Patent U.S. # 5317853 / CAN. # 2115722
|Question:||How much space should I leave around my panel?|
For a 1/4" Spaceball ( 260p) 5/32 of a inch is suggested per side and top and bottom. During the drier time periods you could allow for an additional 1/16. This would allow even more expansion space if the panel is exposed to excessive or extreme humidity changes.
|Question:||How many space balls are used per door?|
We suggest two space balls per side, and top and bottom. If the door is extra wide we suggest putting 3 space balls in the top and bottom rails. This would allow for the additional weight of the panel.
