Rehau vertical sliders are often the choice of specifiers, fabricated to strict quality control standards with the best gearing and hardware possible. The key point of a sash window and its operation are the balances, which carry the weight of the sashes, at 1st Class we only use a reliable and heavy duty hardware for peace of mind and long lasting operation.

Unlike traditional sash windows, our products feature woolpile draft excluder’s and covers to ensure that there is a tight seal when the sashes are closed. They also feature tilt restrictors that enable the sashes to tilt into the room for cleaning.

Classic-style hardware and fittings and optional decorative horns replicate the traditional timber sash window to create a stunning finish. An optional deep bottom rail and optional georgian or astragal bars add to a simply superior uPVC sash window.

The Rehau Heritage system has been developed following extensive consultation with conservation bodies and as a result sliding sash windows manufactured from the system are the most distinctive and authentic-looking sash window available on the UK market.
