Galvalume Roof Energy Savings

This good thermal reflectivity translates into energy savings by reducing cooling costs in the summer and heating costs in the winter.

Galvalume roof energy savings.

This highly reflective coating uses cool pigments in the paint to increase solar reflectance and lower the surface temperature of the roof. If the roof maintains a more constant temperature however there is less stress on the roof from thermal shock thus making the product more durable and last longer. It is common for many buildings to use galvalume roofing as an initial cost saving measure. The main disadvantage of galvalume steel roofing material is the initial cost of the product which is double the cost of a shingled roof.

Major roof costs include upfront installation materials and labor and ongoing maintenance repair recoating and cleaning. Noncombustible class a rating. Roof products visit the roof products page for usage tips and buying guidelines. The most effective energy saving finish for metal roofing is commonly referred to as cool metal roofing.

Such a roof can be reasonably expected to be some 50 to 60 degrees cooler than a dark color asphalt shingles roof. Lighter color roofs reflect sun s heat much better than darker colors. Cool metal roofing systems help reduce the energy need of air conditioned buildings and makes. Yet none of the energy savings will be realized if the energy star rated material is not properly installed.

Disadvantages of galvalume steel roofs. Tests have shown that only half as much heat from solar radiation is transmitted into a building fitted with a galvalume roof compared to a galvanized roof and almost one third less heat compared to a terra. Although there are inherent benefits in the use of reflective roofing before selecting a roofing product based on expected energy savings consumers should explore the expected calculated results that can be found on the department of energy s roof savings. Even at r50 cool roofs can produce a measurable cooling energy savings compared to a low albedo roof even if it comes without a noticeable difference in comfort for the occupants.

In fact a high end kynar 500 white metal roof is energy star rated and classified as a cool roof by the cool roof rating council. Painting and maintaining aging galvanized and galvalume roofing. Good thermal reflectivity properties assists with energy savings year round. Cool roofs can save money several ways including energy savings rebates and incentives hvac equipment downsizing and extended roof lifetime.

And galvalume as well as kynar 500 coated and coolroof rated g 90 steel offers exceptional heat reflectivity resulting in lower energy load on homes and hvac equipment resulting in improved interior comfort and energy savings for homeowners. The failure is either in the paint resin or the manufacturing process when the finish was adhered to the metal coil.
