Upgrade your home with super-insulated aluminium windows, built for lasting quality, security and fully customisable designs.
Your search for the perfect aluminium windows in Dublin starts here. We offer a striking variety of styles and colours to complement any home, from classic to contemporary.
Choose from popular finishes like True Black and Anthracite Grey, or opt for a dual-colour combination with white on the interior. For something more specific, any RAL colour can be matched to your exact requirements, an option available across the full colour range shown below. It takes a little longer, but the result is a window built around your home rather than off a shelf.
Full-height sashes swing open outward on hinges for an elegant look, maximum ventilation and unobstructed views.
Two sashes slide vertically past each other for a smooth transition between open and closed, giving ample ventilation with a classic sash profile.
A large glass pane maximises natural light for a bright, airy interior, with the flexibility to tilt for gentle ventilation or turn fully for a complete airing.

We lovingly craft our pieces by hand and only use the latest technology.
Every aluminium window we fit is finished to the same standard, regardless of size or style. Even when replacing an existing window rather than starting fresh, the details matter just as much: consistent powder coating, a properly tested lock and a frame built to hold its shape for decades.
Our aluminium frames use a 60-micron thick, fine textured powder coat finish. Beyond giving the frame a smooth feel, this texture also helps it resist dirt build-up, so windows stay looking sharp for longer with less cleaning required.
Security is treated with the same rigour. Every window uses secure locking cylinders tested to PAS 24, a specification set by the British Standards Institute to confirm a window can withstand attempts by opportunistic burglars, the same standard applied across our full window range.
Pairing triple glazing with Thermafill® technology creates a high-performance system that not only improves your home’s energy efficiency but also future-proofs it. Our triple glazing, offered as standard, delivers top-tier thermal efficiency using 44mm warm-edged triple-glazed units for the strongest performance available.
Upgrading to this system can improve your energy efficiency by up to 60% compared to double glazing, giving you more control over your thermostat, reducing condensation, and saving you money. With an expected lifespan of up to 30 years, you get to enjoy these benefits for decades, and the three panes of glass are also considerably tougher to break, adding extra security and reducing noise in your home.
With two pockets of gas or air between the panes instead of just one, triple glazing significantly reduces the heat loss or gain that comes with additional glass. This upgrade also brings added benefits, such as fewer cold spots and a more comfortable home overall.
