IRD-2,-3,-4 Specs

METU Insulated Access Door IRD-2, -3, -4

Sturdy, press-formed access door for insulated rectangular ducts or flat surfaces with insulation thickness

between ≈ 20 and ≈ 30 mm (IRD-2),
between ≈ 30 and ≈ 40 mm (IRD-3),
between ≈ 40 and ≈ 55 mm (IRD-4)

made of an inner and an outer cover plate which are pulled together thanks to two bolts and corrosion-resistant knobs. In doing so the duct wall is clamped evenly between the two access door covers.

In addition, the cut edge of the insulation is protected by a cover plate which is maintained in place and connected to the duct-wall without creating any thermal bridges thanks to a special rubber profile. The oval shape of the access door allows an easy installation into the opening.
