Step 4 insulate the gap between the window frame and the rough opening by filling it with expanding spray foam insulation.
Putting a window in concrete wall.
The window opening should be a minimum width of 20 inches and at least 24 inches in height.
Anchor this 2x4 to the concrete with screws or anchors.
In a concrete wall without wood framing install the window framework by fastening it into the concrete wall with self tapping concrete screws.
In total the window should offer 5 7 square feet of escape space and the bottom of the window must be.
Measure the concrete opening and cut a 2x4 to fit across the lower sill.
If you need to install a new window in a concrete wall cut a hole that s large enough to hold your new window.
Back from the concrete wall.
The opening should be two inches wider than the door frame and about an inch taller in height.
By and large the process of installing window in concrete wall involves specifying boundary of the window on the wall placing l shape steel or constructing reinforced concrete beam as a lintel making an opening inside specified boundary smooth edge of the opening placement of windows and finally placement of water proving agent around the frame of the window.
Use concrete screws to anchor the sides of the frame to the concrete walls.
Allow the lintel to go off before fitting the window.
Screw the top of the frame into the ceiling plate or joists.
Screw the top plate to the joists and align the studs directly under the floor joists.
Drive concrete screws through the frame and into the cinder blocks to secure the window in place.
Place it 3 ft.
Remove the glass from the window and lift the frame into the window.
Use wood shims and a level to make sure this piece is level.
Install a new window that fits the space and caulk around the frame to waterproof it.
Put the window frame into place and secure it with nails or screws.
Follow the same steps for the other 3 sides of the concrete opening.
Fix the lintel into the wall using cement making sure that it spans the whole opening and is securely fitted.
Partially drive 3 in 7 6 cm deck screws into the bottom of the frame and push them into the wet concrete below.
Measure and cut each stud for a tight fit.
For a block wall installation fasten with rust resistant screws using a toe nail method through the jambs into the head and sill boards at each corner.
Add another set of marks across the top of the frame to represent a steel lintel that will support the load above the door.
Drill holes through the side of the window frame and into the cinder blocks with a hammer drill.
Then make a custom frame and push the window in place.
Erect a temporary 2x4 support wall if the joists are perpendicular to the wall you ll be cutting.
