As both the manufacturer and installer, there's almost no limit to what we can produce. Almost any shape is possible, and we will custom make all of our high performance windows based on your designs. In an industry that's brought up middle men installers who are overly attached to "standard sizes" and obscene costs for special orders, buyers have to beware which pieces of advice are "best for the customer, " and which are "best for the seller." Of course, this also applies to traditional shapes at larger than common sizes.

These beautiful windows are made from heavy walled vinyl extrusions. They are structurally designed with multiple irregular chambers to be strong, energy efficient and maintenance free. Our vinyl is formulated to withstand sun exposure and we warranty it against blistering, chipping, flaking, rust, rot and peeling (see our limited life-time warranty for details). The Energy Guard Fixed system incorporates a beautifully beveled exterior glazing leg to simulate a historic putty glazed appearance. Solid vinyl (PVC) is an excellent insulator and dramatically reduces the transfer of heat and cold.
