As with the majority of materials and techniques, there has been a vast improvement in glazing products for our industry. Traditionally, windows and doors were glazed with a single pane of glass, sealed with linseed oil putty. This method provided very poor heat efficiency, condensation issues and a lack in safety.
With demand always increasing for homes to become more economical, glass plays a vital part in a door or windows overall thermal value. The glass we use as standard in our products is a high performance 24mm – 28mm thick, double glazed unit which is low-emissivity (otherwise know as low-e glass).
Basically, low-e glass is a type of energy efficient glass designed to prevent heat escaping through your windows to the cold outdoors. The way is works is thanks to an invisible coating that acts as a poor radiator of heat and does not allow heat to be transferred to the outside. Instead, the low-e coating actually reflects the heat back into your room, keeping your home warmer and your bills lower!
In times that a modern double glazed unit is unacceptable for a project such as, heritage work or in some listed buildings, we are able to source a vast variety of alternatives to meet project requirements through our local supplier.
A question that we frequently get asked regarding glazing bars, is why we use applied bars (glazing bars that are stuck onto the internal and external faces of the glass). The answer is really very simple when you begin to understand the evolution of glazing.
