How to Identify a High Quality Window
August 1, 2026
There are countless options available when you’re in the market for new windows. Whether you’re building a new home or upgrading your current one, choosing the right windows is an important investment. With so many products, styles, and performance features to consider, the process can quickly become overwhelming.
To help make your decision easier, we’ve outlined a few key areas to focus on when evaluating the quality of a window.
The Frame
The frame is the structural foundation of any window. It surrounds and supports the entire window system, making it a critical component of performance, durability, and energy efficiency.
At Access Windows & Doors, our windows feature a 6-chamber frame design, which provides exceptional thermal insulation. This advanced construction helps reduce heat transfer and improve overall energy efficiency. Our windows achieve U-values as low as 0.13. A U-value measures the rate at which heat passes through a window. The lower the U-value, the better the window performs at keeping heat inside during the winter and outside during the summer.
The Glass
A window’s glass does far more than provide a view. It plays a major role in your home’s comfort, efficiency, and energy performance. With a variety of glazing options available, it’s important to understand what you’re getting. Our windows are built with triple-pane glass, double Low-E soft coatings, and double argon gas fills for superior thermal performance.
Low-E (low emissivity) glass is specially coated to reflect infrared heat while still allowing natural light to pass through. This technology helps keep your home cooler during the summer months and warmer throughout the winter, reducing the demand on your heating and cooling systems.
The Profile
The window profile contributes significantly to both structural performance and thermal efficiency. All Access windows are built using the RAU-FIPRO profile core, an advanced composite material that delivers outstanding stability and torsional rigidity. This allows for the construction of larger window units without relying on traditional steel reinforcements, which can create thermal bridges and reduce energy efficiency. When steel reinforcement isn’t required, GPS foam chamber inserts can be incorporated to further minimize heat loss and enhance overall window performance.

Installation
Even the highest-quality window can underperform if it isn’t installed correctly. Proper installation is essential to ensuring your windows operate as intended and provide long-term performance. A poorly installed window can lead to a variety of issues, including drafts, water leaks, reduced energy efficiency, and premature wear. For example, if a window is not installed perfectly level, it may not open and close properly. If it isn’t sealed correctly, moisture and air infiltration can occur, potentially leading to costly damage over time. That’s why it’s important to work with experienced, qualified installers. Speak with your window consultant about recommended installation professionals to ensure the job is done right the first time.

Making the Right Choice
Ultimately, the decision comes down to finding the window style, features, and manufacturer that best suit your home and your goals. Windows are often one of the largest investments homeowners make, so taking the time to research your options is well worth the effort. Understanding the frame, glass, profile, and installation process will help you make a confident and informed decision.
