Water vapor transmission rate. The trough between the trough of the corrugated plastic strip as the support layer 5 and the adsorption layer 3 is filled with air as a hollow layer, and the thermal conductivity of the spacer seal is lowered by the hollow layer. The support layer 5 can specifically adopt a corrugated plastic strip (PET or PP strip) of 125 peaks per meter, a wavy aluminum strip, a nylon material to make a wave-shaped structure (such as a wavy nylon strip), and the like.

Further, as shown in FIG. 2, the spacer seal further includes: a reinforcing layer 1-2, a reinforcing layer 21, and a reinforcing layer 32, wherein the reinforcing layer 1-2 is adhered to the peak and the adsorption layer of the supporting layer 4.
