Owens Corning PINKWRAP® is a high-performance, weather-resistant air barrier designed to protect exterior walls from wind-driven rain and air infiltration while still allowing moisture vapor to escape the wall cavity. Engineered for durability, it offers excellent tear resistance, cold-weather flexibility, and extended UV exposure ratings—up to 180 days for Premium and 90 days for Classic. Lightweight and easy to install, its distinctive semi-translucent pink color allows for accurate fastening and clean, efficient installation on the job site. 

We’ve recently switched to Grip-Rite ProWrap™-SA because it offers several key advantages over Vycor enV-S, making it a superior choice for high-performance wall assemblies—especially in demanding conditions. With a permeability rating exceeding 60 perms, ProWrap™-SA allows significantly more moisture vapor to escape the wall cavity than Vycor enV-S, reducing the risk of trapped moisture and mold. Its 5-layer synthetic construction and high-tack butyl adhesive create a durable, self-sealing air and water barrier that installs easily without primer, even in temperatures as low as 20°F. Compared to Vycor’s lower perm rating, shorter UV window, and more labor-intensive installation, Grip-Rite ProWrap-SA stands out as the better solution for high-humidity climates, cold-weather installs, and projects where breathability, ease of installation, and extended exposure time truly matter.

Since 2014, Formerly DelPrete Home Improvements has proudly used Low-E Housewrap as a superior alternative to traditional fan-fold or Styrofoam-backed vinyl siding. This decision was driven not only by performance, but by safety and environmental responsibility—unlike other insulations, Low-E is not highly flammable and is far more eco-friendly. Its insulative, reflective barrier wraps the home in year-round energy efficiency, and when paired with a premium moisture barrier like CertainTeed Vycor enV-S, it delivers unmatched protection, comfort, and long-term savings for homeowners.
