Why choose Fixed Window SFW-5?

Robust 45mm Spruce Frame

The SFW-5 features a 45mm solid spruce frame profile, offering structural rigidity and excellent dimensional stability. Spruce's natural properties make it well-suited to outdoor timber structures, resisting warping and maintaining a consistent fit over time.

4+6+4 ESG Double Glazing

The Enhanced Safety Glass (ESG) double-glazed unit with silicone sealant delivers reliable thermal performance and weather resistance. The glass construction reduces heat loss and minimises condensation, contributing to a more comfortable interior climate in the buildings it serves.

Rubber-Sealed Spruce Casing

Rubber sealants integrated into the spruce casing provide a durable, weather-tight perimeter seal. This detail reduces air infiltration and moisture ingress, extending the longevity of both the window unit and the surrounding timber structure.

Fixed-Pane Simplicity

As a fixed window, the SFW-5 eliminates moving parts and hardware complexity, making it a low-maintenance glazing solution. This design suits applications where light and aesthetics are priorities and ventilation is provided by other means.
