Twinsulator Aluminum Windows in Plano
Custom Windows for Your Richardson Home
Aluminum window replacement involves more than choosing a frame color. Aluminum conducts heat readily, so the frame design, insulated glass unit, spacer, weather sealing, and installation all matter. The NT Window Twinsulator combines narrow, durable aluminum construction with thermally improved components for projects where strength, glass area, and clean sightlines are priorities.
At Southern Windows & Doors, we provide custom-built windows for homes, apartment complexes, and businesses operating from residential-style properties. We use locally made NT Window products, and guide each project from measurements and product selection through installation.
Twinsulator Aluminum Window Construction
Twinsulator uses powder-coated aluminum extrusions with a thermally improved aluminum frame and sash. Its listed glass package is 3/4″ dual-glaze Cardinal Low-E 366 double-strength glass with a Warm Edge XL Edge Spacer.
XL Edge Spacer & ThermaProtect
The XL Edge Spacer and ThermaProtect™ address different parts of the window. The spacer sits at the edge of the insulated glass unit, while the thermal barrier addresses heat transfer through the aluminum frame and sash.
Warm Edge XL Edge Spacer
The XL Edge Spacer System combines stainless-steel spacers with a dual-seal silicone system at the edge of the insulated glass unit. Stainless steel is used in place of the aluminum spacers found in some insulated glass designs.
ThermaProtect Insulation Barrier
ThermaProtect is an insulation barrier integrated into the thermally improved aluminum frame and sash. It addresses aluminum’s natural conductivity while retaining the material’s structural qualities.
Neither component should be evaluated alone. The appropriate configuration depends on the complete frame, glass, spacer, thermal barrier, weather seals, opening conditions, and installation plan.
Our Plano Aluminum Window Installation Process
We begin with a free in-home consultation and estimate. Professional measurements help us assess opening dimensions, frame conditions, operation, appearance requirements, and access before custom-built windows are ordered.
Apartment complexes and occupied commercial-residential properties may also require sequencing around residents, business activity, and building access. We keep the sales process straightforward and don’t use high-pressure tactics. Our focus on professional installation is supported by strong customer ratings and a national award for installation excellence.

Take a Break From Mother Nature’s Extremes with ThermaProtect™
For maximum insulation, our exclusive ThermaProtect™ insulation barrier offers the very best in thermal protection from the elements. On its own, aluminum is known as a highly conductive material allowing energy to flow freely through the metal.
Take that inherent strength and combine it with a technologically advanced application of a unique thermal barrier and you have the perfect design for window construction.
