This design fundamental is never more true than in the demanding world of windows and doors. At Loewen Windows and Doors of Cape Cod, we strive to not only provide our customers with the world’s most inspiring windows and doors, but also the most reliable. As with all good design, form follows function. That’s why we focus our attention and craftsmanship not only on aesthetics, but on performance. Thermal performance, strength and stubborn resistance to air and water infiltration are at the core of all Loewen windows and doors, and it’s what makes them the perfect match for the harsh climate of Southeastern Massachusetts, Cape Cod, Nantucket and Martha’s Vineyard.
