Abstract
A window spacer system for multi-paned window and door lights uses a paper or carboard substrate, generally built up in laminated ribbon structure as a low cost hermetic seal possessing unusual thermal insulating and thermal expansion characteristics. The ribbon may be impregnated or laminated with superior sealants, including polyvinyl alcohol and SARAN (TM) and can be scored or marked for folding into hollow seal sections, from which a peripheral seal frame can be readily manufactured. Metallic foil, in a range of thickness can be incorporated, to enhance the sealing characteristics, and in certain instances to provide a dead-fold characteristic to the seal ribbon.
