The Problems with Foam Board Insulation & Why Prodex Total Is Better
Why Rigid Insulation Boards May Not Be the Best Choice
Many homeowners and builders rely on foam board insulation (also called rigid insulation, rigid board insulation, or rigid building insulation) to improve energy
efficiency. However, these panels come with significant drawbacks that impact thermal performance and moisture control.
Below, we discuss the two biggest problems with foam board insulation and why Prodex Total Insulation is a better solution.

1. Foam Board Insulation is Too Rigid to Seal Gaps
Why Rigidity is a Problem
Rigid insulation boards lack flexibility, making them difficult to install on surfaces that aren’t perfectly flat.
Problems Caused by Poor Sealing
- Air Leakage – Gaps between insulation boards allow air to escape, reducing energy efficiency.
- Moisture Infiltration – Unsealed gaps lead to mold, mildew, and wood rot.
- Reduced R-Value – Over time, foam board insulation becomes less effective in maintaining indoor temperatures.
How Prodex Total Insulation Solves This Issue
Flexible & Adjustable: Unlike rigid insulation, Prodex Total is a roll insulation that conforms to any surface, sealing cracks and gaps.
True Vapor Barrier: Prevents moisture buildup and eliminates condensation risks.
Consistent R-Value: Maintains performance regardless of humidity levels.
2. Rigid Insulation Does Not Block Radiant Heat Transfer
Why Radiant Heat is the Main Cause of Energy Loss
Most insulation solutions focus on conduction and convection heat transfer, but radiant heat accounts for up to 75% of heat loss.
- In Summer: The sun’s radiant heat penetrates walls, making air conditioners work harder.
- In Winter: Heat escapes through walls, increasing heating costs.
Why Foam Board Insulation Fails Against Radiant Heat
❌ Rigid insulation does not reflect heat – It only slows down conductive heat.
❌ Higher energy bills – More strain on HVAC systems due to lack of radiant heat protection.
How Prodex Total Insulation Outperforms Rigid Insulation Boards
Reflects 97% of Radiant Heat: Keeps buildings cooler in summer and warmer in winter.
Increases HVAC Efficiency: Reduces heating and cooling cycles, prolonging HVAC lifespan.
Prevents Heat Loss: Improves indoor comfort, minimizing hot and cold spots.
Foam Board Insulation Fails on Uneven Walls
Why Rigid Insulation Doesn’t Work Well in Basements
Many basements and crawlspaces have uneven surfaces where foam board insulation struggles to create a tight seal.
Common Problems with Rigid Board Insulation in Basements
❌ Gaps & Air Pockets – Prevents proper insulation coverage.
❌ Moisture Penetration – Can lead to mold, mildew, and decay.
❌ Condensation Issues – Moisture can wick up from the foundation, causing damage over time.
Why Prodex Total is the Best Choice for Basements & Crawlspaces
Flexible and Adapts to Contours: Unlike rigid insulation boards, Prodex conforms to the shape of your walls, preventing air and moisture infiltration.
Superior Vapor Barrier: Blocks moisture from entering your home, reducing mold and mildew risks.
Prevents Foundation Rot: Keeps walls dry and protects against long-term structural damage.
