One of the most important variables to consider when choosing sunroom windows is how durable they are. It’s important that you choose windows that are strong and sturdy enough to hold up through different types of wear and tear throughout the year. Durable windows that can withstand rain, snow, hail, wind and excessive heat and cold weather will help to ensure their long-lasting efficacy.


If your sunroom windows need replacement, consider energy-efficient options. Choosing energy-efficient windows will not only keep your cooling and heating costs low, but it will maximize the comfort within your home, especially during winter months when outdated windows allow drafts to creep through. Our windows have low-E coatings and are made with multiple-glazed panes. One of their most important features is that they reduce up to 75% of UV light penetration, while letting natural light through. This is a key benefit for a room that typically experiences the most sunlight, like a sunroom.


Whether you’re looking to install windows for a newly built sunroom or simply need replacement windows for your existing sunroom, it’s important to consider the aesthetic value it will produce. Sunrooms typically have more than one wall of windows, making it visible to neighbors beside your home. While it’s important to choose windows that meet your vision and style, it’s nice to showcase the beauty of your home to inquisitive eyes. Windows from Cosello Construction will not only increase the appeal of your sunroom but will also raise the overall value of your home.

Here are three of the most popular styles of sunroom windows:

  • Sliding Windows – These windows are ideal for sunrooms, as they open horizontally, allowing you to utilize space more efficiently.
  • Bay and Bow Windows – These styles give your sunroom a more open and expansive view, which allows the room to get more sunlight.
  • Double-Hung Windows – This traditional style of window design moves up and down vertically. They are easy to clean and will likely flow with the rest of the windows in your home, as many homes are designed with this style of classic windows.

Don’t settle for anything less than the high-performing quality of our windows at Cosello Construction. If you live around Philadelphia, PA, Burlington, NJ, or Bucks, Mercer, and Camden Counties, contact us today to schedule an appointment for a free estimate!

Andrew and his team were amazing! The project took several days (demolish and rebuild a staircase and supporting wall). They were on time EVERY day and truly cared about my property. They hung plastic and ensured that the dirt/dust from the project did not permeate the rest of the house.

From the very beginning, Andrew Cosello was professional and knowledgeable. He gave us a fair and appropriate estimate for the job. He communicated well with us throughout the entire job – from informing us as to when the job would begin as well as updates about how long the job would take.

After receiving 7 quotes for the project, we hired Cosello Construction. Cosello’s quote was not the cheapest or the most expensive. We feel that we got what we paid for by hiring Cosello Construction: quality craftmanship, experience, and an industry professional. Cosello Construction worked with our architectural plans and completed the work masterfully.

Andrew and his assistants do excellent work. We had them do major renovations on our investment property, so we hired him for some minor work in our own home. We were very pleased with the work done on both properties and would recommend them to a friend or relative without hesitation.
