One sided radiant barrier may be attached to insulating materials, such as polyisocyanurate, rigid foam, bubble insulation, or oriented strand board (OSB). Reflective tape can be adhered to strips of radiant barrier to make it a contiguous vapor barrier or, alternatively, radiant barrier can be perforated for vapor transmittance.
OSB is easily identifiable by its characteristic wood strands. Oriented strand board ( OSB ) is a type of engineered wood , formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations.
Louisiana-Pacific Corporation (LP) is an American building materials manufacturer. The company was founded in 1973 and LP pioneered the U.S. production of oriented strand board (OSB) panels. [1] Currently based in Nashville, Tennessee, LP is the world's largest producer of OSB and manufactures engineered wood building products. [2]
The energy conserving property has been defined as thermal emittance (the ability of a surface to release radiant energy that it has absorbed). Those coatings qualified as Interior Radiation Control Coatings must show a thermal emittance of 0.25 or less. This means that an IRCCS will block 75% or more of the radiant heat transfer. These low "E ...
The function of a vapor barrier is to retard the migration of water vapor. A vapor barrier is not typically intended to retard the migration of air. This is the function of air barriers. [8] Air is mixed with water vapor. When air moves from location to location due to an air pressure difference, the vapor moves with it.
According to environmental NGO Arnika, Kronospan's production site in the town of Jihlava, Czech Republic, is the No. 2 source of environmental pollution in the country overall, topping the list of released formaldehyde (2018 increase of 3 tons vs. previous year [11]) and just 2nd to Spolana Neratovice in the released amount of mutagenis substances.
Radiator reflector panels being installed behind a domestic radiator. A radiator reflector is a thin sheet or foil applied to the wall behind, and closely spaced from, a domestic heating radiator.
Air barrier components – Pre-manufactured elements such as windows, doors and service elements that are installed in the environmental separator and sealed by air barrier accessories and which have an air leakage rate no greater than 0.20 L/(s•m 2) at a pressure difference of 75 Pa when tested in accordance with ASTM E 2357.
