JG 149-2003External thermal insulation composite systems based on expanded polystyrene (English PDF)

Foreword

This standard stipulates the building energy-saving products widely used in wall insulation.

This standard is not equivalent to the use of EOTAETAG004 "Technical Guide for European Technical Certification of Composite Exterior Insulation Systems with Finishing Layer", ?NORMB6110 "External wall composite insulation system composed of expanded polystyrene foam and surface layer", CEN/T C88/WG18N166 "Specifications for Expanded Polystyrene Exterior Insulation Composite System", ICBOESAC24 "External Thermal Insulation and Finishing System Acceptance Specifications". root According to China's national conditions, some technical performance indicators have been adjusted.

In the test method, this standard is not equivalent to the use of EIMA101.86 "external insulation and decoration system resistance to rapid deformation impact test Law, ASTM D2794-93 "Anti-deformation test method for organic coatings (impact)", prEN13497 "External wall insulation for building insulation products" Impact Resistance Regulations for Insulation Composite Systems, EIMA 101.01, Test Methods for Freeze-Thaw Resistance of Exterior Insulation and Finishing Systems, ASTME 2134-01 "Methods for Determination of Tensile Bond Strength of Exterior Insulation and Finishing Systems", prEN13494 "Construction Insulation Products Adhesives and Finishing Glues and Protection Determination of tensile bond strength between warm materials", ASTME 2098-00 "Exterior wall insulation and finishing system PB type reinforced glass fiber mesh Determination of tensile rupture strength of cloth after soaking in sodium hydroxide solution", prEN13496 "Mechanical insulation product glass fiber mesh mechanical can measure".

This standard is the first release and will be implemented as of July 1, 2003.

The "expanded polystyrene board should be flame retardant" in this standard 5.3 is mandatory.

Appendix A, Appendix B, Appendix C, Appendix D, Appendix E, and Appendix F of this standard are normative appendices.

This standard was proposed by the Institute of Standards and Ratings of the Ministry of Construction.

3 Terms and definitions

The following terms and definitions apply to this standard.

The insulation and finishing system placed on the outside of the outer wall of the building is made of expanded polystyrene board, adhesive and anchor bolts and plastering glue if necessary.

And system products composed of alkali-resistant mesh cloth and paint. The thickness of the protective layer of thin plastering should be controlled in. ordinary type 3mm ~ 5mm, strengthen Type 5mm ~ 7mm. The system is connected to the base wall by means of bonding and fixing, and can also be supplemented with anchor bolts. The basic structure is shown in Table 1 and

Table 2.

An external wall that acts as a load-bearing or retaining function in a building, which may be a concrete wall or a variety of masonry walls.
