Questions and answers
- Which is better for a metal roof?
- A. Its self-adhesive backing sticks to color steel tile roofing, and the closed-cell foam handles moisture. B is a reflective roll better suited to attics and walls.
- Which works better on windows?
- B. The wide 24 in reflective roll is sized for window and wall coverage. A is narrow at 0.5 m and its adhesive is aimed at roofs, ducts and pipes.
- Which lasts longer?
- A has a closed-cell foam core that resists water and a stated -30°C to +100°C range, so it holds up in damp, hot or cold spots. B's bubble film is thinner in structure and has no stated temperature range.
- Is B worth the extra $10.63?
- Only if you need the wider 24 in by 10 ft coverage and the B2 fire class. For small duct, pipe or roof patches, A covers the job for less.
- Do I need extra tape for either one?
- A no, it is self-adhesive. B yes, plan on foil tape, staples or an adhesive for seams and edges.
- Can I use either inside a wall cavity?
- Both are sold for wall use, but A's closed-cell foam is the safer pick where moisture is a concern. B is better as a radiant barrier facing an air gap.
