Description
Bring a sleek, modern aesthetic to any exterior project with our Scandinavian Redwood Shadow Gap Cladding. Machined in-house from premium joinery-grade redwood, these boards are designed to deliver a clean, contemporary finish with long-lasting durability.
Each board features a precision-cut shadow gap profile that creates strong linear definition and striking visual depth. As the boards interlock, a consistent recessed line forms between them, giving façades a crisp, architectural appearance. This profile is perfect for transforming sheds, garden rooms, summerhouses, garages, and feature walls into stylish, modern structures.
Every board is green pressure treated to ensure resistance against rot, fungal decay, and moisture. Backed by a 15-Year Treat Right Warranty, you can count on excellent long-term performance in any outdoor environment. With smooth planed surfaces and reliable machining, this cladding offers both visual appeal and ease of installation.
Free samples are available so you can assess finish, quality, and suitability before ordering.

Frequently Asked Questions
1. What is Shadow Gap cladding?
Shadow gap cladding is a modern timber profile where each board is installed with a uniform recessed gap, creating a clean, linear shadow line. This produces a sleek, contemporary look ideal for modern garden rooms, exterior façades, and feature walls.
2. What is the face coverage of the 140mm x 21mm Shadow Gap board?
The effective face coverage is 130mm, allowing for accurate calculations when estimating materials for your project.
3. Is this cladding suitable for exterior use?
Yes. The boards are fully green pressure treated, making them ideal for outdoor installations exposed to weather, moisture, and temperature changes.
4. How long does pressure-treated Scandinavian Redwood last?
With proper installation and basic maintenance, treated redwood cladding typically lasts 10–15 years, supported by a 15-Year Treat Right Warranty.
5. Can Shadow Gap cladding be used indoors?
It can be used indoors for decorative features, but it is primarily intended for external cladding due to the pressure treatment and ventilation-friendly profile.
6. What fixings should I use with Shadow Gap boards?
Stainless-steel screws or nails are recommended to prevent staining and corrosion, ensuring a clean finish and long-lasting hold.
7. How do I install Shadow Gap cladding?
Boards should be installed horizontally with the recessed shadow joint exposed. Fix securely to treated battens, leaving expansion gaps as recommended. A full installation guide is available for step-by-step support.
8. Do the boards require additional treatment after installation?
Pressure treatment protects against decay, but applying a UV oil or stain can help preserve colour and reduce natural greying over time.
9. Can the boards be cut to size?
Yes. Boards can be cut on-site using standard woodworking tools. Bespoke cutting is available upon request for an additional fee.
10. What projects is Shadow Gap cladding best suited for?

Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

Garden Storage
My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.
