AZDEL Composite Panels

Azdel Composite Panels have been used in RV exterior and interior sidewall, ceilings, and roofs since 2006. They are produced using a 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.

Proven Technology Used to Replace Wood Since 2006

With twice the insulation value, excellent strength, and half the weight of wood, composite panels increase durability and lighten your adventure. Reduced weight helps keep fuel costs down, while superior insulation decreases heating and cooling costs. The panels also absorb sound waves to help provide a quieter ride, reducing road and outside noise.

Half the Weight of Wood Yet Twice as Strong.

Half the Weight of Wood.

Azdel composite panels are lightweight yet durable. Half the weight of wood - just think of the fuel savings!                                                

Odorless, Formaledehyde, Mold, Mildew Free

Azdel composite panels do not grow mold, mildew or emit toxic fumes, so you can breathe easily with peace of mind. Conversely, wood panels can decompose releasing airborne particle pollutants.

Water Resistant - No Delamination

Water Resistant - No Delamination, No Rot

Water will not cause fiber decomposition on our composite panels, so there is no rot or warping. Wet/dry cycles can affect wood bonds and diminish structural support.

Temperature & Humidity Changes are Tolerated

Temperature & Humidity Changes are Tolerated

Azdel composite panels are not damaged from freezing and thawing cycles, a common cause of delamination. Temperature and humidity changes are well tolerated.

Sound and Energy Absorbing

Sound and Energy Absorbing

Azdel panels are porous which allows them to absorb sound waves instead of being transferred through vibration of wood panels. You are in for a quieter ride.

Puncture and Impact Resistant

Puncture and Impact Resistant

Azdel composite panels are durable and stay strong. No adhesive failure from fluctuating temperatures can occur to weaken bonds.

Water and Wood Don't Mix

Take a look at what can happen to a traditional RV when leaks occur. Rotting, warping and delamination are common, commonly with a bubbling sidewall. This can cause thousand of dollars to repair. 

What is Lauan?

The term lauan (or luan) comes from the lauan tree, native to the Philippines and other Southeast Asian countries. Sometimes referred to as Philippine Mahogany or Meranti, it is the general name given to a wide variety of related woods imported from the Philippine Islands, Malaysia and Indonesia. Of all the hardwoods, Philippine lauan was once the most plentiful. It is not an actual mahogany. This is a trade name for underlayment plywood. 

What's inside your RV walls? Wood and water don't mix.

Soak Test

We placed an Azdel composite panel and a panel made from lauan in water for 51 days. The damage to the lauan panel displayed mold and the beginning of delamination which would require repair. The Azdel panel was 100% unaffected. Some RV's 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.

What does delamination look like inside the wall of your travel trailer, fifth wheel or motorhome?

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.

When you purchase your next RV, do some research about the construction. If you want an RV that will last, and provide you with the comfort and durability you deserve, be sure it has AZDEL Onboard!

What can you do to protect your RV from delamination?
Regular maintenance performed on your roof seals, around windows, slide-outs and more help to prevent water from seeping in. There are plenty of blogs, RV forums and websites out there that will advise you on how to purchase a used RV while avoiding an existing issue. Purchasing an RV with AZDEL Onboard is your best bet in avoiding this issue and the costly repairs and other concerns that come with it.

Quartzsite, AZ - January, 2019
Team AZDEL was onsite for the week of the huge RV show. Our first visit to Quartzsite allowed us to share our important message with thousands who turned out for the massive event. Among those was Jared Gillis of the YouTube channel All About RV's. He’d heard about Azdel composite panels but stopped by our exhibitor booth to check out the material up close. Here's what he had to say.

Lance Camper

Gary Conley goes into detail about why Lance Camper uses Azdel. It is 50% lighter than wood, won't rot or get moldy and improves insulation "R" value. Azdel also has no formaldehyde making it safer than other materials. It assists in sound deadening.

RV Water Damage & Mold Removal
"As we cut into the walls we notice they are stamped with formaldehyde warnings. Formaldehyde is a chemical used to produce wood products - especially in pre-manufactured homes and RV's. Exposure to formaldehyde can cause health problems, mostly respiratory issues. Of course this information was unnerving - the RV is our home. Good news: We found a product that can be applied to walls, floors, etc. that stops formaldehyde off-gassing. In a future video, we'll show you how we combated the problem of formaldehyde in our RV to ensure the air we're breathing isn't a toxic hazard."

Air Quality - How Indoor Particle Pollutants Can Affect Your Family's Health

Mold, mildew, and toxic chemicals are examples of particle pollutants that accumulate in confined spaces with temperature fluctuations when moisture is present. We have safety measures to protect us from smoke. We have carbon monoxide detectors to protect us from the odorless gas that we can’t see, but can kill, and propane detectors to detect leaks that can put your family members at risk. These are common standards or options in most RV's manufactured today.

But, what about the mold, mildew and toxic chemicals? How do we protect ourselves from these, and why does it matter?

It matters because these pollutants can affect our health in serious ways. RV's that are closed for weeks or months without ventilation are particularly susceptible to mold formation that can become airborne.

Delamination or separation of layers in a material reduces its strength. Adhesive failure can also occur when wood is exposed to water and temperature variations resulting in wet/dry cycles. Hot temperatures release formaldehyde in adhesives as they break down. Exposure to moisture can cause rot, warping, mold and mildew. This process causing sidewall bubbling is best known for the high cost repairs. This process can also have an adverse effect on your family’s health by contaminating the air you breathe. 
Mold can cause allergic reactions in asthmatics, and anyone, with or without allergies, may experience irritation of the eyes, skin, nose, throat and lungs when exposed to airborne mold particles. Chronic obstructive pulmonary disease, or COPD, is a common lung disease that includes bronchitis and emphysema, and the fourth leading cause of death in the United States. Avoiding pollutants, including smoking, chemicals, mold, dust, and fumes are recommended by the American Lung Association to avoid exacerbation of symptoms. 
Using a water-resistant composite material substitute for plywood is one way to avoid this exposure, and is a common sense move the RV industry is already making as families are demanding more healthy alternatives in RV construction.
Composite materials made by Hanwha Azdel can be used in place of plywood. There is no natural fiber decomposition, so they do not warp or rot, thus they don’t emit mold, mildew or toxic chemicals into your ventilation system that can cause harmful effects to your lungs and overall cardiovascular system. 
Additional benefits include less fuel costs due to reduced weight, less heating and cooling costs due to increased insulation value and a quieter ride with less road and outside noise. You will find your RV is less affected by temperature and humidity changes and damage from freezing and thawing. This increases the life of your RV by avoiding delamination which causes sidewall bubbling and can be quite costly to repair. Add the benefit of using an eco-friendly, sustainable product that does not impact the rain forest and you realize the absolute value of composite materials.
