Secondary glazing

Secondary glazing offers an effective solution for enhancing thermal insulation in your home, especially during colder months. We provide custom-cut acrylic sheets specifically designed for secondary glazing, tailored to your exact measurements. Our plastic alternatives to traditional glass double glazing are both cost-effective and straightforward to install using either magnet bands or traditional nylon fasteners.

Clear windows: Provide transparency comparable to standard glass.
Opal windows: Offer a less transparent option that still allows natural light to enter.
Grey and brown double windows: Function similarly to glass with window film, effectively reducing direct sunlight.

We cut to your specifications, ensuring a perfect fit for your project.

Understand Secondary Glazing
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, which helps to retain heat indoors during colder periods and can contribute to lower heating costs. It also offers advantages in noise reduction, making your indoor environment more peaceful.


Why Choose Acrylic for Secondary Glazing
Acrylic sheets are a practical choice for secondary glazing due to their specific properties. Unlike traditional glass, acrylic is significantly lighter, which simplifies installation and reduces stress on existing window frames. It is also more shatter-resistant, providing an added layer of safety. While not as optically clear as glass, modern acrylic sheets offer good transparency suitable for most residential and commercial applications. Its insulating properties are highly effective for thermal regulation.


Installation Methods Explained
Installing secondary glazing with our acrylic sheets is designed to be a straightforward process for you. We offer two main installation methods to suit different needs and preferences. Magnet bands provide a flexible and easy-to-remove solution, ideal for windows that require regular access or seasonal installation. This method involves applying self-adhesive magnet and steel tapes to both the window frame and the acrylic sheet, allowing for a secure yet easily detachable fit. Alternatively, traditional nylon fasteners offer a more permanent and robust attachment, screwing the acrylic sheet directly into the window frame for a firm hold. Both methods ensure a tight seal to maximize insulation benefits.


Key Benefits of Secondary Glazing
Beyond energy saving, secondary glazing offers several tangible benefits. The added layer of acrylic and the air gap act as an effective barrier against heat transfer, reducing drafts and cold spots near windows. This leads to a more comfortable indoor temperature without excessive energy consumption. Furthermore, the additional pane significantly dampens external noise, which is particularly beneficial for properties located near busy roads or other sources of sound pollution. It is also a more cost-effective alternative to full double-glazing replacement, offering similar benefits at a fraction of the price and without extensive structural changes.


Types of Acrylic for Different Needs
We supply acrylic sheets for secondary glazing in various finishes to meet diverse functional and aesthetic requirements. Clear acrylic sheets provide maximum light transmission and a transparent view, much like standard glass, suitable for living areas or offices where an unoccupied outlook is desired. Opal acrylic offers a translucent finish, allowing light to enter while providing privacy or diffusing harsh sunlight, ideal for bathrooms or areas needing softened light. Our grey and brown tinted options function similarly to windows with built-in film, effectively reducing glare and heat from direct sun exposure, which can be useful for south-facing rooms or conservatories to manage interior temperatures and protect furnishings from fading.


Durability and Simple Maintenance
Our acrylic secondary glazing sheets are selected for their durability and long-term performance. Acrylic is resistant to many common impacts and environmental factors, ensuring it maintains its integrity over time. Cleaning these sheets is simple, requiring only a soft cloth and mild soapy water to remove dust and smudges, without the need for harsh chemicals that could damage the material. With proper care, your secondary glazing will continue to perform effectively for many years.
