Doors are hot sellers for remodeling

lltITH MORE and more homeUU owners choosing to update the appearance of their home as well as save energy by replacing exterior doors, a retailer should be sure that his staff is familiar with the latest developments in doors.

Doors have become entryway systems with energy-saving performance standards. This move, according to John W. Shoemaker, executive v.p. of the National Woodwork Manufacturers Association which represents the wood window and door industry, is asignificantimprovement. "With these two developments, homeowners who prefer wood entryways can benefit from a traditional product that incorporates today's new system approach and from the toughest standards of performance the wood door industry has ever set," he says.

The system approach means that doors are no longer viewed as a unit but as a system including frame, threshold, and weatherstripping whether the door is of wood or a man made material such as steel. Because many of the systems can now be set into place, so to speak, the do-ityourselfer has become more at ease with the installation and the old fears of hanging a door have been eased.

In addition to mastering the individual characteristics of the various entryway systems by using the manufacturer's literature and publications such as "A Guide to Energy-Saving Dobrs," a salesperson must be able to answer questions about performance standards. Independent laboratory tests have shown that more energy is lost around a door than through it. According to test results, heat loss through a door accounted for only 1.40/o of the total heating load, while 590 was lost around the perimeter of a door lacking good weatherstripping.

ITHOUCH the market for win- dows in new houses is static, the market for new windows in old houses is ecstatic.

Industry sources estimate the dollar volume in window replacements will reach $4.5 billion this year. There is little doubt that rapidly rising energy bills are inspiring many homeowners to replace worn out windows and add insulation, but, says the National Woodwork Manufacturers Association, there are other reasons for the surge in window replacements.

Good looks, ease of operation, increased comfort and new innovations by window manufacturers combine to encourage homeowners to update their homes with new look windows. Bay or bow windows, roof windows, garden windows and patio doors can give a house a new look.

Low maintenance is another reason for replacing windows. Many new wood windows have an exterior cladding that all but eliminates the need for periodic painting. Other styles are designed so that both sides wash from the inside. Others have optional grilles that snap in and out to give a traditional multi-paned look without the problem of cleaning individual panes.

Manufacturers are definitely new window concepts.

Andersen, for example, has created Concept IV as a way of looking at windows not as isolated units that emit light and air to a home, but as a system of interrelated components which, when properly designed, can offer beauty and fuel conservation. Using these principles, an additional room or space added to ahome is able to heat and cool itself, and even reduce the total amount of heating
