Exterior window lintel
Exterior window lintel refers to a high-density polyurethane exterior header molding positioned over building window openings to establish refined architectural lines while shedding rainwater away from frame joints. Specified across exterior facade thermal insulation cladding projects as an ultra-light replacement for cast stone, precast concrete, or wood lintels, it imposes zero dead load on building envelopes. Extremely resistant to severe freeze-thaw weathering cycles, UV degradation, and driving rain.

What is the purpose of an exterior window lintel?
It closes the horizontal wall gap directly above window openings, enhancing aesthetic definition and deflecting rainwater runoff.
Are polyurethane window lintels resistant to severe exterior weather conditions?
Yes, high-density polyurethane is 100% weather-proof, UV-stable, and frost-resistant without rot or cracking.
