Premium Tilt and Turn Wooden Window for Garden Houses

GW-3 is a premium tilt and turn wooden window designed for wooden summerhouses and garden cabins that require reliable thermal performance and weather resistance. This window, made of 68 mm thick glued pine, offers excellent structural stability.

Performance and longevity

Two 4mm tempered glass panes are separated by a 16mm chamber (4+16+4) filled with argon gas, which insulates heat better than air. One pane has an ultra-thin Low-E coating to reflect heat and reduce heat loss. A silicone sealant helps keep the glass unit airtight and moisture-proof throughout its lifetime. GW-3 is therefore suitable for use in insulated garden buildings designed for year-round living.

Premium Accessories

The opening mechanism is delivered by MACO, a recognised European brand for metal products. The window opens inwards. A black metal sill protects the lower finish from rain splashes and ground moisture, while rubber sealing around the perimeter reduces air permeability. The spruce wood surrounds are factory-sealed with rubber, so no additional sealing is required on-site.

Compatible with DSHouse wooden houses

GW-3 is perfectly compatible with DSHouse wooden buildings. Spruce wood casings with rubber sealing help the window fit snugly into the log wall openings and reduce draughts. Windows can be delivered as part of a building kit or on their own.

Why ChoosePremium Wooden Window GW-3"?

Energy-Efficient Glazing

4+16+4 LowE ESG+Argon double glazing achieves a U-value of 1.1, which significantly reduces heat loss through the window. GW-3 is therefore suitable for use in insulated garden houses designed for year-round living.

MACO Hardware

GW-3 is equipped with a MACO tilt-and-turn mechanism: the window can open fully inwards for easy cleaning or tilt back at the top for controlled ventilation.

Durable Frame

The 68mm profile is made from glued pine. This ensures high dimensional stability and less risk of timber warping or cracking over time. The layered construction reduces timber movement due to seasonal changes in humidity, so the sealing remains reliable in the long term.

Precision Timber Assembly

GW-3 is particularly suitable for DSHouse garden houses. The spruce cladding provides visual continuity with the surrounding wooden walls, giving a professional look.
