Less Energy Means Less Money

Insulation is the most effective way to improve a home or building’s energy efficiency. “Insulation” refers to the resistance of heat flow. Insulation board helps keep heat in during the winter and helps keep heat out during the summer.

Enhanced R-Value: POLYCORE 5000

R.L. Adams Plastics is pleased to announce our latest product innovation – POLYCORE 5000 with an improved R-value….R2.5.  The increased R-value offers more opportunities in the residing and new residential markets.

POLYCORE 5000 is a ½” x 4’ x 24’ bundle (equivalent to three 4’ x 8’ sheets) and can be carried by one contractor over their shoulder verses the cumbersome movement when trying to carry just one 4’ x 8’ sheet typically found in today’s market. This product also does not contain fire retardants.

We expect contractors will find many benefits for using POLYCORE 5000 for their residing and new residential projects.

POLYCORE 5000 R2.5 is only available in gray colored foam.

RL Adams Plastics Introduces House Wrap Alternative

Why do typical Building and House Wraps have to be made from flimsy, paper-like materials? Why does installation have to be a hassle? Why can’t typical house wraps offer the contractor and homeowner more than simply being a paper-thin “barrier”?POLYCORE Building Wrap

RL Adams Plastics continues to change the conversation with innovative ways of improving outdated products and techniques.  We are introducing POLYCORE Building Wrap, part of the new Adams Home Barrier System. POLYCORE Building Wrap offers the benefits of a premium house wrap, and enhances it with more strength, 1.0 R-value, gasket formation around doors and windows, and single-person installation. POLYCORE Building Wrap lays flat and won’t tear and flap in the wind.  It doesn’t require the added time, money, and hassle of bringing in an additional sub-contractor to install.
