Warmup Insulated Underlayment for Foil Radiant Floor Heating System 110 Sq Ft

Warmup Insulated Underlayment for Foil Radiant Floor Heating System 110 Sq Ft

The Warmup Insulated Underlayment 110 Sq Ft is specifically designed for use beneath the Warmup Foil Radiant Floor Heating System to improve heating efficiency, reduce heat loss, and provide excellent acoustic performance. Installed between the subfloor and the foil heating mat, this lightweight insulated underlayment helps direct more heat upward into the finished floor, allowing your electric radiant floor heating system to perform more efficiently.

Manufactured from grooved polystyrene with an integrated foil moisture barrier, this insulated underlayment provides thermal insulation while helping reduce contact noise between floors. It is an ideal solution for laminate flooring, engineered wood flooring, floating luxury vinyl tile (LVT), and carpet installations used with the Warmup Foil Heating System.

Designed specifically for floating floor installations, the Warmup Underlayment is quick to install and adds only a minimal amount of floor height while helping maximize the performance of your electric underfloor heating system.

How It Improves Heating Performance

Without insulation, a portion of the heat produced by an electric floor heating system can be lost into the subfloor. Warmup Insulated Underlayment creates a thermal barrier that reflects more heat upward toward the finished flooring, allowing rooms to warm more efficiently while helping the heating system reach operating temperature faster.

The integrated foil backing should always be installed facing downward toward the subfloor, where it also functions as a moisture barrier to help protect the flooring assembly.

Why Use Warmup Underlayment?
