Structural Plastic Lumber General Installation Guides ...

Expansion/Contraction. Structural plastic lumber expands and contracts along its length based on temperature. A calculation for change in length in inches can be done by using 0.000034 IN/IN/degrees multiplied by its length in inches, and the temperate change of the board. This expansion and contraction on short lengths is minimal, but if you ...

Plastic lattice expansion problem | Woodworking Talk

 · So I was thinking about centering the plastic lattice inside the frame with a couple of screws in the center to keep it centered and still allow for expansion. I’ll need two screws so that the lattice will not rotate and I’m concerned that the expansion might be too much for the screws when the surface temperature from the sun goes over 130˚F.

How much does HDPE sheet expand and contract? | iPoly

HDPE sheet expands more in length than in width, due to its molecular structure. The easiest formula to use for an exact expansion / contraction dimension is as follows: Degrees Fahrenheit: 0.00011 x degree variance (°F) x length in inches. Example: 0.00011 x 30°F temperature change x 96" long sheet = 0.3168" or approximately 5/16".
