Fixed Spruce Window with Double Glazing for Timber Buildings

The SFW-6 is a fixed timber window for wooden garden buildings, log cabins, and timber structures. Constructed from a 45mm spruce profile, it delivers structural rigidity and a natural aesthetic consistent with high-quality timber construction.

Double-Glazed Performance in a Timber Frame

The SFW-6 features a 4+6+4mm double-glazed unit sealed with silicone sealant, providing reliable weather resistance and improved thermal performance compared to single-glazed alternatives. The spruce casing is fitted with rubber sealants to ensure a tight, draught-resistant installation.

As a fixed window, the SFW-6 is optimised for applications where ventilation is provided by other means — such as doors or openable windows — making it an efficient and cost-effective choice for maximising natural light in garden offices, summerhouses, and storage buildings.

Why choose Fixed Window SFW-6?

Robust 45mm Spruce Profile

Made from 45mm spruce, providing a solid, stable profile that integrates seamlessly with standard timber wall constructions. The natural density of spruce ensures long-term dimensional stability and resistance to warping.

Double-Glazed Weather Resistance

A 4+6+4mm double-glazed unit sealed with silicone sealant delivers reliable protection against wind-driven rain and temperature fluctuations. This glazing configuration improves thermal performance compared to single glazing.

Rubber-Sealed Spruce Casing

The window casing is crafted from spruce and fitted with rubber sealants to create a draught-resistant perimeter seal. This ensures the window performs reliably over time without requiring frequent maintenance adjustments.

Fixed Design for Maximum Light

As a non-opening fixed window, the SFW-6 is optimised for applications where maximising natural light is the priority. Its clean, uninterrupted glazed face provides an unobstructed view and a modern appearance suited to contemporary timber structures.
