Everlast Standard Lap Siding

Everlast Standard Lap Siding solves the moisture trap problem that traditional fiber cement can’t touch. At less than 2% water absorption (ASTM D-570), compared to fiber cement that absorbs water like a sponge, this composite siding handles Montana’s brutal freeze-thaw cycles without the cracking and deterioration that sends homeowners scrambling for repairs every decade.

The weight advantage changes the installation game entirely. At 7.8-7.9 pounds per 12-foot plank — approximately 60% lighter than comparable fiber-cement boards — contractors move faster, strain less, and don’t need a crew of four to handle basic installations. That matters when you’re hanging siding in July heat or trying to beat an October freeze.

Installation Efficiency and Real-World Coverage

The standard dimensions deliver 6-7/8 inches of reveal exposure with planks available in 12-foot and 16-foot lengths. Each plank measures 8-9/32 inches in actual width with a consistent 0.225-inch thickness. No guessing games on coverage calculations.

Installation requires standard 16-inch or 24-inch on-center framing over a code-approved weather-resistive barrier. The fastening system uses corrosion-resistant fasteners through pre-punched nailing slots — head diameter 3/8” to 7/16”, shank diameter around 0.160”. Critical detail: don’t drive fasteners flush. Leave a 1/32-inch gap for thermal movement.

The real efficiency comes from what you don’t do. Unlike fiber cement, Everlast produces no harmful silica dust when cut. No special masks, no OSHA concerns, no cleanup nightmares. Just use a power saw with a fine-tooth blade (60+ teeth) and keep moving.

Performance Metrics That Matter

Specification	Value	Source
Water Absorption	< 2.0%	ASTM D-570
Heat Shrinkage	0.1% at 160°F	Tested
Static Wind Load (screws)	68 psf	ASTM D5206
Static Wind Load (nails)	51 psf	ASTM D5206
Flame Spread Index	< 75 (Class B)	ASTM E84
Self Ignition Temperature	430°C	ASTM D1929
Coefficient of Linear Expansion	8.38 x 10⁻⁶ in/in/°F	Tested

The 68 psf wind load capacity with screws handles Montana’s chinook winds and high-elevation gusts. The 0.1% heat shrinkage at 160°F means minimal movement even during those scorching August installations on south-facing walls.

For wildfire-prone areas, the Class B fire rating (flame spread index < 75) meets code requirements. The CC1 burning classification indicates no self-sustained burn — it won’t keep feeding a fire once the ignition source is removed.

Montana Climate Advantages

The freeze-thaw resistance sets Everlast apart in Montana conditions. With less than 2% water absorption and being impervious to moisture, the composite material doesn’t trap water that expands when frozen. Traditional fiber cement absorbs moisture, then cracks and delaminates through repeated freezing cycles.

The composite blend uses inorganic minerals and polymer resins with a UV-resistant acrylic capstock finish (CedarTouch technology). This UV-stable acrylic capstock prevents the fading and discoloring that hits standard vinyl siding hard at Montana’s elevations.

Installation temperature matters — don’t install below 0°F. Plan accordingly for shoulder-season work. Use seam brackets at all butt joints and maintain a 1/4-inch gap between plank ends and trim pockets for expansion.

The Trade-Offs

Contractors report higher upfront material and installation costs compared to vinyl. Fair enough. The material costs more because it performs better. The warranty specifically states that painting the siding voids coverage — this isn’t a product for homeowners who repaint every five years.

Color-matched premium PVC trim, corner boards, and J-channels are available, along with optional accessories including rigid PVC starter strips and Cortex hidden fastener systems. Seam brackets come with pre-loaded stainless steel screws — one less thing to source separately.

FAQ

How does Everlast handle Montana’s temperature swings?

The coefficient of linear expansion at 8.38 x 10⁻⁶ in/in/°F and heat shrinkage of only 0.1% at 160°F means minimal movement through temperature cycles. The material is specifically designed for freeze-thaw cycles.

What’s the real weight advantage over fiber cement?

A 12-foot Everlast plank weighs 7.8-7.9 pounds versus approximately 19.5 pounds for comparable fiber cement — that’s 60% lighter. Multiply that by hundreds of planks on a whole-house job.

Does it really never need painting?

The UV-stable acrylic capstock prevents fading and discoloring, and the siding is marketed as virtually maintenance-free, never requiring painting or caulking. The warranty explicitly voids coverage if you paint it.

How does it perform in high-wind areas?

Static wind load testing shows 68 psf capacity when installed with screws, 51 psf with nails. Use screws in high-wind zones for maximum holding power.

What about woodpecker damage?

The composite material resists wood-boring insects. Woodpeckers attack siding when hunting insects inside walls — this material doesn’t support insect colonies like wood products do.
