Advanced Composite Siding

Advanced Material Science

Everlast truly lasts for life. Alternatives fade and deteriorate over time, but Everlast’s innovative triple-composite process yields the most advancing siding material in the industry. The face of this product is made from highly durable and a fade-resistant acrylic layer that is chemically bonded to the substrate.

Taking The Market By Storm

Everlast Siding holds remarkable durability even in the harshest climates and no maintenance requirement – apart from an occasional washing. Unlike other solid siding products, Everlast’s unique combination of inorganic minerals, polymer resins, and acrylic colorants produces a thick, solid and strong siding with unsurpassed quality.

Guaranteed Impermeable

Everlast Siding will never swell, bow, rot, expand or contract. You will never have to replace damaged boards or time due to weather or insect damage like you would other materials, as it is highly water resistant and impermeable to wood-boring insects.


Features and Benefits

  • Industry-best lifetime warranty
  • No scraping, caulking or painting
  • Authentic look and feel of real cedar siding for life
  • No cracking, chipping, rotting, or wood-boring insects
  • Easy installation – no special tools, less than half the weight of fiber cement
