Cool Guyz measures and CNC-machines every acrylic insert for the actual window opening and portable AC hose adapter. The result is a stable, clean-looking panel that seals far better than cardboard, fabric, plywood, or a generic plastic kit. We fabricate solutions for sliding, casement, and awning windows, patio doors, dual-hose systems, and difficult openings, with installation across Metro Vancouver, the Lower Mainland, and Fraser Valley.
