Overview of Milwaukee’s Climate Impact on Insulation Needs

Milwaukee experiences a humid continental climate characterized by cold winters and warm summers.

This diverse weather pattern underscores the importance of selecting insulation materials that can withstand temperature fluctuations and moisture.

Proper insulation not only enhances energy efficiency but also prevents issues like condensation and mold growth.

Comparison of Common Continuous Insulation Materials

Foam Board Insulation:

  • Rigid panels with high R-values per inch thickness
  • Moisture-resistant and easy to install
  • Ideal for exterior wall sheathing

Spray Foam Insulation:

  1. Expands to fill gaps and crevices
  2. Provides air sealing and insulation in one application
  3. Suitable for irregular surfaces and hard-to-reach areas

Mineral Wool Insulation:

  • Fire-resistant and sound-absorbing properties
  • Excellent thermal performance
  • Ideal for cavity walls and rainscreen applications
Continuous Insulation Material R-Value per Inch Moisture Resistance Fire Resistance
Foam Board 4.0 – 6.5 High Moderate
Spray Foam 3.5 – 6.5 High Moderate
Mineral Wool 4.0 – 4.3 High High

How to Ensure Proper Installation of Continuous Insulation

  1. Prepare the substrate by cleaning and repairing any damage.
  2. Install insulation boards tightly together with staggered joints.
  3. Use appropriate fasteners and adhesives per manufacturer guidelines.
  4. Seal all gaps and penetrations with expanding foam or tape.
  5. Install a weather-resistant barrier over the insulation layer.
  6. Regularly inspect the installation for any signs of damage or gaps.

Common Installation Pitfalls to Avoid

  • Improper sizing and spacing of insulation boards
  • Inadequate sealing around windows, doors, and penetrations
  • Failure to account for thermal bridging
  • Skipping the weather-resistant barrier installation
  • Improper storage and handling of insulation materials
Installation Step Tools Required Common Mistakes
Substrate Preparation Scraper, Patching Compound Failing to repair damage and clean surface
Board Installation Fasteners, Adhesive Improper board sizing and spacing
Gap Sealing Expanding Foam, Tape Inadequate sealing around penetrations

Navigating Milwaukee’s Building Code for Continuous Insulation
