Abstract
A heat-insulating connecting member has a warm metal profile, a cool metal profile extending parallel to and spaced from the warm profile, and a pair of parallel and spaced insulating strips bridging the profiles and defining an insulating compartment therebetween. One of the strips is formed with a web projecting generally across the compartment and having an outer edge adjacent the other strip. An infrared-reflecting foil is secured between the web and the warm profile under tension at a spacing from the warm profile between the outer end and the one strip.

A heat-insulating connecting member comprising:
- a warm metal profile;
- a cool metal profile extending parallel to and spaced from the warm profile;
- a pair of parallel and spaced insulating strips bridging the profiles and defining an insulating compartment therebetween, one of the strips being formed with a web projecting generally across the compartment and having an outer edge adjacent the other strip;
- an infrared-reflecting foil between the web and the warm profile;
- and
- means securing the foil under tension at a spacing from the warm profile between the outer edge and the one strip.
