A Series 20 window will reduce heat loss by up to 50% using standard glass and up to 65% with a thermally efficient glass (low-E). High performance brush seals will almost eliminate drafts and ensure much greater comfort near the window.
The effectiveness of the insulation is measured by U-values, the lower the figure the better the insulation.

A Series 20 window set 100mm apart from the existing window will reduce noise levels by more than 40dB (decibels). In most circumstances this will achieve World Health Organisation guidelines for quiet living and working environments.

The Series 20 window fitted with simple catch locks and glazed with laminated glass will provide some resistance to forced entry but there is no test standard. When glazed with 6.8mm laminated glass it will also offer protection against blast to the same level as anti shatter film in conjunction with bomb blast net curtains.
