Recommended Timber
For bifold systems, stability and weather resistance are essential. That’s why we recommend Accoya or Red Grandis:

- Red Grandis
We also frequently use Tricoya which is a mixture of MDF and Accoya dust, offering superior resistance to moisture, swelling and decay making it ideal for British weather.
Finish & Design
Our bifold doors are built for year‑round performance. They can be supplied with:
- Opaque factory‑applied finishes
- Translucent factory‑applied finishes
High‑quality microporous coatings protect the timber while achieving your desired aesthetic from natural wood tones to bold modern colours.
Glazing & Security
Your bifold doors must perform as well as it looks. That’s why our doors include:
- Double, triple or vacuum glazing
- Advanced weather seals
- Robust locking systems
These features ensure excellent security, weather resistance and long‑term structural stability particularly important for exposed or high‑traffic areas of the home.
