Security hinged casement (HC) secondary glazing suitable for use with very large windows and doors. Provides intruder resistance and blast mitigation.
Available as single and double side hung casements, allows full access to the outer window without mullions or transoms to impede the view. Can be glazed with thicker glass or sealed units and is certified to significant levels of security.
All fixings are concealed within the frame, which may be linked to other frames with a colour-matched mullion/ transom section.
Will reduce heat loss by up to 50% using standard glass and up to 65% with a thermally efficient glass (low emissivity). High performance compression seals will almost eliminate drafts and ensure greater comfort near the window.
