When insulating attics, we begin by sealing all gaps, openings, cracks, and holes between the attic and the heated area below. We ensure proper ventilation with vents and air chutes, and we finish by using high quality insulation to increase the effectiveness of your home or business’s heating systems, keeping you and your family more comfortable during the frigid winter months.
It’s important to ventilate your attic in order to prevent moisture issues, such as mold growth and ice dams. It also protects your roof shingles from overheating and premature aging. Learn more about our quality attic ventilation systems here.
Attic Insulation Requirements
Before 1979, there were no codes or standards for building insulation, including attics. Now, attic insulation R-values are R-50 or more in Minnesota, for both existing and new construction. This equals about 14″ of cellulose or 18″ of fiberglass.
At MGT Insulation, we offer free insulation evaluations and thermal imaging to determine what your attic needs. We specialize in attic insulation removal and replacement that will increase your energy efficiency, comfort, and indoor air quality. Contact us today to learn more!
Attic Insulation Installation
Our comprehensive attic insulation process ensures that your attic will function efficiently to keep your home or business comfortable, safe, and cost-effective. The steps differ depending on the structure of your home or business, and we address all structures with the same level of care and craftsmanship.
Here’s how we approach the attic insulation process:
Step 1: Diagnostic Testing
Our highly trained technicians use state-of-the-art equipment to identify areas of energy savings for you. An infrared camera, especially done in conjunction with a blower door test, can identify uninsulated and poorly insulated attic areas. Our diagnostic testing also quickly pinpoints unsealed attic bypasses.
Note: We also recommend the investment in an independent energy audit from your utility company. The cost is fairly low and heavily subsidized — meaning that its actual cost would be much higher without the contribution by the utility.
Step 2: Prep Exterior Work Area
We carefully protect your home, business, and belongings with thorough worksite preparation, including clean drop cloths, plastic, window jamb protectors, corner guards, and our state-of-the-art Air Scrubber filtration system.
Step 3: Seal Attic Penetrations
Bypasses and air leaks, including those left from construction or by plumbers, electricians, carpenters and heating contractors are sealed to keep your indoor air “in.”
Step 4: Vent Attic Mechanicals
Exhaust fans are properly vented to the outside.
Step 5: Build Storage Area
If desired, a storage area is designated and protected from insulation.
Step 6: Kneewall Wall Treatment
Interior walls are insulated to create a continues thermal envelope. (Applies to structures with additional half-stories, such as 1 ½ or 2 ½ story homes.)
Step 7: Insulate Slant Walls
Insulation is added to fill voids in your slant walls (Applies structures with additional half-stories, such as 1 ½ or 2 ½ story homes.)
Step 8: Seal Kneewall Bypasses
THERMAX™ brand foam board or dense-packed insulation is installed at the kneewall bypass area to create huge energy savings and aid in ice dam prevention (Applies to structures with additional half-stories, such as 1 ½ or 2 ½ story homes.)
Step 9: Install Chutes
If necessary, chutes are installed for attic ventilation.
Step 10: Build Attic Dam
A sturdy, wooden dam is installed to keep insulation in place and to protect attic access.
Step 11: Place Markers & Certifications
Markers identifying the number of inches of insulation and certificates indicating the type of insulation and number of bags installed per UBC are placed for visual confirmation.
Step 12: Open Blow and/or Peak Insulation
Your attic and/or peak is insulated to a predetermined R-value using one of our high-quality insulation products.
Step 13: Hatch/Access Door Treatment
Your hatch or access doors receive THERMAX™ brand foam board or fiberglass insulation, weather-stripping, and possibly house wrap, door sweeps, and barrel bolts as needed to continue your thermal envelope.
Step 14: Install Roof Vents
Roof vents may be added for ventilation or crew access as needed. They are available in black, brown, or grey.
Step 15: Post Blower Door Test
We perform another blower door test to determine your home or business’s increase in comfort due to air and bypass sealing.
Step 16: Health and Safety Check
Our crews perform a “Worst Case Scenario” test to ensure that your structure is safe from carbon monoxide and your family, pets, employees, or customers are protected.
Step 17: Clean Work Area
Our crews now how to broom clean and vacuum!
Step 18: Post Inspection
To ensure that our job is complete, we walk with you through your home or business to inspect the work. During this time, we’ll answer any questions, get your stamp of approval, and have you complete our job satisfaction survey.
