IDEAL 4000 Tropical Mix

Effective insulation for windows in tropical and desert climates and a low SHGC depends on several factors including the window glazing, tinting, sealing, profile chambers, and spacers. When summer lasts most of the year, energy efficiency and a low SHGC are critical. Aluplast has been creating profiles that are especially designed for tropical and desert climates for decades. With little yearly variation in weather and long lasting extreme temperatures, standard windows can be vulnerable to discolouration and even cracking. This led Aluplast to develop their own special PVC formula for producing casement window frames that can stand up to high levels of sunlight and extreme temperatures without fading, becoming unstable or air leakage. Energy efficient windows do not have to trap heat. They can also be designed to minimize it while lowering cooling costs at the same time. These well-adjusted profiles are available for windows, French doors and Tilt & Slide doors.

Aluplast Tropical Mix Vinyl Windows

With 30 years of experience producing these specialty windows, Aluplast's so-called "Tropical Mix" formula is aimed at areas with up to 180 kcal/cm² per year. This has been certified by multiple external audits and independent institutions such as in Germany, France, Spain, the United States and more.

Whether humid areas like Florida or the dry deserts of Oman and Iran, vinyl windows in such extreme climates must excel at two functions. First of all, they must be durable enough to withstand the climate itself and secondly, have a low solar heat gain coefficient. Special double glazing or triple glazing with the relevant coating can additionally help minimize unwanted heating and loss of cool air. Summers in Dubai, for example, can reach temperatures up to 49°C meaning every little bit of cool air counts.

Installing IDEAL 4000 Windows 

Aluplast's special casement windows are only available in white and should have a surface area of no more than 2 m². Additional installation measures to ensure optimum performance include installing them recessed in the facade and additional shade via corbelling, roof overhangs, awnings, and shutters.

Window orientation is also an important factor when designing new construction. It is ultimately better to prevent heat gain by blocking sunlight before it reaches the window which also has the benefit of reducing glare. Spectrally selective glazing or low e glass is another important factor in heat transmittance in hot climates. This refers to special coatings on the glass panes, or glazing, which blocks much of the thermal gain from solar energy, thereby helping keep the interior air cool. The spectrum of light visible to humans is limited with the vast majority being invisible. Therefore, filtering out infrared and ultraviolet light leads to a lower SHGC, better window performance, and lower energy bills.
