The project

The overall window replacement project included the following:

The new traditional spring sash windows installed were matched with the original style and proportions, shape, glazing bar size and placement, overall glazing patterns, opening methods and materials and finishes.

All ground floor and easily accessible sash windows and doors were supplied as PAS 24: 2016 certified.

To meet energy efficiency standards, it was ensured that all replacement windows had a U-value of 1.4 calculated by the standards of EN ISO 10077-1:2006. The lower the U-value the lower the energy loss (typically, new sash windows should achieve a U-value of 1.6 W/m2⋅K or lower).

Lastly, ventilation was provided via controllable Titon XS16 4600EA trickle ventilators, dependent on the width of the frame.
