Flex Trim’s Original polyurethane roof trim bends to a 6-inch minimum radius while maintaining waterproof performance across Montana’s extreme temperature swings. This flexible trim handles curved architectural features that would require expensive custom millwork in wood.
Montana contractors working on custom homes with curved rooflines, arched entries, or historic restorations get a product that won’t crack when temperatures drop from 85°F to -20°F between seasons. The high-density polyurethane polymer resin flexes with thermal expansion while staying completely waterproof.
Performance That Handles Montana Weather
Flex Trim’s polyurethane construction is waterproof, non-shrink, rot-proof, and weather-resistant. No wood trim delivers that combination. When spring snowmelt saturates everything, this trim won’t absorb moisture. When July UV beats down at 7,000 feet elevation, it won’t crack or warp.
The flexibility specs tell the real story:
| Specification | Value |
|---|---|
| Minimum radius | 6 inches for standard profiles |
| Standard length | 12 feet |
| Optional lengths | 5’, 8’, 10’, 11’ |
| Profile options | Over 50,000 profiles available |
| Fire resistance | Semi fire resistant |
That 6-inch radius capability solves real problems. Curved rake boards on custom homes. Arched entries that need consistent trim profiles. Round windows that would otherwise require pieced wood segments. The material is impervious to moisture, rot, and insects — critical advantages when carpenter ants and woodpeckers plague Montana homes.
Standard profiles range from 2-1/2” to 8” in boxed sets, though individual profiles like 9/16” or 11/16” are available for matching existing millwork. With 50,000 profiles in the catalog, contractors can match virtually any historic trim profile without custom milling costs.
Installation That Saves Labor
The lightweight design makes handling easier than wood, especially on tall ladder work. Normal woodworking tools (saws, air guns, hand nails) handle the material without special blades or bits.
Critical installation points that matter:
- Paint or stain only after installation to prevent cracking of the finish during flexing
- Keep nails/screws to a minimum and away from edges to prevent ‘bumps’ or cracking
- Construction-grade adhesive (e.g., Flex Trim No-Nail Adhesive) is highly recommended
- Cut material slightly long and shave to exact length
Ships in compact 23” x 23” boxes, cutting freight costs to remote Montana job sites compared to shipping 12-foot wood trim. That box size fits in standard trucks and doesn’t require special handling.
The hardwood-like density and feel means it machines predictably. No fuzzing like foam products. No melting like some synthetics. Just clean cuts that take paint or stain like quality millwork.
Real-World Performance
Customer reviews average 4.4 stars across 19 reviews. One user noted it ‘bent easily and glued easily’ and looked great once primed and painted. Another described it as a ‘tremendous product’ that is very easy to cut.
The warranty covers 90 days against material and workmanship defects, with 30-day refund/replacement through major retailers. Not the longest warranty, but the material’s proven durability makes warranty claims rare.
All materials are VOC free, eliminating indoor air quality concerns during installation. May require specific fire-resistant coatings for certain government regulations, though most residential applications won’t face those requirements.
FAQs
Q: Can Flex Trim handle Montana’s temperature extremes without cracking?
A: The high-density polyurethane polymer resin is waterproof and non-shrink. Unlike wood that expands and contracts with moisture changes, this material stays stable through freeze-thaw cycles.
Q: How tight can I bend Flex Trim for arched applications?
A: Standard profiles bend to a 6-inch minimum radius. That handles most residential curved applications including arched windows, curved rake boards, and round columns.
Q: Will standard paints and stains work on Flex Trim?
A: Compatible with virtually all brands and types of wood stain and paint. Paint or stain only after installation to prevent cracking of the finish during flexing.
Q: How does Flex Trim compare to wood for exterior durability?
A: The material is waterproof, non-shrink, rot-proof, and weather-resistant. It’s impervious to moisture, rot, and insects. Wood can’t match those properties, especially in Montana’s climate.
