Insulating a Furnace Duct Insulating a Furnace Duct
The purpose of insulating furnace ducts within the house is to ensure maximum efficiency while decreasing the levels of energy used up by the house for heating purposes. In doing so one not only contributes towards an ecological and environmental way of living but also ends up saving a significant sum of money on your power costs. Studies have found that by saving even 1 degree of heat during the winter months can help cut your electricity bill by as much as 2 to 3%. Insulating the ducts helps to maintain the desirable temperature without allowing any air to enter or escape and disturb the equilibrium being achieved. Regardless of the seemingly advanced process and high degrees of complexity associated with insulating a furnace duct, the truth of the matter is that even a novice can do the needful with some strong tools and the right instructions.
Step 1 - The Insulating Process
Prior to beginning the insulation process one needs to take down the measurements of the dimensions of the furnace duct that needs to be insulated. The insulation sheets cannot be cut out until one has the exact dimensions noted down. Use the tape measure to get an accurate reading of the dimensions of the furnace duct that needs to be insulated. If the duct in questions is a circular one the tape measure should be used to gauge the length of the diameter of the duct. In the case of a square duct the measurements of all 4 sides need to be jotted down.
Step 2 - Cutting
Cutting the insulation sheets needs to be done with precision and care. The sheets should be spread out onto the ground and held in place by weights. Usually the sheets come in rolls of 4 feet by 100 feet. On an average one will need 4 foot pieces of the insulation material for the duct.
Step 3 - Dimensions
The third step is to cut the insulation according to the dimensions of the duct. Most experts recommend keeping an excess of 6 inches on each side to the dimensions to meet with any overlap needs that might arise while affixing the insulation pieces.
Step 4 - Wrapping Insulation
This step involves putting the insulation pieces in place. Each piece must be carefully wrapped and wound around the body of the duct. Use the stapler to fix the pieces in place. The staples should be attached at the seams of the insulating material.
The role of the aluminum foil tape strips comes into play in terms of securing the insulation and holding it together tightly.The tape should be applied cleanly and as evenly as possible to prevent it from cracking in the future.
