Why Choose Timber Bi-Folding Doors?

Timber vs. Aluminium Bi-Folds

While aluminium is popular for its thin sightlines, Engineered Timber (Accoya®) offers superior thermal insulation, preventing the "cold bridge" often felt with metal frames. Timber also provides a more natural, premium aesthetic that complements London’s period architecture and garden spaces.

While uPVC has its place, timber offers unique advantages that make it an excellent choice for bi-folding doors:

Natural Beauty: Timber exudes a warmth and character that no other material can replicate. It adds a touch of sophistication and timeless appeal to any home.

Versatility: Timber can be crafted into a wide range of styles and finishes, allowing for customization to perfectly match your home's architecture and interior décor.

Durability: When properly treated and maintained, timber bi-folding doors are incredibly durable and can last for many years.

Sustainability: Sourced from responsibly managed forests, timber can be a sustainable and environmentally friendly choice.

Common Bi-Fold Configurations

Configuration Ideal Opening Width Best Use Case
3-Pane (3+0) 2.4m - 3.0m Standard kitchen extensions and dining areas.
4-Pane (3+1) 3.2m - 4.0m Includes a "Traffic Door" for quick daily garden access.
5-Pane (5+0) 4.0m - 5.0m Large structural openings and grand rear elevations.
