Is it necessary to make Truspacer IG with secondary seal?

First of all, we need to understand the structure of the Truspacer.

It is mainly composed of desiccant layer, aluminum foil material, heat insulation strip, wave aluminum strip and butyl sealant, and the butyl sealant on both sides of the spacer.

After high temperature pressing by hot press, it is completely bonded with glass, effectively block the penetration of water vapor, undulating aluminum strips enhance the support between the glass, prevent insulating glass from deforming under pressure, Truspacer spacer IG belongs to single seal, apply to framed doors and windows, because Truspacer comes with butyl sealant and wavy aluminum tape, therefore, no secondary sealant is required.
