Thermal insulation: It helps retain heat inside, reducing energy consumption and keeping your home or workplace warmer.
- Acoustic insulation: Timber naturally absorbs sound, lowering noise levels that pass through the structure.
- Environmentally friendly: Our timber cladding is sustainably sourced and recyclable, with a low carbon footprint compared to other materials.
Types of cladding:
We supply a wide range of high-quality timber cladding boards in several popular species, including:
- Cedar
- Redwood
- Larch
- Pine
- Ash
PTGV
This traditional style of timber cladding has a tongue and groove profile with a v-joint and smooth, planed finish. Each board interlocks securely, creating a strong and resilient system.
Shiplap cladding
Similar to tongue and groove, shiplap cladding boards fit tightly together for strength and reliability. The difference lies in the profile: the slanted design allows rainwater to run off easily, enhancing durability.
