Conservation Grade Double Glazing – Middle Knowle, Royal Tunbridge Wells

by

The Brief

Due to the windows fitted in listed buildings often being old or antique, heritage double glazing can be essential to prevent heat being lost through the windows, and money wasted when heating the property. This property in Tunbridge Wells required 178 new Conservation Grade Double Glazing Units (CDGU’s), which we manufactured and fitted along with 78 refurbished satin black metal window frames.

Getting to Work

With the scaffolding up, the team removed the opening elements of the metal casement windows and transported them to our workshop in Dorset. Each frame was carefully shot blasted and metal window repairs were applied to any rotten metal before a zinc rich primer and a satin black top coat was heat-baked on.

Templates were taken for each fixed existing leaded window to ensure an exact match and fit for the new conservation grade double glazing units. Stick on lead is applied to a 4mm clear float or conservation grade glass before being soldered and patinated to mimic a traditional leaded light. It is then sealed to a low-e clear pane of glass to meet modern heritage double glazing standards. Low-e glass is a coating applied to float glass for heritage double glazing as it reflects harmful rays of UV and infrared while retaining warmth within the room.

The Result

Each metal window frame and units of glass were then carefully refitted, retaining the characteristics of the period house. Aesthetically, it remains as breath-taking as before, but the conservation grade double glazing has preserved the home.
