Dennyfoil Vapor Barrier
From $6.00
Dennyfoil Vapor barrier saves energy and reduce fuel costs. Quick, easy application to all types of walls, floors, roofs, and ceilings makes it ideal for residential and commercial use. Dennyfoil Vapor barrier cuts mildew and dampness, reduces inner wall condensation, and retards combustion.
Not only does it meet all FHA requirements for vapor protection, but it is also recommended by environmental physicians and consultants for use by chemically sensitive people to seal off fumes, odors, gases, and chemicals.

A vapor barrier is any material used for damp proofing, typically a plastic or foil sheet, that resists diffusion of moisture through the wall, floor, ceiling, or roof assemblies of buildings to prevent interstitial condensation and of packaging.
Vapor diffusion retarders are normally available as coatings or membranes. The membranes are technically flexible and thin materials, but sometime includes thicker sheet materials named as “structural” vapor diffusion retarders. The vapor diffusion retarders varies from all kinds of materials and keep updating every day, some of them nowadays even combined the functions of other building materials.
Aluminium foil is widely used for radiation shield (barrier and reflectivity), heat exchangers (heat conduction) and cable liners (barrier and electrical conductivity). Aluminium foil’s heat conductive qualities make it a common accessory in hookah smoking: a sheet of perforated aluminium foil is frequently placed between the coal and the tobacco, allowing the tobacco to be heated without coming into direct contact with the burning coal.
Electromagnetic shielding
The shielding effectiveness of aluminium foil depends upon the type of incident field (electric, magnetic, or plane wave), the thickness of the foil, and the frequency (which determines the skin depth). Shielding effectiveness is usually broken down into a reflection loss (the energy bounces off the shield rather than penetrates it) and an absorption loss (the energy is dissipated within the shield).
