Certainteed-by Insulate Slimline Series 400 Windows

#1 Post by Mariners » Fri May 06, 2005 10:46 am

I'm looking to replace 9 windows and 1 slider. I have 40 + year old aluminum windows. I was told that the Slimline Series #400 from Certainteed would work best for my house.
Can any one give me suggestions if this window is as good as there regular Certainteed Series #200.
The lowest bid is $6,600.00 for the slimline windows.

And $5,800.00 for the Certainteed full series #200.
Any help would be great.
Thanks
