How we approach it
Rationel, Velfac and Internorm windows are high quality timber and aluminium composite systems that use their own hardware and glazing methods, which many general glaziers will not work on. Repairs to all three are listed among MK's services: glass replacement, hinge and locking gear repairs, and adjustments.
