Abstract
An insulated closure panel is disclosed, in the preferred embodiment of the present invention, for closing off openings under floors and roof decks where prestressed double tee concrete construction spans are used. The closure panel includes an insulating core sandwiched between two facing members. The top and sides of the facing members are undersized from the top and sides of the core, thus allowing the closure panel to be inserted into the opening of the construction spans such that the core can be snuggly fit in the opening while avoiding chipping of the facing members or avoiding pulling the facing members away from the core. The closure panel can be held in the opening of the construction span by foam type construction adhesive. Further, caulking can be added in the groove formed between the top and side edges of the undersized facing member and the surface of the construction span for providing a seal therebetween. The facing members can be formed from various materials and have various finishes according to the construction job.
