Features Of Vertical Sliding Sash Windows

Authentic and beautifully crafted, it’s not just the looks of vertical sliding sash windows that are so appealing. Made from sustainable and fully recyclable materials, the A-rated Genesis windows we offer provide homeowners with significant savings on their energy bills as they come with superior thermal efficiency. Genesis complete their windows with high-quality safety features, including locks, hardware and reinforced frames. That’s why they’ve been accredited with the recognised security standard PAS 24. Despite being technologically advanced, they come with simple mechanisms that make them easy to open from the inside, allowing for a gentle breeze to enter the home as well as safe cleaning of the glass. Choose from 10 traditional colour combinations or 40 special foiled colours for the best results, and even opt for a different interior and exterior colour so that you can match your home’s decor too. All finishes are highly durable and won’t peel, fade or crack over time. Create the perfect finishing touch with the two jointing methods available; mechanical or seamless Graf welds. Mechanical joints will leave a result that’s exactly like a hand-crafted timber joint whereas the welded joints offer a seamless, precision-engineered corner.
