Secondary glazing

How secondary glazing works
Secondary glazing involves adding an extra pane of material, typically acrylic, to the inside of an existing window frame. This creates an insulating air gap between the original window and the new pane. The primary function is to improve thermal insulation, retaining heat indoors during colder periods and helping to lower heating costs. Secondary glazing panels also help reduce external noise for a quieter indoor environment.

Why choose acrylic secondary glazing
Acrylic secondary glazing sheets are a practical choice due to their lightweight and durable properties. Unlike traditional glass, acrylic is significantly lighter, simplifying installation and reducing stress on existing window frames. It is also shatter-resistant, providing an added layer of safety. Modern acrylic sheets offer good transparency suitable for both residential and commercial applications while delivering effective thermal insulation.

Installation options for diy secondary glazing
Installing diy secondary glazing with our sheets is straightforward. We offer two main installation methods to suit different requirements. Magnetic secondary glazing using self-adhesive magnetic and steel tape provides a flexible, easy-to-remove solution that is ideal for windows requiring regular access or seasonal removal. Alternatively, traditional nylon fasteners offer a permanent attachment by fixing the secondary glazing sheets directly into the window frame. Both methods create a tight seal to maximise insulation benefits.

Key benefits of secondary glazing panels
Beyond energy savings, secondary glazing offers clear practical benefits. The added layer and insulating air gap act as a barrier against heat transfer, reducing draughts and cold spots near windows. This maintains a comfortable indoor temperature without excessive energy use. Furthermore, secondary glazing panels significantly dampen external noise, which is particularly useful for properties near busy roads. It is a cost-effective alternative to full double glazing replacement, delivering similar performance without structural alterations.

Material choices including polycarbonate secondary glazing
We supply secondary glazing sheets in various materials and finishes to meet functional and aesthetic needs. Clear acrylic sheets provide maximum light transmission similar to standard glass, ideal for living spaces and offices. Where extreme impact resistance is required, polycarbonate secondary glazing offers a virtually unbreakable alternative. Opal acrylic provides a translucent finish that diffuses harsh sunlight and adds privacy, while grey and brown tinted sheets reduce solar glare and heat in south-facing rooms and conservatories.

Durability and simple maintenance
Our acrylic and plastic secondary glazing sheets are selected for long-term durability. The material resists common impacts and environmental wear, maintaining its clarity over time. Cleaning these sheets requires only a soft cloth and mild soapy water to remove dust and smudges, avoiding harsh chemicals that could mark the surface. With basic care, your secondary glazing will perform effectively for years.

Cut to size secondary glazing solutions
Every window has unique dimensions, which is why we provide cut to size secondary glazing tailored to your measurements. Accurate sizing is essential for maximising thermal insulation and ensuring a neat finish. Simply supply your dimensions, and we will prepare your secondary glazing panels to size, making installation quick and efficient.
