COMMERCIAL BUILDING ENERGY EFFICIENCY - Roof |
Cool Roofs
Over 90% of the roofs in the United States are dark-colored. These low-reflectance surfaces reach temperatures of 150 to 190°F (66 to 88°C) and contribute to:
- Increased cooling energy use and higher utility bills;
- Higher peak electricity demand, raised electricity production costs, and a potentially overburdened power grid;
- Reduced indoor comfort;
- Increased air pollution due to the intensification of the "heat island effect"; and
- Accelerated deterioration of roofing materials, increased roof maintenance costs, and high levels of roofing waste sent to landfills.
In contrast, cool roof systems with high reflectance and emittance  stay up to 70°F (39°C) cooler than traditional materials during peak summer weather. Benefits of cool roofs include reduced building heat-gain and saving on summertime air conditioning expenditures. By minimizing energy use, cool roofs do more than save money – they reduce the demand for electric power and resulting air pollution and greenhouse gas emissions.

Spray Urethane Foam Roofing
Spray Polyurethane Foam has been used as a roofing and insulation material for over 40 years. At one time it was considered to just be an alternative to built-up roofing; foam roofing now protects a wide range of buildings. During this time, foam roofing systems have proven themselves through comprehensive, independent studies to be dependable, long lasting, and very affordable. Today there are foam roofs that have been in place for over 4 decades, and by all appearances they should be able to last indefinitely as long as they are properly maintained.

Hy Tech Roof Coatings-
Insulation rating, insulation values, insulation r factor, insulation r values, radiant barrier, thermal barrier, thermal insulation,Thermal Transfer... Understanding what all these terms mean and how they apply to energy efficiency.:
All the materials that are used in the construction of your home or business absorb and transfer Heat. 80% - 95 % of this heat is transferred, from the warmer side to the cooler side by one or more of the following ways.
1. * CONDUCTION:
Conduction is direct heat flow through matter (molecular motion). An example of conduction, if you lay one end of a butter knife on the burner of your stove, the heat travels by conduction through the metal to the other end that you are holding and it soon becomes too hot to hold. Heat is always conducted from warm to cold never from cold to warm.
2.* CONVECTION is the transport of heat within a gas or liquid.
Example-hold your hand above the stove burner and you soon feel the heat being emitted and transferred thru the air upward.
3.* RADIATION is the transmission of electromagnetic rays through space. We experience infrared radiation every day. The heat that we feel from sunlight, a fire, a radiator or a warm sidewalk is infrared. Although our eyes cannot see it, the nerves in our skin can feel it as heat.
