Our sash windows upvc we offer are outfitted with a range of hardware. The hardware we chose to use was carefully chosen for its aesthetics, strength, and user-friendly experience.

Double Glazing:

Our sash windows feature effective double glazing of 24mm as normal. Double glazing comprises two glass panes that are separated by a gap that is filled with gas that is insulating argon gas. This makes it much more efficient in reducing the transfer of heat, making interiors more comfortable during winter and cooler during summer.

All of our sash windows come with Low E glass. This assists in controlling the flow of heat across the glass, ensuring that interiors stay cooler in summer and warmer during winter.
