Series 10 Slimline Horizontal Sliding 4 Pane

Slimline horizontal sliding (HS) secondary glazing unit with four sliding sashes. 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 draughts and ensure greater comfort near the window.

Features and benefits:

• Twin compression seals.
• Concealed fixings.
• Can be coupled to other units with colour-matched aluminium alloy transom/ mullion.
• Low profile running track.
