Sustainability StudiesSustainability Studies

This one hour presentation provides for an understanding of sustainable wall construction using basic panelized wall units vs. other modular products. The featured sustainable wall units presented will be Koreteck solid core insulated panels.

Specifically we will give a brief description of Koreteck solid core insulated wall panel systems and then discuss comparative data for Koreteck vs. cmu, insulated concrete forms, insulated tilt up wall construction, and autoclaved aerated concrete panels. This data will compare each different wall system as they pertain to wall costs per square foot, steady state R-values, installation rates, and cooling and heating loads.

Sustainable interior finish systems for the Koreteck panels will also be presented by Gigacrete natural mineral cement-based interior wall coatings.

Following lunch we will walk outside and inspect a Koreteck wall mock-up with a brick veneer exterior and a Gigacrete interior finish system.
