Glass performance and durability requirements are very demanding in sunrooms. Super Sealed insulating glass is manufactured using a unique dual seal technology that ensures the longest seal life of any insulating glass available.. The non-metal, Super Spacer perimeter seal provides very low heat transfer to the frame and very high resistance to condensation.

Glass selection can be critical to the ultimate comfort of your new space and often requires a compromise in features, benefits and cost associated with the options.

Critical Glass Design Considerations

Overhead Glass

• Reducing heat gain from direct sunshine can be critical to summer comfort. Reflective and tinted glass is designed for that purpose. Look for a low shading coefficient.
• Glare from direct sunshine can be very unpleasant. Reducing visible light transmission through overhead glass reduces glare.
• Ultraviolet light accounts for approximately 50% of fading in furnishings. Look for reduced UV transmission.
• Thermal efficiency measured by the winter U-value affects comfort and cost of heating. Low E glass reduces loss of radiant heat energy. Lower winter U-values mean better thermal efficiency.
• Safety is a prime concern in overhead glazing. Tempered glass on the outside provides maximum resistance to breakage from impact.
• Laminated glass on the inside minimizes the possibility of falling glass in case breakage does occur. This combination is the safest and practically eliminates the danger from breakage.

Vertical Glass

• Reducing heat gain and glare from direct sunshine can be a critical concern depending on orientation of the room. The reflective glass used overhead may not be desirable in vertical glazing but Low E glass alone or in combination with a tinted glass provides very good solar control and thermal efficiency without the reflective property and excessive reduction in visible light transmission. Low shading coefficient is best for south and west exposures.
• Winter comfort is affected by the thermal efficiency of the glass. Lower winter U-values mean better thermal efficiency.
• Tinted glass reduces visible light transmission, glare from direct sun and provides a colour that may be aesthetically pleasing.
• Glass to the floor must be tempered for safety reasons.

Here are our recommendations for the glass systems we have found to be the most practical for solar control, energy efficiency, comfort and aesthetics.
