BMI CoolRoof System

Cooler Spaces, Significant Savings

Malaysia’s tropical climate is typically hot and humid all year round, which can cause high indoor temperatures. To cool down interior spaces, most homes and commercial buildings typically use air-conditioning throughout the day. However, this leads to high electricity bills and negatively impacts the environment.

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.

How does CoolRoof work?

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.
