Glossy Gelcoat RV Fiberglass Siding

Using GRP(fiberglass reinforced plastic) as siding for RVs has become a trend in the RV building industry because of its lightweight, durable and aesthetic properties. RV fiberglass siding builds up the body along with other insulating core materials,providing users with a comfortable living space.

Multiple Excellent Performance in One

High Strength to Weight Ratio

GRP is strong but lightweight, which can greatly reduce the weight of the RV.

Impact Resistance

GRP can withstand great forces without breaking, making it durable.

Waterproof

GRP basically does not absorb water and is not easy to adhere to water, so the interior of the RV can maintain a dry environment even in rainy and snowy weather.

Corrosion Resistance

GRP is highly resistant to various chemicals and environmental factors, including moisture, salt water and various solvents, making the RV suitable for harsh environments.

Electrical Insulation

GRP is an excellent electrical insulator, which can reduce circuit safety issues such as leakage and short circuits in RVs.

Low Maintenance Cost

GRP is not easy to rust, corrode or degrade, reducing the need for regular maintenance and repairs.

Thermal Insulation

The thermal conductivity of GRP is very low, which can reduce heat transfer, making it far better than any metal material in thermal insulation.

Analysis of RV Fiberglass Siding

RV fiberglass siding is made of thermosetting resin (unsaturated polyester, epoxy, etc.) and fiberglass felt or fiberglass woven cloth in a certain proportion. A layer of gel coat is applied on its surface for protection and decoration.

Fiberglass Resin Mixed Layer

Different types of resin and fiberglass combinations, as well as different fiberglass to resin ratios, are important factors that affect the performance of RV siding.

Gelcoat Layer

Gel coat is a special coating material applied to the surface of fiberglass reinforced plastics, mainly used to provide a smooth appearance and protect the base composite material from environmental factors.

Non-woven Fabric Layer

Non-woven fabric can make the adhesive more evenly distributed, reduce waste, and make the glass fiber sheet and other core materials more firmly bonded together.

How to Improve the Performance of RV Fiberglass Siding

Anti-ultraviolet

Add anti-aging agents to improve the weather resistance of RV siding.

Flame Retardant

Add high-performance flame retardants to improve the fire resistance of the RV siding.

Reinforcement Treatment

Add silica, calcium carbonate, etc. to enhance the mechanical properties and wear resistance of the siding.


Surface Treatment

The fiberglass siding for RVs can be presented in different colors and patterns. Users can choose their own style in the RAL color series, and there are a variety of textures for reference. Of course, you can also provide the designed pattern texture for us to complete the final production.
