Lightweight Roofing Systems Reducing Energy Heat Transfer

Of these options s tiles stand as one of the more energy efficient models of the bunch.

Lightweight roofing systems reducing energy heat transfer.

The versatility of vinyl roofing membranes allows it to re cover an existing roof providing both performance and financial benefits. Figure 6 steel roofs cool off quickly whereas tiled roofs continue to radiate heat. Summer performance of a ventilated roof component. 10 dimoudi a androutsopoulos a lykoudis s.

In summer a lightweight insulated roof made from colorbond steel causes less heat to be radiated into your home at night. That s because steel has a low thermal mass so it cools down fast once the sun is off it. Furthermore lightweight vinyl roof systems help reduce the need for other materials that are often necessary to support heavier roof system options. Heat coming through the roof superheats the air in the roof space which in turn conducts heat through the ceiling into the room below.

The added airflow achieved between the tile and roof decking can result in an extended lifespan for the underlayment and components as well as an energy saving reduction in heat transfer through the attic into the living space. Determination of transient two dimensional heat transfer in ventilated lightweight low sloped roof using fourier series. As a manufacturer of metal roofing classic metal roofing systems has taken considerable steps to ensure that our products are energy efficient in terms of reducing summer heat gain. The heat in the building s interior should be reduced by heat sinks natural or hybrid cooling through air infiltration al obaidi et al 2014b al obaidi et al 2014c surface properties such as the colour of the internal surfaces and energy efficient equipment that can considerably reduce internal heat gains mumovic and santamouris 2009.

Light colored and earth toned slate help in reducing the heat absorbed by a building because it has natural reflective properties. Using thermally efficient roofing materials like colorbond steel can help you reduce your cooling costs. Sweetser slate is durable and beautiful with a natural color range and it lasts a long time with little maintenance. A classic metal roof addresses all 3 forms of heat transfer radiant conductive and convective to achieve a roof system of maximum energy efficiency.

And that has the ultimate effect of reducing heat transfer and cooling costs in return. Like many terra cotta tiles they re fashioned into a wave pattern which improves airflow between the decking and the roof surface. 11 äœerne b medved s. The following sections will discuss the principles of reducing heat gain in roofs walls floors and windows.
