Spray-applied polyurethane foam insulation, also known as SPF insulation, is a popular choice for insulating buildings due to its unique properties and application method. SPF insulation is a two-component liquid system made of isocyanate and polyol resin. These components are mixed and sprayed onto a surface, where they undergo a rapid chemical reaction that expands the mixture into foam.
In this article, we will explore the types of SPF and the advantages they provide over traditional insulation materials. We will also discuss how SPF insulation can contribute to energy efficiency and the overall comfort of buildings.

Types of Polyurethane Foam Insulation
There are two main types of SPF insulation:
- Closed-cell: This type has a closed-cell structure with millions of tiny gas bubbles trapped within the foam. It offers excellent thermal resistance, water resistance, and some structural support.
- Open-cell: This type has a more open-cell structure, allowing for some air and moisture permeability. It offers good thermal resistance but less water resistance compared to closed-cell foam.
How Does Polyurethane Foam Insulation Help in Soundproofing?
Polyurethane foam insulation can be useful for sound control. These unparalleled sound control solutions will reduce noise while also enhancing structural integrity, energy efficiency, and general building comfort.
The open-cell variety of polyurethane foam has a more open structure that can trap some sound waves, converting their energy into heat and reducing noise transmission. However, closed-cell foam, which offers better thermal insulation, is denser and provides less sound absorption.
Polyurethane foam excels at sealing gaps, cracks, and holes in walls and ceilings. These small openings can act as pathways for sound to travel, so sealing them can lead to noticeable improvements in soundproofing.
How is Polyurethane Foam Insulation Energy-Efficient?
Polyurethane foam insulation boasts excellent energy efficiency due to its exceptional thermal resistance and air-sealing capabilities. Here’s how it makes a difference:
High R-Value
Polyurethane foam, both closed-cell and open-cell, offers a superior R-value compared to many traditional insulation materials. R-value indicates a material’s ability to resist heat flow, with higher numbers signifying better insulation. This translates to less heat transfer through walls, ceilings, and attics, keeping your home cooler in summer and warmer in winter.
Air Sealing
During application, the foam expands to fill cracks, gaps, and voids around electrical outlets, pipes, and other penetrations. These air leaks can significantly impact energy efficiency, as conditioned air can escape through them. Polyurethane foam effectively seals these leaks, minimizing drafts and unwanted air infiltration, and reducing the strain on your HVAC system to maintain comfortable indoor temperatures.
By minimizing heat transfer and air leaks, polyurethane foam insulation helps regulate indoor temperatures naturally. This translates to lower energy consumption for heating and cooling your home, resulting in significant cost savings on your energy bills.
How Does Polyurethane Foam Insulation Improve Indoor Air Quality?
Polyurethane foam excels at sealing air leaks. These leaks allow pollutants like dust, pollen, and other outdoor allergens to enter your home. By effectively sealing these gaps, polyurethane foam can minimize the infiltration of outdoor contaminants, potentially improving indoor air quality for allergy sufferers. The closed-cell polyurethane foam acts as a vapour barrier, like polyurethane coating or epoxy waterproofing, reducing moisture transmission within walls. Excess moisture can lead to mold growth, which can trigger respiratory problems. By controlling moisture migration, closed-cell foam can help prevent mold issues and contribute to a healthier indoor environment.
During and after installation, some SPF products might emit volatile organic compounds (VOCs). These gases can irritate the eyes, nose, and throat, potentially impacting indoor air quality. It is important to choose low-VOC or certified foam products to minimize concerns related to emissions.
