45mm Spruce Casement Window with Double Glazing

The SW-3 is a solid timber casement window manufactured from 45mm spruce profile, designed to complement log cabins, garden houses, garages, and other outdoor structures. Built for durability and weather resistance, it combines traditional craftsmanship with practical, installer-friendly features.

Engineered for Weather Resistance and Long-Term Performance

The SW-3 features double glazing in a 4+6+4 configuration, sealed with silicone sealant to prevent moisture ingress and improve thermal performance. Rubber draught excluders on all sides provide a tight seal against wind and water penetration, making this window suitable for year-round installations in variable climates.

The top-hung opening mechanism is fully adjustable via an allen key, allowing fine-tuning of hinge tension on-site without specialist tools. Hinges are supplied with decorative black covers for a clean, finished appearance. A black high-quality handle and a spruce casing with rubber sealants complete the unit, ensuring it is ready for installation.

Why choose Single Window SW-3?

Double Glazing for Thermal Comfort

The 4+6+4 double-glazed unit, sealed with silicone sealant, reduces heat loss and minimises condensation. This makes the SW-3 suitable for garden buildings intended for regular or extended seasonal use.

Precision-Adjustable Hinges

Top-hung hinges can be fully adjusted on-site using a standard allen key, allowing contractors to achieve a perfect, draught-free fit without specialist tooling. Decorative black hinge covers deliver a clean finish once installation is complete.

All-Weather Sealing System

Rubber draught excluders on all sides, combined with a rubber-sealed spruce casing, provide protection against wind and water ingress.

Ready-to-Install

Supplied as a complete, pre-assembled unit with handle, hinges, glazing, and casing included. No additional components are required.

Frequently Asked Questions

The SW-3 is manufactured from spruce wood with a 45mm profile. Spruce is selected for its dimensional stability, workability, and natural compatibility with the Dadsons timber building range.
