Windows & Doors

New windows and doors can add value to your home as well as improve its energy efficiency, comfort and curb appeal. Windows and doors are an important part of the thermal boundary of your home. Units designed to offer higher energy performance for your home means higher efficiency, lower bills, and natural light that doesn’t add heat. There are many manufactures and styles of windows such as double hung, casement, sliding, awning, Argon filled, Low E glass, tinted glass, double and triple glass and on and on. We can help you choose the right window or door to maximize your investment and reap the most benefits.

New windows, doors, or skylights should be Energy Star rated. These products are independently tested by the National Fenestration Rating Council (NFRC) and have strict energy efficiency guidelines. Performance criteria should be matched to our climate zone here in Maryland, which is North Central, as some windows and doors are better at keeping you warm while others excel at keeping you cool. Ratings to pay attention to are U Factor,  SHGC, and AL.

U Factor tells how well the window insulates. The lower the U Factor the greater a window’s resistance to heat flow and better it’s insulating properties.

SHGC (Solar Heat Gain Coefficient) is how much solar radiation from the sun is transmitted directly and/or absorbed and released inside the home as heat. The lower the SHGC Rating, the less solar heat it transmits and the greater it’s shading ability.

AL is the units Air Leakage rating. The lower the rating the tighter the unit is.

Installing your new windows or doors correctly is imperative. The best product in the world is only as good as the installation. Here at High Performance Home we use our own in-house crew to ensure your new windows or doors perform as great as they will look!
