* Pressure sensative adhesives will not stick permanently to unfinished wood as the resins will adversly affect the adhesive. The adhesive must be adhered to the glazing for permanence.

** Manufacturers note: No pressure sensitive adhesives are permanent. Temperature, humidity, and the persistance of gravity will eventually overcome bond. The adhesive used on Econospace is much thicker and stronger than the others and because Econospace is lighter, it will work fine for smaller frames. Test results are from an independant lab comparison test using 3" of engagement on glass. Test report available upon request.

*** No instructions included in package. Spacer will move with the glazing the amount of the allowance and possibly move spacer into view. If spacer is used with 1/8" allowance and engaged half on - half off glazing to "center" the glazing, this reduces adhesive engagement and thereby reduces bond strength and longevity.
