10 Tips to Applying Spray Foam Insulation Over Wall Studs
Here at SprayWorks Equipment, we provide all the tools needed to complete a project for insulating cavities with wall studs. We also provide on-site and online training and education to prepare individuals or businesses for any project.
Spray foam insulation offers many benefits when used to fill your wall space and cover wall studs, which makes it a popular choice for commercial and residential construction projects. Tips for utilizing spray foam to cover exposed walls and wall studs include:
- Follow safety precautions – The first step to any insulation project is to make sure you have all the right protective gear and equipment. Specifically, spray foam can be extremely harmful if it comes into contact with the skin or eyes, so it’s important to make sure you have goggles, gloves, and a mask.
- Prepare the area – Before starting a project, it is crucial that the area is cleared of any debris, dust, dirt, and damageable furniture. Prep the space by covering any open floors with drop cloths or plastic sheeting. This will help protect your surface from overspray.
- Adhere to local codes and regulations – In some cases, there may be local codes and regulations regarding insulation materials and insulation methods that you will need to be in compliance with. Check with the city or local building management to clear the project before starting.
- Select the right spray foam – There are two main types of spray foam insulation: closed-cell and open-cell foam. In most cases, closed-cell foam will be favorable when working with wall studs as it provides a higher R-value and acts as a vapor barrier.
- Start at the bottom – There are many techniques used in spray foam application, but specifically when filling wall cavities and covering the adjoining wall studs, it is recommended to start at the bottom to prevent air pockets from forming. Air pockets can cause excess insulation to leak, causing negative effects.
- Evenly fill cavities – In addition to starting at the bottom, it is crucial that the insulation is applied consistently and evenly throughout the wall cavity. Failing to do so can result in overfill which can cause damage to the wall and bulging from the excess insulation.
- Allow for expansion and curing time – Depending on the type of spray foam that is used, there will be different recommended curing and expansion times. It is important to follow these instructions to allow time for the insulation to settle and expand in the necessary areas.
- Seal the gaps – When working with spray foam in walls, you will often come across gaps for electrical outlets and pipes that need to be sealed off before applying the insulation. It is recommended to use foam backer rods to support the foam between the gaps.
- Trim excess foam – After allowing time for the spray foam to cure and settle, you’ll want to trim any excess foam with either a foam saw or a utility knife depending on the amount of foam left over. Removing the excess will eliminate the risk of bulging and allow for an enhanced appearance while making it easier to apply a finish.
- Consider temperature and humidity control – Often overlooked, the temperature and humidity in a space can affect the curing and settling process of the spray foam insulation. It is ideal to insulate wall studs in a climate-controlled environment.
Benefits of Using Spray Foam on Wall Studs
As noted above, spray foam insulation provides many benefits and is the preferred material for many construction projects. Not only will spray foam insulation improve your living or working environment, but it is an innovative solution that offers long-lasting benefits including the following.
Enhanced Air Sealing
Spray foam insulation acts as an effective air barrier that prevents drafts and air leakage from walls. Not only does this enhance your air quality, but it reduces the presence of pollutants, dust, and allergens.
Moisture Control
For an indoor environment and a project involving wall cavities, wall studs, and spray foam insulation, the drier the better. Specifically, closed-cell spray foam is a leader in moisture control. It is designed to eliminate moisture buildup within the wall and reduce the risk of structural damage and mold growth.
Maximized Durability
Compared to other insulation materials, spray foam is extremely durable and can last a long time if installed properly. Other materials are known to settle over time, but spray foam maintains its integrity and insulation properties indefinitely.
Insect and Pest Deterrent
In addition to closed-cell spray foam’s moisture control benefits, it also serves as a barrier for insects, helping to prevent pest infestations within walls. These types of infestations can lead to major structural damage, so keeping your space clear of them is key.
