Winter’s here, and a properly insulated attic can make all the difference. If you can’t schedule professional insulation installation, there are DIY solutions to help keep your home warm. Here are some practical tips to keep the cold out and the warmth in this season.
DIY Attic Insulation to Improve Efficiency
Seal Cracks and Gaps
Use caulk or spray foam to seal any noticeable cracks and gaps in your attic, especially around lights, electrical boxes, fan exhausts, or any other gaps you might see to keep drafts out.
Add Extra Insulation to Under Insulated Areas
If you have spare fiberglass batt insulation, place it in under-insulated areas to boost insulation, paying special attention to corners and hard-to-reach spots. A better solution is to rent an insulation blower and add blown-in insulation on top of existing insulation material.
Use Draft Stoppers
Install weatherstripping around interior attic hatch doors to prevent warm air from escaping through the cracks and/or cold air entering.
Ensure Proper Ventilation
Make sure any ventilation or exhaust chutes in the attic are properly installed and adequate insulation is provided all the way out to the eaves. Unless your attic is properly sealed with no air leaks and has a high level of insulation to prevent moisture buildup, ventilation is important to allow trapped moisture laden air to escape. That moisture, if allowed to remain will cause mold and mildew, and lots of damage.
While these DIY attic insulation tips can help reduce drafts and conserve warmth, professional insulation is still the most effective solution. If you’re ready to make a lasting investment in your home’s comfort, we’re here to help.
