Making a 90 Degree Angle with Duct Board
Duct board is a type of insulation material used in air conditioning and heating systems. It is made from fiberglass and is easy to cut and shape into various angles. Making a 90 degree angle with duct board is an important skill for anyone working on HVAC systems.
Step 1: Measure and Mark the Duct Board
Measure the length of the two sides of the angle you want to create. Mark the measurements on the duct board using a pencil or marker. Make sure that the marks are straight and even.
Step 2: Cut Along the Marks
Using a utility knife, carefully cut along the marks you made on the duct board. Make sure to keep your cuts straight and even. If necessary, use a ruler or straight edge to help guide your knife.
Step 3: Fit the Pieces Together
Once you have cut both pieces of duct board, fit them together at a 90 degree angle. Use tape or glue to secure them in place if necessary. Make sure that all edges are flush and that there are no gaps between the pieces.
Step 4: Secure the Joints
To ensure that your 90 degree angle is secure, use metal screws or rivets to fasten it together. This will help prevent any movement or shifting of the joint over time.
