WHY CHOOSE DOUBLE GLAZING?
∙ Reduced energy costs
∙ Warmer in winter
∙ Cooler in summer
∙ Reduce sound
∙ Enhanced security
WHAT IS THE U-VALUE?
A U-value is a measure of heat loss in a building element such as a window. The higher the U-value is the worse the thermal performance. A low U-value usually indicates high levels of insulation.
U-values in double-glazing will vary depending on: the width of the gap between the two panes of glass, whether gas or air is used to fill the gap, and the combination of glass used.
Industry standard for double-glazing is 3.0. Thiering and Partner is able to build units with a U-value of 1.1 for double-glazing and 0.9 for triple-glazing. Single-glazed windows generally have a U-value of 5.8.
HOW ARE THE TWO PANES SEALED TOGETHER?
With spacer bars to hold them apart and desiccant within the hollow spacer bar to prevent condensation, then heat-sealed.
HOW DOES DOUBLE-GLAZING IMPROVE SOUND REDUCTION?
Sound vibration varies with different types of glass; because two types of glass vibrate at different frequencies, sound passes across them with more difficulty.
Thiering and Partner can reduce sound transfer by up to 60% depending on the frames and combination of glass used.
HOW DOES DOUBLE-GLAZING ENHANCE SECURITY?
Similarly the security benefit of the additional pane of glass can be enhanced with the use of certain types and combinations of glass.
