Traditional sliding sash windows were commonly made from timber and often needed regular maintenance. Modern uPVC sliding sash windows recreate a classic timber-inspired appearance while using low-maintenance, weather-resistant materials designed for everyday use and challenging Welsh weather conditions.
Nolan uPVC sliding sash windows are designed with energy efficiency in mind, using advanced glazing options and multi-chambered frames to help retain warmth. This construction can support a more comfortable indoor environment and help reduce heat loss, depending on the window specification and property.
Nolan sliding sash windows incorporate multi-point locking systems designed to help protect your home. These locks work alongside the window frame and sash to provide dependable everyday security, while the appropriate configuration can be discussed to suit your property’s requirements.
Sliding sash windows feature elegant proportions and slim sightlines that can help maximise the glazed area. The amount of daylight entering a room depends on its size, orientation and layout, but their design can help bring natural light into living spaces.
