How to Insulate a Concrete Slab for Radiant Floor Heating

Published on: Dec 09 2013 by

Underfloor_heating_pipesIt is easy to see why radiant heat is becoming more common in new homes. Homes with radiant heat can easily maintain a healthy indoor air quality, because radiant heat does not stir up dust particles like many traditional heating methods do. Unlike forced air heating, radiant heat does not remove moisture from the air, and it travels evenly in all directions.

 

However, without insulation, much of this floor heat will be lost to the earth beneath your house. Poorly insulated floors result in wasted energy. This can mean higher utility bills as well as more energy use. By installing insulation properly, you will experience more of the benefits of a radiant heat floor.

 

Why EcoFoil?

EcoFoil’s under concrete insulation is designed specifically for placement under concrete and offers two major benefits:

• Laminated design protects the radiant barrier by isolating it from the concrete and prevents damage from moisture in the ground.
• Maintains high R-values even when in contact with soil.

 

Insulating a concrete slab for radiant heating is easy when you are planning an initial concrete pour. There is no special equipment needed to install radiant barrier insulation under concrete. Our under concrete barrier is designed for installation on rough grades. The reflective bubble surface is designed for heavy concrete pours and will easily survive normal foot traffic at a construction site.

 

How to install

1. Unroll the under concrete slab insulation, extending it approximately 6 inches up the side walls.
2. Seal the seams between rolls with a white adhesive insulation tape.
3. Adding 1″ of sand over the insulation helps to facilitate the drainage of any water, and may help to reduce curing time.
4. Pour concrete as usual once you have placed and sealed the insulation.
