GB/T 31543-2015Test methods for wind uplift resistance of single-ply roof assemblies (English PDF)

3.1 Monolayer membrane roofing system,

Dominated by the grass-roots roof, insulation materials, waterproofing membrane composition, the use of the web using a single layer exposed, coil and fixed mechanical insulation materials

Or bonded on the roof in the form of grass-roots.

3.2 Mounting fixationcomponents

The waterproofing membrane, related materials mechanically fixed to the roof of grass roots members, including fixing screws, gaskets, sleeves and layering and the like.

3.3 Gas barrier material airbarrier

Air-permeable barrier material. When using mechanical fixation install membrane, gas barrier material should be installed on the base, and wrap the entire roof

Piercing the roof and all parts.

3.4 Vapor barrier material vaporretarder

One kind of material can prevent moisture from entering the roof system.

3.5 Wind exposing winduplift

Due to pressure caused by the various components of roofing systems or roofing systems, roofing systems so that the force from the grassroots. Wind and through revolving

Over the surface of the building, causing the roof surface pressure falls (negative pressure); construction of the air flow in the roof below the basic level (positive pressure), these two pressure

Force formed to make up synthetic roofing system pressure, wind exposing may be by the wind beneath the roof caused.

3.6 Roof grassroots roofsubstrate; roofdecking

Roof waterproofing and thermal insulation systems constructed from structural layer below the fixed effects.
