  • Warmer A Series 55 window will reduce heat loss by up to 50% using standard glass and up to 65% with a thermally efficient glass (low-E). A high performance brush seal and perimeter mastic 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.

    Quieter A Series 55 window set 100mm apart from the existing window reduces noise levels by 45dB (decibels) with higher figures achieved using thicker glass. This can achieve World Health Organisation guidelines for quiet living and working environments even in quite challenging noise environments.

     Safer The Series 55 Demountable Fixed window has considerable inbuilt strengths. Manual attack tests have been conducted by the Loss Prevention Certification Board using a range of tools to attack both frame and glass over defined periods of time. Resistance against the effects of explosives has been assessed on a specialist Blast Range using a simulated car bomb and it has also undergone ballistic test.
