Having your property insulation is a necessary step if you live in an area with cold weather. If you're looking to install insulation, stapling is one of the best methods for quickly and efficiently. Stapling the insulation will ensure it stays in place and prevent pests from entering. 


Here, we will discuss the types of staples you should use for insulation and some tips to staple insulation securely.


Do You Staple Insulation?


Yes, stapling is one of the most common methods used to secure insulation. Many insulation types, particularly fiberglass batts, come with tabs or flanges along the edges. These flanges are designed to be stapled to the wooden framing of walls or ceilings. By securing the insulation with staples, you ensure it stays in place and maintains its insulating properties.


\It’s important to note that some spongy or loose-fill insulation types don’t require stapling. Instead, they rely on containment, such as being blown into walls or attics, or held in place by vapor barriers. However, for traditional batt insulation with tabs, stapling is the go-to method.


What Staples for Insulation?


Choosing the right staples is essential for a secure installation. Aaron recommends using the Duo-Fast 50 or Arrow T50, and Rapid staples, both of which are ideal for this task. These staples are reliable and compatible with most staple guns designed for construction projects.


The key is to use staples that are durable and long enough to secure the insulation tabs without damaging them. Avoid flimsy or undersized staples, as they may fail to hold the material securely over time.


What Size Staple for Insulation?





Batted insulation comes in strips approximately 20 inches wide, but the size depends on the framing. These feature a paper or plastic back with nail fins on the insulation strip edges for easy attachment to framing studs. Insulation experts usually staple the nail fin to the wood for them to stay in place.


The recommended staple for stapling insulation is the 20-gauge, but you can also use the 19-gauge and the 23-gauge. At FastenerUSA, the top recommendations for stapling insulation are the Arrow T50/Rapid 11 and the 1/2" Crown Duo-Fast 50. The recommended staple size for insulation is 20-gauge, but you can also use 19-gauge or 23-gauge.


If you are going to add roofing insulation, a 19-gauge staple will create a tight seal and firmly hold the insulation in place. For this case, we recommend using the 3/8" Crown Rapid 19 roofing staples.


Tips to Staple Insulation



Stapling insulation is a relatively straightforward process. Here are some tips to help you staple your insulation:


1. Choose the right staples: Choosing the correct staple is a must. As we previously mentioned, if the crown of the staple is too narrow, it may not hold the insulation fin in place. Also, ensure the staple you selected is compatible with your staple gun.


2. Prepare the area: Clear any debris or obstructions from where you will be stapling the insulation. Remember to remove any sharp objects that could damage the insulation strip.


3. Measure and cut the insulation: Cut the insulation strip to the required length. Usually, the size required will be 20 inches wide, depending on the frame.


4. Start from the center: A great tip is to install insulation is to start by stapling the center of the insulation strip and then make your way out to the edges. This helps distribute the tension evenly and prevents the insulation from bunching up or becoming unevenly secured.


5. Space staples evenly: Placing your staples approximately 6 to 8 inches apart along the edges will ensure a secure attachment without causing any damage to the material.


6. Avoid over-stapling: If you over-staple the material, this will cause it to compress and reduce its effectiveness. The staples should only hold the insulation firmly without penetrating too deeply to damage it.


Even though the process doesn't sound so difficult, it is better to let professionals do it. Insulation experts ensure proper materials, prevent damage to the frame or insulation, and avoid using incorrect staples for a secure installation.


How to Staple Insulation in the Ceiling


Stapling insulation to the ceiling requires a bit more effort and precision due to the overhead angle. Here’s how to do it:


Choose the Right Insulation: Ensure your insulation has tabs or flanges designed for stapling.

Cut to Size: Measure and cut the insulation to fit snugly between the ceiling joists.

Position the Insulation: Hold the insulation in place with the tabs facing the joists.

Staple the Tabs: Use your staple gun to attach the tabs to the wooden joists. Start at one end and work your way to the other, stapling every 6 to 8 inches.

Avoid Gaps: Make sure the insulation fits tightly against the joists without gaps or sagging, which can reduce its effectiveness.



How to Staple Insulation in Walls


Stapling insulation in walls is similar to the ceiling but generally easier due to the vertical orientation. Follow these steps:


Prepare the Insulation: Cut the insulation to the correct length to fit snugly between the wall studs.

Position the Tabs: Place the insulation in the stud cavity with the tabs overlapping the wooden studs.

Staple Along the Edges: Use your staple gun to secure the tabs to the studs, ensuring a tight fit without compressing the insulation.

Seal the Gaps: Once the insulation is stapled, inspect the installation for any gaps or misaligned sections and adjust as needed.
