Our most popular bubble foil insulation is used for applications in metal buildings, pole barns, basements, crawl spaces, and many other places that require a vapor barrier. Double bubble foil has a double layer of polyethylene bubbles that acts as an extra thermal barrier to prevent condensation.
Bubble wrap insulation and Prodex share few similarities. They both serve as a radiant and vapor barrier.
Aluminium foils are used as vapour barriers since the 1970s. Aluminium foil can be used as a vapour barrier and also as a vapour retarder, for example when perforated aluminium foil is used.
A Radiant Barrier and Vapor Barrier all in one. Controls condensation and prevents buildup of frost and condensation in colder climates.

Improper use of silver bubble wrap won't lead to any improvement in R-values, and could actually cause problems by creating areas of condensation and therefore moisture formation.
When it comes to foil insulation, it's generally recommended to leave an air gap of at least 25mm (1 inch) between the foil layer and the surface it's installed on.
It is generally more expensive due to being a metal-based product. It is also important to note that in order for foil insulation to work correctly, it must be kept free of any dust. This means in some areas, such as roofs, it may require being cleaned of dust from time to time to ensure maximum efficiency.
Materials such as rigid foam insulation, reinforced plastics, aluminum, and stainless steel are relatively resistant to water vapor diffusion. These types of vapor retarders are usually mechanically fastened and sealed at the joints.
Faced insulation includes a paper vapor retarder.
This is especially useful in humid locations, like coastal cities. It should also be noted that some faced insulation uses vinyl or even light aluminum foil as a vapor barrier, in place of paper.
ii) Extruded polystyrene
If joints are sealed properly, it can perform as an air barrier and, at certain thicknesses, may perform as a vapour barrier. Low permeability means that it does not absorb or pass on moisture, making it suitable for below-grade applications.
This is because foil works differently. Foil does not work by preventing the conduction of heat as other insulators do. It works by reflecting radiative heat back towards the source. So it drives your heat back into your home…and not out through itself and into the ether.
Vapor barriers—sheets of plastic or kraft paper—keep water vapor out of the wall cavity, so the insulation stays dry. Not every type of insulation needs a vapor barrier. But if it does, the barrier should face inside in northern, heating climates, and outside in humid southern climates.
Foil insulation can prevent radiant heat loss all year round. In summer, it can prevent heat from entering by reflecting sunlight. In winter, it can reflect heat back inside a room, keeping it warmer.
Bubble wraps serve as a good insulator because of its design which has small air pockets. Because the base material for bubble wraps are plastic, it heats up quickly, and so bubble wraps serve as good insulators. Bubble wraps are also best suited for greenhouses.
As an alternative to insulating shades, bubble wrap provides a pocket of air to prevent cold and heat from moving in and out of your home.
Bubble wrap, foam boards and fiberglass can help insulate a shed according to experts. Here's how to DIY. Insulate a shed and you can better regulate the temperature inside. It's a great idea if it doubles as a workshop, making it more comfortable for you to use both in cold weather and hot.
Is DuPont Tyvek a vapor barrier? No, DuPont Tyvek is not a vapor barrier. It is breathable, allowing moisture vapor to pass through it.
Not every wall does. A vapor retarder is a material used to prevent water vapor from diffusing into the wall, ceiling or floor during the cold winter. Whether or not you need a vapor retarder hinges on three main factors your climate, your home and the location of the wall you're insulating.
“Without a vapor barrier, concrete will deteriorate much faster through water vapor intrusion which degrades the quality of the concrete over time and can lead to foundation and building failures, like Surfside Condominium Collapse in Miami, Florida,” says vapor barrier plastic sheeting expert and Americover account ...
Black barriers are more effective at stopping moisture evaporation, compared with the clear barrier. The black color hinders the growth of plant seeds that may reside beneath a home's crawlspace. Plants naturally send moisture into the air, creating more moisture.
No, you don't need a vapor retarder, Class I or otherwise. By the time you paint the drywall, though, you've brought it into the Class III vapor retarder range (between 1 and 10 perms), and even less water vapor will diffuse through.
Results: It was found that the aluminum foil and cotton were the best insulators for keeping the water cold while the Styrofoam sheets and the bubble wrap were the worst two insulators for keeping the water cold.
The reflective side of the board should be oriented to the exterior and the nonreflective white side should be oriented to the interior. EXCEPTION: If vinyl siding is to be installed over AP™ Foil-Faced sheathing, install foam boards with the white nonreflective side toward the vinyl siding.
This might surprise you, but radiant barrier foil on its own has no R-Value! This is important to understand because radiant barrier does not take the place of traditional insulation (fiberglass, cellulose, etc.). Traditional attic insulation has R-value; this works to slow conductive heat.
