At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

Windows questions, answered by experts

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Awning windows are just like hopper windows except that they open the opposite way. Instead of opening inward, awning windows open outward with a hinge at the top. This creates a mini-awning within your window frame, which is where the name comes from. Hopper windows, on the other hand, open inward with a hinge at the bottom.

You should avoid abrasive materials when cleaning windows, including scrubbing pads that can scratch the glass and harsh chemical cleaners that have alcohol or ammonia in them, as these can damage window treatments and frame materials. It’s best to use a clean microfiber cloth to clean glass and old black and white newspapers to dry it without leaving streaks.

There are several downsides to choosing casement windows for your home. Firstly, casement windows can cost significantly more than standard windows—especially if you need to install custom windows. If you plan on installing window AC units, then casement windows aren’t the best option, as it can be difficult to fit an AC unit into windows that open sideways or outwards. 

The hinges on casement windows also pose a higher risk for break-ins, as rust and wear and tear can make the hardware easier for burglars to break into.

Egress windows provide emergency exits, increase natural light, and improve basement ventilation.
