Barricade® Building Wrap is a high-performance air barrier that supplies continuous control of airflow over the entire building enclosure and can withstand damage during and after medical building construction.
A high-performance air barrier system is a vital component of medical building construction for achieving a healthy, durable, and energy-efficient structure with a tight building envelope. A high-performance air barrier system will also contribute towards stopping thermal bridging, increasing the effective R-value, and eliminating condensation within the wall systems of a medical building.
Essential elements of a high-performance air barrier system for medical buildings include code compliance, proper permeability, and the ability to control air and moisture infiltration.
The 2018 International Energy Conservation Code® (IECC®) Building Energy Codes and Standards determine minimum efficiency requirements for medical buildings, which assures reduced energy use and emissions over the medical building’s lifetime.
Moisture vapor permeability of a high-performance air barrier is essential to ensuring that the water that invades a wall system can escape. Water can get inside a wall assembly when rain leaks through the building envelope, through convection and conduction, and from the inside of the structure if the HVAC system does not effectively remove the moisture. Trapped moisture in a wall system is a problem because it can lead to mold, which is both unhealthy to the occupants of a medical building and can damage the integrity of the structure.
A high-performing air barrier system for medical construction resists air infiltration, and the moisture associated with it, into the wall assembly. Moisture can enter a wall assembly by thermal convection. Thermal convection occurs when warm air (which contains moisture) outside the wall assembly, is pulled towards the cooler air inside the wall assembly.
Stopping air-transported moisture from getting to the interior of a wall assembly is crucial because when the warm vapor touches the cooler interior walls, the vapor turns to liquid by condensation. A high-performance air barrier resists the flow of air and reduces, if not eliminates, moisture intrusion into the wall system by thermal convection.
Good durability in a high-performance air barrier is also critical to stopping air infiltration. Good durability resists damage or defects to the air barrier, either during or after installation, which will lessen its air-resistance performance. A high-performance air barrier has the strength to remain intact during and after medical building construction.
A high-performance air barrier controls unwanted heat gains and losses. Controlling heat flow is essential to a medical building’s energy efficiency and the comfort of the occupants. It is important that an air barrier lessens or restricts heat gains and losses through radiation, conduction, and convection.
Barricade Building Wrap is a high-performance air barrier that meets current codes and standards. Barricade Building Wrap is also an air- and water-resistant building barrier that stops air infiltration, prevents heat gains and losses, protects air quality, and maintains a medical building’s durability.
Barricade® Wrap provides the vital elements of a high-performance air barrier for medical building construction: code compliance, resistance to air and moisture infiltration, control over heat loss and gains, and assurance of a healthy and durable structure. Barricade house wraps supply continuous control of airflow over the entire building enclosure and withstands damage during and after construction.
