Our patented bubble gaskets are welded to the frame as part of the manufacturing process, meaning a continuous seal all the way round, eliminating draughts and providing resistance to water.

Security is always an important consideration so all our windows are internally glazed. High security locking systems are available on all our windows. The Espag handle allows you to open your windows slightly and fasten it, thus enabling air to circulate in.
All windows are available in the standard colours- white, mahogany, golden oak, cream and bog oak ( black) as well as off standard colours. If you like the idea of a different colour on the inside of your home, we can offer combinations such as black on the outside and white on the interior.
The variety is endless .... but the quality is consistent.
