Pure Aluminum

COOLMAX™ Bubble Foil

The typical Malaysia houses receive most of its solar heat gain from the roof due to the horizontal surface receives the highest solar radiation, peaking at about 350 Wh/m2 at mid-day in the tropical sun and it continues to receive the highest solar radiation level throughout the day, from 50% to 85% of the total solar radiation.

The CooLMax™ bubble foil are the best materials that are designed to block 97% of incoming radiation heat, using pure aluminum foil incorporated with low K air cavities to reduce heat gain by conduction

With CoolMax bubble foil, it reduces attic temperature during the day, by up to 12⁰C, down to 38⁰C

As a result of lower attic temperature, ceiling temperature is also reduced by up to 7⁰C, down to 33⁰C, and air conditioning running time drops

Definition of Reflective Insulation

Reflective insulation is a thermal insulation system consisting of one or more low emittance surfaces, bounding one or more enclosed air spaces with a measurable R-Value

made of 2 external pure aluminium foil, covering a double layer of fire retardant polyeth-lene bubble film, and a single core layer of XPE fire retardant foam. Emissivity is low (0.03 to 0.05 for each reflective surface), and it is reinforced with bidirec-tional fiber net. The aluminium thickness are 9 micron for top layer, and 18 micron for bottom layer respectively.

Heat Gain illustration

In tropical climates, 75% to 90% of heat gain occurs through the roof. For single-storey terrace houses, this figure reaches 75%, while for double-storey terrace houses, it exceeds 50%.

Sun rays primarily heat up the roof structure through radiation. With the roof's high emissivity (80%), a significant portion of this radiant heat penetrates the roof space. Consequently, the temperature of the roof impacts the attic temperature, which in turn affects the ceiling temperature. Ultimately, this chain of effects directly influences the cooling load required for the building.
