Commercial Windows, Doors, & Insulation Technologies

At INTEC we know that contractors want to have confidence that the windows and doors on their building are the right ones, and that they were installed well.

The problem is they don’t have the in-house expertise to do it themselves. That leaves you worried about the end result of your project. We believe contractors deserve a windows and doors expert with the knowledge and experience to get the job done right the first time.

We understand how worrisome and stressful these problems are. That’s why we’ve been serving contractors for over 35 years and have complete over x# of project (or installed x# of windows).

When we receive requests for commercial windows, Intec knows the importance of making sure the project is done properly, Starting with having our technicians accurately record the measurements while also paying close attention to the physical condition of the property. Our team of experts excel at unique specifications and are highly skilled when it comes to historic windows as well. Intec’s primary supplier is Quaker Windows. The quality of windows offered as well as the warranty that comes standard, puts them above the rest. Between our skilled team of technicians and our stellar choice of a window supplier, we’re able to exceed any window expectations put before us.

Insulation is also key to providing a more energy efficient, comfortable, and healthy building in which to work or live. Although there are many various types of insulations, it’s imperative to have something that wards off moisture and air infiltrations, which can increase energy bills 10%-40% if not taken into consideration. Spray Foam insulation is by far the best method and will protect the building against air infiltration. Our skilled technicians have been trained in knowing the most effective way to save on energy costs. When you’re in need of spray foam insulation, Intec will be ready to service you.
