Vertical Slider

Synseal Windows


The new Evolve range uses PVCu over timber ensuring superior thermal retention properties, excellent weathering performance over time and very low maintenance for the end user, without losing the character of a sash window.

  • Robust locking devices guarantee high levels of security and the sash window balances maintain equilibrium at any point of travel when tilting.

  • The innovation doesn’t stop there however. Every vertical sliding window has been uniquely designed to be multi-tilt to aid maintenance and cleaning for the end user.

  • We can also offer the options of Astragal bar designs (face fix bar with back to back spacers), Georgian Bar designs (bar within the two panes of glass) and sash horns

  • Large window spans are easily covered by linking together window units, part of the original design innovation means spans of 1500mm wide x 2500mm high are completed with ease.
