Product Summary
Cedar Breather® is the solution for preserving the beauty and life of wood roofing. As an underlayment for wood shingles and shakes, Cedar Breather provides space for a continuous airflow between the solid roof deck and the shingles. Benjamin Obdyke's patented three-dimensional design allows the entire underside of the shingle to dry, eliminating excess moisture, preventing thermal cupping and warping, and reducing potential rotting.
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.
- Perm Rating: The materials and construction are carefully controlled to achieve specific vapor permeability (perm) ratings. Higher perm ratings indicate greater breathability. Benjamin Obdyke offers products with a range of perm ratings to suit various climate conditions and building codes.
- UV Resistance: The materials are often treated or formulated to provide a degree of UV resistance, allowing the housewrap to withstand exposure to sunlight for a specified period during construction before cladding is installed.
- Adhesion Properties: The surface of the housewrap is designed to promote excellent adhesion of tapes and sealants used for detailing joints, penetrations, and laps, ensuring a continuous and effective air and weather barrier.
Product Lines and Features
Benjamin Obdyke provides several distinct product lines, each with specific features tailored for different applications:
- Hydrogap®: This line features a patented drainage gap technology. The housewrap itself has a textured surface that creates a space between the wrap and the cladding, allowing bulk water to drain away more effectively. This is particularly beneficial in areas prone to high rainfall or for cladding systems that may trap moisture.
- Membrane Technologies: Other product lines may focus on advanced membrane technologies that offer exceptional strength, water resistance, and air barrier continuity. These often utilize advanced polymers and manufacturing techniques.
- High Permeability Options: For climates where rapid drying is essential, Benjamin Obdyke offers housewraps with very high perm ratings, ensuring efficient vapor diffusion.
- Tear Strength: Engineered for durability on the job site, these housewraps are designed to resist tearing from wind, impacts, and fasteners.
The primary function of these materials is to serve as a critical component of the building envelope, working in conjunction with other materials to create a dry, durable, and energy-efficient structure.
