Abstract

A ceiling insulation system for commercial buildings. The present invention provides an attractive ceiling panel system with a functional insulation and water vapor barrier system with an insulating R-value of 44 and a perm rating of 0.4. A hat-shaped channel is suspendable from bar joist, steel purlin, or wood joist by using one of three different suspension fasteners. A C-shaped clamp with locking ring, a cylindrical rod and two spring clamps complete the suspension subassembly. Channel junction clips and board edge clamps are used to insure the integrity of the system and enable a high insulation value and a low perm value.
