VITEX VITACRYL ROOF INSULATION

Description

Excellent waterproofing material, acrylic based, high elasticity for roofs. It has good adhesion to any structural surface (concrete, brick, wood, metal, etc.) It has excellent resistance to adverse weather conditions, UV radiation and temperature changes, remaining elastic from -30oC to 100oC.

– Insulator for waterproofing roofs
– Resists extreme weather changes
– Elastic
– Certified cold material

SPECIAL FEATURES
Certified by the University of Athens, Department of Physics, for its properties as a cold roof covering material, with:
Initial full-spectrum solar reflectance SR = 0.84 (300-2500 nm) (ASTM E 903-96 and ASTM G 159-98)
Emission factor in the infrared radiation e = 0,89 (ASTM E 408 -71 -2002)
Solar reflectivity index SRI = 106 (ASTM E 1980-01)
Based on official measurements carried out by the University of Athens, Department of Physics, the material can be classified as a cold material with high reflectivity and emissivity values. More specifically, the material presents:
Initial full-spectrum solar reflectance SR= 0,84 (300-2500nm) (ASTM E 903-96 & ASTM G 159-98)
Emission factor in the infrared radiation e = 0,89 (ASTM E 408 -71 -2002)
Solar reflectivity index SRI = 106 (ASTM E 1980-01)
The concept of reflectivity defines the ability of a surface to deflect incident solar radiation, thus giving the percentage of solar radiation that is reflected from the roof.
The infrared emissivity determines the ability of a material to emit heat in the form of infrared radiation.
The SRI combines the two measurements above and determines the ability of a surface to reflect solar radiation and to dissipate in the form of infrared radiation the energy it has absorbed, as a function of the increase in its temperature compared to a standard white and black surface.
These values, which differ from the conventional values given by TOTEE 2010a (Table 3.14 and 3.15) can be used instead of the standard values for the calculation of the energy performance of a building in accordance with the requirements and specifications of Law 3661/2008 (Government Gazette A 89), the Energy Performance of Buildings Regulation – KENAK (F.E.K. 407B/9.4.2010) and the relevant Technical Instruction of the Technical Chamber of Greece (20701-1/2010), by submitting the respective measurement certificates.
Due to all these special characteristics Vitacryl contributes to :
– Energy saving and reduction of energy costs, due to the reduction of air conditioner use and at the same time inductively increases the lifetime of cooling systems.
– To improve thermal comfort for the building users during the warm months.
– The reduction of the urban heat island phenomenon in urban areas (during the summer period the air in urban areas is 3-10°C warmer than in peri-urban areas).
– Reducing air pollution and greenhouse gas emissions.
