The windows were shipped with no protection.
All sashes were already installed, unlike the sample order. This made offloading of triple glazed windows a nightmare since the placement of windows in the container did not allow for use of forklift.
Once some of them were moved for forklift to be used, they dangerously bent under their own weight.
Since sashes are already installed, it is a logistical nightmare to install these windows due to how heavy they are. All local installer refuse to touch them. The fact that they use old technology to silicone the glass made it extremely difficult and expensive to remove the glass prior to installation to make it manageable.
Once the order was placed, the communication effectively ceased and the seller ignored my questions and issues.
