SPF blown-in loosefill insulation hybrid
Hybrid Attic Insulation: Superior Performance, Budget-Friendly Cost
Exotherm is aware that homeowners are consistently looking for superior attic insulation options. This is especially true for aging homes where a vapor barrier is absent or for bungalows that are more susceptible to the elements.
The SPF and loosefill insulation combination is one such application gaining popularity due to its cost-effectiveness and time-efficiency compared to using either material exclusively.
What is Hybrid Insulation and How Does It Work?
The hybrid insulation system is designed to provide maximum sealing and thermal resistance without the higher cost of a full Spray Polyurethane Foam (SPF) application.
The Two-Layer Installation Process
Air & Vapor Barrier (SPF Layer): The process begins by removing the existing insulation and applying a layer of 2lb medium density closed cell polyurethane foam that is two inches thick to the attic floor and perimeter. This layer is critical as it acts as both an air and vapor barrier while providing a thermal break.
Thermal Resistance (Loosefill Layer): To achieve the required final R-value, a layer of loosefill insulation (fiberglass or cellulose) is then added on top of the foam.
Why Homeowners Choose the Hybrid Application
Increasing numbers of homeowners are opting for the hybrid solution because they are looking for a more cost-effective alternative that delivers the trusted performance of spray foam.
Benefits of SPF Blown-In Loosefill Hybrid Insulation
The hybrid system delivers comprehensive performance and comfort for years to come.
Cost-effective: This application is more affordable than an all-spray foam application, making it a budget-friendly option.
Superior Air and Vapor Barrier: The spray foam layer seals any gaps or cracks in the attic floor, reducing air and minimizing moisture infiltration.
Energy-efficient: The combination provides excellent energy efficiency, minimizing heat loss and reducing energy bills.
Comfortable Living Space: This solution maintains even temperatures throughout the home, reducing drafts and cold spots.
Environmentally-friendly: The loosefill insulation is made of recycled materials, offering an eco-conscious option for insulation.
Frequently Asked Questions (FAQ)
What is the biggest advantage of hybrid insulation over full spray foam (SPF)?
The biggest advantage is cost-effectiveness. It provides the essential air and vapor barrier of SPF at a lower overall price point.
Does hybrid insulation create a vapor barrier?
Yes, the initial two-inch closed cell spray foam layer creates an effective air and vapor barrier, sealing the attic floor and preventing moisture infiltration.
Is hybrid insulation a good option for older homes?
Hybrid insulation is ideal for aging homes where a vapor barrier is often completely absent. The SPF layer seals and protects the attic floor, providing a superior solution for energy conservation.
What materials are used in the hybrid application?
The hybrid application uses two materials: 2lb medium density closed cell polyurethane foam (for the vapor barrier) and a layer of loosefill insulation (fiberglass or cellulose).
