The entire roof deck should be covered with IKO Armourbase underlay or an approved shingle underlay.

The underlay should be installed parallel to the eaves with a min. 10 cm horizontal lap and 15 cm end laps.

On all IKO Armourbase underlayments there are 10 cm lines on the rolls for easier overlapping.

Secure the underlay with only enough nails to hold it in place.

Other features are: 

  • the little bulk of each roll allows operator to carry more rolls during handlings and transports
  • despite its lightness it shows good waterproofing properties (it is W1 ranked and has average values of 4 m in the water column test): thanks to the particular bituminous compound able to enhance its waterproofing behaviour
  • it has a very valuable resistance to cold (up to - 45 °C!!!) allows it to resist also in extreme cold weather conditions
  • the total adhesion on the continuous support protect it from external atmospheric agents
  • application lines on the surface make the application more easy and precise
