Proseal Spray Foam is a popular and effective way to add insulation and create a seal in your home. Its air-sealing properties help keep energy costs low, while improving comfort and reducing unwanted noise from the outdoors or neighbors. But what exactly is it made of and how does it work? South Central Services receives this question from many of our customers, and we’d like to provide some helpful information.

Spray polyurethane foam (SPF) is a composite material created by two liquid chemical components that undergo a chemical reaction when they meet at the tip of a spray gun. The chemicals are kept in separate hoppers or tanks and transported through gas pressure or a liquid until they are ready to meet at the tip of the spray gun, at which point they react to create the plastic foam. These chemicals are typically called the A side and the B side, but each spray foam manufacturer has its own proprietary blend of chemicals.

The Science Behind Proseal Spray Foam Insulation

When choosing your spray foam insulation, look for a product that uses a blowing agent with low global warming potential (GWP). The HFCs used to be commonly found in many products, but there are now a number of manufacturers using alternative blowing agents that have significantly lower GWPs, including Ecomate CM01 by BASF and Genyk Boreal Nature by Gensun. These newer, patented ingredients are not as harmful to the environment as the former HFCs, and are also safer for workers to use in their application.

Insulation contractor is essential for maintaining building durability, energy efficiency, and indoor air quality. Moisture is one of the biggest threats to insulation performance because it reduces thermal resistance and can lead to mold growth, structural damage, and poor indoor conditions. These advanced insulation systems are designed to prevent water absorption while maintaining strong thermal performance.

In many buildings, moisture enters through walls, basements, roofs, and poorly sealed joints. When insulation absorbs moisture, it loses its ability to trap air effectively, which reduces its efficiency. Over time, this can lead to energy loss and damage to building materials. Moisture-resistant insulation helps solve this problem by combining thermal protection with water resistance.

How Moisture Resistant Insulation Works

One of the most common moisture-resistant insulation materials is rigid foam board. These boards are designed with closed-cell structures that prevent water penetration. They are commonly used in basements, exterior walls, and foundation areas where moisture exposure is high. Spray foam insulation is another effective option because it expands to fill gaps and creates an airtight, moisture-resistant seal.

Vapor barriers are also used alongside insulation systems to block moisture from entering wall cavities. These barriers are typically installed on the warm side of insulation to prevent condensation buildup. Proper installation is critical because incorrect placement can trap moisture instead of blocking it.

Mineral wool insulation is another material that offers good moisture resistance while also providing fire protection and soundproofing benefits. Unlike traditional fiberglass, mineral wool does not absorb water easily, making it suitable for damp environments.

Proper drainage and ventilation systems also support moisture-resistant insulation. Without adequate airflow, trapped moisture can still cause damage even in resistant materials. This is why building design must consider both insulation and ventilation together.

The importance of moisture control is closely related to building science principles. The study of building insulation explains how insulation materials help regulate heat transfer while also influencing moisture behavior. Moisture-resistant systems are essential for long-term structural health and energy efficiency.

Unlike fiberglass insulation which compresses or loses effectiveness over time, spray foam is resilient and retains its shape. This allows it to fill the spaces between studs and walls, sealing leaks and crevices that would otherwise go unnoticed. This is especially important because moisture entrapment can lead to costly issues like mold.

High-quality spray foam insulation is made from polyurethane, which is an eco-friendly, non-toxic material that’s gotten even greener in recent years as manufacturers have found ways to reduce the amount of blowing agents they use to help it take shape. It’s a highly versatile product that can be used in new construction homes, pole barns, or existing buildings in need of insulation.

Home Insulation 101: Why Tulsa Homeowners Choose Spray Foam

The biggest benefit of spray foam insulation is the powerful energy savings it can provide. It creates a custom air barrier and stops air infiltration that causes drafts, which in turn lowers HVAC usage. This can significantly lower energy bills, resulting in an immediate payback on the initial investment.

This is due to the fact that the air barrier created by this product restricts convective heat transfer from the outside air to the indoors during heating months and vice versa during cooling.

Foam also blocks the movement of polluted outdoor air into buildings, allowing only clean indoor air to enter. This results in a healthier environment for building occupants, as well as reduced indoor allergens. This can also reduce the frequency with which a building’s climate control systems must be used, which further cuts down energy costs.
