Over Slab Superior to In-Slab Radiant
Radiant heat has been used in cementitious slabs since the times of the Romans providing amazing, comfortable heat. However, many building design considerations have changed … so too with radiant slab heating. It has become increasingly evident that an over-slab assembly like InsulHeat makes more sense in modern buildings than in slab radiant heat. Why?
Why Choose InsulHeat?
- Much Lower Mass: InsulHeat is lightweight and fast responding.
- Better Response: InsulHeat applies insulation and heat where it’s needed.
- Better efficiency: Aluminum surface provides high heat transfer rate.
- Fast Installation: Insulheat installs far faster and is more effective than installing insulation under the slab, at the slab edge and installing termite guards in many regions.

Conventional Radiant In-Slab Heating Issues
Problems with radiant concrete slabs center around poor response time, heat loss and lower total efficiency, construction challenges and structural issues in seismic design areas. In slab radiant has PERT tubing in the middle of the slab meaning that the whole slab needs to come up to temperature before heat is radiated to the room for the floor surface.
|Traditional In-Slab Radiant||InsulHeat Radiant Panels|
|Response Time||Long Response Time
It takes a long time from start up for heat to penetrate a large slab and start radiating to the surface at a useable temperature. This results in the well-known issue of poor system response time in both heating up and cooling down, if solar gain occurs.
|Fast Response Time
Aluminum is 1,500 times more conductive than wood and 250% more conductive than concrete. InsulHeat is laminated with a highly conductive aluminum coating allowing for a far faster response time than traditional in-slab concrete.
|Heat Loss||Rapid Heat Loss|
Many tests have been conducted over the years regarding slab insulation. The issue of downward heat loss and the thermally destructive introduction of water below the slab is well known. What has not had as much attention is the far greater problem of lateral edge slab heat loss, which is actually a larger problem.
|Retains Heat Longer
The InsulHeat panel substrate is constructed with highly durable EPS foam. This insulating layer creates a barrier that helps prevent heat from sinking beneath the floor. Heat retention for InsulHeat is 4X – 10X greater than traditional in-slab systems. This lower heat loss also provides significant energy savings.
The multiple downsides of in-slab radiant results in very poor efficiency. This includes poor heat retention, higher heat loss, and wasted energy as heat sinks into the foundation or subfloor — giving users only a fraction of the radiant heat the system produces.
InsulHeat directs heat where you want it — upwards. The combination of durable insulating EPS foam and conductive aluminum laminate provides an insulation barrier beneath the panel. This prevents heat from sinking uselessly into the subfloor, delivering comforting radiant heat faster and far more efficiently than in-slab radiant.
|Moisture Resistance||Prone to Moisture Issues|
Avoiding current or future incursions of water under a slab is not a certain construction bet. If moisture enters under a radiant slab, the system heat loss increases significantly.
|Highly Moisture & Mold Resistant
Water is a great conductor. InsulHeat can be installed with moisture or water proofing adhesives that provide an excellent vapor barrier preventing the buildup of moisture and mold.
|Seismic Concerns||Vulnerable to Seismic Activity|
Along the Western United States, many engineers no long permit radiant PEX tubing in their structural concrete slabs due to seismic code design requirements.
|Compatible with Modern Seismic Codes|
Post tension slabs cannot have penetrations, thus a glued/insulated topping panel is an ideal solution. Our modular panel system meets modern seismic engineering standards.
