Secondary Glazing
Our secondary glazing systems provide exceptional sound insulation for homes and commercial properties. Using advanced acoustic glass technology, these custom-fitted solutions retain heat while reducing exterior noise by up to 80%. Available in multiple configurations including vertical sliders, hinged panels, and bespoke shapes, our systems maintain thermal efficiency without compromising aesthetics. Customers benefit from 40 years of manufacturing experience and nationwide installation services.
Bi-fold Doors
The Aluna bi-fold system offers sleek, space-saving entrance solutions with security rated to PAS24 standards. These precision-engineered doors feature adjustable jambs and universal lock keeps for easy installation. Available in square or textured profiles with dual-tone colour options, they achieve U-values as low as 1.4 W/mK. Optional low thresholds enhance accessibility while maintaining weather protection for modern residential and commercial properties.
Patio Doors
Aluna hybrid sliding patio doors combine slim 25mm interlocks with large 2.5m x 2.7m sash sizes for uninterrupted views. Our thermally efficient systems use double or triple glazing with U-values down to 1.4 W/mK. Available in any RAL colour, these doors feature multi-point locking systems and optional trickle vents. Durable aluminium cills direct water away while maintaining aesthetic continuity with exterior designs.
Entrance Doors
The Aluna entrance door range includes Primo and Cielo models with thermal insulation down to 0.68 W/mK. These secure doors incorporate multi-point hook locking systems and reinforced hinges meeting PAS24 standards.

Available in ten contemporary colour combinations with optional fingerprint access upgrades.

Engineered for durability with precision joints and weatherproof seals, they provide maximum light transmission while maintaining energy efficiency in both new builds and renovation projects.
