Home > Companies > Selectaglaze Ltd > Series 15 Horizontal Sliding

Mid-range, horizontal sliding (HS) secondary glazing unit with robust but slender framing sections. Available with two, three or four sliding sash options. Designed to be removable to provide easy access to the outer window, facilitating cleaning and maintenance.

All fixings are concealed within the frame, which may be linked to other frames with a colour-matched mullion/ transom section.

Fitted with high performance brush seals that will almost eliminate drafts and ensure greater comfort near the window.

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


Blast tested to ISO 16933 Classification code EXV 33 (two pane only).
