Are you looking for a reliable way to seal your ductwork? If so, silicone caulk and duct sealant are both excellent options. However, it's essential to remember that both must be protected, coated, and supported with aluminum tape for optimal efficiency. This will guarantee that the joints of the ducts are solidified and won't separate or slide in any direction. To further secure the joints, you can insert short self-tapping duct screws through the two pieces of the joint. This will bring everything together and provide an additional 26% efficiency.
