Exterior Crown Moulding
Polyurethane exterior crown moulding cornices serve as architectural transition profiles installed underneath roof eaves and between building stories. Engineered to define facade contours while resisting rain infiltration, these high-density polyurethane profiles deliver complete protection against rain, snow, sub-zero freeze cycles, and intense UV exposure. Outperforming expanded polystyrene (EPS) alternatives, rigid polyurethane resists surface damage, crumble, and cracking over decades. Light mass avoids facade load expansion.
Frequently Asked Questions
Is polyurethane exterior crown moulding water-resistant?
Yes, due to its closed-cell polymer structure, polyurethane absorbs zero water, preventing rot, mildew, and swelling.
How is exterior crown moulding installed?
It is secured directly onto exterior wall surfaces using high-tack polyurethane construction adhesive backed by mechanical screws or anchors.
