Too often, maintaining a comfortable temperature in a building depends on expensive cooling or heating. One cost-effective solution could be to select the appropriate glass for each application.

Glass in a single thickness is a poor insulator, therefore to effectively control heat loss and heat gain, INSULVUE Insulated Glass Units (IGU’s) are most efficient.

INSULVUE IGU's are manufactured from two or more panes of glass held apart by a metal spacer and bonded with a primary and secondary seal, trapping dehydrated air between the glass.

Clear INSULVUE is almost transparent to radiant solar heat. However, the outer glass can be replaced with a solar control performance glass from the SmartGlass range. By combining such a glass in an INSULVUE unit the performance of the solar control glass is enhanced.

INSULVUE is available in various types of glass and combinations thereof, in order to offer a wide range of performance characteristics and aesthetic appearances. For instance, INSULVUE units containing glass with a low Emissivity coating are recommended where a good thermal insulation is desired.

Refer to Technical Data sheets for information regarding INSULVUE glass combinations and their performance characteristic.

• Air-conditioned projects in areas with a high diurnal range or with extreme ambient temperatures.
• Airport or other control towers to ensure optimum visibility and reduced internal reflection.
• Computer rooms for strict atmospheric control
• Special commercial and industrial glazing
• Condensation reduction
• Cold stores and refrigerator doors

To assist in optimising design and specifications, PFG Building Glass offers a range of technical advisory service covering most appropriate product for each application, economy, thermal stability, Building Regulations, guarantees and local and international product standards. For maximum benefit to the project this should ideally commence before working drawings begin.

The edges of all heat absorbing glass should be polished to reduce the possibility of thermal breakage. Contact PFG Building Glass for a detailed Thermal stress calculation.

NOTE:
1. For efficient insulation, a 6 mm air space should not be used where the minor dimension exceeds 1000 mm.
2. A thermal stress evaluation must be requested when glass with a high heat absorption is utilised in the Unit.
3. Distorted reflections are likely when a reflective glass is incorporated in InsulVue due to temperature and atmospheric pressure fluctuations.
4. *Sizes in excess of 3000x1500 are available on request.

It is imperative that PFG Building Glass be consulted timeously regarding the lead times for supply of product.
