Is bubble foil insulation any good?

Is bubble foil insulation any good?

(The bubble wrap layer is unnecessary, since it adds cost to the material without adding any useful thermal performance.) Since the main benefit from foil-faced bubble wrap is due to its radiant-barrier facing, the product is basically worthless unless it faces an air space.

What is single bubble insulation?

Single bubble insulation is a cost-effective way to keep your building cool in the summer and warm in the winter. Single bubble is an 1/8” thick single layer of bubble insulation primarily used in warm climates.

What is bubble wrap insulation?

Bubble wrap insulation is made of one or two layers of foil with encapsulated air bubbles pressed in between the layers. It is a radiant barrier, which means it has the ability to reduce radiant heat, keeping your home, office, pole barn or warehouse cool and fresh in summer and comfortably warm in winter.

What is the R value of bubble foil insulation?

A. Martin Holladay, editor of Energy Design Update, responds: The R-value of 3/8-inch-thick foil-faced bubble wrap is about 1.3. The R-value of 3/8-inch-thick foil-faced expanded polystyrene foam is about 1.6. By contrast, 2 inches of extruded polystyrene insulation has an R-value of 10.

What is the difference between single and double bubble insulation?

They are both radiant barrier reflective foil insulation products. The only difference is single bubble foil has only one layer of polyethylene bubble between the two exterior layers of highly reflective aluminum foil. For almost all projects, both residential and commercial, we recommend a double bubble product.

What is the insulation value of bubble wrap?

Martin Holladay, editor of Energy Design Update, responds: The R-value of 3/8-inch-thick foil-faced bubble wrap is about 1.3. The R-value of 3/8-inch-thick foil-faced expanded polystyrene foam is about 1.6. By contrast, 2 inches of extruded polystyrene insulation has an R-value of 10.

Why is bubble wrap a bad insulator?

Air is a good insulator, and as bubble wrap is nothing but air bubbles trapped inside plastic sheets, it serves as a good insulator. The air in a confined space tends to resist temperature changes. Bubble wrap will increase the resistance to heat flow by a factor of one.

How long can bubble wrap last?

between 5 and 7 years
Bubble Wrap Life Bubble wrap should last between 5 and 7 years on your windows.

Is bubble wrap insulation flammable?

All rFOIL™ reflective insulation products are produced with aluminum or metalized polyester and polyethylene (plastic). None of these materials is flammable or a fire hazard. The material is more prone to melting during a fire, rather than adding to the burning of the structure.

How long does foil insulation last?

As a general rule, insulation should be replaced or retrofitted every 15 to 20 years. However, it may need replacing or retrofitting sooner depending on the type of insulation installed, the R rating of the original insulation, compression and movement over time, and whether any damage has occurred.

What is reflexreflex-air® single bubble insulation?

What is a single bubble reflector?

All our reflective single bubble products: are one layer of polyethylene industrialized air bubbles bonded between exterior reflect (blocks) 94% of the radiant heat that strikes its surface across an air space, are industrialized-strength lightweight yet durable,

What is the R-value of bubble insulation?

Any bubble insulation that is approximately ¼” thick can ONLY achieve an average r-value of 1 to 1.5 on its own. Any additional R-value is achieved by the use of DEAD air spaces around the reflective product or in used in conjunction with other mass insulation products like fiberglass, foam, etc.
