Shade
is Protection
Nature has the
ability to be a serene meadow or a menacing force to be reckoned with.
-Knowing
how to manage her power is to our advantage.
Security Shield offers a level of sun control that is often only found on commercially installed sun-screens and window film. A benefit that can be enjoyed in energy savings for years to come.
The sun, by conventional wisdom is really the source of all our power.
It turns seeds into vegetables and provides warmth for us all. Yet it
remains the silent destroyer of furnishings, expensive woodwork and interior
decor. Security Shield not only serves
to protect occupants but interior investments as well. Our solar blocking
abilities deflect 51% of harmful UV rays that are capable of devastating
a buildings interior. Security Shield window barriers are designed to give a uniform tinted look to windows
without obstructing views. Energy is always a concern and shade protection
diminishes heat gain. Rising energy costs are reduced and savings can
be amortized over the life of the product.

Products contracted a nationally recognized, independent testing laboratory
to determine the Shading Coefficient and the effect installation of the
barriers would have on solar heat gain.
The testing determined the Shading Coefficient to be .51. This means, for
a given opening, solar heat gain is reduced by almost 50%.
Reducing the solar heat gain is a practical method for saving energy. For
example, just sixty square feet of glass can admit as much as 12,000 BTU
of heat each hour, requiring one extra ton of air conditioning. By installing
Security Shield Barriers over the existing
glass, the amount of solar heat being introduced through the opening is
reduced by almost 50%.
The following chart represents the solar heat gain for 1/8" clear
glass (ASHRAE reference glazing) and 1/8" clear glass protected by
a Security Shield Window Barrier. Conditions
were simulated for July 21st in Miami, Florida for East, West and south
facing openings. |
