Fiberglass Windows Are Durable

Fiberglass windows are an excellent replacement option because of its intrinsic strength and durability. Of all of the window replacement materials that you could choose to put in your Seattle home, fiberglass windows will last the longest.

Fiberglass Windows Are Energy Efficiency

It’s get cold here in the PNW and sometimes it gets really warm. Either circumstance creates great demand on heating and A/C systems. Weather changes increase energy bills and cost you more to maintain a comfortable home. Fiberglass window replacement is an excellent way to improve energy efficiency.

Fiberglass Windows Are Heat & Moisture Resistant 

In the PNW it is wet. We experience lots of moisture and in the Summer it can get very warm and dry. For windows to last as long as possible you will want windows resistant to moisture and heat stress. Fiberglass windows are resistant to both moisture and heat stress.

Window Style Versatility

Some window frames don’t allow for specific design or looks. Fiberglass windows offer a wide range of styles, including wood clad finishes.

Fiberglass Windows Are Easy To Paint

Updating a house or paint color is common. If you like to update frequently, or know that you will at some point, then you’ll like Fiberglass windows. They are easy to paint.

Environmentally Friendly

In the PNW we care about being eco-friendly and responsible. Fiberglass windows are environmentally friendly. In addition to their energy-efficient thermal performance, fiberglass windows are manufactured using highly sustainable materials (like sand), arguably making fiberglass one of the greenest window choices available.
