Warmer, Quieter and More Secure Homes and Commercial Properties Across Dublin
Secondary Glazing NI provides expert secondary glazing installation throughout Dublin, serving homeowners, landlords, architects, and contractors across the city and surrounding areas. Whether you are based in the city centre or the suburbs, our team delivers bespoke, high-performance secondary glazing solutions tailored to your property.
Dublin properties face a unique set of challenges. Busy roads, dense housing, older building stock, and a significant number of period and protected structures all create demand for a window solution that improves comfort without compromising the character of a building.
Secondary glazing is the ideal answer. By installing a slim, discreet internal aluminium frame directly behind your existing windows, we create a highly effective secondary barrier that dramatically improves thermal insulation, noise reduction, and security, all without touching the original window.
We are professionals and take pride in our craft. Our customer success stories reflect this.
Our products are cost competitively priced and with our ability to offer installation we can streamline the process.
We strive for customer satisfaction and always aim to offer a service of value.
Dublin is a busy, vibrant city, and for many residents that means unwanted noise from traffic, neighbours, and street activity. Secondary glazing with acoustic glass significantly reduces the amount of external sound that enters your home, creating a noticeably quieter and more peaceful living environment. This is one of the most common reasons Dublin customers contact us, as demonstrated by our completed project in central Dublin, where a homeowner with four sash windows reported a dramatic improvement in both sound and heat insulation after installation.
Older Dublin properties, including Victorian terraces, Georgian townhouses, and mid-century homes, were typically built with single-glazed windows that offer little insulation. Secondary glazing adds a second layer of glass with an air gap that acts as an insulating buffer, keeping warmth in and cold draughts out. Customers regularly report a noticeable reduction in heating costs following installation.
Dublin has a rich architectural heritage, with large numbers of protected structures and conservation areas throughout the city. Many of these properties cannot have their original windows replaced under planning conditions. Secondary glazing is one of the few window upgrades that satisfies these restrictions, as it is fitted entirely on the inside and leaves the external appearance completely unchanged. We have extensive experience working on heritage and listed buildings, and we understand the sensitivity required for this type of project.
Additional glazed units add a further physical barrier to your windows, making forced entry more difficult. Our units are fitted with lockable mechanisms as standard, providing enhanced security without any external modification to your property.
We supply and install the full range of secondary glazing unit types across Dublin, including:
Vertical Slider – Designed to replicate the operation of traditional sash windows, making these ideal for period Dublin properties where timber sash windows are a defining feature.
Horizontal Slider – A sleek, modern option with minimal sight lines, suited to a wide range of property styles.
Hinged Units – Provide easy access to the exterior window for cleaning and ventilation.
Lift Out Units – A practical solution for windows that require only occasional access.
All units are manufactured to measure and fitted by our trained installation team, ensuring a precise fit and a clean, professional finish.
