Composite siding has quickly become the leading siding choice for homeowners, specifically those who plan on being in their homes for more than 10 years. This is due to the very minimal maintenance required and extreme durability of composite, making the ROI (return on investment) the highest amongst all siding products. Everlast composite siding is the leading composite siding manufacturer. It is made from cellular PVC (polymer resins, inorganic materials, and acrylic colorants). Due to Everlast being a PVC product, it is virtually impervious to water and requires almost zero maintenance. It is essentially the same material as TREX deck boards, which are commonly known by most homeowners.
