Solid Spruce Double Door with Double Glazing

The SDD-3 Low 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 Low?

Anti-Warp Laminated Spruce Construction

All wooden components longer than 160cm are produced from laminated spruce, preventing warping and twisting under moisture and temperature variation. The result is a door that maintains its shape, seal, and smooth operation over the long term — even in exposed outdoor environments.

4+6+4 ESG Double Glazing

Toughened double-glazed units with silicone sealant deliver reliable thermal performance and safety. The ESG construction meets European safety standards, making this door suitable for residential and light commercial timber buildings.

Wind and Water Resistant Sealing

Rubber draught excluders along the door perimeter, combined with a rubber-sealed spruce casing, block air infiltration and moisture ingress. The aluminium threshold strip protects the base from wear and water entry at the most vulnerable point of any outward-opening door.

Fully Adjustable Hinges

Hinges can be precisely adjusted on-site using a standard allen key, compensating for any minor installation variance and ensuring an airtight, correctly aligned door leaf. Decorative black hinge covers provide a polished, finished appearance.

Yes. All hinges are fully adjustable using a standard allen key, allowing fine-tuning of the door leaf alignment and seal after the frame has been installed. Decorative black covers are supplied to conceal the hinge hardware once adjustment is finalised.
