Timber Windows
Our timber windows combine traditional craftsmanship with modern engineering to deliver exceptional thermal efficiency (U-values as low as 0.7 W/mK) and acoustic performance (up to 55dB). Sourced from sustainably managed forests with Full Chain of Custody certification, these windows feature multi-layer laminated construction for enhanced stability. Available in contemporary and conservation styles, they meet Code for Sustainable Homes Level 6 and Passivhaus standards while maintaining aesthetic appeal through micro-porous finishes that reduce maintenance requirements.
Alu-Clad Doors
Alu-clad external doors offer superior durability with aluminium cladding on timber cores, achieving U-values down to 0.8 W/mK. These doors incorporate Secured by Design certification, 30-60 minute fire ratings, and magnetic locking systems for enhanced security. The thermally broken design prevents heat loss while maintaining structural integrity, with optional triple glazing and decorative glass units. Suitable for both modern and heritage properties, they comply with Part L, M, and E building regulations.
Fire Rated Doors
Certified fire-resistant door sets provide 30 or 60 minutes of protection, combining safety with energy efficiency (U-values from 0.8 W/mK). Constructed with intumescent seals and fire-rated glass options, these doors meet BS 476-22 and European fire classification standards. Available in timber or alu-clad configurations, they integrate seamlessly with security systems and automated access solutions for commercial and residential applications while maintaining aesthetic consistency with other product ranges.
Bi-Fold Doors
Designer bi-fold door systems create seamless transitions between indoor and outdoor spaces, with slim profiles and high-performance thermal breaks. Available in oak or alu-clad finishes, these doors achieve U-values as low as 0.7 W/mK and incorporate multi-point locking systems for security. The track-guided mechanism allows smooth operation for large openings up to 6 metres wide, with weather-resistant thresholds and optional integrated blinds for enhanced functionality in residential and commercial settings.
Passivhaus Solutions
Tailored Passivhaus-compliant window and door systems achieve ultra-low U-values (0.7 W/mK) through triple glazing, warm-edge spacers, and thermally optimised frames. These components integrate with building fabric to meet rigorous energy efficiency standards, reducing heating demand by up to 90% compared to conventional construction. The solutions combine airtight seals, thermal bridge-free design, and advanced glazing technologies to maintain internal comfort while minimising environmental impact through sustainable material sourcing.
