Similarly, aluminum declined over the last two years and is currently at 7.4 percent of the total residential-type market. Vinyl penetration continued to increase to 66.9 percent of the total market, displacing both wood and aluminum.
Other framing materials, primarily fiberglass and composites, now account for 4.9 percent of the total residential market, compared to 4.5 percent of the residential market in 2009.
For the future, sales of wood and wood-clad residential window products are expected to continue their climb out of the 2011 low point, with 8.8 million units forecast for 2013, 10.2 million for 2014 and 10.8 million units in 2015.
Parsing the numbers differently, this time by type of construction, the report shows that wood and clad wood residential window products for new construction have edged up from 2.5 to 2.6 million units from 2009 to 2011, while maintaining a 22 percent market share. Meanwhile, sales for remodeling and replacement have contracted from 6.1 million units in 2009 (representing a 46 percent market share) to 5.1 million units and a 40 percent share. Aluminum products trended about the same, with the lost ground taken up by vinyl and other materials, including composites.
The vast majority of wood windows utilize Ponderosa pine. Fir/hemlock has seen the greatest increase in market share. Other softwoods were utilized in smaller shops throughout the United States. There is also a niche market for other specialty hardwoods, but it remains a fractional segment of the market.
Of the 540,000 non-clad wood windows, it is estimated that 82 percent are sold with a primed/prefinished exterior finish. The remainder are provided with no finish or a clear-coat/stain (natural finish).
Insulated glass usage is estimated at nearly 99 percent penetration, and warm edge spacer technology makes up 97 percent of the insulated wood window market. Eighty-four percent of wood windows are sold with low-E glass (vs 74 percent in 2009), with total units increasing slightly. Of these, sputtered coatings comprise a commanding 97 percent.
Wood windows continue to hold an approximate market share of around 20 percent across new construction and remodeling and replacement sectors as the pace of vinyl penetration levels off. Composite products, although not as yet separated statistically as a category beyond that of “other,” continue to make modest but steady inroads, with the category gaining in share from a projected 1.8 percent in 2011 to 2.2 percent in 2015.
