We have been busy doing quite a few window replacements for clients this year. Many of the windows are in older homes. We have found that Marvin windows work very well for most of these installations. We can get the windows sized just right and they offer many options that retain the feel of the older homes.
Today we are working in a 1920’s home replacing the double hung window units. Once the window sashes have been removed we remove the cast iron counter weights and fill the weight pockets with insulation. In most cases we use an expanding foam insulation that fills the entire weight pocket void. You can see the pale yellow foam insulation peeking out from the weight pocket in the picture. By doing this we are able to retain the interior and exterior casing trims. This is an excellent way to upgrade windows and gain energy efficiency.
