Patio Doors

About Our Patio Doors Service

Sliding patio doors offer a practical, space-efficient way to connect your home to the garden. Unlike French or bifold doors, patio doors operate by sliding one panel horizontally behind the other on a twin-track system — no floor space is lost to door swing. This makes them ideal for rooms where a hinged door would cause furniture placement problems, or where the internal layout is tighter. At Red Lion Windows, we supply and fit patio door systems in UPVC and aluminium. Both offer good thermal performance, with double-glazed sealed units and thermally broken frames keeping heat in and cold out. Sliding patio doors are also typically a more cost-effective solution than bifold systems for similar opening widths, making them a popular choice for homeowners who want a wide glazed rear opening without a premium specification. Security in a sliding door system is achieved through multi-point locking mechanisms and anti-lift pins that prevent the panels being lifted out of the track. All systems we supply meet current UK security standards, and higher-security cylinder options are available where required. Patio doors are well-suited to 1970s and 1980s housing stock — a period when many Lincolnshire homes across towns like Spalding, Holbeach, and Coningsby were built — where replacing an ageing sliding door or a dated timber screen with a modern, energy-efficient system makes an immediate improvement to both comfort and appearance.
