While double glazing may be the most popular option when it comes to glazing, there are some circumstances where single glazing is a natural choice. If you live in a Listed Property, or a Conservation Area it may be necessary to choose single-glazing to ensure you receive Listed Building Consent, or Planning Permission, for your sash or casement window renovation. Equally if you are replacing elements of a single glazed window you may wish to continue to use single glazing for consistency.

Although single glazing has a reputation for low energy efficiency and greater noise pollution, both factors can be improved during renovation. A well-fitted sash with the addition of Ventrolla’s Perimeter Sealing System, can make a significant difference. The addition of Secondary Glazing will add even greater defence against heat loss and noise from outside your home.
