Vapour Barriers WHAT IS CONDENSATION? The air around us holds moisture in the form of a colourless vapour; the warmer the air, the greater the amount of moisture it can hold. If the air is cooled, then it cannot hold as much moisture and there comes a point at which the water changes from a vapour to a liquid, which we see in the form of “condensate”. SOURCES OF MOISTURE IN A BUILDING Construction Moisture From the very start of a building’s life, moisture associated with construction such as wet concrete and plaster can take months or even years to dry completely. Building Occupancy The...

Vapour Barriers Unreinforced vapour barriers are manufactured by extruding a continuous layer of polyethylene to make a single layer membrane. Many of the performance characteristics of such membranes are directly related to the thickness of the material used, therefore to get a higher vapour resistance, tensile strength, puncture resistance etc. you need to use a thicker membrane. As the membrane becomes thicker, they become less flexible which can then lead to installation and detailing issues. A major issue with unreinforced vapour barriers is their tendency to puncture if snagged on a...

Vapour Barriers PROCHECK® 125 Procheck 125 is a lightweight reinforced polyethylene vapour barrier which can be utilised in a variety of commercial applications. It can be utilised where very high moisture vapour resistance is not a necessity but a strong, durable airtight membrane is. Key Features • Thickness 0.35mm • 350 micron • Tensile MD = 190 N/50mm CD = 130 N/50mm • Nail tear 150 N / 190 N Advantages • Improved airtightness • Reinforced • Translucent • ow / Medium Risk Applications eg. L infrastructure, light commercial buildings PROCHECK® FR200 Procheck FR200 is used as a fire...

Vapour Barriers Key Features • Thickness 0.3mm • Tensile MD = 230 N/50mm CD = 130 N/50mm • Nail tear 100 N / 125 N Advantages • Improved airtightness • Reinforced • Translucent • Unaffected by Chlorine • Low Risk Applications eg. Warehouses, Infrastructure, Light/Medium Commercial Buildings Procheck 300 is a lightweight, reinforced, polyethylene, vapor barrier for use within roof and wall constructions to prevent warm, moist air entering the building fabric and condensing within the insulation. The woven, polypropylene, multifilament scrim reinforcement provides good resistance to tears and...

Impermeable outer layers restrict passage of moisture in both vapour and liquid form Reinforcement prevents tearing for enhanced durability Airtight structure limits air leakage and convective heat transfer Vapour Barriers PROFOIL 861 Profoil 861 is a heavyweight, reinforced vapour barrier with an aluminium foil core to give a high water vapour resistance. The aluminium foil is protected on both faces by polyethylene for corrosive situations such as chlorine in swimming pools. Key Features • Thickness 0.4mm • Tensile MD = 290 N/50mm CD = 190 N/50mm • Nail Tear 130 N / 140 N Advantages •...

Procheck A2, is a fire resistant, vapour and airtight membrane. Procheck A2, with its’ Class A2-s1,d0 fire classification to BS EN 13501-1, is considered non-combustible with no contribution to fire. Its composition comprises of the glass fibre backing, with a pure aluminium foil and clear lacquer coating. Key Features • Roll size 1.5m x 50m • Tensile MD = 700 N/50mm CD = 400 N/50mm • Nail Tear 170 N / 130 N Advantages • Fire resistant to A2,s1-d0 • Water vapour diffusion tight • Reflective material, emissivity <0.05 • Easy to install • Clear lacquered aluminium surface allows for low...
