Timber cladding has long been a popular choice for both residential and commercial properties, thanks to its natural beauty, sustainability, and versatility. Among the many cladding options available, rainscreen cladding has gained recognition for its modern look and high-performance functionality. But what exactly is rainscreen cladding, and why is it an increasingly popular profile for contemporary architecture?
This guide explores what makes rainscreen cladding unique, its benefits, common applications, and why timber rainscreen profiles, particularly in species like larch, cedar, and Douglas fir, are an excellent choice for forward-thinking building designs.
What Is Rainscreen Cladding?
Rainscreen cladding is a type of cladding system that includes a ventilated cavity between the cladding boards and the structural wall of the building. Unlike traditional cladding systems that sit directly against the building’s exterior, rainscreen cladding is designed to allow moisture and air to pass through the outer timber façade, helping to regulate moisture levels and improve the longevity of the structure beneath.
This technique acts as a barrier and a ventilated layer, reducing water penetration, promoting airflow, and enhancing insulation properties. The name “rainscreen” comes from the idea that it “screens” rain from reaching the structural wall behind.
How Rainscreen Cladding Works
A rainscreen cladding system typically consists of the following components:
- Timber cladding boards (installed with a gap between each board)
- Vertical or horizontal battens fixed to the structural wall
- A breathable membrane to protect the inner structure
- Ventilation gaps at the top and bottom to allow air circulation
The combination of these layers creates a high-performance system that allows water to drain, air to circulate, and vapour to escape, reducing the risks of rot, damp, and thermal bridging.
Timber Rainscreen Cladding Profiles
Timber is a natural material that suits rainscreen cladding perfectly, especially when sustainably sourced and properly treated. At The Larch Cladding Company, we supply high-quality rainscreen timber profiles in larch, cedar, and Douglas fir, each offering their own benefits in terms of durability, aesthetics, and sustainability.
Our rainscreen profiles feature a smooth, modern appearance with a narrow shadow gap between boards to provide visual interest while still maintaining excellent airflow behind the cladding.
Benefits of Timber Rainscreen Cladding
Superior Moisture Control
The ventilated cavity behind the cladding prevents moisture from being trapped against the building’s fabric. This is especially important in the UK’s wet climate, where excessive moisture can lead to damp, mould, and structural damage.
Improved Insulation Performance
The air gap created by the rainscreen system can improve the thermal performance of the building by reducing heat loss. It can also reduce the risk of thermal bridging and contribute to lower energy costs.
Long-Term Durability
By allowing walls to dry out more efficiently and minimising moisture retention, rainscreen cladding can extend the lifespan of both the cladding itself and the structure it protects.
Sustainable Choice
Using FSC®-certified timber like larch, cedar, or Douglas fir supports responsible forestry and reduces the carbon footprint of a project. Timber is a renewable material and one of the most environmentally friendly building options available.
Contemporary Aesthetics
Rainscreen cladding offers a modern, clean-lined appearance that’s ideal for both new builds and renovations. The consistent shadow gaps between the boards create visual rhythm and depth, making it a striking feature on any building.
Low Maintenance
Naturally durable species like larch and cedar require minimal upkeep. Left untreated, they weather to a beautiful silver-grey patina. Alternatively, they can be finished with oils or stains to maintain their original tone.
Best Timber Species for Rainscreen Cladding
Larch Rainscreen Cladding
Larch is an excellent choice for rainscreen cladding. It is naturally robust and resistant to decay, making it ideal for exposed settings. British-grown larch, like the Welsh larch we supply, offers a warm, golden hue and a tight, attractive grain.
Cedar Rainscreen Cladding
Western Red Cedar is valued for its dimensional stability, making it less likely to warp or split. It has a beautiful reddish-brown colour and offers exceptional longevity with minimal maintenance.
Douglas Fir Rainscreen Cladding
Douglas fir is a strong, versatile timber that works well for cladding. Its straight grain and light colour make it suitable for a wide range of finishes, from natural to charred.
Where to Use Rainscreen Timber Cladding
Contemporary Homes
Rainscreen timber cladding is a popular choice for modern homes looking to blend aesthetics with functionality. It’s often used to highlight feature walls, upper storeys, or entranceways.
Garden Rooms and Outbuildings
Create sleek, breathable exteriors for offices, studios, or garden rooms that require protection from the elements without compromising on style.
Commercial Buildings
Offices, retail spaces, and hospitality venues benefit from rainscreen cladding’s clean, architectural look and low-maintenance finish.
Public Buildings and Schools
Rainscreen cladding offers longevity, fire-resistance potential (depending on treatment), and sustainability, making it ideal for public buildings with high performance expectations.
Installation Considerations
- Rainscreen cladding must be installed with precision to maintain even gaps and airflow.
- Fixings should be stainless steel or galvanised to prevent corrosion.
- A weatherproof membrane and ventilation gaps are essential to performance.
- Always consult with a professional installer familiar with rainscreen systems to maximise the benefits of this cladding profile.
While The Larch Cladding Company does not offer installation services, we can recommend experienced trade partners if needed.
