Premium Glazed Pine Door

The GD-3 is a premium single external door made specifically for timber garden buildings, log cabins, summerhouses, and garden offices. Constructed from finger-jointed and laminated pine with a 68mm profile, this door delivers exceptional structural rigidity and long-term dimensional stability in demanding outdoor conditions.

Professional-Grade Security and Performance

The GD-3 features a high-quality MACO 3-point locking system, paired with adjustable MACO hinges for accurate alignment and reliable long-term use. It opens outward and includes rubber draught seals to block wind and rain, making it a strong option for year-round installations.

Thermal Efficiency

The double glazing provides excellent thermal performance while keeping the interior bright. Two 4mm tempered glass panes are separated by a 16mm cavity (4+16+4) filled with argon gas, which insulates better than air. One pane has a thin Low-E coating that reflects heat to reduce thermal transfer and improve energy efficiency. Silicone sealing, plus a spruce casing with rubber gaskets, improves weathertightness and helps minimize heat loss around the door. Overall, the assembly achieves a U-value of 1.1.

Ready for Professional Installation

Supplied with an aluminium threshold strip for protection and a fully finished spruce casing, the GD-3 integrates seamlessly into Dadsons’ range of timber structures. With an external frame width of 1054mm and height of 2072mm, it suits a wide range of standard cabin openings. All components are delivered ready for straightforward on-site fitting.

Why choose Premium Single Door GD-3?

3-Point Security Locking

The GD-3 is fitted with a high-quality 3-point lock from MACO, a trusted European hardware manufacturer. This multi-point locking system distributes clamping force evenly across the door frame, enhancing both security and weathertightness under load.

68mm Laminated Pine Construction

Finger-jointed and laminated pine construction at 68mm profile depth delivers superior strength and resistance to warping compared to solid sawn timber.

Adjustable Hinges

Adjustable hinges from MACO allow for precise three-dimensional alignment during and after installation. This is particularly valuable for timber structures that undergo natural settling, ensuring the door continues to close and seal correctly over time.

Full Weatherproofing Package

Rubber draught excluders provide a tight seal against wind and water infiltration, while an aluminium strip protects the threshold from wear and moisture. The spruce casing with rubber sealants completes a fully weatherproofed installation-ready unit.
