Technical Information

Applications of Single Bubble Reflective White Poly Insulation

Residential Applications

Slab-on-Grade Homes

Used beneath the concrete slab in slab-on-grade home construction, this insulation provides a critical thermal break between the structure and the ground. It helps retain heat indoors during cold seasons and improves overall energy efficiency.

Radiant Heated Floors

Perfect for homes with radiant floor heating systems, this insulation reflects heat back into the living space rather than allowing it to dissipate into the ground. It maximizes system efficiency and delivers more consistent comfort across the slab surface.

Finished Basements

Installed under concrete basement slabs, it helps prevent cold floors and moisture intrusion. It’s especially useful in finished basements where floor comfort and long-term protection against ground vapor are priorities.

Garages and Workshops

Whether heated or unheated, concrete floors in garages and workshops benefit from the added moisture barrier and thermal layer this insulation provides. It supports a more stable interior climate and reduces slab condensation.

Commercial and Industrial Applications

Warehouses and Distribution Centers

In large-scale facilities where slab floors dominate, under-concrete insulation helps regulate interior temperatures and lowers the load on HVAC systems. This is especially valuable in temperature-controlled environments or where personnel are working near ground level.

Commercial Offices and Retail Spaces

For commercial buildings with slab foundations, the insulation layer improves occupant comfort and supports energy code compliance. It also enhances the performance of radiant floor systems in lobbies, corridors, and open retail areas.

Cold Storage Facilities

In walk-in coolers, freezers, and cold storage rooms, under-slab insulation is critical to prevent ground frost heave and maintain temperature control. This insulation supports the performance of floor-based cooling systems and minimizes energy loss.

Agricultural and Utility Buildings

Pole Barns and Steel Structures

In agricultural buildings with poured concrete floors, this insulation reduces upward moisture migration, making interior environments more usable and protecting stored goods or machinery.

Animal Housing

Used under concrete floors in kennels, stables, or poultry houses, the insulation helps maintain a more comfortable floor temperature for animals and prevents dampness from rising through the slab.

Greenhouses

Helps insulate slab floors in greenhouses and hydroponic facilities, retaining heat and reducing energy consumption during colder months while also acting as a moisture barrier.

Specialty and Custom Applications

Shipping Container Foundations

When shipping containers are placed on concrete pads, this insulation can be installed under the slab to reduce thermal bridging and control moisture—especially in permanent or semi-permanent builds.

Modular and Prefabricated Structures

Supports energy-efficient slab installations in modular or prefabricated construction. Enhances thermal regulation and simplifies compliance with building insulation requirements.

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.
