  • Warmer

    A Series 41 single hinged window will reduce heat loss by up to 50% using standard glass and up to 65% with a thermally efficient glass (low-E).  Further improvements are possible using sealed glass units that create triple glazing. High performance compression 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 41 single hinged window set 100mm apart from the existing window will reduce 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 and the twin compression seals remain very effective over long periods.

     Safer

    The Series 41 window fitted with a concealed and secure multi-point locking system is a Police preferred specification under the Secured by Design initiative. Higher levels of intruder protection are achieved by using thicker anti-bandit laminate glass. These specifications will also provide more significant levels of blast protection.
