Heat reflective laminated glass cuts solar radiation by 89% in Kuala Lumpur high rise building

Corporate headquarters of the Malaysian National Insurance

The Menara MNI building, the corporate headquarters of the Malaysian National Insurance company is located along Jalan Pinang in Kuala Lumpur's busy 'Golden Triangle' downtown area. The 27-floor high rise is equipped with a state-of-the-art, 'intelligent' building automation system that uses heat-reflective laminated glass based on DuPont^™ Butacite^® PVB for its external glazing.

The heat-reflective laminated glass incorporated in the MNI building is produced using an advanced coating process, called 'the sputtering method' that produces excellent solar heat control. In this instance, the glass is able to reflect and absorb 89% of total solar radiation.

The laminated glass used was constructed with 6mm blue glass + 0.76 mm Butacite^® clear PVB plus 3 mm or 4 mm clear glass with a titanium coating on the second surface.

In Malaysia, architects are required by law to use laminated, tempered or wired glass for external glazing in high-rise buildings. Heat reflective glass is gaining widespread usage due to its solar-heat control, aesthetic and acoustic qualities. Laminated glass, in particular, is gaining popularity as a heat reflective glass option since it preserves the metal coating better than other types of glass.
