Our vertical sliders are the perfect solution for homeowners who want to enjoy the benefits of modern secondary glazing without losing the unique character of their existing sash windows. Ideal for period homes, listed buildings and traditional properties in Northern Ireland, Belfast and Dublin, a vertical slider window provides warmth, noise reduction and security, all while preserving your property’s façade.
If you are considering replacing your sash windows with double or triple glazing, choosing a vertical slider window installation is often the more practical and cost-effective alternative. With sleek aluminium secondary glazing frames and discreet finishes, our units blend seamlessly into your interiors while delivering outstanding performance.
Slide Pass Capability
For additional access, our vertical sliders can be manufactured with slide pass functionality. This allows both panels to slide completely past one another, ensuring the entire secondary unit can be accessed with ease for ventilation and cleaning.
Tilt-in Capability
For ultimate flexibility, our vertical slider windows can also be designed with a tilt-in feature. This enables each panel to pivot individually up to 180° inwards, providing unrestricted access to the external window. The tilt-in variation is supplied with restrictor arms as standard, ensuring smooth and safe operation.
