Secondary Glazing NI

Enjoy a Quieter Environment

Many homeowners upgrade to modern PVC double glazing for comfort and energy savings, but if you live near busy roads, railways, or airports, noise can still intrude. Secondary glazing offers a highly effective solution.

By creating an air gap between your existing window and the secondary unit, it forms a robust sound barrier, delivering superior noise reduction—cutting noise levels by up to 80%. Our systems use advanced technology for a precise fit, enhancing acoustic performance, thermal efficiency, and security, all while preserving your window’s appearance.

Stay Warmer

Up to 10% of household heat escapes through windows. Secondary glazing adds an extra layer of protection. A 150mm–200mm cavity acts as an insulator, reducing heat loss by up to 65% when paired with the right glass.

We typically recommend hard-coat Low-E glass, which reflects warmth back into the room, lowers energy usage, and helps reduce heating bills.

Strengthen Home Security

Windows are common weak points for break-ins. Secondary glazing provides an affordable, discreet, and effective security upgrade. Its strong aluminium frames, laminated or safety glass, and internal locks create a tough secondary barrier.

This added layer makes it significantly harder for intruders to gain access, giving you greater peace of mind

A Vertical Slider is a type of window or glazing unit designed to slide open and closed along a vertical axis. It consists of two or more sashes (movable panels) that can slide up and down within the frame.

This design is often used in traditional or period-style properties but is also popular in modern buildings for its functionality and aesthetic appeal.

A Horizontal Slider is a type of window or glazing unit where one or more sashes slide horizontally along a track within the frame.

This design offers a sleek, modern look and is highly functional, providing ease of use and space-saving benefits.

A Hinged Unit refers to a type of window, door, or glazing system that operates on hinges, allowing it to open and close by swinging inward, outward, or in both directions, depending on its design.

Hinged units are one of the most traditional and versatile options for access and ventilation.

Lift-Out Units are a type of secondary glazing system designed to provide additional insulation, soundproofing, and energy efficiency for windows.

These units consist of a removable glazed panel that can be lifted in and out of the frame for ease of access, cleaning, or maintenance.
