Low maintenance siding

Unsurpassed rigidity.

Charter Oak engineers have created a superior – and exclusive – design for Charter Oak that provides exceptional rigidity and resistance to high winds.

The unique TriBeam system gives Charter Oak superior rigidity, helping to ensure straight lines and even walls, on both new and existing homes. The result is a particularly beautiful installation with the strength to maintain an enduring appearance.

Coordinated trim options

When you’re creating an exterior design, the delight is in choosing the details. Siding color defines the total mass of your home; trim and accent details focus on particulars, highlighting those special features and characteristics that set your home apart.

We offer a wide selection of trim and accent products made to complement the beauty and colors of Charter Oak siding

Limited lifetime warranty

Charter Oak Siding comes with a lifetime limited warranty. Ask your Washington Energy Services representative for details.

  • Is Charter Oak vinyl siding an environmentally sound choice for my home?

    From its two simple and natural building blocks of salt and natural gas to its efficient manufacturing process and modest transportation energy use, vinyl siding has lower environmental impacts throughout its lifecycle, especially when compared to other exterior cladding. In the overall environmental impact by life cycle stage:

    Brick has nearly 5X the environmental impact of vinyl siding and nearly 4X the impact of insulated vinyl siding.
    Fiber cement has nearly 3X the environmental impact of vinyl siding and more than 2X the environmental impact of insulated vinyl siding.

    With a strong commitment to environmental stewardship, Alside vinyl siding helps promote resource efficiency – virtually no manufacturing waste, fuel-efficient transport, minimal installation scrap and safe to install. It’s a smart choice for you and a positive choice for the environment.

All for home.
