Ellison Window Costs
The Atrum 8700 series is the same window as the Reliabilt 3500 window and is also sold by Ellison. It is a decent vinyl window that will offer okay numbers and results. The 8700 includes all of the upgrades of the 8500, along with a better warranty, aluminum sash reinforcement and one extra color option in bronze. The reinforced sash should improve the performance of the window - the 3500 has a DP35 rating. Definitely one of the those windows that is probably just fine if you get the right price point and find a good installer who knows what he's doing and doesn't take shortcuts. Comparable to the Alside Mezzo.
