Single-Glazed Windows, Clear Glass

Relative to all other glazing options, single-glazed with clear glass allows the highest transfer of energy (i.e. heat loss or heat gain depending on local climate conditions) while permitting the highest daylight transmission.

Whole Window Properties – Single-Glazed, Tinted Glass

The primary purpose of bronze or gray tinted glass is to reduce solar heat gain. But, it also reduces visible light as compared to clear glass or even other standard tinted glass products such as green and blue tints which offer significantly higher visible light transmission. Tinted glass is useful in controlling glare but solar heat gain and visible light transmission may be reduced relative to the performance of alternate glazing options such as low-E glass with moderate or low solar gain.

The tint has no effect on the U-factor but reduces solar heat gain which may be a benefit in the summer and a liability in the winter depending on local climate conditions.
