Secondary Glazing
Secondary glazing enhances existing windows' thermal, acoustic, and security performance while preserving architectural integrity. Our bespoke solutions provide reversible adaptations suitable for listed buildings, reducing heat loss by up to 75% and noise pollution through tailored glass specifications. This sustainable retrofitting method extends building lifespan and improves occupant comfort.
Heritage Retrofitting
Specialised retrofitting for heritage and listed buildings maintains original window designs while introducing modern performance standards. Our approach complies with conservation regulations, achieving thermal improvements of 65-75% through low-E glass options and acoustic enhancements without altering protected architectural features.
Bespoke Design
Tailored glazing systems address unique architectural challenges, including curved, arched, and irregular window openings. Using laser mapping and CNC manufacturing, we create precision-fitted secondary glazing that complements diverse building styles while maintaining structural integrity and aesthetic continuity.
Professional Installation
Our dedicated installation teams ensure flawless execution with pre-installation surveys and quality control procedures. The process includes cavity optimization for noise reduction, precision fitting of recycled aluminium frames, and comprehensive post-installation checks to guarantee zero defects and optimal performance.
Sustainable Solutions
Eco-conscious retrofitting reduces embodied carbon by preserving existing windows while improving energy efficiency. Our systems feature 60% recycled aluminium, FSC-certified timber, and 35% recycled glass, with end-of-life recyclability exceeding 99% to support net-zero commitments and circular economy principles.
