Services
Heritage Windows
Our heritage windows replicate original Crittall designs for listed buildings and conservation areas. Using traditional SMW and W20 profiles, we ensure exact matches while integrating modern double glazing. This service preserves architectural integrity while meeting current thermal and acoustic regulations, ideal for historic properties requiring authentic restoration.
Fire Rated Windows
Fire-rated steel windows provide 30-60 minute protection using tested SMW, W20, and W40 systems. Compliant with BS476 standards, these units maintain integrity during fires through reinforced fixings and ceramic seals. Designed for commercial and residential buildings, they combine safety with transparency, approved by Warrington Fire Research.
Residential Windows
The W30 range offers FENSA-approved steel windows for homes, blending slim profiles with thermal efficiency. Suitable for modern and conservation areas, these units feature low-maintenance powder coatings and optional trickle vents. Ideal for homeowners seeking durable, aesthetically refined replacements with enhanced security.
Internal Screens
Custom internal steel screens and doors create open yet defined spaces using W20 profiles. Available with multi-point locks and safety glass, these designs meet building regulations while offering fire-rated options. Perfect for residential and commercial interiors requiring durable, stylish dividers with bespoke finishes.
Commercial Windows
Tailored steel window solutions for commercial projects, including new builds and renovations. Our systems provide vandal resistance, acoustic insulation, and thermal performance. With project-managed installations and CAD-designed specifications, we serve architects and contractors needing durable, code-compliant glazing for offices, schools, and public buildings.
