What is Solar Heat Reflection?

Solar Heat Reflection is a critical performance metric for modern skylights that quantifies their ability to manage solar energy transfer into your living space. This property is particularly important for roof-mounted glazing like Skyseal skylights, which receive direct sun exposure throughout the day.

When sunlight strikes a skylight, a portion of the solar energy is transmitted through the glass into the interior space, while another portion is reflected back to the atmosphere. Solar Heat Reflection specifically measures the percentage of total solar energy that the skylight system effectively redirects away from your home. The higher this percentage value, the more effective the skylight is at preventing unwanted heat gain during warmer periods.

For example, a Skyseal skylight with a Solar Heat Reflection rating of 70% means that 70% of the sun's thermal energy is reflected away from your interior, while only 30% passes through the glazing system. This significant reduction in solar heat gain helps maintain comfortable indoor temperatures without excessive reliance on air conditioning systems, particularly important during summer months or in rooms with substantial skylight coverage.

Skyseal achieves enhanced Solar Heat Reflection through specialised glazing technologies including advanced Low-E coatings, tinted glass options, and multi-pane configurations with insulating gas fills. By carefully engineering these elements, Skyseal skylights deliver an optimal balance between beneficial natural light transmission and controlled solar heat gain, contributing to improved energy efficiency, reduced cooling costs, and superior year-round comfort in your home.
