Conventionally, “green products” are fully organic and sustainable. wedi foam based products are therefore not “green”. However, the process of manufacturing is engineered to not harm our environment. Extrusion agents used are CFC free and the product obtained a “Global Warming Potential “ rating as per UN charts of 1 . Global-warming potential (GWP) is a relative measure of how much heat a greenhouse gas traps in the atmosphere. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide. A GWP is calculated over a specific time interval, commonly 20, 100 or 500 years. GWP is expressed as a factor of carbon dioxide (whose GWP is standardized to 1). For example, the 20 year GWP of methane is 72, which means that if the same mass of methane and carbon dioxide were introduced into the atmosphere, that methane will trap 72 times more heat than the carbon dioxide over the next 20 years. The substances subject to restrictions under the Kyoto protocol either are rapidly increasing their concentrations in Earth's atmosphere or have a large GWP. wedi foam based products also protect organic structural parts of buildings such as wooden parts against rotting , replacement and mold, thereby actively prolonging the lifetime of an installation, resulting in a savings of resources and energy. In addition, wedi foam based products add insulation and can eliminate heat leaks of building envelopes insulation or may dramatically improve the performance of floor heating systems when installed underneath such systems, and help conserving energy. wedi building panel can also be used actively on facades to add to the efficiency of older insulated walls or standard batts insulation. Especially also in areas often subject to insufficient insulation and heat loss such as window or door frame areas.
