Slim Line Triple Glazed Windows and Doors

Modern architecture is all about light, space and clean lines. Homeowners and architects are increasingly choosing slim line sliding door systems and ultra-slim window systems to create bright, open living spaces with minimal visual interruption.

At Glass Worx Ltd, we specialise in high-performance, triple glazed architectural glazing and we offer a range of slim line systems that are becoming increasingly popular in both new builds and retrofit projects.

Here’s why.
