Profile: Omega Windows provides double glazing, doors, windows, fascia, conservatories and guttering. Our doors include French, composite, patio, PCV-U, interior and bi-fold doors. Secondary glazing reduces noise levels and draughts. The pre-painted, pre-drilled surround eliminates the need for timber batons and liners, and with no painting required, speeds up installation. It includes horizontal sliding units, hinged units, fixed units, lift out units, and vertical slider units.
