Managing water vapor inside wall assemblies directly affects the long-term performance of a building. Construction professionals rely on laboratory methods to determine how well insulation and sheathing resist vapor intrusion. One such method, ASTM E96, measures water vapor transmission under controlled conditions.
What Is the Best Insulation for Basement Walls?
Basement walls are subject to continuous thermal and moisture pressures from surrounding soil. Concrete alone cannot regulate indoor temperature or prevent vapor intrusion under these conditions. The best insulation for basement walls combines high R-values with durable facers to withstand long-term below-grade stress.

What ASTM C665 Means for Modern Insulation Strategies
Building insulation plays a central role in managing energy, moisture, and indoor safety across residential and light commercial construction. Industry standards like ASTM classifications help clarify what’s expected from materials that fill wall cavities and work alongside vapor barriers or continuous insulation.
How ASTM D1621 Defines Compressive Strength for Rigid Insulation
Thermal performance is only part of what defines high-quality rigid insulation. When exposed to pressure from fasteners, cladding, or heavy loads, materials must also resist deformation. That’s why the industry uses ASTM D1621 to quantify how well rigid insulation materials perform under compressive force.

Passive House Thermal Insulation
Achieving energy efficiency is a top priority in today’s construction industry. With more builders seeking ways to reduce energy costs and improve environmental sustainability, standards have evolved. Passive House construction has emerged as a leading benchmark for high-efficiency buildings, where thermal barriers serve a significant function.
