Assessments cannot be used to demonstrate compliance with this requirement.

  • Building (Scotland) technical handbook 2019: domestic. 2.7 Spread on external walls. 2.7.1 External wall cladding. Storey height more than 11m – Where the building has a storey at a height of more than 11m above the ground the external wall cladding system should be constructed of products achieving European Classification A1 or A2.

  • Building (Scotland) technical handbook 2019: non-domestic. 2.7 Spread on external walls. 2.7.2 Specified attachments. There is a risk of vertical fire spread from specified attachments to an external wall including balconies, solar panels and solar shading. Solar shading are devices attached to an external wall to reduce heat gain within a building by deflecting sunlight. Fire-fighters may not be able to apply a water jet from a fire-fighting hose directly onto a fire that has spread onto specified attachments high above the ground.

  • Page 14: Note: in most cases, a panel of the tested system wouldn’t contain all the components necessary to function as an external wall (for example, cavity trays, weep holes, etc.). Therefore, any additional components must achieve Class A1or A2-s1, d0.
  • Page 16: Minor components within or passing through an external wall: The aim of the regulation is to remove all combustible components from, or within, an external wall.  The majority of air bricks, weep holes, ventilation ducts, etc. can be produced from materials meeting Class A1 or A2-s1, d0, so products meeting these classifications should be used.
