Choosing membrane materials: substrates, coatings and applications

Choosing membrane materials: substrates, coatings and applications

First identify whether the membrane must provide shade, rain protection, daylight or enclosure, then compare actual products. PVC, PVDF, PTFE and ETFE names do not all describe equivalent levels of material composition; abbreviations alone do not define complete performance.

Turn material names into complete specifications

Fabric membranes typically combine a load-bearing substrate, coating and surface treatment. ETFE foil has a different composition. Specify manufacturer, model, composition and application rather than treating a surface-coating name as a full product description.

Screen for suitability before comparing price

Consider structural material properties, project fire requirements, daylight aims and exposure. Read parameter test methods and product applicability. A report for one model cannot be applied to every material from the same brand.

Compare fabrication and aftercare as well

Roll widths, seam processes, colour batches, lead times and cleaning or repair requirements all affect the project. Compare identical specifications and supply scopes, distinguishing material warranty, workmanship warranty and design service life.
