WEATHERBOARDS FIBER CEMENT SIDING MANUFACTURER: CERTAINTEED
F
iber cement has proven its stability and durability over the past 10 years or so. Now that companies such as CertainTeed have the attention of the marketplace, they’re constantly adding design options that will broaden the appeal of this durable, storm-resis- tant, insect-proof product. CertainTeed’s brand of FiberCement siding has
an added green aspect. The product incorporates fl y ash in its mix. That makes the siding lighter in weight than other brands, and easier to work with—with- out losing the qualities that make cement-based siding a good green choice. One often unsung aspect of these products is the reduced painting require- ments. Acrylic paint has a very high embodied energy, so siding products such as Weatherboards, which require less frequent painting, have additional environ- mental benefi ts.

FIBER CEMENT EDGES CLOSER TO VINYL Although installations of vinyl siding continue to dominate the retrofit market, the cost of cementitious siding is now almost on a par with PVC. Will vinyl eventually lose its market dominance?

ULTRA SERIES FIBERGLASS WINDOWS MANUFACTURER: MILGARD
U
ltra Series fi berglass replacement windows from Milgard off er a durable alternative to PVC windows. Why is a fi berglass frame superior to vinyl (PVC)? First, because produc- tion of virgin PVC has a high energy cost and has been shown to produce dangerous
pollutants. Second, while PVC expands and contracts dramatically with temperatures, fi ber- glass responds similarly to the insulated glass. This creates less stress on seals, potentially extending window life. In addition, the windows are custom made for each project, so you always get an exact fi t, reducing the chance of unwanted air infi ltration. Milgard off ers the windows pre-painted or you can paint them yourself on site. They come with a full lifetime
warranty.
