Answers To Frequently Asked Questions
Fiberglass offers many of the damage-resistant and insulation properties of vinyl. Aluminum frames do not insulate as well and tend to promote condensation problems. But if you like the appearance of aluminum, or your homeowner’s association requires it, we offer aluminum frames with thermal insulating strips that help suppress condensation.
While wooden frames insulate well, they are subject to cracking, peeling, insect damage and rot. Many of today’s wood-framed windows are wrapped in colored vinyl or aluminum for protection against damage.
Glossary of Window Terms
Argon: the nontoxic inert gas that is injected as insulation between panes of window glass to reduce heat transfer. Argon insulates more effectively than air between glass panes.
Aluminum-Clad: window framing made using a wooden core that is wrapped within protective painted aluminum layers for improved weather resistance.

Lintel: the upper horizontal support of a doorway.
Low-E: the designation for low-emittance glass, which has a coating that reduces radiant heat gain. While solar screens reduce light as well as heat transmission, low-E glass allows most visible light to pass through.
