Sub Floor Material Calculator
This simple sub floor materials calculator will provide you with the lineal feet of floor joist needed, the number of sheaths to cover the floor and how much glue and how many screws it takes to attach the sheathing to the joist.
The screw count is a bit high at times but this will allow for losing some.
GlueOne tube of glue at 16 O.C. would do just over 3 sheaths.
19.2 O.C. = just over 3.5 sheaths
24" O.C = just over 4.5 sheaths
On a warm day you will be able to stretch that a bit, and on a cold day with cold glue, you will be hard pressed to get that amount of coverage out of your tube of glue.
Screws16" O.C. = 53 screws a sheath
19.2" O.C. = 46 screws a sheath
24" O.C. = 39 screws a sheath
Floor OpeningIf there is an opening in your floor enter the sq footage in the "Floor Opening" field.
It will update all the amounts needed, but it won't take into account any joist that may have to be doubled and or beams that would need to be added because of this opening.
