Construction and Materials
Benjamin Obdyke offers a range of high-performance housewraps designed to protect buildings from the elements while allowing moisture vapor to escape. These products are engineered to create a continuous air and weather barrier, contributing to a more comfortable and energy-efficient interior environment.
Construction and Materials
The core construction of Benjamin Obdyke housewraps typically involves a woven or non-woven fabric substrate that is then coated or laminated with specialized materials. The specific composition varies by product line to address different performance requirements and installation preferences.
- Woven Polypropylene: Many of their housewraps utilize a strong, tear-resistant woven polypropylene fabric as the base. This material provides structural integrity and durability during installation and throughout the life of the building.
- Microporous Coatings: A key component is the application of microporous coatings. These coatings are engineered with microscopic pores that are large enough to allow water vapor (like humidity from inside the house) to pass through, but small enough to prevent liquid water (rain, snowmelt) from entering. This breathability is crucial for preventing moisture buildup within the wall cavity, which can lead to mold and rot.
- Lamination: Some products incorporate laminating processes to bond different layers together, enhancing their barrier properties and overall performance.
