The Ultion lock is fitted, as standard, on our PVCu Residential, French and Patio doors and also on our Magnum Range of Composite Doors.  We can also fit to your existing doors to give you the highest level of security for your home.

Thanks to 30 years of experience, Cathedral Windows knows what's required to create the highest quality door frames and fittings. Using a wide and quality range of materials, we can design and create PVCu doors that not only complement your property but don't break the bank either.
