IRD-DW2

IRD-DW2 Insulated Access Door Solution

Solution for double-wall rectangular ducts with very thick insulation. 

Two separate RD Access Doors are installed, one for the inner duct and a second one, preferably larger, for the outer duct. 

Excellent insulating properties, since there are no thermal bridges.

Please observe the minimum insulation thicknesses below.

Availability and prices upon request.

  1. Inside duct wall
     
  2. Duct wall or outer skin made of aluminum
     
  3. Insulation thickness (please pay attention to the minimal insulation thicknesses)
     
  4. RD access door
     
  5. Second RD access door (can be made of another material, like aluminum in case the outer duct is also made of aluminum)
     
  6. The air pocket trapped between the two access doors offers excellent insulating properties. To avoid any convection currents insulation chunks can be stuffed into the hollow spaces between the access doors.

For this access door version two independent RD access doors are combined depending on the circular double-skin duct characteristics and the insulation thicknesses (see RD access doors). Using metal knobs in order to install the IRRD-DW2 access doors on a round ducts having thinner insulation thicknesses as the ones indicated above does not work, as the bolt lengths remain the same.
