Reflective Bubble White Poly - A Single Bubble Insulation


Product Overview

Single Bubble Reflective White Poly Insulation is specifically engineered for under-concrete and slab-on-grade installations. It features a durable layer of white poly on one side and a reflective foil surface on the other, with a single layer of air-bubble core that helps reduce heat loss through the ground and prevents upward moisture migration. This insulation creates a dependable thermal break beneath concrete, enhancing energy efficiency and comfort in slab-based construction.


Key Features

Purpose-Built for Concrete Installations


Under-Slab Thermal Barrier

Designed to be installed directly beneath poured concrete slabs, this insulation helps reduce heat transfer to the ground, which minimizes energy loss and improves thermal efficiency in conditioned slab spaces.


Moisture Resistance

Acts as an effective vapor barrier by blocking ground moisture and preventing it from entering the slab or interior space. This is especially important for preventing mold growth and maintaining indoor air quality.


Durable Construction

  • High-compression resistance suitable for use under concrete

Reflective Performance

  • Improves overall insulation value in multi-layer flooring systems

  • Reduces ground chill from affecting interior comfort levels

Applications

Residential

  • Basements with radiant or hydronic floor heating

  • Slab-on-grade living spaces

  • Heated garages and workshops

Commercial and Industrial

  • Warehouses and distribution centers with radiant floors

  • Commercial slab flooring in offices or retail spaces

  • Cold storage or walk-in freezers requiring thermal isolation

Agricultural and Utility Structures

  • Pole barns and sheds with poured flooring

  • Animal enclosures or kennels with floor-based heating

  • Greenhouses with slab or hydroponic systems

Key Benefits

  • Improved Energy Efficiency: Reduces heat loss into the ground, especially beneficial for radiant heated floors

  • Moisture Protection: Helps prevent vapor infiltration and related structural issues

  • Comfort Enhancement: Warmer slab temperatures lead to more comfortable interiors

  • Installation-Ready: Lays flat and cuts easily; install before rebar or wire mesh placement

Installation Tips

  • Lay insulation white side up.

  • Overlap seams by at least 2 inches and seal with vapor barrier tape

  • Ensure insulation lies flat beneath reinforcement mesh

  • Pour concrete directly over the insulation without adhesives

Benefits of Single Bubble Reflective White Poly Insulation for Under-Concrete Applications


Superior Thermal Performance

Reduces Heat Loss to the Ground

When used under concrete slabs, this insulation acts as a thermal break, helping to prevent the loss of valuable interior heat through the foundation. It’s especially effective in cold climates or radiant-heated slab systems.


Enhances Radiant Floor Efficiency

By reflecting radiant energy upward, it ensures more of the heat generated from in-slab hydronic or electric heating systems is directed into the occupied space rather than being lost into the subgrade.


Effective Moisture Barrier

Blocks Ground Vapor

The white poly outer layer functions as a strong vapor barrier, reducing the risk of moisture infiltration from below the slab. This helps prevent mold, mildew, and damage to flooring materials.


Minimizes Slab Condensation

Helps prevent cold slab surfaces from attracting condensation, particularly in garages, basements, or buildings in high-humidity regions.


Structural and Jobsite Durability

Built for Compression

The insulation maintains structural integrity under the weight of poured concrete, steel reinforcements, and foot or vehicle traffic during construction.


Tear- and Puncture-Resistant

The reinforced white poly layer stands up to jobsite handling, ensuring the insulation lays flat and remains effective before and during the concrete pour.


Energy Efficiency and Long-Term Savings

Reduces HVAC Load

By limiting heat loss through the slab, it lowers the demand on heating systems—resulting in reduced utility bills and longer HVAC equipment lifespan.


Delivers Long-Term Value

Unlike traditional insulation that may degrade over time, single bubble reflective insulation remains stable, ensuring consistent performance for the life of the building.


Easy and Efficient Installation

Installs Quickly Under Slabs

Lightweight and flexible, it rolls out smoothly across gravel beds or vapor-retardant sheets. Seam overlaps and taping are quick and effective for continuous protection.


Compatible with Radiant Heating and Mesh

The insulation can be installed before laying out radiant tubing or wire mesh reinforcement, integrating seamlessly into modern slab-building practices.


Environmentally Friendly Performance

Helps Reduce Carbon Footprint

Improving energy efficiency at the foundation level contributes to a more sustainable building, reducing reliance on fossil-fuel-based heating.


Recyclable Components

Many versions use materials that are recyclable or low in environmental impact, making them a smart choice for green building certifications.
