Navigating Continuous External Insulation Code Requirements: Architect Edition

Written by Thermal Building Supply | Aug 10, 2023 12:52:30 PM

As the demand for energy-efficient and sustainable buildings continues to rise, architects are taking the lead in integrating innovative solutions into their designs. One such solution gaining prominence is continuous external insulation. However, meeting code requirements while incorporating this insulation strategy can be a complex task. In this guide, we explore how architects can design buildings with continuous external insulation while adhering to relevant code regulations.

  1. Understand Local Building Codes:
     a. Insulation Requirements: Determine the prescribed R-value or U-value for the insulation system in your area. These values dictate the thermal performance of the insulation material. Some insulation products like polyiso have r-values that degrade over time- ThermalTight products retain their r-value over the life of the building.

     b. Fire Safety: Check for fire resistance standards that the chosen insulation materials and cladding systems must meet. Some insulation materials may require additional fire-retardant treatments.

     c. Thermal Bridging: Many codes now address thermal bridging to ensure the continuity of insulation layers. Familiarize yourself with these provisions and design to minimize heat transfer through connections and junctions.

  1. Incorporate Proper Installation Techniques:
     a. Attachment Methods: Choose attachment methods that align with code requirements. Whether it's mechanical fixings, adhesives, or a combination, ensure they adhere to load-bearing and fire safety standards. This is also especially important in regards to window detail, and the ThermalBuck solution can help mitigate issues in this area.

     b. Air and Moisture Barriers: Integrate air and moisture barriers as necessary to prevent infiltration and manage condensation. These barriers are critical for maintaining the long-term performance of the insulation system. ThermalTight products incorporate a water resistant barrier that allows the building to breathe while also keeping moisture out- feel free to reach out to us about this.

Incorporating continuous external insulation into architectural designs while meeting code requirements demands a thorough understanding of local regulations, collaboration with experts, and meticulous documentation. By embracing these principles, architects can create buildings that not only reflect innovative design but also contribute to a sustainable and energy-efficient built environment.
