Traditional Casement Windows
BJM’s traditional casement windows combine the best of both worlds – all the advantages of a high-quality modern window in a package that recreates traditional aesthetics. A popular choice among planners and conservationists, these windows use state-of-the-art technology and materials while retaining an old-world charm that makes them perfect for applications where conservation is an issue.
Timber
Grade 1 Scandinavian Redwood taken from sustainable sources. Complies with BS EN 942: 1996.
Preservative
Every component of every window is preserved before assembly and paint application.
Adhesives
We use high-quality adhesives providing excellent strength, durability and water resistance, and which comply with BS EN 204 D4.
Weather seal
All our traditional casement windows are supplied with weather seals as standard. Seals are paintable and guaranteed against shrinkage if applied and maintained as recommended.
Ironmongery
Ironmongery generally complies with BS6462: 1994.
Our openers are generally hung using superior-quality butt hinges. Standard windows are supplied with facemounted fasteners and casement stays, though we offer a range of alternative locking mechanisms including espag or shootbolt locking.
Fasteners, casement stays and other handles are available in a wide range of finishes.
Ventilation
All windows can feature flush-fitting ventilators for constant airflow.
Factory finish option
Windows can be paint finished to any RAL or BS number/reference and supplied factory glazed. Windows are finished using a waterborne high-build coating system.
Windows are glazed using Double Glazed Units manufactured and tested to BS EN 1279, and comply with Part L of Building Regulations for improved thermal insulation.
For increased lifespan, factory glazed units are installed using a drained and vented method to BS6375 part 1989.
