A discreet solution to draughty or noisy environments, particularly where listed status forbids modern replacement windows.
Our vertical sliding secondary glazing is designed especially for traditional sash windows. It mirrors the primary sash window and consists of two secondary sashes, one above the other, securely retained in its own outer frame. The vertical sliders are supported by robust spiral spring balances for added ease of opening & closing. The spiral balance system supports the weight of the secondary sashes & makes these units suitable for larger sash windows.
A tilt-In facility which allows each secondary sash to be independently released from the outer frame & pivoted inwards through almost 180°, makes it cleaning quick and easy.
Suitable for Listed Building sash windows, Conservation Areas & all other properties with sash windows.
