Installing Nailup Glass Block Windows in lieu of conventional glass block windows can be a fast and easy alternative. The installation process is simplified to the extent that the average DIY homeowner can take on this simple weekend project without hesitation.
Nailup Glass Block Windows offer the same benefits as conventional Glass Block Windows. They are great for allowing natural light into a bathroom while at the same time maintaining your privacy. The durability of glass block windows makes them the perfect choice for basement windows that are vulnerable to damage from kids playing in the backyard.
Nailup Glass Block Windows Installation Steps
STEP 1 – Demolition: Remove the existing window sashes and hardware. Use a crowbar to pry away the old window frame.
STEP 2 – Set the Block Window in Place: Set the new glass block window in place and center it within the rough opening. The nailing fin should overlap the exterior wall sheathing. Apply a generous bead of caulking between the nailing fin and the sheathing to form a complete seal.
STEP 3 – Check for Level: Use small shims to level and plumb the window before screwing the fins in place. Secure the window to the 2×4 structure with 2” long #10 woodscrews and washers.
STEP 4 – Install Flashing: Place the foam flashing corner strips over the nailing fins. Install underlayment paper over top of the fins in a shingled pattern. This video illustrates how to properly flash a flanged window.
