FAQs
1. What is Shadow Gap cladding?
Shadow Gap cladding features boards installed with a 10mm recessed groove between each panel, creating sharp shadow lines for a modern architectural finish. The design also improves airflow and moisture control behind the cladding, enhancing longevity and performance.
2. Is British Larch suitable for exterior use?
Yes. British Larch is naturally durable (Durability Class 3) and highly resistant to rot, insects, and moisture. It performs exceptionally well outdoors without the need for chemical treatment.
3. Does Larch cladding need to be treated?
Treatment is optional. Left untreated, Larch will weather beautifully to a natural silver-grey patina. However, applying a UV-protective oil or wood stain will help maintain its warm reddish tones and extend its lifespan.
4. How long does Larch Shadow Gap cladding last?
With correct installation and periodic maintenance, Larch cladding can last 2030 years or longer, depending on environmental exposure and care.
5. How should Shadow Gap cladding be installed?
Boards should be fixed horizontally with stainless-steel screws or nails, starting from the bottom up. Each board overlaps the next by 10mm. Always leave ventilation gaps and use treated battens to ensure moisture can escape. A full installation guide is available for reference.
6. Can Shadow Gap cladding be used indoors?
Yes. While primarily used for exteriors, Shadow Gap cladding can also be installed internally as a design feature, offering a contemporary, textured wall finish in garden rooms, offices, or hallways.
7. What fixings should be used?
Only use stainless-steel screws or nails. Galvanised or mild-steel fixings can react with the timbers natural acids, causing black staining or corrosion over time.
8. How does British Larch compare to imported timber?
Home-grown British Larch tends to have a more open grain and rustic character with visible knots, whereas imported species (like Siberian Larch) have a tighter grain and lighter tone. Both are durable, but British Larch offers a more natural, traditional aesthetic and a lower carbon footprint.
9. How much waste allowance should I factor in?
Allow for 510% additional material to account for cutting, trimming, and natural timber variation. This ensures consistent coverage and a professional finish.
10. How should Larch cladding be maintained over time?
To keep cladding in top condition:
-
Clean annually to remove dirt and debris.
-
Apply UV oil once or twice a year to preserve colour.
-
Inspect fixings and joints regularly for tightness.
With simple care, your cladding will continue to perform beautifully for decades.
