new design Germany technique high quality energy efficient louver fiberglass insulation windows

GRP technique introduced from Germany sound isolation and heat insulating fire rated and lightweight service life min 30years

Fiberglass energy efficient louver windows:  

Performance of energy-saving industrial windows:

Light quality and high strength. The wind pressure resistance performance of GRP doors & windows can reach 5.3 Kpa, which surpasses 8-band level of the national GB/T7106-2002 standard.Energy-saving and temperature preservation. The heat transmission coefficient of the structure of GRP profile and H20-2 GRP is 2.0W/(M2 . K).Excellent sealing performance. The air tightness reaches level 5 of GB/T7107-2002, while the water-tightness complies with level 4 of GB/T7107-2002.Energy-saving and environment friendly.Fine sound insulation. The sound reduction index of GRP window & door is 30dB.Corrosion resisting. It is used especially in rainy, wet and coastal area as well as the place where there is corrosive medium.Weather resisting property. The thermal deformation temperature is over 200°C, with good resistance to high temperature. Moreover its low temperature resistance is much better. The change of temperature can not affect the common on-off function of the windows & doors.Long service life. The average service life of GRP windows & doors is over 30 years.Many color choices for frame profile. There is a variety of colors available, and especially the surface can be made into grain as the wood windows & doors.Outstanding insulation capability. It can be used in the building construction of some special fields, such as electrical facilities, temporary building, communication field.Excellent damping capacity. Owing to the structure of GRP profile, the modulus of elasticity is 20900MPa.High safety and hard to broken. Due to the particular layer, GRP windows & doors can ensure confidentiality.

GRP window panel introduction: 

Glassfiber Reinforced Plastic (hereinafter as GRP) is one kind of new energy efficient building material. It is hollow in double sides and furnished with plates, chooses glassfiber as main material, treated by the technologies of light reaction and polishing. Besides common functions of high strength and wonderful lighting performance, GRP possesses some special features. Firstly it is energy-saving and environmental-friendly; meanwhile, GRP is one kind of heat-resistant material, and is also insulated against noise.
