Soft Coat Low 'E' Glass Benefits in Winter

Our double glazed sash window units are manufactured in a Soft Coat Low 'E' Glass as standard. Our 24mm double glazed sash windows will reflect heat back into your room during the Winter months off of the Low 'E' Glass.

Sash Windows Benefits during Summer Months

Traditional design Sash Windows provide excellent Ventilation during the Summer for your property. The design allows the Top Sash to be lowered and the Bottom Sash raised so that the gaps are equal at the Top and Bottom of your windows. This design ventilates your property by allowing fresh air to enter via the lower sash and warmer air to exit via the higher top sash, cooling and ventilating your rooms.
