Charter Oak® is one beautiful soffit panel. But its real beauty lies beneath the surface with its revolutionary TriBeam™ Design.

Thanks to TriBeam, Charter Oak is the most rigid vinyl soffit on the market. It spans uneven surfaces and delivers an exceptionally even course line while resisting sagging and twisting over long runs. Charter Oak soffit is an attractive, low-maintenance option for porch ceilings, large overhangs, or anywhere you want to create high impact visual appeal. For eaves, specify Charter Oak ventilated soffit paneling. Aeration openings hidden inside the panel's grooves provide the air flow that reduces heat and humidity build-up in attics.

Charter Oak soffit’s gently rounded board edges and elegant 3-1/3” exposure width combine with hidden aeration openings to provide the premium appearance of expensive wood soffit. And its finely textured, low-gloss surface looks and feels like freshly applied paint. Plus, Charter Oak soffit is available in 21 colors that can be beautifully coordinated with all Alside siding, trim, and accent options.

Equally important, Alside backs Charter Oak Soffit with our Lifetime Limited Warranty* and over 50 years of leadership and innovation in the building products industry.
