uPVC Windows — Style, Comfort & Efficiency

Why uPVC Windows Are Ireland’s Most Popular Home Improvement

uPVC windows have become the most widely installed window type in Ireland over the past three decades, and the reasons are clear. Combining outstanding thermal performance, robust security, minimal maintenance requirements, and excellent value for money, uPVC windows represent a compelling upgrade over ageing single-glazed timber or aluminium frames that many Irish homes still have in place. At Northern Storm, we supply and install a comprehensive range of uPVC window styles to suit every home, every budget, and every architectural requirement.

Modern uPVC window profiles are a world away from the early generation of uPVC windows installed in Ireland in the 1980s and 1990s. Today’s profiles use multi-chamber construction, with up to six separate air chambers within the frame cross-section, each one acting as a thermal buffer that dramatically slows the transfer of heat through the frame. When combined with current-generation A-rated double glazing using low-emissivity glass and argon gas fill, the result is a window system that can reduce window-related heat loss by 70% or more compared to single glazing.

The security performance of modern uPVC windows has also improved enormously. Multi-point locking, which simultaneously engages multiple lock points around the window perimeter with a single handle operation, is standard across our entire range. Toughened, laminated, and even bullet-resistant glass options are available where maximum security is required. All our windows are manufactured and tested to the PAS 24 enhanced security standard.

One of the most appreciated attributes of uPVC windows is the minimal maintenance they require. Once installed, uPVC frames simply need an occasional wipe with a damp cloth to keep them looking pristine. There is no painting, no varnishing, no sealing, and no risk of rot or corrosion. The colour is integral to the material and will not peel or flake, and the frames are UV-stabilised to resist yellowing even in sunny, exposed locations.
