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.
Claims21
A ceiling insulation system comprising:
- (a) a support channel having (i) a longitudinal uppermost surface;
- (ii) a pair of generally downwardly extending legs projecting from either side of said uppermost surface;
- (iii) a pair of laterally extending support flanges projecting from said legs;
- and (iv) a pair of oppositely positioned, generally downwardly-facing engagement surfaces formed in said legs extending longitudinally intermediate said uppermost surface and said laterally extending flanges:
- (b) suspension means including
- (i) joist/purlin attachment means;
- (ii) a suspension rod;
- (iii) support channel engaging means in the form of a C-shaped clamping member with two arms each having a generally inwardly extending finger, said fingers extending inwardly beneath said downwardly facing engagement surfaces to support said channel;
- a means for clamping said fingers in their channel-engaging position;
- and
- (iv) means for securing said support channel engaging means to said suspension rod;
- and
- (c) a generally rigid insulation board, said board being at least partially supported on one of said laterally extending flanges of said support channel.
A ceiling insulation grid including a support channel with an uppermost surface portion, two legs extending downwardly therefrom, two laterally projecting flanges extending outwardly from said legs, the terminal ends of said flanges being curled over, and a cross-T channel having a horizontal flange and a central upstanding web the improvement comprising a cross-T channel clip for securing the cross-T channel to said support channel, said clip having a generally C-shaped configuration formed by an upper bifurcated jaw and a lower jaw, said upper bifurcated jaw having inwardly directed teeth for engaging the central web of said cross-T channel and said lower jaw having at least one tang for engaging the horizontal flange of said cross-T channel, said teeth and tang serving to secure said clip to said cross-T channel, said lower jaw further having an upwardly extending lip which engages under the rolled over edge of said support channel flange to restrict upward and lateral movement of said cross-T channel while permitting sliding movement of said cross-T channel along said support channel flange for the purpose of adjustment.
