Tall Double-Glazed Fixed Spruce Window

The SFW-7 is a fixed glazed window unit for timber garden structures, log cabins, and wooden outbuildings. With a 45mm spruce profile and double-glazed 4+6+4 ESG glass, this window delivers clear sightlines, natural light, and reliable weather performance without the added complexity of an opening mechanism.

Engineered for Lasting Performance in Timber Buildings

All wooden parts exceeding 160cm in length are manufactured from laminated spruce — a deliberate engineering choice that prevents warping over time while preserving the aesthetic of solid, natural timber. The result is a window that looks premium and performs consistently throughout the seasons.

The spruce casing is fitted with rubber sealants to create a weather-tight perimeter, while silicone sealant bonds the double-glazed unit securely within the frame. This combination ensures the window remains airtight, moisture-resistant, and structurally sound under typical European conditions.

At 571mm wide and 1821mm tall, the SFW-7 offers a tall, narrow format well suited to side elevations, gable ends, or positions where vertical light is preferred. Its clean, natural spruce finish integrates seamlessly with both traditional log cabin aesthetics and contemporary timber frame designs.

Delivered as part of Dadsons’ compatible window and door range, the SFW-7 is available to B2B partners as an add-on component for standard or bespoke timber building configurations. Contact us to discuss volume requirements and integration with your current product range.

Why choose Fixed Window SFW-7?

Warp-Resistant Laminated Spruce Frame

All wooden components exceeding 160cm are manufactured from laminated spruce rather than solid timber. This prevents the warping and twisting that commonly occurs in long-span natural wood, ensuring the window retains its shape and weather seal over years of use — while maintaining the visual character of solid timber.

Double-Glazed ESG Safety Glass

The 4+6+4 ESG double-glazed unit is bonded with silicone sealant for a secure, weatherproof fit. Toughened ESG glass offers improved safety in the event of breakage.

Rubber-Sealed Spruce Casing

The perimeter casing is machined from spruce and fitted with rubber sealants, creating a tight, moisture-resistant interface between the window frame and the surrounding wall structure. This reduces the risk of air infiltration and condensation ingress at the casing joint.

Fixed

As a fixed, non-opening window, the SFW-7 eliminates hinges, handles, and moving parts — reducing maintenance requirements and long-term failure points. It is an ideal choice for applications where natural light and visual connection to the garden are priorities, but ventilation is managed through other openings.

Frequently Asked Questions

The SFW-7 is a fixed window — it does not open. This makes it ideal for positions where light is the primary requirement and ventilation is provided through other windows or doors within the structure. The fixed design also eliminates mechanical components, reducing long-term maintenance.

The SFW-7 uses a double-glazed 4+6+4 ESG (toughened safety glass), sealed with silicone sealant. ESG glass is designed to break into small, blunt fragments rather than sharp shards, which is an important safety consideration.

This engineering decision prevents the natural warping and cupping that can occur in long solid-wood components over time, particularly in environments with variable humidity. The laminated construction maintains the solid wood aesthetic while delivering superior dimensional stability.

The SFW-7 measures 571mm in width and 1821mm in height.

The SFW-7 features a 45mm frame profile. Compatibility with specific wall log thicknesses should be confirmed at time of order.
