Weight of Standard Drywall panels -

Regular Drywall Panels. To convert from PSF to kG/M^2 multiply PSF x 4.89

Panel Size /Weight /Lbs/SqFt /PCF /kG/M^3

4' x 8' x 3/8" = /45 lbs. /1.406 /42 /675
4' x 10' x 3/8" = /56 lbs. /1.406 /42 /675
4' x 12' x 3/8" = /67 lbs. /1.406 /42 /675
4' x 8' x 1/2" = /54 lbs. /1.6875 /42 /675
4' x 10' x 1/2" = /68 lbs. /1.6875 /42 /675
4' x 12' x 1/2" = /82 lbs. /1.6875 /42 /675
4' x 8' x 5/8" = /74 lbs. /2.3125 /42 /675
4' x 10' x 5/8" = /92 lbs. /2.3125 /42 /675
4' x 12' x 5/8" = /110 lbs. /2.3125 /42 /675
4' x 8' x 3/4" = /90 lbs. /2.81 /42 /675

Firecode Core Panels

4' x 8' x 5/8" = /70 lbs. /2.1875 /39.73 /638.5
4' x 10' x 5/8" = /88 lbs. /2.1875 /39.73 /638.5
4' x 12' x 5/8" = /105 lbs. /2.1875 /39.73 /638.5

Medium Density Hardboard – 43-60 PCF typical density, or 690-960 kG/m^3

To convert lb/cu ft into kG/m^3, multiply by 16.04. To convert the other way, divide by 16.04.

Concrete weights approx. 3600 lbs/cu yd when cured, about 3900 pounds wet.
133 lbs/cu ft, or 2133 kG/M^3 -

MDF - approx. 68 pounds per ½” 4x8 sheet or 2.125 PSF, 53 PCF, 850 kG/M^3

Glass = approx. 3.8 times weight per unit thickness of sheet rock - roughly 161 lbs for 4x8 sheet of 3/8” glass.

The surface density of ¼” plywood is 0.74 lb/sq ft, or 23.68 pounds per 4’x8’ sheet.

The surface density of 3/8” plywood is 1.11 lb/sq ft, or 35.5 pounds per 4’x8’ sheet.

The surface density of ½” plywood is 1.48 lb/sq ft, or 47.36 pounds per 4’x8’ sheet.

The surface density of 5/8” plywood is 1.85 lb/sq ft, or 59.18 pounds per 4’x8’ sheet.

The surface density of ¾” plywood is 2.22 lb/sq ft, 71.04 pounds per 4’x8’ sheet, 35.5 PCF, 562.5 kG/M^3

A dry 8’ 2x4 weighs about 10 pounds, 2x6 about 15.7 pounds; density about 4.28 PSF for 2x lumber. This puts 2x lumber at roughly the same density as a layer of 5/8 and a layer of ½” drywall. 2x10 about 28 pounds per 8' length, or 3.5 lbs/lin.ft. –

2x10 framing on 24" centers adds approx. 2 lbs PSF dead load. 2x10 on 16" centers adds 2.7 PSF to dead load.

2x8 framing on 24" centers adds approx. 1.6 lbs PSF dead load. 2x8 on 16" centers adds 2.1 PSF to dead load.

2x6 framing on 24" centers adds approx. 1.2 lbs PSF dead load. 2x6 on 16" centers adds 1.6 PSF to dead load.


Celotex has an average density of 16.8 PCF, or about 39% as dense as gypsum wallboard.

Steve

When calculating for load purposes, spans, etc, always round UP a bit (use 2.4 PSF for 5/8 drywall, or even 2.5) - that way, you won't UNDER-build and invite problems.
