Under Concrete Prodex Total 5M – Comprehensive Product Details
Engineered for Under Slab Applications
Under Concrete Prodex Total 5M is a high-performance reflective insulation specifically designed for installation beneath concrete slabs. With a durable multilayer structure, it provides a powerful thermal barrier and moisture control solution, making it ideal for applications requiring long-lasting performance beneath flooring systems.
Optimized for Radiant Floor Heating Systems
This product excels in radiant floor applications, enhancing system efficiency by significantly reducing heat loss through the slab. Its reflective surfaces and inner core deliver a strong thermal break that improves heat retention within living spaces.
Key Performance Metrics
Compression Resistance: Maintains less than 9% compression under concrete pressure, preserving insulation performance and structural integrity.
Heat Loss Reduction: Proven to reduce heat loss by up to 56%, enhancing overall energy efficiency.
Thermal Break: Minimizes conductive heat transfer, maintaining consistent floor temperatures.
Built-In Moisture and Radon Control
Prodex Total 5M acts as a formidable barrier against moisture and harmful gases. Its vapor barrier rating (per rating less than 0.1) effectively blocks ground moisture, preventing condensation and contributing to a drier and healthier indoor environment. Additionally, it serves as a radon barrier, reducing the risk of gas infiltration from the soil.
Moisture & Gas Protection Features
Vapor Barrier: Stops moisture migration, eliminating slab dampness and condensation.
Radon Barrier: Provides an additional line of defense against radon gas intrusion from the ground.
Seals Around Nails: Ensures a continuous barrier even when fasteners are used, preserving insulation and moisture protection properties.
Durability and Construction Efficiency
This insulation roll is engineered for quick and straightforward installation. At 4 ft x 175 ft (700 sq ft), it offers ample coverage while being easy to cut and position. Its rugged build resists wear during construction and installation, contributing to long-term reliability under the slab.
