Superior Energy Efficient Double Glazing – bi-Eco

County Windows bi-Eco double glazing units are specifically manufactured to be a preferred alternative to triple glazing providing the high thermal efficiency with out the extra cost.

The higher cost of Triple Glazing  is a result of additional frame material and glass that also increases the weight, which is a factor during installation.

With bi-Eco windows you can achieve the kind of U values or thermal efficiency that is typically met by triple glazing, without the extra cost.

Opting for superior double glazing means you won’t have any of the drawbacks that you may encounter with triple glazing, such as impaired visibility and reduced light from having 3 panes.
