Masonite Cheyenne Smooth Molded Door

The Cheyenne delivers what matters in Montana construction — solid core options that provide 70% better sound dampening than hollow core, molded composite construction that resists warping, shrinking, and cracking, and a smooth primed surface ready to match any interior paint scheme. At standard thicknesses of 1-3/8 inch for interior doors or 1-3/4 inch for fire-rated and solid core versions, contractors get a door that handles Montana’s humidity swings better than natural wood while meeting multi-family fire code requirements.

Core Options Drive Performance

Three core options — hollow, solid, and fiberglass — make the Cheyenne adaptable to different project demands. The hollow core keeps costs down for basic bedroom and closet applications where sound transmission doesn’t matter. Step up to the solid core (engineered composite/MDF) when acoustics count — master bedrooms, home offices, bathrooms adjacent to living spaces. That 70% improvement in sound dampening translates to real privacy.

Fire ratings expand the Cheyenne’s reach into multi-family and commercial work. Available ratings include 20, 45, 60, and 90-minute options, all in the thicker 1-3/4 inch configuration. Montana’s growing multi-family housing market demands these ratings for unit-to-unit separations and egress corridors.

Core Type	Thickness	Best Application
Hollow Core	1-3/8”	Budget bedrooms, closets
Solid Core (MDF)	1-3/4”	Master suites, offices, bathrooms
Fire-Rated	1-3/4”	Multi-family, commercial

Sizing and Installation Requirements

Masonite builds the Cheyenne in the sizes contractors actually use. Standard widths run from 18 to 36 inches in common increments: 18, 24, 28, 30, 32, and 36 inches. Heights come in standard 80-inch and tall 96-inch options. The 96-inch doors solve the modern ceiling height problem without custom ordering.

Installation stays simple with standard hardware compatibility. The doors work with standard 3.5 inch hinges and accept standard locksets with either 2-3/8 inch or 2-3/4 inch backsets. For pre-hung installations, 4-9/16 inch flat jambs are available.

Field modification has limits. Maximum trimming allowance is 1/4 inch on sides and bottom — trimming over 1/4 inch voids the warranty. That’s tight tolerance for a molded door, but it preserves the structural integrity of the engineered core.

Bottom Line for Montana Contractors

The Cheyenne works because it solves real problems. The molded composite construction provides better stability than natural wood in varying humidity — critical when Montana homes swing from bone-dry forced air heat in January to open-window humidity in July. The smooth surface takes paint uniformly without the grain telegraphing common in wood doors.

For multi-family developers, those fire ratings up to 90 minutes check the code boxes. For custom home builders, the solid core option delivers actual acoustic performance, not marketing promises. Applications span from standard interior residential use in bedrooms and bathrooms to bifold configurations for pantries and laundry rooms.

Customer reviews run 2 to 4 stars depending on the retailer, with shipping damage being a common complaint. That’s a handling issue, not a product defect — molded doors need proper support during transport to prevent flexing damage.

The Cheyenne isn’t revolutionary. It’s a workhorse molded door that performs where it counts — dimensional stability, acoustic performance when you pay for solid core, and fire ratings that meet code. In a market flooded with hollow-core disposables, those fundamentals matter.

Frequently Asked Questions

Q: What sizes does the Masonite Cheyenne Smooth door come in?

The Masonite Cheyenne Smooth door comes in standard widths of 18, 24, 28, 30, 32, and 36 inches, with heights available in both 80 inches and 96 inches. The 96-inch option accommodates modern homes with taller ceilings without requiring custom orders.

Q: Can I trim a Masonite Cheyenne door to fit my opening?

Q: What’s the difference between hollow core and solid core Cheyenne doors?

The solid core Masonite Cheyenne provides 70% better sound dampening than the hollow core version, making it ideal for master bedrooms, bathrooms, and home offices where privacy matters. Solid core doors come in 1-3/4 inch thickness while standard hollow core doors are 1-3/8 inch thick.

Q: What fire ratings are available for the Masonite Cheyenne?

Q: How does the Masonite Cheyenne handle Montana’s climate swings?

The Masonite Cheyenne’s molded composite construction resists warping, shrinking, and cracking better than natural wood doors when exposed to varying humidity. This engineered stability makes it particularly suited for homes that experience dry forced-air heating in winter and higher humidity in summer.
