Okna vs. Alside
I have had two contracting companies provide me with quotes for replacement vinyl windows - about 18 needed in total with most being DH windows, 3 sets of sliders and two 3-lite casements. One contractor uses the Okna Insul-Tech series windows. I think its the Okna 500 series but am not quite sure and will have to clarify with the contractor. The other contractor uses the Alside 8000 series windows which they say are specifically made for them. From what I have read, the 8000 series is only made for certain Alside dealers and is maybe one step above the Alside Sheffield line and one step below the Alside Preservation series. According to each contractor, both would qualify for the tax credit under the stimulus plan. Is the Okna Insul-Tec or Alside 8000 series window better?
