Insulation Systems and Vapor Retarders

April MCN Product Catalog - Vapor Retarders

The rFoil reflective insulation is a layer of polyethylene bubbles bonded to and sandwiched between a metalized foil facing and a white polyethylene sheet. It is specifically designed to control heat gain or loss, and prevent interior condensation, in all types of metal and metal-clad buildings.

Reef Industries
Reef Industries offers a complete system of polyethylene vapor retarders, seaming tapes and pipe boots for total moisture infiltration control. Several levels of permeance products are available to meet project demands for roofing, wall and under slab applications. Griffolyn vapor retarders can be manufactured in sizes to meet project requirements.

Designed to be applied over unfaced fiber glass insulation, loose-fill applications and spray foam, MemBrain looks similar to typical polyethylene sheeting, but is actually a polyamide-based material that gives MemBrain its unique ability to adapt its permeability depending on the climatic conditions. With a high resistance to water vapor in winter or low humidity, MemBrain behaves like a moisture vapor retarder such as poly sheeting.
