ROOF UMBRELLA

The ROOF UMBRELLA is...


ROOF UMBRELLA is preventive insulate solution. Traditionally insulation products were all corrective. Sunlight hit the roof then reflects heat or insulate inside the building. ROOF UMBRELLA's method is as its named, just like having an umbrella on your building. Shutting direct sunlight before it hits the roof. It decrease the temperature of roof as the result, inside temperature can be maintained lower. Other benefit is protecting the roof from UV, decrease the noise during rain. The squall in Southeast Asia is very strong and it makes loud noise when rain hit the roof of factories or supermarket. As "Umbrella" protects the roof from the rain to hit directly , noise can be decreased.

      

Beneath the roof

       
Reducing the solar radiation load for the roof surface and decreasing radiation heat for the indoor, Thereby, Improving the indoor environment, and as a result produced a big energy saving.  

The advantage of against thermal barrier coatings (paints).
****The sustainability of the thermal barrier effects****


Thermal barrier coating (paints) exercise thermal barrier effects by high thermal reflectivity. However, performance degradation by dirt on surface is inevitable. Thermal barrier coating (paints) has a major issue that it is difficult to maintain performance of thermal barrier effects. Thermal barrier system of ROOF UMBRELLA is not due by reflection. ROOF UMBRELLA is based on the idea of shading. Even if the surface of sheet gets dust, heat shield performance does not degrade and it can be maintained for long term.

Strong weather resistance

Sheet material is made from polyethylene with coating special treatment on the surface which gives strong weather resistance.


The test results proved that heat shield could resists to the weather for approximately 27.5 years (400 hrs in test devise equivalent to 1 calendar year) under the standard measurement for quality preservation set by the sheet manufacturer. Even setting 1,000 hrs is equivalent to 1 year by considering severer conditions such as strong sunlight and many other elements on top of the roof, ROOF UMBRELLA could perform sufficient function for a definite period.

Effect of ROOF UMBRELLA on reducing indoor noise caused by rainfall

    
 ROOF UMBRELLA as an umbrella for the building. Because ROOF UMBRELLA is installed by covering the roof with the sheet, it prevents most of rain hitting the metal roof directly. As a result, it will significantly reduce loud rain soundhitting the steel roof and provides environment with less noise especially   
 during  the squall season in Southeast Asia.
