When it comes to insulating walls, most people think of fiberglass batt insulation. For years, fiberglass batt insulation was the only way to insulate walls. Today’s construction technology has many other options! One cost-effective and the energy-efficient option is the blown-in-wall system.
The blown-in wall system provides a high-efficiency energy blanket of insulation at a fraction of the cost of spray foam insulation. This system is installed in open cavities during the construction or remodeling process and can be used in residential or commercial buildings. The blown-in wall system gives homes a seamless, thermally efficient blanket of insulation that completely fills any void in the wall cavity.
Here’s how it works:
- Fabric mesh is installed across the open wall cavity. It is tacked to each stud in the wall assembly.
- Loose-fill fiberglass insulation is blown behind the fabric mesh. It is installed at a density that fills all voids in the wall cavity.
- The penetrations in the mesh are sealed to hold the product in place.
There are many benefits to installing the blown-in wall system in your next project. The blown in wall system offers:
- Higher R-values than traditional fiberglass batt insulation, saving on heating and cooling expenses.
- Reduced air infiltration. National laboratory tests have shown a 68% reduction in air infiltration when installing a blown-in wall system over fiberglass batt insulation.
- TAKE ENERGY EFFICIENCY ONE STEP FURTHER! Air seal each wall cavity prior to installing a blown-in wall system to further increase efficiency!
- Excellent sound control. Because loose fill fiberglass insulation completely fills the wall cavity, noise transfer is reduced.
- Does not settle. Because the insulation is dense packed, there’s no chance of it setting and affecting r-value.
