Home > Companies > Selectaglaze Ltd > Series 10 Horizontal Sliding

Slimline horizontal sliding (HS) secondary glazing unit, available with two, three or four sliding sash options. Removable to provide easy access to the outer window, facilitating cleaning and maintenance.

Sashes have integral full height finger pulls, 23 mm wide interlock stile and twin silicone treated, grey polypropylene pile weatherseals. All fixings are concealed within the frame, which may be linked to other frames with a colour-matched mullion/ transom section.

Suitable for listed buildings where the primary glazing cannot be changed. It is a reversible adaptation, so generally accepted by heritage agencies.

Will reduce heat loss by up to 50% using standard glass and up to 65% with a thermally efficient glass (low emissivity). High performance brush seals will almost eliminate drafts and ensure greater comfort near the window.

Thermal performance:

U-values as low as 1.8 W/m²K (timber primary window and low-E glass in secondary glazing).
