Lighthouse Insulation offers a wide range of insulation services for both residential and commercial buildings.
Whether a new building is being constructed or if walls are being renovated, an unfinished wall allows for a variety of different insulation options. There are advantages to each material, which we consider in order to suggest the perfect solution for you.
Fiberglass Insulation can come in continuous rolls (blankets) or it can be pre-cut (batts). The installation of fiberglass insulation must be done perfectly to avoid compression, heat bridging, and other complications that reduce its effectiveness. Even when installed correctly, fiberglass insulation naturally contains gaps and air pockets. These weaknesses can be circumvented by combining fiberglass with loose-fill or spray foam insulation.
Loose-Fill insulation fills the wall space much better than fiberglass. It can be blown into attics, finished walls, and other hard-to-reach spaces. It is ideal for tight areas because it easily conforms and fills each crevice. Loose-fill also provides acoustical insulation and is environmentally preferable.
Spray Polyurethane Foam (SPF) is the most effective and versatile material available. It can be applied in tight spaces, even between joists and rafters. It is sprayed on as a liquid and expands to tightly seal its container. Unlike fiberglass insulation which can have gaps and air pockets, SPF provides excellent resistance to air infiltration. It also provides greater energy efficiency, weather resistance, acoustical insulation, and even increased structural stability. The tight barrier controls vapor flow, preventing moisture buildup which can cause mold to grow. Our specially-trained professionals can apply spray foam with other insulation as a hybrid option that is both effective and cost-efficient.
Unsealed crawl spaces allow moisture from the earth to evaporate into the house. Water vapor absorbed by the wood in your home can cause wood rot and weaken the structure. In order to prevent this, we apply a vapor barrier to the ground and closed-cell Spray Polyurethane Foam on the exterior walls to create an encapsulated crawl space. This prevents moisture from the ground to rise and dampen the area. It also insulates the house from rigid ground during winter. While other solutions to moisture build-up such as crawl space vents can let water vapor flow to the outside, encapsulating the space is the best way to ensure it stays warm and dry.
Retrofitting your walls with Spray Polyurethane Foam is a discrete way to fortify your insulation without tearing down walls. The foam is pumped through a small hole in the wall, where it then expands to seal every gap in the space. It hardens to create a tight barrier that is thermal, moisture, and sound resistant. Homes Retrofitted with SPF are much more energy efficient and have lower utility bills.
