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.

About Everlast - <none>

Extreme Fade Resistance and CedarTouch Finish®

The face of Everlast products is made from a highly durable and fade-resistant acrylic colorant 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.


Virtually Water Impermeable and Insect Resistant.

Unlike fiber cement, wood, and engineered wood, Everlast siding is virtually impervious to water - siding's enemy #1. This means your Everlast siding will never swell, bow, split, or rot. It's what makes Everlast suitable for any locale, including those with harsh freeze/thaw seasons.

Plus, wood and engineered wood siding are vulnerable to wood-boring insects, requiring costly and recurring pest control. Everlast siding’s all inorganic composition helps to eliminate this problem.

Contractors love Everlast too.

There are no special tools required. Everlast siding is less than half the weight of fiber cement and produces no harmful dust when cut. Everlast Lap Siding’s EZStack joinery ensures a speedy and level installation and  planks install left to right or vice versa. And one-piece Everlast Board & Batten, with an integral batten, speeds installation. Everlast installs with virtually any pocketed trim package and flashing at seams is not required. Plus, there’s no caulking or painting, ever.


Near Zero Maintenance

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. 

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

True Peace of Mind.

With Everlast, homeowners experience the ultimate peace of mind knowing their siding will look just as beautiful as the day it was installed, year after year, decade after decade.
