Vapour Barrier (27)
Choose from many types of vapour barriers for residential and commercial structures. Aluminium foil barriers prevent moisture penetration so that insulation and other parts of structures can last longer. The shiny aluminium foil also reflects radiant heat and maximizes cold retention, helping to keep houses cooler in the summer. In winter, the foil maximizes heat retention, helping to minimize heating costs while keeping the interiors warmer. Aluminium is a robust material that resists corrosion, shrinking, and tears. To maximize energy loss, look for reflective insulation. These foils last for a long time while providing a reliable barrier on floors, attics, subfloors, ceilings, and basement floors. The material is also easy to cut to size for a convenient and neat installation.
Other types of vapour insulation include polyethylene rolls. These come in various thicknesses and help reduce the amount of sound transference. Clear polyethylene options have some insulation capabilities. Other options feature a higher level of vapour impermeability for residential, commercial, and industrial applications. Polyethylene barriers are suitable for use under concrete slabs and in foundations. Some are suitable for external walls and ceilings and are easy to size and install. Aluminium and polyethylene vapour barriers meet several requirements set by the Canadian Standards Boardcode (CSB) as well as ASTM standards for different construction applications.
Rolls of building vapour barriers are available in different sizes. Compact options can cover up to 400 square feet. These are ideal for small renovation and construction projects. Medium-size rolls have sheets that cover between 400 and 1,000 square feet. For large residential and commercial projects, consider rolls that cover over 1,000 square feet. Aluminium and polyethylene building vapour barriers are reliable because of their water resistance. They resist the growth of mould, bacteria, and mildew so that structures remain strong without rotting. The lighter weight of these materials is convenient because it means users can protect walls and structures from vapour without increasing structural load.
