"Am Tape" gasket tape is an excellent air-tight gasket for use in air-duct systems. It is made of fire-retarded nitril rubber foam. With its 100% closed cell, elastic and highly flexible properties. Service

O Otemperature range -40 C to +85 C. We recommend the use of the appropriate gasket to ensure performance in accordance with DW/TM1 test results.

Inside of Duct

Directionof Cut

Cut two lengths of profile to suit the duct width less 28 (W),and two lengths to suit

the duct height less 28 (H). Note: outside dimensions of the duct are to be used,

not internal.

For best results use a circular cut off saw with pneumatic vice. If any burring has

occurred during the cutting of the flange, this must be removed before assembly.

Insert four corners into the flange form a rectangle

frame as shown. Care must be taken to ensure the

legs of the corners are fully inserted into the flange,

the 'nose' on the corner faces away from the duct

on which the frame is to be fitted. To comply with

DW/144 corner pieces should be fixed into the

flange. This can be done with a press tool.the

cutting of the flange, this must be removed before

assembly.

The frame is now ready to be fitted to the duct. Starting in one corner, the frame

should be firmly tapped home by working away from this corner. On larger ducts a

straight edge can be used to ensure the frame is on 'flat'.

The frame can be attached to the duct by various methods, spot welding ,rivet or

clinch. Spacing for fastenings to be as DW/144 table 5. A fixing at a maximum of

50 mm from each comer is recommended, this will give additional strength during

the installation.

Any burrs caused during the drilling for fixings should be removed from all

surfaces before finally fixing the frame to the duct. Sealant should be applied if

any method of fixing pierces the duct..

When the frame is securely fixed, a fillet of mastic needs to be run along the cut

end of the flange on the inside of the duct.

Sealant must be
