Everlast makes composite siding and trim from a proprietary blend of inorganic minerals and polymer resins, topped with UV-resistant acrylic capstock. The brand operates under Chelsea Building Products and has earned a reputation for premium composite siding that outlasts traditional materials.
The core advantage: siding that resists rot, warping, pests, and environmental damage better than vinyl, wood, or fiber cement. Their Standard Lap Siding weighs about 60% less than comparable fiber cement boards while delivering specific performance data contractors can use.
Core Product Lines and Performance Specs
Everlast’s Standard Lap Siding delivers measurable performance advantages:
| Specification | Value | Test Standard |
|---|---|---|
| Static wind load capacity | 68 psf with screws / 51 psf with nails | (manufacturer) |
| Water absorption | < 2.0% | ASTM D-570 |
| Heat shrinkage | 0.1% at 160°F | (manufacturer) |
| Coefficient of linear expansion | 8.38 x 10⁻⁶ in/in/°F | (manufacturer) |
| Weight per 12ft plank | ~7.8-7.9 lbs | (manufacturer) |
| Plank thickness | 0.225 in (±0.015 in) | (manufacturer) |
The low water absorption rate contributes significantly to longevity and freeze-thaw resistance. That 8.38 x 10⁻⁶ expansion coefficient means minimal movement in Montana’s temperature swings.
The Board & Batten line offers an 11-inch reveal with integrated batten design. No separate batten strips to install. Their Premium Color-Matched Trim System uses the same CedarTouch grain-embossed texture to match the siding perfectly.
Trim specifications that matter for installation:
| Component | Dimensions | Critical Detail |
|---|---|---|
| 3-1/2” Lineal | 12’ 6” lengths | Standard width trim |
| J-Channel pocket | Min 3/4” width | For siding termination |
| Pocket depth | 5/8” (<24 ft runs) / 3/4” (≥24 ft runs) | Allows for expansion |
| Installation temp | 0°F minimum | Cold-weather compatible |
Fire safety ratings include Class CC1 (ASTM D635) and Flame Spread Index < 75 (ASTM E84 Class B). Won’t support combustion.
Who Should Consider Everlast
Contractors favor Everlast for its lightweight handling and moisture resistance. Projects where long-term durability matters most benefit from these performance characteristics.
Engineered to last 30+ years with proper care extending lifespan up to 50 years. The lifetime warranty covers termite damage, color change, rust, and corrosion — confidence in material performance.
Water-impervious design eliminates common failure points: no rot, bow, warp, or swell. The EZNail hammer guide and EZStack system enable one-person installation — real labor savings on larger projects.
The composite material’s stability and minimal maintenance requirements make it suitable for owners planning to hold properties long-term. UV-resistant acrylic capstock delivers fade resistance that matters at Montana elevations.
The real differentiator: < 2.0% water absorption. In freeze-thaw country, that spec alone changes the conversation about siding longevity. Traditional materials trap moisture. Everlast doesn’t.
Frequently Asked Questions
Q: How does Everlast siding handle moisture compared to fiber cement?
Everlast composite siding has less than 2.0% water absorption (ASTM D-570), making it virtually impervious to moisture. This low absorption rate prevents the rot, warping, and freeze-thaw damage that affects other siding materials in wet or cold climates.
Q: What’s the actual weight difference between Everlast and Hardie board?
Everlast’s 12-foot plank weighs approximately 7.8-7.9 pounds, making it about 60% lighter than comparable fiber cement boards. This weight reduction translates to easier handling, faster installation, and less stress on wall structures.
Q: Can Everlast siding be installed in freezing temperatures?
Yes, Everlast siding can be installed at temperatures as low as 0°F, unlike some competing products that require warmer installation conditions. The material’s coefficient of linear expansion (8.38 x 10⁻⁶ in/in/°F) provides minimal movement even in extreme temperature swings.
Q: What wind loads can Everlast siding withstand?
Everlast’s Standard Lap Siding handles static wind loads of 68 psf when installed with screws or 51 psf with nails. These ratings provide adequate protection for most residential applications, including areas with moderate wind exposure.
Q: Does Everlast siding require painting or maintenance?
No, Everlast siding never requires painting or caulking at seams thanks to its UV-resistant acrylic capstock and color-through design. The siding maintains its appearance with only occasional washing and comes with a lifetime warranty covering color change and fading.
Q: What trim options work with Everlast siding?
Everlast offers Premium Color-Matched Trim in multiple widths (1-1/2”, 1-3/4”, 3-1/2”) with the same CedarTouch texture as the siding. The trim includes J-channel applications with minimum 3/4” pocket width for proper siding termination and expansion allowance.
