Kolbe & Kolbe Millwork offers vinyl windows. The Wausau, Wis.based, high-end wood window manufacturer will supply a Vinyl wide selection of vinyl window designs - radius, bow, bay and geometric - through its new KVW Windows & Doors division. The new line includes double hung models, sliders, casements, awnings and sliding doors. A new production plant, located in Manawa, Wis., was scheduled to begin operating in February.

Numerous glass options and grids are available. 800-542-9118. www.simonton.com. Circle 182.

It''s clear that energy savings alone won''t justify window replacement (see "Other Considerations in Window Replacement"). If windows are to be replaced in any Replacement case, however, the analysis provides justification for an upgrade to high-performance glass. At a cost Windows of $60 per window, the payback on low-e argon filled Vinyl glass is a reasonable Comparison 9 years.And there are other issues to be considered. Replacement The companion study on window condition estimated the current value of deferred maintenance at over $1 million, which reduces the comparative cost of window replacement. Comfort and other effects may be difficult Windows to quantify in dollar terms, but they have important costs and benefits. Energy saving is just Vinyl one factor to be weighed in this complex and expensive decision.Energy savings resulting directly Comparison from window replacement Replacement is Windows just one of many things to consider in deciding whether and when to undertake a major window replacement project. Several Vinyl other important Comparison factors are discussed Replacement and Windows below. We performed a total of about 100 simulations, estimating energy use for the six test case residences modeled with the current windows and Vinyl with each of five replacement options. Comparison Thirty McLean Gardens residents responded to our request for a waiver to access utility records, and we checked our simulation results for the existing-windows case against these bills, tweaking some of our assumptions as a result. We also did some basic sensitivity runs to evaluate the effect of orientation and shading.The results brought Replacement some Windows and Vinyl surprises (see Figure 3 for typical results for one apartment type). The first is the large projected heating savings for the storms-only replacement, an option with a far lower cost than full window replacement. This results from the combined effects of Comparison reduced infiltration and the estimated reduction in U-value attributable to a tighter system.
