Vertical sliding window close up


All sash windows from Double Glazing Essex Ltd come engineered in low maintenance uPVC frames capable of achieving an A-rating for energy efficiency. Each one delivers U-values that are impressively low, exceeding the minimum standard set in place by Building Regulations to keep living spaces well insulated and energy saving.

Vertical sliding window lock


Lifts, sash locks, and travel restrictors come fitted as standard on all our sash windows to keep households safe and protected without every disrupting the appearance established. Additional hardware can be integrated on requested, always finished in either a Chrome, White, or Gold finish for a seamless blend of looks and security.

Cream open vertical slider


Sash windows make light work of letting air into the home thanks to how effortlessly the vertical sash can be moved up or down. The sashes themselves even feature an inward opening tilt facility to allow easy and safe cleaning of the frame and glass from within the household. This is particularly useful for residents who live in high-rise apartments or multi-storey properties.
