Fabric notes
What openness factor measures, why dip coating differs from lamination, and how to read a fire classification.
A 5% open weave transmits light and UV through its openings. Here is what openness factor does and does not control, why colour changes the numbers, and why a dark screen does not mean a cooler room.
A specification sheet may list a European and a US fire standard at once. What each test measures, and what to ask a supplier for before a project is submitted for approval.
Two coating processes look similar on a sample card and behave differently on a building. What dip coating does to a fiberglass yarn, and how to check which one you are buying.
