About Everlast

What is Everlast Advanced Composite Siding?

It's an entirely new category of siding that's taking the premium siding market by storm.  This is because of its remarkable durability in even 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 durability.

Extreme Fade Resistance and CedarTouch®

CedarTouch extreme fade resistanceThe face of Everlast products is made from a highly durable and fade-resistant acrylic layer that is chemically bonded to the substrate.

Then each Everlast plank or panel is embossed with Everlast's CedarTouch finish - the imprint of a rough sawn plank of real top-grade cedar. The result in the most authentic and UV-resistant siding on the market.

Impermeable. Resistant. Guaranteed.

Everlast Advanced Composite Siding is highly water resistant and impermeable to wood-boring insects. Guaranteed. You will never have to replace damaged boards or trim due to weather or insect damage like you would other materials. Moreover, thanks to Everlast’s advanced composite technology, your siding will never swell, bow, rot, expand, or contract – maintaining your home’s beautiful exterior, for life.

Minimal Maintenance Required.

Choosing Everlast means decades of virtually no maintenance for owners. An occasional light wash to remove any dust or dirt is all that's needed to help maintain Everlast's original luster. And unlike fiber cement or wood, Everlast does not need to be painted* or caulked, ever.

With Everlast, you can avoid common problems like these and keep your home's exterior beautiful, for life.

* Everlast can be painted, but it is not required and voids Everlast's warranty.

Easy installation. No special tools. Less than half the weight of fiber cement siding.

Everlast's lightweight construction and butt joint system allows for single-person, omni-directional installation that has a natural wood siding appearance. The composite material cuts just like wood, but without the dust, and our EZStack design assures that each panel seats firmly on the one below for a smooth, straight, and solid installation without requiring special tools.


Lifetime Warranty

Everlast has a best-in-category, Limited Lifetime Warranty to the original owner with a 100% replacement guarantee*.  Upon Ownership change, the warranty may be transferred to the new owner(s) as  a Fifty (50) Year Prorated Warranty.

*Warrants against excessive color change, peeling, flaking, cracking, rusting, blistering, and corroding.
