Prevent Air & Moisture Transmission with AIR-SHIELD ™ LSR by W. R. MEADOWS

W. R. MEADOWS, celebrating its 90th year as a construction leader, continues to push its building envelope product line – including its AIR-SHIELD LSR.

Air-Shield LSR

AIR-SHIELD LSR is an eco-friendly, asphalt-free, single-component, synthetic rubber based liquid air/vapor and liquid moisture barrier. It acts as an air/vapor and liquid moisture barrier within the building envelope and can be applied to most common surfaces and integrated into various wall systems of both new construction and restoration.

“Not only is AIR-SHIELD LSR environmentally friendly, but it is user friendly as well,” said Russ Snow, Building Science Specialist of W. R. MEADOWS. “Its sprayable application allows for simple, safe application, and easy cleanup.”

W. R. MEADOWS has published very specific instructions for spraying AIR-SHIELD LSR. These sprayer application guidelines can be found on our website as well as in PDF format for downloading or sharing purposes.

If you have any questions during your application, or if your project has a special set of circumstances that contradict those outlined in our sprayer guidelines, please contact our Technical Services team for assistance.

AIR-SHIELD LSR is available in 5 gallon pails or 55 gallon drums. Free samples and literature of AIR-SHIELD LSR are also available by request.
