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 of plywwood 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 should 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.

Ideal for covering concrete floors

 

Final flooring can be glued directly on top of the AL20

 

 

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 aluminum or copper 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

Foil Tape Rolls
Aluminum Foil Tape Roll

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.

Concrete Warning
Since aluminum is subject to attack by alkaline(s) it should NOT be allowed to come in direct contact with concrete or mortar. If aluminum is in contact with concrete (or even other metals) and is subject to wetting (as would happen outdoors), the aluminum should be insulated from the concrete, mortar, or metal by adding a barrier like: asphalts, paint, sealer, 6 mil plastic polyurethane sheeting or a neoprene adhesive. Use waterproofing concrete sealer if you know water might get in, on or through the concrete. If the aluminum foil shielded room has fire sprinklers installed, it is good idea to water seal the concrete floor, just in case of an intentional or unintentional water discharge.
