Winnebago Azdel Composite Fiberglass

Winnebago uses Azdel Composite Panels in its fiberglass manufacturing, an environmentally friendly and lightweight composite panel, in the construction of the sidewalls in Class A Gas, Class A Diesel and Class C motorhomes.


Azdel Composite Panels have been used in RV exterior and interior sidewall, ceilings, and roofs since 2006. The panels are manufactured using a cutting-edge, patented blend of polypropylene and fiberglass to create a strong, lightweight, quiet, weather and temperature resistant, odorless and environmentally friendly wall that will increase the life of your RV.Azdel Onboard Cutaway

With twice the insulation value, excellent strength and half the weight of wood, Azdel composite panels increase the durability and lighten the weight of your motorhome. Azdel’s reduced weight keeps fuel costs down while its superior insulation decreases heating and cooling costs as well as absorbs road and outside sound to provide a quieter ride.

Azdel compared its water resistance to luan, the underlayment plywood used in competitor RVs, and found that luan displayed mold and the beginning of delamination after 51 days of water exposure and the Azdel panel was 100% unaffected. Some RVs sit through six months of winter, subjected to freezing, thawing, heating and repeating the cycle with the potential for water seeping into the wall. This damage occurred in less than two months.

How does delamination affect your RV? Have you ever seen an RV with bubbling along the sidewalls that looks like an air bubble under contact paper? That’s delamination – the wood is separating from the outer layer and can no longer support the structure. Water seeping in has soaked the wood. This along with freezing, thawing and hot temperatures causes it to decompose and loosen adhesive bonds. Because of the moisture/water presence, mold and mildew are formed or accelerated during this process. What you don’t see can make all the difference – in the support structure of your walls, road noise, and comfort level inside your rig, the air quality your family breathes, and the longevity of your RV.
