Spray foam insulation (SPF) is a great way to improve the energy efficiency of metal buildings. It is an effective solution for improving the structural integrity and rigidity of metal walls and roofs. It also helps regulate temperature and reduce condensation.
In this article, we will discuss the cost, pros and cons, and benefits of using spray foam insulation in metal buildings.
What is Spray Foam Insulation?
Spray foam insulation is a powerful barrier that restricts airflow through walls, floors, and ceilings. It seals off spaces around light fixtures and electrical outlets, as well as where walls meet windows or doors - which makes it ideal for new construction projects, attics, crawl spaces, and rim joists.
Not only can spray foam be used in new construction, but it is also suitable for existing homes, commercial buildings, and metal buildings, as long as all cavities are accessible. The incredible thing about this material is that it will never lose its structure. Unlike other insulation materials which compress or sag over time, spray foam will remain sturdy and secure even after installation because it fills any crevices and cracks present.
Spray foam insulation is divided into two categories: Open and Closed cell.
Open Cell
Open-cell foam is a softer and more flexible material due to its cells being deliberately left open, rather than fully encapsulated. This unique design allows for greater elasticity and malleability in the foam compared to other materials. It is typically used during the rough-in stage of construction to fill cracks and voids in walls and floors, especially voids around plumbing and electrical wiring.
Closed Cell
Closed cell foam is constructed of cells that are tightly pressed together to prevent air and water from passing through. This results in a sturdy and dependable material – one that is far more reliable than open-cell foam due to its hermetic structure. This is the preferred insulation for metal buildings.
Benefits of Closed Cell Spray Foam Insulation in a Metal Building
Increases Structural Integrity and Rigidity
The high compressive strength of closed-cell spray foam makes it ideal for use in metal structures because it adds additional strength to walls and roofs. It also provides additional protection against extreme weather conditions like heavy winds or hail storms.
Reduces Outside Noise
Closed-cell spray foam has excellent soundproofing properties that can help reduce noise pollution from outside sources such as traffic or construction sites nearby your building.
Temperature Regulation
Spray foam insulation can regulate the temperature inside your building more effectively than traditional fiberglass or cellulose insulation materials. The airtight seal created by spray foam helps keep cool air inside during hot summer months and also prevents warm air from escaping during cold winter months - for lower energy bills throughout the year!
Reduces Condensation
It helps prevent condensation from forming on interior surfaces like walls and ceilings due to its airtight seal capabilities - this can help protect against mold growth which can cause serious health issues if left untreated! Additionally, because closed-cell spray foam has high compressive strength, it will increase the structural integrity and rigidity of metal buildings
Pros of Closed Cell Spray Foam Insulation for Metal Buildings
- The R-value of spray foam insulation is higher than that of other insulation materials. This means that it provides better insulation by reducing heat loss or gain.
- Spray foam insulation is easy to apply and can be done quickly. It does not require special equipment or skills which makes it a cost-effective solution.
- Spray foam insulation provides an airtight seal that prevents heat transfer through gaps and cracks. This can significantly improve the energy efficiency of the building.
- It can improve indoor air quality by preventing the infiltration of dust, pollen, and other allergens into the building.
Cons of Closed Cell Spray Foam Insulation for Metal Buildings
- Spray foam insulation can be more expensive than other forms of insulation. However, it is a long-term solution that can save money on energy bills over time.
- It usually requires professional installation. This can add to the initial cost of the project.
- The application of spray foam insulation can be messy, and excess foam may need to be removed manually.
Costs of Spray Foam Insulation
The installed cost of spray foam insulation varies, with an average cost of $1.25 - $4.50 per square foot.
- The overall size of your area will determine the total cost, as larger spaces are more expensive to insulate.
- A thicker coat of insulation costs more than thinner layers - so when budgeting always factor that into consideration.
- The labor fees vary depending on how intricate the area is and where you live; typically between $0.44 - $1.55 per foot should be accounted for within your budget.
Insulating Your Metal Building with Spray Foam - D.I.Y.
Insulating an entire metal building may be an aggressive goal if you are trying to do it in your spare time. However, sealing up the joints, edges, and other openings can easily be done with a few tools from Fastener Systems. Metal building construction tends to leave cracks and openings that are too large to seal with standard caulking products.
Using FROTH-PAK™ Foam Insulation Kits will give you professional results while saving time. The kits come complete with 2-part foam, a 9' hose and gun assembly and cone nozzles. These kits can also be used to insulate your entire building!
Fastener Systems Can Help Insulate and Seal Your Metal Building Against the Elements
Whether you are sealing a few gaps in a wall or insulating an entire metal building with spray foam, FSI carries the tools and sealants needed for almost any project. Our line of DuPont sealants includes individual cans for around the shop as well as larger systems for a DIY spray foam insulation project.
