7.FAQ
Q: What is the different of the pre-expansion and post expansion? Which one is better?
A: Pre-expansion is better. Post expansion will not only damage the doors and windows after curing, but also it will leads the cost of construction higher because more foam must be cut.
Q:What’s the impact for the PU foam with a big bubble or uneven cell?A: Small bubble or smooth cell is a common performance for good quality PU foam. Big bubble foam will cause thermal and sound insulation ability reduce and it may even be water leakage.
