The advantages of metal as a roofing material are efficiency and sustainability. We combine these attributes and integrate this roofing into the heating and cooling system. To learn more please go our Solar Systems page.
Radiant Floor Overview
Radiant heating systems convert a floor into a large area, low-temperature radiator. Warm water is circulated through closely spaced plastic tubing that is embedded in the floor slab or attached to the underside of wooden subflooring. Underfloor insulation is a critical component. Zoning depends on advanced manifolds that regulate flow or modulate the water temperature in different tubing runs. Sophisticated controls regulate the system using temperature sensors in the slab in each room being heated as well as outdoors. [Read more]
Metal roofs add energy efficiency and a reflective surface when natural metal or light colors are selected. They can enhance the look of your home and provide attic space/storage area.
A Metal Roof will increase the appraisal value of your home and last for years and years–far longer than a typical roof system. Aesthetically pleasing and energy efficient, metal roofs can be an enduring and attractive option.
High solar reflectance and high infrared emittance roofs incur surface temperatures that are only about 3°C (5°F) warmer than the ambient air temperature, while a dark absorptive roof exceeds the ambient air temperature upwards of 40°C (75°F).
In predominantly warm climates, the high solar reflectance and high infrared emittance roof drops the building’s air conditioning load and reduces peak energy demands on the utility. In North American climates, being predominantly cold, a more moderate reflectance and a low emittance result in a warmer exterior roof temperature, which reduces heat loss from the building.
Temperature, heat flow, reflectance, and emittance field data have been catalogued for a full 3 years for 12 different painted and unpainted metal roofs exposed to weathering on an outdoor test facility. Habitat homes were tested unoccupied for a full summer in Ft. Myers, Florida.
Measurements showed that the white reflective roofs reduced cooling energy consumption by 18-26% and peak demand by 28-35%. The houses were side-by-side, and had different roofing systems designed to reduce the attic heat gain.
Results show that a judicious selection of the roof surface properties of reflectance and emittance represents the most significant energy and cost-saving options available to homeowners and builders.
Metal roofing is a proven product, more durable than most available roofing systems. Metal roofs simply last longer, and is often the roofing choice for many government, school and industrial buildings.
Metal roofs rate high in wind, fire, and hail resistance.
Not only will a metal roof keep your house comfortable, regardless of the weather outside, it may actually lower your air conditioning and heating bills.
According to the National Association of Homebuilders Research Center, 20 billion pounds of asphalt shingles are dumped into US landfills every year. The recycled content of the steel in a metal roof is far superior to asphalt. Metal roofs also have a low per unit area weight, making it possible in most cases to install directly over existing roofs, saving removal and disposal costs.
