Vinyl Features

Vinyl is a very affordable and durable product used in many replacement windows and new construction windows. But unknown to most people outside the window industry “not all vinyl or vinyl extrusions are created equal”.

Just like most things in life vinyl extrusions can be purchased in variety of thicknesses with a variety of internal chambers. Though not visible once a vinyl window or door is assembled, the thickness of the vinyl and the amount of internal chambers has a direct correlation on the energy efficiency and strength of the window or door. The thinner the vinyl and the less chambers, the less expensive the vinyl extrusion but unfortunately this cost is never past to the consumer by manufacturers using these sub-standard systems. At Thermo-Twin we use only the best extrusions produced by Chelsea Building Products located a mile from our plant in Oakmont, Pennsylvania. Chelsea’s thickness of material and multi-chamber design along with the craftsmanship of Thermo-Twin’s manufacturing process guarantees you an exceptional, quality-built product that perform and look beautiful from day one and many years after that.

Another large factor in vinyl is the purity. The purer the vinyl, the better the finished product and the longer the life expectancy. At Thermo-Twin we only manufacture with vinyl extrusions which were created from 100% virgin vinyl.  In doing this, we at employee owned Thermo-Twin guarantee from day one your windows or doors, whether bright white or one of our many colors, will be a beautiful addition to your home.
