Triple Glazing (Encapsulation) of Stained & Leaded Glass

Retain your Original Stained Glass Windows with Triple Glazing

Triple Glazing

Triple glazing follows the same principle as double glazing but allows for your stained glass window to be protected within a double glazed unit thus making it triple glazing.

To achieve triple glazing with stained and leaded glass, a stained glass panel is encapsulated inside a double glazed unit. The existing stained and leaded glass is removed from the existing window frame of your house, the old edge lead of the panel is removed and the panel is then re-sized. At the same time any cracked or broken pieces of glass are removed, replaced or repaired. After these preliminary steps are completed, a new specially profiled edge lead can be added.

Before encapsulating the window panel inside a double glazed unit, the stained glass is cleaned and the leads are polished. By encasing the stained glass window panel between two layers of toughened glass, a formidable barrier of triple glazing is created. This also helps the window panel retain heat effectively and efficiently while also resisting condensation. We use a thermally efficient glass as the inner leaf to further increase the amenity and heat retention properties of your home.

U - Values

All of the double glazed units that are used to encapsulate our stained glass window panels conform and comply with the UK Building Regulations (Part L).

Triple glazing via encapsulation is not only the perfect option for increasing the energy efficiency and security of your stained glass windows, it also adds value to your home.

The typical U-Values on windows is a measurement of heat loss and the rate at which it is lost.  U-Values indicate the overall performance in retaining heat and preventing it from escaping to the outside.  U-Values are measure in Watts per square metre Kelvin, or W/m2 K. In simple terms, the lower the U-Value number, the better the thermal performance of the window.

·      A Stained and leaded glass window has a U value of 5.6u.

·       A Conservation Double Glazed Unit (CDGU) has a U value of 2.0u

·      A Triple Glazed Unit (TGU) has a U value of 0.7u
