68mm Tilt-and-Turn Timber Window with LowE Double Glazing

The GW-2 is a premium timber window made for wooden garden buildings, log cabins, and outdoor structures where thermal performance and long-term durability are essential. Built from finger-jointed and laminated pine wood with a 68mm profile, it delivers structural strength and stability.

Precision Hardware, Superior Weatherproofing

Fitted with a high-quality tilt-and-turn mechanism from the MACO brand, the GW-2 opens inward. The thermal rain protection rail shields the frame from moisture ingress, while rubber draught excluders along the perimeter provide wind and water resistance.

High-Performance Glazing

The two 4mm tempered glass panes are separated by a 16mm cavity (4+16+4) filled with Argon gas, which provides better insulation than air. One pane features a microscopically thin coating that reflects heat, enhancing energy efficiency by reducing thermal transfer (LowE). The silicone sealant ensures the unit remains airtight and watertight throughout its life. Overall, the composition achieves a U-value of 1.1.

Protective Details That Last

A black metal sill protects the lower wood casing from rain splash and ground moisture — a detail that significantly extends the window’s service life. The GW-2 is compatible with Dadsons’ range of log cabins and garden structures, and is available as part of a complete kit or as a standalone component for resellers.

Why choose Premium Window GW-2?

High-Performance Thermal Glazing

The 4+16+4 LowE ESG+Argon double glazing unit achieves a U-value of 1.1, significantly reducing heat loss through the window. This makes the GW-2 suitable for use in insulated garden buildings intended for year-round occupation.

MACO Tilt-and-Turn Mechanism

Fitted with a MACO brand tilt-and-turn mechanism, the GW-2 opens fully inward for easy cleaning or tilts at the top for controlled ventilation.

Durable Laminated Pine Profile

The 68mm profile is constructed from finger-jointed and laminated pine. Dimensional stability and resistance to warping and checking. The layered construction reduces movement caused by seasonal humidity changes, maintaining a reliable seal over time.

Comprehensive Weatherproofing Details

A black metal sill protects the lower casing from rain splash and ground moisture, while rubber draught excluders around the perimeter minimise air infiltration. The spruce casing is finished with rubber sealants for a fully weatherproof assembly from the factory.
