The Dark Side

White and beige always will be the most popular siding hues, but vinyl siding manufacturers are adding deeper shades to their collections as color technologies improve.

According to Mark Axelrod, director of marketing for Crane, newer ASA (acrylonitrile/styrene/acrylate) formulations and other acrylic polymers and resins allow siding makers to create darker colors that are more resistant to UV rays. Crane, for instance, recently introduced Cypress green to its palette.

Allen Duck, marketing manager for Heartland, claims that the new formulations, like Headland's Composite Technology program, not only offer better color retention, but greater heat resistance so that the siding won't distort.

Nevertheless, darker colors aren't for every home. Replacement contractor Eric Feldt Sr. says he only offers a handful of dark hues because his clients prefer lighter shades.

Plus, says Larry Etman, a Fairfax, Va.-based remodeler, strict homeowner association regulations often dictate color options, and many of the rules require pale colors.

What's more, Feldt hesitates to install dark tones because he worries that in 10 years they might not be as vibrant--despite comprehensive warranties offered by most siding makers.

"Manufacturers don't have time-tested proven products yet," he cautions.--S.H.
