The Impact Window Buying Guide

Begin with the opening schedule

List every opening by room or elevation, record the operation you want, and keep measurements, photos, and notes under the same unique label.

Match the documented assembly

Impact performance belongs to the complete assembly: frame, glass, mullion, hardware, anchoring, substrate, size, and pressure. A brand name alone is not a specification.

Separate product from project cost

A complete budget may include product, freight, liftgate or site handling, permit, removal, substrate repair, installation, waterproofing, interior and exterior finish work, and disposal.

Collect the paperwork

Before approving fabrication, retain the quote, configuration drawing, product approval references, glass specification, finish, handing, order acknowledgement, warranty, and receiving instructions.
