Does temperature cause Precision Board to expand or contract?
Yes it does. Virtually every material, whether it is metal, glass, wood, stone, or HDU, expands and contracts as it gets warmer and cooler. This percentage of movement, and it is different for every material, is called its Coefficient of Thermal Expansion or CTE. The CTE of Precision Board is 40 x10-6 xF. When an architect designs buildings, dams, houses, etc. the CTE of each different material is taken into consideration to allow for its required movement. When designing signs it is the same. The CTE of the metal framing, plastic faces, metal backing, stone framing, etc. need to be considered and movement allowed. Call us to assist you with calculating the movement of Precision Board.
