Solid Spruce Double Door with Double Glazing

The SDD-5 is a premium outward-opening timber double door for garden buildings, summerhouses, and log cabins. Made from a 45mm solid spruce profile, it delivers a clean, natural look with reliable structural strength.

Engineered to Resist Warping and Weather

Components over 160cm are made from laminated spruce to reduce warping and seasonal movement while keeping a solid-timber appearance. 4+6+4 double glazing with silicone sealing improves thermal performance, while rubber draught seals on all edges and a rubber-sealed spruce casing help block wind and rain. An aluminium threshold strip protects the base from wear and moisture.

Why choose Double Door SDD-5?

Anti-Warp Laminated Spruce

All timber components longer than 160cm are manufactured from laminated spruce, preventing warping while maintaining the appearance of solid wood. This is particularly important for double doors where leaf alignment is critical to long-term performance and weathertight closure.

4+6+4 Double Glazing

The double-glazed units provide effective thermal separation between interior and exterior, reducing heat loss through the door's glazed panels. Silicone sealant ensures the glazing units remain weathertight.

Adjustable Hinges

Hinges can be adjusted in the field using a standard allen key, allowing the door leaves to be precisely aligned after installation. Decorative black covers are supplied, ensuring a clean, professional finish without exposed hardware.

Weather Sealing

Rubber draught excluders are fitted to resist both wind and water ingress, complemented by a rubber-sealed spruce casing. An aluminium strip protects the threshold from wear and moisture.
