How to choose twinwall and multiwall polycarbonate
Compare panel thickness, cell structure, light transmission, insulation and the intended span. Confirm which face carries UV protection and follow the product-specific installation requirements.
Plan the complete installation system
Panel performance depends on compatible edge profiles, joining channels, fasteners and end-sealing tapes. For transparent solid glazing, compare solid polycarbonate sheet before specifying a structured panel.
Project and cut-to-size support
Provide the opening dimensions, support spacing, exposure and performance goals so the panel and accessory system can be reviewed together.
Frequently asked questions
What is the difference between twinwall and multiwall? Twinwall has two outer skins with one internal cell layer; multiwall is a broader family with additional internal walls or structures.
Can twinwall be cut to size? Many panels can be cut for a project, subject to available stock, tolerances and shipping constraints.
How are panel ends sealed? Compatible venting or sealing tapes and end profiles help manage debris and condensation; follow the panel manufacturer’s details.
