Introduction

Analysis of the key points of the standard revision

Dimensions	GB/T26540-2011	GB/T26540-2022
Applicable system	Single exterior wall external insulation	Full coverage of new/renovation/existing buildings
Insulation core material	EPS board only	XPS/GEPS/RW board composite system

Main technical upgrade points

1. Multi-dimensional classification system

The types of abdominal wire penetration are now expanded to:

FCT type (non-penetrating single side)

CT type (penetrating single side)

Z type (penetrating double sides)

2. Evolution of typical material properties

icon

XPS board compressive strength increased to ≥200kPa

GEPS board thermal conductivity reaches ≤0.033W/(m·K)

New supporting test specifications

Add a precise measurement method for penetrating samples and develop a special error compensation formula:
R=δ/(λ×α)
Among them, the α value of the new penetrating design is increased to 1.48

Project Implementation Suggestions and Guidelines

Deployment Phase Critical Control Points

Storage and Transportation

Keep stacking flat<2m
