New Alternative to Window Replacement

Building owners typically consider replacing windows an obvious energy conservation measure and are surprised when an energy audit does not identify this renovation as a priority. While it is true that modern window technologies such as double-pane glass promise greater energy savings, the cost of quality window replacements is significant. This means other energy conservation measures provide a much better value.

Generally, the most cost effective way to reduce airflow and increase the efficiency of a building is to air seal and insulate. Air sealing creates barriers to airflow by covering cracks and openings in the building cavity. Adding insulation on top of air sealing will slow heat flow and increase the occupants comfort, as well as helping your space retain the air you have already paid to heat. Retrofitting to reduce air leakage can be completed at a fraction of the cost of new windows.

Introducing a New Alternative to Window Replacement – Signa System

Signa System is a method specifically designed for on-site conversion of single glazed windows to hermetically sealed insulating glass in high rise buildings, skyscrapers and other large or small architectural projects. Our windows are warrantied for 10 years.

A patented air spacer containing a moisture absorbing desiccant and heat welding technology allow us to provide an easy and clean installation with no need to vacate the premise for the work to be done.

This process has been developed in Denmark, by the founder and president of Signa System, Inc. Ryszard Borys and has been in commercial use since 1976.

If you are an architect, building owner, condominium owner and would like more information please review our site www.signasystem.net and do not hesitate to give us an email www.signasystem.net/contact/

If window replacement is still a renovation you want to pursue, be sure to consider these factors:
Replacement windows are not “maintenance free”

According to Michael Jackson, FAIA, chief architect of the Illinois Historic Preservation Agency pointed out, “maintenance free” means windows cannot be repaired. This truism is critically important when deciding whether to replace or restore. Vinyl, fiberglass and aluminum windows and insulated glass are formed using materials and techniques that are not in good standing with conservation practices.  Once they deform, fade, warp or fail in other ways, there is virtually nothing that can be done but turn to replacements, perpetuating a cycle that repeats every 20 years.

Environmental costs of window replacement

A poorly performing window that requires replacement after just a few years means additional debris in our landfills, resources extracted for production and energy for manufacturing and transport, none of which is sustainable. The materials that comprise many replacement windows – aluminum, vinyl and glass – are among the greediest in terms of energy consumption, resource depletion and inability to recycle. All leave a heavy environmental footprint.
