Daco-KSO Self-Adhesive Cap Sheet

Application

Designed for use as a premium cap sheet (top layer) and suitable for use within cold-applied roofing systems.

The product is typically used within TECHNONICOL’s self-adhesive or torch-safe specifications and is compatible with DACO-KSU+ self-adhesive underlay membrane.

Description

A cold-applied, self-adhesive bituminous cap sheet which is saturated and coated with high quality SBS (Styrene-Butadiene-Styrene) modified bitumen.

It has a strong 280 g/m² polyester/ glass composite reinforcement and features integrated ‘safe-seal’ lap technology, facilitating secure, safe and efficient sealing of side-laps.

The upper layer of the membrane is protected with slate mineral and the bottom layer is coated with self-adhesive compound, covered with removable film.

In addition, DACO-KSO+ incorporates a special graphite additive within the coating to provide exceptional fire protection properties, and has been fully fire tested as part of a designated system in accordance with EN 13501-5 and DD CEN/TS 1187:2012, Broof Test 4.


Features and benefits:

  • Flame free, self-adhesive application.
  • Excellent low temperature flexibility at -25°C.
  • 280 g/m² polyester/ glass composite reinforcement.
  • SBS modified bitumen.
  • Incorporates Börner graphite technology which actively prevents spread of flames on the roof.
  • Tested as part of a system to achieve Broof Test 4 fire classification as certified by Warringtonfire.
  • Integrated ‘Safe-Seal’ laps to enable homogenous, efficient sealing of side laps.
  • CE marked.


Technical characteristics:

  • Straightness (to DIN EN 1848-1): <20 mm/10m.
  • Resistance to thermal distortion (to DIN EN 1110): +100°C.
