Premium Spruce Double Door with Double Glazing

The SDD-3 is a premium outward-opening timber double door for garden buildings, log cabins, garages, and summerhouses. Built from a 45mm solid spruce profile, it delivers a traditional timber look with reliable structural strength.

Built to Last

Components over 160cm are made from laminated spruce to reduce warping and seasonal movement while keeping the appearance of solid timber.

Weather Performance

The door includes 4+6+4 ESG double glazing, sealed with silicone for dependable thermal separation. Rubber draught seals around the perimeter help block wind and rain, and an aluminium threshold strip protects the base from wear and moisture.

Adjustable hardware

Fully adjustable hinges (set with a standard allen key) support accurate alignment during installation and over time. Black hinge covers and a spruce casing with rubber gaskets complete a clean, weather-tight finish.

Why choose Double Door SDD-3?

Warp-Resistant Laminated Spruce Construction

All components exceeding 160cm in length are manufactured from laminated spruce, preventing warping over time while maintaining the natural appearance of solid timber. This ensures the door continues to operate correctly and seal effectively throughout its service life, even in changing climatic conditions.

Effective Weather Sealing

Silicone-sealed double glazing units, spruce casing with rubber sealants, and rubber draught excluders fitted around the full perimeter provide reliable resistance to wind and water infiltration. An aluminium strip is fitted at the threshold to protect the base of the door frame from wear, moisture, and mechanical damage.

Adjustable Hinges

The SDD-3 comes with fully adjustable hinges operable with a standard allen key, enabling precise alignment during and after installation. This is particularly valuable for timber buildings that experience seasonal movement.

Double Glazing 4+6+4 ESG

Toughened ESG double-glazed units with a 6mm air gap provide thermal separation and enhanced safety compared to standard single glazing. The units are sealed with silicone sealant to prevent moisture ingress within the glazed assembly.
