Security Doors


If it's ultra-secure doors that you require, we can help. Our high-security doors are designed to stand tall in the face of every kind of physical attack a burglar might throw at them. We can offer anti-bump, anti-snap, drill, pick, tamper, toque and force-resistant doors that will even withstand attempts at sawing, wrenching, corrosion or even burning it out. 

Why not take a look at our secure aluminium bi-fold doors today? Our Visofold aluminium folding doors can tranform your home whilst offering stunning panoramic views. Their aluminium profiles offer the highest standards of strenght and durability whilst requiring little maintenance and offering years of use. They are perfect for lounges, conservatories and even kitchen areas.

Also popular are our security PVCu bi-fold doors. These doors span large openings brilliantly and offer multi-facet door panels that fold back to allow the widest aperture of unrestricted access. The doors are stylish and effortless to operate. The doors can bring a stylish, contemporary feel to virtually any home.

Our PVCu residential doors are designed to withstand everything the British climates can throw at them and feature high-security hinges as well as steel reinforcing, whilst offering a wide range of moulded panel designs.
