Combustible Floor System Loading
Important:
Floor framing for IBV installation will need to
be designed and built to accept substantial dead loads spread
over a relative small oor area. (Figure 1)
The following weights and sizes can be used to
calculate loading. It is the contractor’s responsibility to provide
adequate oor system load capacity.
IBV Weights and Load Calculations:
Total dead load amounts include (but are not necessarily limited
to) the following items and their corresponding weight estimates
as listed below:
1. Isokern unit model weights:
a. IBV-46: 1400 lb
b. IBV-36: 1200 lb
2. Approximate weight of log set: 100 lb.
3. Fire brick and mortar: 350 lb.
4. Facing material: per general contractor
5. B-Vent metal ue: per manufacturer
The oor area for each model is as follows:
IBV-46 @ 53” x 25.25” = 9.30 sq. ft.
IBV-36 @ 43” x 25.25” = 7.54 sq. ft.
Notes:
1. Earthcore is not responsible for structural oor support
details for this replace system. Unless otherwise noted all
oor framing drawings in this manual are merely illustrations
to indicate the presence of an underlying oor system.
2. Consult your local structural engineer for proper oor system
design, sizing and specications.
