TWINWALL BASE SHEET (Extreme-Duty Corrugated Plastic Underbelly Material)
Corrugated plastic sheeting (referred to in the industry as twinwall, Coroplast, Polyflute, Corriflute, Proplex, etc.) is an extruded plastic sheet made of a high-impact polypropylene resin. The construction of this sheet makes it resistant to water, oils, and many chemicals that you will encounter while you are out there on the road. It works as an excellent insulating material on the base of the framework to keep heat/cold in, and the harsh elements out. It's lightweight construction makes it easy to cut and install. This material is static dissipative, heat resistant, and helps with sound dampening in your RV.
POLYETHYLENE UNDERBELLY MATERIAL
One of the standard materials used as the base protectant for RV underbellies since the 1980s has been the highly-flexible underbelly material. It has a flex-weave backing on an ultra-durable plastic tarp surface. It's resistance to harsh environmental conditions such as wind, water, frost, frigid temperatures, and extreme heat are why it has become an industry mainstay.
RECPRO MULTI-USE METALLIC RV BUBBLE INSULATION
While this is not an underbelly covering, this insulation is definitely in the mix. While applying underbelly to your rig, you need to have a solid insulator in-between the materials to help as a vapor barrier and keep out rain, heat, cold, and other problematic elements. This material is the same used by professional race teams, and it should go hand-in-hand with your underbelly installation.
FOIL TAPE
Our foil tape is the same used by the construction and automotive industries. This tape is highly adhesive and will bond to most surfaces once applied. The tight bond creates a solid vapor and watertight barrier that will keep your RV (home or other application) in good operating condition for years to come. Highly compatible with RecPro Metallic RV Bubble Insulation.
POLYETHYLENE UNDERBELLY TAPE
This tape has many uses across your home and RV applications. Durable, weather resistant, and backed by a cross-weave (making it resistant to tearing and stretching) this tape is made to work with our underbelly material for a complete covering of your underbelly.
