Crystal's inline patio doors allow natural light to flood into a property through large glazed sashes. The full width thermal core at the heart of the range gives the desirability and durability of aluminium, while keeping the home snug and warm. Custom designed 10 wheel rollers glide effortlessly on a precision engineered track, making these panoramic doors the perfect blend of aesthetics and performance.
Every patio is independently certified to PAS24:2016, the benchmark in enhanced security performance requirements for doorsets and windows in the UK. Each door is also fitted with a high security ‘Anti-Snap’ and ‘Anti-Bump’ Yale Platinum 3 Star cylinder, designed to provide maximum security against known cylinder attack methods.
