Aluminum Foil Tape-Construction Tape

2016-07-08

When comparing foil tape to choose which product to use for your project, there are several factors you should look at to determine which tape is the best.

Thickness is important because it means the tape is more durable, but also heavier, so think about what this means to your project.

Peel Adhesion means how easy it is to remove this tape. Does your project require a more permanent seal?

Shear Strength refers to how easy the tape is to cut. Many household tapes, like common duct tape, tear across without the need for scissors and this is not something you want on your building, but you probably don’t want something that takes too much time for the builder to cut, either.

Tensile Strength refers to how much stretching a tape can withstand before it tears.

You may also need to look at the temperature range, depending on where the tape will be used.

There are several kinds of construction tapes, also known as sheathing or seaming tape, but it is primarily used for enhancing the building envelope to block out air and moisture. It is placed over housewrap seams and sheathing joints, as well as other areas where air or water might penetrate.

Sheathing tape is generally made for using as a vapor seal on all sheathing materials. It works in a wide range of temperatures and bonds well with other tapes, foams and all major housewraps. It also works as an excellent barrier on polyethylene film.

In a word, construction tape is designed to reduce air infiltration, improve the effectiveness of insulation and reduce costs associated with heating and cooling. It provides the versatility for seaming, splicing, sealing or repairing moisture barriers inside and out, including sheathing, and moisture and weather resistant barriers.

HVAC tape is an insulating, non-conductive tape which is used for insulating electrical wires and other conductors of electricity of HVAC systems. It is usually made of vinyl or plastic. And the tape is usually safety tested to guarantee its non-conductivity and temperature resistance for use as insulation.

Aluminum foil tape is used for applications that require conductivity, reflectivity or chemical and moisture resistance. It is also resistant to weather and fire. Duct tape is a cloth-backed adhesive that gets its color most often from powdered aluminum pigment and should not be confused with fire-resistant aluminum foil tape.

Flashing tape is made of a sturdy material, often aluminum, with a thick adhesive on the back side. It is used to seal windows during installation. Prior to the invention of flashing tape, builders used heavy caulk around windows, but caulk dries out over time and becomes useless at moisture prevention.
