FAQ Section

Why Aluminum?

If you start with premium quality, solid aluminum frames and a high quality finish you will be eliminating years of cost and time consuming maintenance.

Do you cut down trees?

Remember, we don't cut down trees or use petroleum products to manufacture the best possible choice for your window & door needs.

Why we paint wood windows and doors

Wood windows and doors need to be painted and/or sealed to protect them from the environment. That adds to their total lifecycle cost and even with all of the maintenance effort, they can still swell, warp and crack with age.

How many styles for window screens?

We manufacture window bug screens in two styles, flat and long leg using roll formed aluminum framing and 16 X 18 charcoal fiber mesh held in place with a vinyl spline. Screens are held in place using traditional screen clips.
