Check with your respective Sales Office for length to width ratio (aspect ratio) limitations which will require both lites heat strengthened or tempered.

Reflective glass units that are tempered or heat strengthened will show distortion intrinsic with such heat treatment processes.

Glazing Recommendations for insulating Glass Unit also apply to Reflective Insulating Units. Glazing Recommendations are available upon request.

Capillary tubes are recommended for units that are to be glazed in installations in excess of 2,500 feet elevation change from place of manufacture. The customer must so specify this condition on quotation requests and purchase orders.

4. Wired glass is not to be used with tinted glass.
5. Annealed glass must not be glazed in hazardous locations defined by applicable codes or federal laws. These locations should be glazed with an approved safety glass.
