Since 2005,building energy efficiency standard has been largely improved and by year 2010,constructions in cites and towns must reach 50% of energy saving standard and new buildings must reach 65%.Domestic energy saving constructions have just started up and mainly use polystyrene as material. To achieve energy-saving goals in 2020, we need to adopt energy saving measures for 43 billion square meters outerwalls.
To popularize outerwall insulation is one of the effective ways to reduce energy consumption. The main energy loss of our housing are walls, taking up 50%, roofs, taking up 10%,windows, taking up 25% and floor, taking up 15%. Thus insulating of wall and roof are very important part of energy saving. How to choose a safe and environmental insulating material is the crucial point of the development for insulating industry.
Polyurethane rigid foam has advantages in cost performance in outerwall insulating materials and will surely encounter sharp growth when markets start.
Among insulating material of developed countries, polyurethane takes up 75% of market share while polystyrene and glass wool take up 5% and 10%. But currently, PU rigid foam occupies less than 10% of domestic construction insulating materials, construction insulating industry will be the most promising application for PU rigid foam consumptions.
It is said that American PU rigid foam market mainly applies to construction industry with 55% and cold industry taking up 18% and insulating industry taking up 10% and package and transportation industry taking up 8% and 6%. The consumption proportion is similar in
