Easy Process Of Installing Foam Board Insulation To A Ceiling
Rigid foam insulation is considered one of the best options when it comes to insulating your home. It is comparatively inexpensive when you compare it with other types and is extremely easy to install. Take into consideration the usage of insulation in the basement, betwixt floors, ceilings or even in the walls. You normally glue and nail it when you apply it to ceilings and other locations, in order to make sure that it doesn't come loose later on. If you are looking to install foam board insulation to a ceiling, then go through the below-mentioned steps carefully & achieve the desired result of your work:
- Measurement: First of all, take the measurement of the space betwixt the ceiling joists before you move the taken measurements to the rigid foam insulation. Mark the measurements & then with the help of a utility knife, cut the insulation through the marked lines in order to make sure that it fits the space between the joists.
- Squirt Construction Adhesive: Now, spray construction adhesive in a zigzag line in betwixt the joists and allow it to sit for a few minutes in order to get it tacky.
- Place The Insulation Between The Joists: Next, lay down the insulation betwixt the joists and take hold of it there for a second or two as long as it adheres. Repeat the same process betwixt each joist. If there are obstructions, for instance, light fixtures, take the measurement of the opening and cut it out with the help of a utility knife. Make the opening at least 3 inches wider on all sizes than electrical items, such as light fixtures, which in turn will protect you against fires.
- Slip Washers Onto Nails: After that, slip washers onto nails before hammering the nails into the rigid foam insulation. The nails will add a bit of strength & security to the insulation if the glue doesn't hold. The washers will help prevent the nails from tearing through the insulation.
- Squeeze A Bead Of Caulk Along The Seams: Finally, squeeze a tube of caulk through the seams betwixt the boards and the joists in order to seal them tight. Press as well as move your finger smoothly along the bead of caulk in order to flatten it out and seal it to the joist and insulation.
Additional Information
The only time that you, in all likelihood, need to add rigid insulation to a ceiling is in a retrofit of a cathedral ceiling. Regular ceilings probably are underneath attics with either batt insulation betwixt the joist bays or, in some cases, rigid insulation betwixt the rafters. Rigid boards are created from either polyisocyanurate foam, producing what tradesmen call ISO or blue board, or extruded polystyrene, or XPS, which is exceptional for moist conditions. Rigid insulation provides a practical, inexpensive substitute to spray foam, as it offers a strong air seal. Contrary to exterior applications, in which you secure rigid boards with screws positioned along 2-inch plastic washers, the comfortable sides of the board itself secure it to ceiling framing as long as drywall is installed over it.
