LP ExpertFinish Desert Stone siding delivers what Montana contractors actually need — 16-foot lengths that slash seam count and 45% lighter weight than fiber cement that means one person can handle installation. At 0.354 inches thick, 7.84 inches wide, and 16 feet long, each board covers approximately 9.33 square feet with standard 1-inch overlap.
The ExpertFinish factory-applied Desert Stone color comes with a 15-year limited finish warranty, while the substrate itself carries a 5/50 year limited warranty — 5 years full coverage plus 50 years prorated. Most telling for Montana weather: the warranty includes hail damage coverage.
What Makes the 16-Foot Length Matter
Longer boards reduce the number of seams on a wall by up to 33% compared to standard 12-foot siding. Fewer seams mean fewer places for moisture infiltration, less caulking maintenance, and cleaner wall lines. For contractors billing by the square, those missing seams translate directly to labor savings.
The weight advantage compounds with length. At approximately 45% lighter than fiber cement siding and weighing just approximately 15.56 lbs per piece, crews can work faster without the fatigue that comes from wrestling heavy boards all day. One-person installation is often possible — try that with 16-foot fiber cement.
Installation Without the Silica Circus
Standard woodworking tools handle the job — circular saw, miter saw, nail gun, drill. No specialized silica-safety equipment required. That’s a real advantage over fiber cement, which demands diamond blades and serious dust control to meet OSHA silica standards.
The installation specs keep it simple. 3/16-inch gap required at all vertical and horizontal joints to allow for expansion/contraction. Blind-nailing is recommended with fastener heads covered by the overlap. Use 8d siding nails with a minimum 1.5-inch penetration into studs. All field-cut ends must be sealed with touch-up paint or high-quality sealant.
Weather Resistance That Matters
The SmartGuard process uses zinc borate, resins, and waxes to provide deep-seated resistance to fungal decay, termites, and moisture. More relevant for Montana contractors: engineered to withstand impact from hail, rocks, and airborne debris better than traditional wood or vinyl.
This isn’t theoretical durability. LP SmartSide is free of knots, voids, and defects common in natural wood and engineered to resist twisting, warping, and shrinking. The material maintains dimensional stability through Montana’s freeze-thaw cycles better than solid wood ever could.

The Bottom Line
LP ExpertFinish Desert Stone siding solves real jobsite problems. The 16-foot lengths cut installation time. The light weight saves backs. The impact resistance handles Montana hail. At 45% lighter than fiber cement with better impact resistance and no silica hassles, it earns consideration for any lap siding project where efficiency matters.
The product remains relatively new to market with sparse reviews for the Desert Stone color specifically, though the LP SmartSide line generally receives 4.5+ star ratings for durability and aesthetic appeal. For contractors tired of fiber cement’s weight and dust, or traditional wood’s maintenance demands, this engineered alternative delivers measurable advantages.
