Why use DAG Inter as your Double Glazed Units Supplier?

At DAG Inter Ltd we can manufacture and install Double Glazed Units to comply with British safety standards.


We supply and install double glazed units as windows, doors and conservatories in UPVC, Timber and Aluminium to residential and commercial properties in the London & Kent area. Not only that, DAG Inter specialise in Secondary Double Glazing, Composite Doors and Glass Bi-Folding Doors.

We can also combine other glass technologies such as coloured glass, tint glass, mesh laminated glass, decorative glass interlayers and back painted glass into our double-glazed units.

We have endless options to make a double glazed unit not only a safety factor but a decorative feature of the building or glass flooring.

Our double glazed units are manufactured exclusively using float or safety glass and dehydrated air; a gas that improves the thermal insulation, is enclosed between two sheets of glass. The process is based on the latest dual seal technology and ensures that the double-glazed unit is hermetically sealed.

The two sheets of glass are separated by an aluminium or glass spacer bar or a thermally insulating material. They are sealed around the perimeter using organic seals and the spacer bar is filled with desiccant to dry air in the cavity.
