Superior Rigidity.

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.
