Cool Roof, Cool Home

Cooling Your Home Naturally

The good news is, there is a better solution to cool your spaces: cool roofs. Ideal for Malaysia’s climate, the BMI CoolRoof® System limits heat transfer through the roof and helps cool the indoor environment naturally. In addition, the system combines the benefits of radiant heat reflectivity and ventilation gap to enhance roof performance in hot and humid climates. 

Extensive research in Malaysia and Europe found that buildings with BMI CoolRoof® System recorded a cooler temperature of up to 10°C* compared to properties with conventional roofs. This is due to the system’s complete solution, which comprises five protective elements that fit seamlessly under the roof tiles:

1. BMI roof tiles: the first layer to facilitate heat reflection from BMI MONIER roof tiles 

2. BMI ThermaFoil® / RadenShield®: a high-performance reflective underlay that serves as a heat barrier by reflecting up to 97% radiant heat

3. Counter Battens: elements that form a passageway and air gap to ventilate hot air between the roof tiles and underlay.

4. BMI Compactroll® Plus: a breathable, waterproof dry fix solution that replaces traditional cement mortar and significantly contributes to a cooler indoor environment; it also has a water-repellant sleeve with a high ventilation value

5. BMI Pest Guard: comb-like eaves that facilitate ventilation while preventing birds, bats, rats and other pests from entering and nesting on the roof. 

Through these five key elements, BMI CoolRoof® System reduces heat build-up and heat retention on the roof while ensuring natural airflow, resulting in lower indoor temperatures. When homes become naturally cooler, there will be less air conditioning usage, which translates into savings on electricity bills. On top of this, there are no maintenance costs as BMI CoolRoof® System does not use electricity or mechanical devices.
