Pros
  • Self-adhesive backing installs without glue or fasteners
  • Closed-cell foam resists moisture and humidity
  • Embossed foil facing reflects radiant heat
  • Works across a wide -22°F to 212°F range
  • Roll format cuts to size with scissors or a knife
Cons
  • Only 0.5 m wide and 3 m long, so coverage is about 1.5 m² per roll
  • 5 mm foam gives modest R-value, not a substitute for thick insulation
  • Adhesive can fail on dusty, oily or very hot surfaces
  • Foil facing dents and tears easily during handling

Questions and answers

Is this worth it for a small roof or duct job?
Yes, if you need a thin, waterproof, reflective layer over a small area. It is cheap at $16.36 and sticks on without extra materials. It will not replace thick insulation where real R-value is needed.
How much area does one roll cover?
One roll is 3 m long and 0.5 m wide, about 1.5 square meters (roughly 16 square feet). Buy multiple rolls for larger roofs or duct runs.
Can it be used on pipes and ducts?
Yes. The foam is flexible and the adhesive backing lets you wrap ducts, pipes and metal roofing. Clean and dry the surface first so the adhesive holds.
What temperature can it handle?
The rated range is -30°C to +100°C (-22°F to 212°F). Keep it below 100°C; it is not for stovepipes or other high-heat surfaces.
Is it actually waterproof?
The closed-cell foam and aluminum foil facing resist moisture and humidity. Seams and edges still need sealing if the roll is exposed to standing water.
What is in the box?
One insulation sheet roll, 3 m by 0.5 m, 5 mm thick, black foam with silver embossed foil. No tape or tools are included.
