Period character. Modern comfort.

Period-style charm, A+ energy efficiency as standard and easy-clean PVCu, with acoustic glazing options.

01

The character your home deserves

Vertical sliding sashes, a neatly positioned meeting rail and optional sash horns capture the familiar look of period windows. Choose plain glass or a decorative bar pattern, then coordinate the colour and furniture. We’ll help preserve the proportions that make the house look right.

02

A+ warmth, with quieter-room options

ECOSlide’s standard specification combines insulating PVCu and double glazing for a BFRC A+ energy rating and a 1.3 W/m²K U-value. It helps reduce heat loss compared with older, less efficient windows. Where outside noise is a concern, ask us about a suitable acoustic glazing specification.

03

Clean windows without the timber upkeep

The sashes tilt inward to help you reach the outer glass for cleaning. PVCu needs no routine sanding or repainting, making it easier to maintain a clean, smart finish. The vertical sliding action gives you ventilation without a window projecting out over a path.

Plain or patterned glazing

Choose clear panes or a bar arrangement that follows the building’s original style.

White, colour and woodgrain

Coordinate the frame and furniture with the whole elevation; confirm the available finish combination.

Bays and feature openings

The individual windows and their joining details need to be designed together around the surveyed opening.

Before you choose

Is ECOSlide a REHAU TOTAL70 window?

No. Our ECOSlide vertical sash range is a separate system by Victorian Sliders. REHAU TOTAL70 is the system used for our PVCu casement and tilt-and-turn range.
