Hwarrior sound insulation, heat preservation frame steel is slow in heat conduction applies heating blocking middle layer to connect both internal and external of the building, effectively heat preservation and heating blocking, in the meantime using bionic hollow technology to get better sound insulation effect. This system covers also anti-force, anti-violence function. The system applies double layer sealant rubber strips to get perfect heat preservation and sound insulation effect.
Energy-saving and reducing noise
Hwarrior sound insulation, heat preservation system applies heat blocking materials and hollow glass (laminated glass), has very nice effect on heating blocking and sound insulation, so as to save energy on air-conditioner, reducing noise and pollutions.

 Class 4 standard: (daytime 70db, night-time 55db) along both sides of main traffic avenue of the
city, along both sides of internal river path, along both sides of main train track area)
Class 3 standard: (daytime 65db, night time 55db) industrial area
Class 2 standard: (daytime 60db, night time 50db) industry, commercial, residence mixing area
Class 1 standard: (daytime 55db, night time 45db) residence, culture and education area)
Class 0 standard: (daytime 50db, night time 40db) sanatorium area, top class villa area,
high class hotel area etc where they require special quiet areas.
Sound insulation standard: (daytime =50db£¬night time=40db)
Convalescent district, top class villas, private residence, advanced hotel area etc, and places which need special quietness.
General knowledge£ºkey point of sound insulation is DB data, the lower the data is, the lower noise effect. Data is explained as below, each 10db reduces, is to say noise reduced by half or noise double reducing level. |
