Buying Guide

Match foam type to application

Choose neoprene or closed-cell EVA for moisture resistance and vibration damping, and softer open-cell foam for cushioning or padding

Check thickness and sheet size

Confirm available thickness (1/4" vs 1/2") and sheet dimensions to ensure adequate coverage and cutability for your project

Adhesive-backed vs non-adhesive

Adhesive-backed sheets simplify installation on flat surfaces, while non-adhesive foam allows repositioning and heavier-duty fastening

Roofing closure strips for metal panels

Use foam closure strips sized for R-panel roofs to seal gaps, reduce noise, and prevent debris entry under metal panels

Consider sound and vibration performance

Denser closed-cell foams and neoprene offer better sound isolation and vibration damping for automotive and mechanical applications
