Alliance Door Products Lynden Door ELEMENTAL Collection - Grooved Primed Flush Doors

Factory-primed MDF doors with precision-grooved profiles for contractors who need paint-ready surfaces and fire ratings up to 90 minutes. Modern in style and construction, characterized by clean, simple lines offering a modern take on traditional wood and molded interior doors — minus the wood grain telegraphing through paint six months later.

The ELEMENTAL Collection delivers what matters: consistent groove positioning for hardware placement, wide rails that forgive field trimming, and fire ratings that satisfy commercial code requirements. Ten standard profiles available (1-Panel through 5-Panel configurations) mean contractors aren’t stuck with one look.

Core Construction and Fire Rating Options

20-minute standard (all sizes, Category A or B); optional 45-, 60-, and 90-minute ratings available (Category A). That flexibility matters when bidding mixed commercial projects — standard doors for tenant spaces, higher ratings for corridors and stairwells.

Core Type	Thickness Options	Fire Rating
Hollow Core	H8 (1-3/8”), H4 (1-3/4”)	20-minute standard
Solid Core / Particleboard Core	P8 (1-3/8”), P4 (1-3/4”)	20-minute standard
Fire-Rated Particleboard Core	P20 (1-3/4”, 20-minute rating)	Up to 90-minute available

The particleboard core options handle Montana’s temperature swings better than hollow core. Less expansion, less contraction, fewer callbacks about sticking doors when the humidity drops in January.

Groove Specifications and Field Modification

Groove dimensions: width approximately 0.22 inches, depth approximately 0.04 inches, profile bevel-grooved. That 45-degree bevel profile prevents paint pooling — critical detail that separates clean finishes from amateur hour.

Field modification specs that actually work:

• Up to 1 inch on each end (top and bottom) trimming allowance
• 10 inches (standard, meets most disability-access requirements) bottom rail
• 6 inches (easily accommodates standard door hardware) stile width

That 10-inch bottom rail handles ADA compliance without custom orders. The 6-inch stiles mean standard locksets fit without crowding the grooves. Consistent route positioning to accommodate most hardware locations — no measuring and remeasuring to avoid groove conflicts.

Size Range and Applications

Standard widths from 2’0” to 4’0” (standard); greater widths available by special order. Heights in 6’8”, 7’0”, 8’0”. The 8-foot option saves headaches on commercial projects where ceiling heights creep up.

Applications: Residential interiors (Single-family, multi-family, condos, apartments), Commercial spaces (Offices, hospitality, retail), Institutional settings (Education, healthcare), Mixed-use developments, ADA-compliant spaces requiring specific rail heights, Areas requiring fire-rated partitions.

The Optional VanAir Ventilated Door construction for improved airflow without grilles solves the mechanical closet problem — airflow without ugly louvers breaking up the clean lines. Available in bifold configurations for closets where swing clearance doesn’t exist.

Bottom Line

ELEMENTAL doors solve real problems: paint-ready surfaces that don’t telegraph grain, fire ratings that span from basic to corridor-rated, and dimensional tolerances that forgive field conditions. The groove positioning stays consistent across the line — set up your hardware jig once.

Factory-primed surface ensures a stable, high-quality paint finish. That matters in Montana where doors see 100-degree temperature swings annually. MDF substrate means no grain raise, no resin bleed, no surprises after painting.

For contractors handling multi-family or light commercial work, the combination of fire ratings, ADA-compliant dimensions, and field modification allowances makes these doors practical workhorses. Not the cheapest option. But doors that arrive ready to hang, trim, and paint without drama justify the upfront cost.

FAQ

What fire ratings are available for ELEMENTAL doors?

20-minute standard (all sizes, Category A or B); optional 45-, 60-, and 90-minute ratings available (Category A). Every door size can achieve the 20-minute minimum, with higher ratings available across the full range.

Can these doors be trimmed to fit?

Wide top and bottom rails allow for up to 1 inch of trimming on each end for field adjustment. That’s 2 inches total height reduction possible without compromising door integrity or warranty.

What makes the groove profile paint-friendly?

The 45° bevel profile combined with shallow 0.04 inch depth prevents paint from pooling in the grooves. Brush or spray application works equally well.

Do these doors meet ADA requirements?

10 inches (standard, meets most disability-access requirements) bottom rail height exceeds typical ADA minimums. No special ordering needed for compliant installations.

What’s the warranty coverage?

1-year limited warranty for the standard construction series. Specific series (CD Series - 5 years, LD Series - Lifetime) may apply depending on custom specifications.
