Installation Methods

 

4" Electrically Conductive Tape with 2" minumum overlap (Recommended)

EC Tape

 

 

Butt Jointed with 4" Electrically Conductive Tape

 

 

Non-Conductive Tape

 

 

EMI-Shield AL2.5 & AL5 is applied like wallpaper, covering all surfaces: floor, walls and ceiling. Other than normal cleanliness, and dust free, no special preparation is required.  Typically the foil is sandwiched in between the 1st and 2nd layer of sheetrock. Ideal for commercial construction architectural RF shielding.Foil glued in-place or PSA Available.Bare Foil or with Non-Conductive Pressure Sensitive Adhesive (PSA).

For maximum effectiveness, seams may be taped with electrically conductive adhesive foil tape.

We recommend a minimum 2.0" overlap of the foil and a minimum of 4' wide electrically conductive adhesive foil tape.

Do not solder or weld EMI-Shield AL2.5 or AL5

AL20 Lightweight Semi Rigid Aluminum Foil Panels for EMI / RFI Shielding



Semi Rigid Aluminum Foil Panels for Shielding

 

We recommend AL20 being cut or shaped

 with electric or pneumatic metal nibbler

 

Must be Shipped Palletized by Truck

 

Ideal for covering concrete floors

 

Final flooring can be glued directly on top of the AL20

 

 

EMI-Shield AL20 is applied like lightweight paneling, covering all surfaces: walls and ceiling. Other than normal cleanliness, and dust free, no special preparation is required.

The panels are not self supporting.

The foil panels may be screwed (self drilling screw recommended) (wall systems) or glued in-place (floor systems).

For maximum effectiveness, seams should be taped with 5 mil Aluminum or 5 mil Copper (recommended) electrically conductive adhesive foil tape.

For floor installations we recommend  butt jointing the panels and taping the seams with 4" wide electrically conductive foil tape. 6" wide non-conductive adhesive foil tape can also be used, but not recommended.

For wall installations the AL20 panels can be butt jointed or overlapped.

AL5 Aluminum Foil Seaming Tape for EMI / RFI Shielding





EMI-Shield AL5 Tape is applied like any tape with a release. The tape is used to RF seal the seams of foil or foil panels.

The 4" wide, electrically conductive PSA is ideal for sealing the seams.

The 6" wide, non-conductive PSA is used to frame out all the corners and intersections between walls, ceiling and floor, before the foil rolls are applied.

The 1" wide electrically conductive tape is used to electrically bond all foil rolls, if they were applied with non-conductive PSA.
