The Highest Performing Secondary Glazing Solution
For customers looking for the highest levels of insulation and sound reduction, heavy duty secondary glazing offers one of the most effective solutions available. Manufactured using premium double glazed units and bespoke frames, every installation is tailored to maximise both thermal efficiency and acoustic performance.
Unlike replacing your existing windows, heavy duty secondary glazing retains the original appearance of your property whilst delivering many of the benefits associated with modern double glazing. It’s a popular choice for listed buildings, conservation areas and premium residential properties where performance and aesthetics are equally important.
Why Choose Heavy Duty Secondary Glazing?
Heavy duty secondary glazing is designed for properties where standard secondary glazing may not provide the required level of thermal or acoustic performance. By incorporating a sealed double glazed unit within a robust secondary frame, it creates an additional insulating barrier that helps reduce heat loss, minimise external noise and control condensation more effectively.
Whether you’re located near a busy road, railway line or airport, or simply want to improve the comfort and energy efficiency of your property, heavy duty secondary glazing delivers outstanding performance without replacing your existing windows. Every system is manufactured to measure, ensuring a precise fit that preserves the appearance of your property whilst providing long-term benefits.
