Double Glazing

Robust Insulation and Security with Double Glazing

Efficient and secure double glazing installations by Sheerwater Glass

In double-glazing, two panes of glass are used with a gap between them, usually trapping moisture free air or an inert gas, therefore producing a second insulation barrier.

To make this more efficient, manufacturers add a drying agent to prevent moisture from being present between the two panes. It’s estimated that double glazing cuts household bills on average by around 11% per annum, often ensuring that the windows come to pay for themselves over a period of time.

Double glazing is noted for cutting out external noise and even for keeping noise inside the property, which makes it perfect for establishments such as pubs. Double glazed windows are noted for the enhanced security that they provide, due to the fact that they are harder to break into than a single glazed system. This makes them extremely useful for the ground floors of properties in particular.

Sheerwater Glass provides replacement double glazed units for homes and commercial undertakings. If you are looking for double glazing solutions then give our friendly team a call today on 01932 344415 and we’ll be happy to help or advise you on all aspects of double glazing, from manufacture to supply and installation.
