Windows & Energy Savings

A building's windows can account for up to 40% of its heat loss and gain. There are three primary factors to consider when thinking about your building's energy conservation: Air infiltration; Radiant heat loss/gain; and heat loss/gain through conduction. All three factors can be reduced dramatically using The Window Man's Mon-Ray secondary glazing windows.

Some of The Window Man's Mon-Ray Secondary Glazing projects in the Metro DC area include

Why Windows & Doors Cost So Much

Justice Clarence Thomas recently asked me why windows and doors cost so much. The answer is:

...Windows are some of only a few parts of your home that impact both the inside and outside of it.
...Windows have to look good and look appropriate to your home as they attract the eye from inside and out and they add curb appeal.
...Windows must also perform! Let light inside, allow fresh air in "ventilation" and at the same time be able to stop air infiltration, stop radiant heat loss & gain and reduce fading. All while keeping a slim profile (most window sash are less than 1/4 as thick as walls) and of course they are not allowed to let in any water!

They must do all of this while looking good! We should give them female names--a lot of multitasking while looking good!!
