Energy Code Compliant Windows Montgomery County MD: What to Look For

Why Energy Code Compliance Matters Before You Buy

• Ask whether the proposed glass package fits the orientation of the openings.
• Check whether the frame design will fit the existing opening without unnecessary alterations.
• Review whether the product is approved for the type of home you own, especially if the property is historic or in an HOA.
