STL Windows Direct Is Your Trusted St. Louis Windows Installer

The Sky’s the Limit for Your New Windows!

STL Windows Direct is a division of STL Design and Build. When we remodel kitchens, bathrooms and basements, window and door replacement is often part of the project. STL Windows Direct was born because we realized our customers wanted premium quality in an affordable window. In response, we created a better, more energy-efficient, longer-lasting window that is designed specifically for the St. Louis weather. Our exclusive windows are at a competitive price point and still offer a lifetime warranty and transferable  warranty!

STL stands for Sky’s the Limit, a daily reminder that we want to deliver STL service and quality. The STL venture was formed when two local St. Louis families – friends since college – joined forces. Our managing partner is a second-generation home builder, past director of the HBA and a Homer Awards Chairman.

Designed Specifically for the St. Louis Weather

Our Smart 365 Innovations windows are engineered for St. Louis weather, where we often experience two to three seasons in the same day, resulting in pressure on windows due to expansion and contraction. These custom-made windows are made, measured and designed to perfectly fit each opening.

Replacing all of your windows with STL Windows Direct can save you up to 35% on your energy bills, which means your windows will pay for themselves! The same person who measures the windows also installs them, which helps reduce errors. We buy our windows factory-direct so there’s no middleman, resulting in cost savings for you

Conservision

High Efficiency Windows Deserve High Efficiency Glass

---

THE BIGGEST AND BEST IN THE BUSINESS. PERIOD.

Conservision glass is designed and manufactured by the world’s largest and most experienced glass insulator. Our glass is assembled using two separate seals, one on the spacer and one on the back side of the spacer. Because of the research and design of the Conservision glass we can prove that the chance of ever having a seal failure is one quarter of one percent after 20 years. As a matter of fact, in a laboratory comparison of seal failures, Conservision glass will outperform the next largest selling insulated glass by over 400%

High Efficiency Insulated Glass System/Double Clarity & Triple Performance

• Triple Coated Silver Low-e Plus + Pane of Low Iron, Low-e(Clearer than clear glass)
• Center of glass only U-factor: 019(Triple pane clear is 0.39)
• Dual Sealed Strength Glass(Most windows use single strength to sav money.)
• Lifetime Seal Failure Warranty
• SGGC(Solar Heat Gain Coefficient)L 0.27(The lower the number the better of preventing the sun’s heat from entering during summer season).
• Stainless Steel Warm Edge/Guard Spacer to provide warm edeg o glass.
• Lowest Seal Failure Rate in Industry. (Beats closet competitor by 1600%.)

Conservision 800 is the most advanced dual pane glass technology available anywhere today. Conservision 800 combines the high efficiency heat saving and heat reflecting properties of the best triple silver low E glass with a second low E glass pane on the inside of thee home. The inside Low E aids in reflecting the heat from your home’s furnace back into the house. Because it is on a touchable surface, it is encased in a thin layer of low iron glass which actually makes it clearer than clear glass

Does Conservision 365 Smart Glass Really Matter?

Glass is glass, right? Well actually, not at all. Window glass is all about efficiency – keep the outside out and the inside in. The best way to achieve this is by combining multiple technologies. Glass coatings, a thin layer of UV reflective material, are the first defense. The second is the spacer which separates the layers of glass. 365 Smart Glass utilizes non-conductive, state-of-the-art spacer technology with the lowest failure rate in the industry, backed by our lifetime warranty. Multiple layers of glass are the third. But more layers have proven to be less efficient than just two with coatings on each side of each pane(2 is greater than 3). 365 Smart Glass Conservision choices have been specially formulated to reject the sun’s heat, letting in more light in and keeping more heat out in the summer, while retaining heat during winter. Your home stays cool and comfortable through every season. Condensation is virtually eliminated, providing a healthier atmosphere inside. What’s more, Conservision provides exceptional fading protection, blocking the sun’s damaging ultraviolet rays (a leading cause of fading), keeping your furniture, carpets, curtains and wall coverings beautiful for years to come.
