Services
Secondary Glazing
Secondary glazing adds an extra window pane against existing windows, preventing draughts and reducing external noise by up to 90%. Ideal for residential properties, it enhances thermal efficiency, lowers heating costs, and preserves original window designs. Our custom solutions ensure seamless integration and long-term durability.
Thermal Insulation
Our thermal insulation windows improve energy efficiency by up to 60%, minimising heat loss and condensation. Designed for listed buildings and conservation areas, these solutions maintain architectural integrity while reducing energy bills. Low-E glass options reflect heat indoors during winter and block solar radiation in summer.
Soundproofing
Soundproofing windows reduce noise pollution from traffic, aircraft, or neighbours by up to 90%. Using SGG STADIP SILENCE laminated glass, our secondary glazing creates peaceful interiors without altering existing windows. Ideal for urban properties, it also enhances security and UV protection.
Listed Buildings
We specialise in secondary glazing for listed buildings, ensuring compliance with conservation regulations while improving thermal and acoustic performance. Our discreet, custom-fitted solutions match original designs, avoiding intrusive modifications. We collaborate with local councils to facilitate planning approvals and listed building consents.
Vertical Sliders
Vertical slider secondary glazing replicates traditional sash window designs, maintaining aesthetic continuity in heritage properties. These units feature counterbalanced mechanisms for smooth operation and can be fitted with tilt-to-clean options for oversized windows. Slim profiles ensure minimal visual impact while enhancing insulation and noise reduction.
