Insulating your metal building may not have crossed your mind when you first drafted the construction costs. However, if you live in an area where the weather fluctuates frequently, insulation might be your saving grace.
While there are many ways to insulate a metal building, using spray foam is one of the most budget-friendly and convenient ways of going about it. You’ll enjoy long-term benefits since it’s a quality-over-quantity option.
Why You Should Insulate Your Metal Building
Insulating your building comes with several advantages. Of the many you will come across, here are the three that will help you see why this will be a worthwhile undertaking.
1. Stabilize temperatures
An ideal building means human beings are comfortable being in it, no matter how long they spend indoors. This means you need a constant and accommodative temperature.
If you live in an area where winter and summer environmental conditions are on the extreme, you understand the importance of ensuring that a building’s temperature remains constant.
Insulating a metal structure regulates the building’s temperatures such that extreme cold or heat does not get in. Since iron is a high conductor, it gains and loses heat drastically. This is the same effect you will have indoors for a non-insulated metal building.
However, a building insulator is a slower conductor meaning it will keep indoor temperatures from changing whenever a change happens outside.
2. Prevents moisture
When the air is warm and moist in a room, it rises and then condenses around its structure. This causes moisture accumulation that contributes to mold and mildew growth.
If the building’s structure is an ideal conductor such as metal, the process is faster, meaning you will always have a sweaty building. Such constructions don’t last, and soon the metal will become rusty.
Insulating your metal building makes the process much slower. Since the foam will keep the environment warm, moist air will not have room for condensation, thus preventing moisture accumulation.
3. Cost savings if you are heating or cooling the space
You could be thinking that heating or cooling the space is also a viable option. However, just think about how high your utilities will cost if you use a heater or cooler throughout the day.
This will be more outrageous when the temperature spikes on both extremes. Insulating your building allows it to self-regulate its indoor temperatures.
If you still need heating equipment, you will not need to overwork it since most of the work happens naturally. This consequently saves you on the cost of utilities.
Types of Spray Foam Insulation
Spray foam insulations come in two types: open-cell and closed-cell foam insulation.
Open-cell Spray Foam Insulation
This is the less dense version of the two. It is a bit permeable to vapor, and application is efficient on the walls, ceiling, and roofs. The foam uses water, carbon dioxide, or soybean oil as its blowing agent.
Open-cell spray foam has a lower R-value compared to its counterpart. Filling a two by four cavity creates about R-13, meaning it has about R-3.5 to R-3.6 per inch. You will need to accompany its installation with a vapor retarder to make it more effective.
It is durable, safe, and offers excellent insulation capabilities plus cheaper than closed-cell spray foam.
Closed-cell Spray Foam Insulation
If you are looking for an all-in-one insulation material, then closed-cell spray foam is an ideal option. It is way better compared to other insulation materials such as fiberglass and cellulose.
Its R-value is as high as R-6 to R-7 per inch. This makes it an excellent insulating material for walls, roofs, ceilings, and even slabs. It is perfect for resisting moisture, vapor, and creating an air barrier.
The foam also adds to the structural strength of the surface it’s installed upon. For this reason, you can also use it for air leaks at the top plate and rim joints partitions.
Spray Foam Preparation Steps
Prepping for spray foam insulation is as essential as the application process. It ensures nothing gets damaged in the process, all precaution matters remain attended to, and you get the best out of the entire application experience.
1. Cover all doors, windows, shower tubs, and any other surfaces that will not need spray foam with protecting plastic sheets.
2. Remove all items that will obscure the working space or get damaged in the process.
3. Remove all older insulation in the crawl space, rim joint, and attic. This keeps the space healthier and ensures easy and effective application.
The rule is simple during this process; move it if possible, else cover it.
Why is Spray Foam more Superior than Other Types of Insulation?
Mineral wool, fiberglass batts, and other traditional insulation materials such as foam board and rolls might be viable options. Still, you will not enjoy as many benefits as using spray foam. Here is why spray foam is more superior:
The closed-cell spray foam has twice the R-value as most other options, making it a more substantial choice. While the rest have R-values ranging from R-2 to R-4, spray foam extends to R-6 and R-7, making it a superior material.
Another advantage you will enjoy with spray foam in comparison to the rest is its air seal abilities. In areas where winter is intense, partitions and building edges accumulate a lot of ice. Closed-cell spray foam keeps this from happening by insulating these areas and covering up the divisions.
Requires less depth
One of the advantages you enjoy with quality products is that you won’t need to use too much to get the effect you want. This is what happens when you choose spray foam over other insulating materials.
Spray foam is already dense, thus requiring less depth in the application. You spend less time on work and enjoy maximum benefit afterward.
Insulating a metal building should be a priority, as serious as having windows and doors. Spray foam is an excellent option for metal building insulation, and you will also enjoy noise insulation by using it. The more comfortable the internal environment, the more productive you will be working in the space.
