Gentleman,

After the installation of your Series 5400 window on 2/4/08 I had to wait until cold blistery penetrating rains and below freezing conditions but the window to test before I could honestly evaluate it. It SUPERBLY Passed.

We no longer experience cold drafts or condensation on the panes of glass. It is a pleasure to stand by it and not feel chilled or see leakage.

A team of skilled men expertly installed it. Within three hours or so they left with the job well done.

We sincerely recommend your company.

Yours truly,

Bob P.
