Dublin Airport Terminal 2

Client: Dublin Airport Authority

Location:  Dublin Airport, Co. Dublin

Date:  June 2008 - November 2010

Contract Value: € €62.7 million

Client Representives:  Dublin Airport Authority

MEIC Ltd in conjunction with Martifer Group a subsidiary of the Mota Engil Group were successful in winning the €62.7 million contract for the installation of the Cladding Building Envelope and Glazing of Terminal 2.


Over 50,000m² of straight, curved and tapered convex curved Kalzip aluminium standing seam sheets were installed on Dublin Airport’s impressive new Terminal 2, which became operational on a phased basis in late 2010.

Arup and lead architects Pascall+Watson specified a full acoustic Kalzip system for T2, which was installed by MEIC Ltd in conjunction with Martifer Group.


Project Description:

Dublin airport can be considered a design, test and build project. Martifer has developed over 1000 design drawings. Scaled tests have been performed as between:

  • Acoustic tests for roof and opaque wall;
  • Absorption tests for roof system;
  • Acoustic tests for glazed rooflights;
  • Impact and load tests for glazed rooflights;
  • Air and water penetration tests with 2no 1:1 mock-ups;
  • Site hose tests.


The complexity of the project involves:

  • Roof kalzip system with interface with glazed rooflights being one a spine roof light crossing entire building;
  • Architectural alucobond cladding above substantial area of kalzip roof;
  • Opaque cladding with breather membrane and alucobond;
  • Curtain wall with specific aluminium system design for the project;
  • and all the tertiary steel structure to support above systems.


Note that acoustic and thermal solutions have been specially designed for the project. Solutions adopted are never below 200mm of rockwool insulation and 2 layers of cement particle board.


Relevant quantities:

  • Tertiary steel structure – over 1500 tonnes
  • Main steel structure – over 500 tonnes
  • Kalzip type system – over 30.000m2
  • Rainscreen – over 25.000m2
  • Glazed systems – over 10.000m2
  • Breather membrane – over 5.000m
