Glass
What is a Double Glazed Unit (DGU)?
Two panes of glass with space in between that is filled with air or inert gas. The unit has either an aluminium or thermal spacer separating the two panes and is sealed tight with sealants. The unit helps to create a thermally insulated window.

Reduce Heat Loss Further With Low Emissivity Glass
(Low-E)
​
Windows can reflect, take in, and transfer heat, so Low-E coatings can be used to enhance the performance of a window.
Low-E is a common abbreviation of “Low Emissivity”. Low Emissivity means a surface that gives off low levels of radiant heat. Therefore, a glass window with a Low-E coating will reduce the amount of heat transfer, making your house warmer in the winter and cooler in the summer.

​
U-values indicate the thermal conductivity of a material.
A U-value is the inverse of an R-value, so if heat transfer through a material is minimal, its U-value will be low and its R-value will be high.
​
U-values
​
The diagram below outlines how heat passing through glass reduces as you improve the specifications of the unit.
R-values
R-values indicate the thermal resistance through a material.
With R-values, the higher the value, the better the insulation and the better the thermal performance.
Table E.1.1.1, shown below from the new H1/AS1 is a quick and simple tool for understanding the performance of your frame material and glazing combination.
WHY COMFORTGLAZE?
• REDUCED ENERGY COSTS
Added insulation provides your home with a moderate temperature all year round, reducing the amount of energy needed.
​
• INCREASED VALUE
Your home is normally your biggest financial asset, COMFORTGLAZE high performance double glazing not only helps with comfort and energy efficiency, but it also increases the value of your home.
​
• WINTER WARMTH
High Performance Double Glazing keeps the cold out and traps the warmth in, allowing for a warmer, drier and healthier home.
​
• CONDENSATION
You will benefit from reduced condensation on the insides of your windows. Your home will stay drier and healthier.
​
• NOISE
You'll notice a great reduction in outside noise, busy road noise or noisy neighbours can be a thing of the past.
​
• FADING & PRIVACY
Standard tinted or laminated double glazing reduces UV rays by up to 99%.
​
• COOLER IN SUMMER
Reduces excessive summer heat gain allowing for a more moderated internal climate all year round.
