Vinyl Windows & Doors

When you start thinking about getting replacement doors and windows, you typically consider several things: what you like about your current doors and windows in terms of appearance, operation, and trim; any annoying problems the doors and windows have, such as condensation, cold drafts, poor operation, overheating, or water leaks; whether they let in adequate natural ventilation; whether you prefer operable windows over fixed ones; how energy efficient they are; and the things you would like to improve about your doors and windows, such as security and noise reduction.

One of the reasons why we chose vinyl is its exceptional molecular structure and quality. The nature of the material is such that it doesn’t let any external agents to stay on its surface. Take water, for instance. Since vinyl is one of the forms of plastic derived from polyvinyl chloride, it doesn’t entertain water and hence prevents corrosion and rust of the furniture. Next, vinyl is extremely affordable. Due to its easy manufacturing process and abundant demand, it is sold at a reasonable price. We are lucky to have some of the best suppliers of vinyl granules that help us maintain the same standards that we have maintained for nearly half a century.

We use Hydraglass 50 warm edge technology on a Super Spacer platform to custom manufacture your high performance vinyl windows. Our windows will last a lifetime with no maintenance, plus they are protected from fading courtesy of 100% pure virgin UPVC. Furthermore, we use Low-E glass for superior energy efficiency, and back up our professional installation with a lifetime warranty.
