Windows and doors have been a part of the Frontier Building Supply story from the beginning. With growth and the proliferation of choices within the industry, we realized that it was time to focus on specialization both in the products we offer and in their presentation. With multiple showrooms for vinyl and wood windows, fiberglass composite, steel and wood doors our Millwork Center puts everything under one roof. Staffed by a highly trained group of experienced millworks pros, the Millworks Center offers every service need by today’s busy contractor. 

Just like the ‘Energy Star’ rating labels seen on whitegoods, did you know that windows & doors now also come with an energy rating depending on how well they insulate your home from heat, sun glare and noise?

At Frontier Building Supply, we customize a solution to ensure you get only the windows and doors you need to suit your home, depending on sun, shade and even the climate of your location. 

Our sales consultants are trained to ensure you achieve comfort, noise reduction, safety and other benefits, while also achieving a cost-effective, budget-friendly solution. By choosing a product with a higher star rating, you will save money on energy bills over the life of your windows and doors, while being kind to the environment.

We offer the latest in computer sided design and have a wide selection of brand name doors and windows to choose from.

All of our stores have displays of the latest window and door designs but be sure to visit our Millworks Center for the most complete selection and most displays of the latest designs in doors and windows from many quality manufacturers.
