SUMCO measures, specifies, coordinates and installs replacement and new-construction windows. Our current featured NT Window products are the Executive 700 Series and Presidential 900 Series.
Two NT Window vinyl platforms with multiple glass, color, grid and performance configurations.
Final window selection depends on the opening, application, size, glass package, installation method and project requirements. SUMCO will quote the exact configuration.
High-performance core offering
A 3-1/4-inch multi-chamber frame with heavy-wall construction, fusion-welded frame and sash, metal-reinforced meeting rail, dual FinSil weatherstripping and insulated glass options.
Premium performance / configuration offering
A 3-1/4-inch chambered frame with full aluminum-reinforced meeting rails, dual FinSil weatherstripping, insulated glass and additional premium glass and thermal options.
Window performance is more than the name on the frame. SUMCO looks at the actual glass package, U-factor, SHGC, structural requirements, installation method and opening condition.
Measures heat transfer through the window assembly. Lower values generally mean better insulating performance.
Measures solar heat gain through the glazing—especially important for Central Texas sun exposure.
Structural ratings help match the window to the project's size, exposure and installation requirements.
Proper measurement, flashing, fastening, sealing and finish work are part of the window system.
Use NT Window's current manufacturer pages and literature for detailed product specifications, shop drawings, performance information, glass options and warranty information. Product specifications can change, so the manufacturer source should control the final quote.
