Interested in learning how to install batt insulation? This video shows how to properly install bad insulation to resonate grade 1 installation requirements.
When beginning any insulation installment project, your goal is to ensure the building is healthy, safe, comfortable, durable, energy efficient and that insulation is added in an environmentally responsible way. First walk through the home and take note of all the areas that need to be insulated and what needs to be done in advance of the insulation going in. There are many places in a home that require insulation to meet specific energy efficiency criteria and many of these can be missed if they’re not noted beforehand.
Look at the framing to ensure it’s in place and ready for installation. It’s important to pay attention to the small spaces and insulate them before drywall is installed. Check any band systems, which are part of the floor system that separates the first floor from the second floor. Make sure there are no penetrations moving through the band. If you find a crack you’ll want to ensure its air sealed before insulation is placed.
Also be sure to inspect your windows. If you find a crack between the window and the rough framing it can be filled with multiple appropriate products. For small cracks you may want to use caulk. For larger cracks, expanding foam works really well. If it’s a really large crack you may want to back fill it with insulation and then seal over the top with an air barrier. The important thing is ensuring you have an air barrier in place the stop airflow around the window.
One of the things you want to avoid when installing insulation is wind intrusion. Wind or air that moves through the insulation reduces the R-value of insulation. Use a vented soffit on the outside to protect the insulation from the air that’s coming in through the soffit.
For attics you may want to use an ICAT, or insulation contact airtight recessed scan. This fixture allows you to insulate over the recess scan instead of boxing around it and leaving a void in our attic insulation. It also ensures the connection is airtight so you don’t lose home heat to the attic or bring attic air into the home.
Ensure insulation is installed properly in small and irregular cavities, baffling is in place at the vented soffits, cantilevers and similar framing are insulated and capped, and that ICATS and can lights are completely insulated top and sides.
When insulating a home to be Energy Star certified, you want to ensure you’re following the latest energy code standards. That means care and attention should be paid to those things that increase the energy efficiency of the home. An insulation contractor plays an important role in meeting the energy code requirements needed to make sure that the exterior sheathing of the air barrier extends from the first floor to the second floor.
