How to handling & processing PLANITHERM TOTAL+

SGG PLANITHERM TOTAL+ must always be assembled into a double or triple glazed unit. The coating is generally placed on face 3 (and 5) of the unit, though it is possible to place the coating on face 2 without affecting the U-value. Appearance may vary slightly, so it is important to maintain consistent coating positioning throughout a particular façade.

See the handling guidelines brochure for more details.
