Solid Spruce Exterior Door with Double Glazing

The SD-4 is a timber exterior door for log cabins, garden houses, and other timber buildings. Built from a 45mm spruce profile. The design is clean and practical, with a natural light-spruce finish and visible wood grain. A large glazed section in the upper half brings in daylight, while the solid lower section uses vertical timber boards for a classic cabin feel.

Built to Last

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 and weather resistance. Rubber draught seals run around the full perimeter, and the spruce casing includes rubber gaskets for a tighter finish.

Full Package

Black hardware (hinges and lever handle) adds a crisp contrast against the pale wood and keeps the overall look simple and modern. Adjustable hinges (set with a standard allen key) allow precise alignment over time, with black covers for a clean finish. An aluminium threshold strip protects the base from wear and moisture.

Why choose Single Door SD-4?

Anti-Warp Laminated Spruce Construction

All components over 160 cm in length are manufactured from laminated spruce, combining the appearance of solid timber with superior dimensional stability. This ensures the door maintains its fit and function across seasons without warping or binding.

Double-Glazed Panels for Thermal Performance

The SD-4 features 4+6+4 mm double-glazed units with silicone sealant, providing effective insulation and reducing heat loss through the door face. The glazing configuration is well-suited to Northern European climatic conditions.

Full-Perimeter Weather Sealing

Rubber draught excluders run the full door perimeter, preventing wind and water infiltration. The spruce casing is fitted with rubber sealants, and an aluminium threshold strip protects the base from wear and moisture ingress.

Adjustable Hardware

Hinges are fully adjustable using a standard allen key, allowing precise alignment after installation. Black decorative hinge covers are included, providing a professional finish without additional hardware.
