DANOPREN TR

INVERTED ROOF

• The roof structure load-bearing capacity will be checked.
  
• Before installing DANOPREN TR XPS boards it is recommended to run a leakage test.
  
• DANOPREN TR XPS boards are part of a waterproofing system, therefore the systems and indications reflected in the Danosa solutions
  

technical manual, product/systems specifications and other technical documentation should be taken into account.

• A suitable separation layer (for instance a fabric like DANOFELT PY 150) shall be installed between the DANOPREN TR XPS boards and the waterproofing membrane, especially in case where it might arise any chemical incompatibility, such as in the case of PVC membranes (in this case, a fabric like DANOFELT PY 300).
  
• DANOPREN TR XPS boards shall be installed loose-laid. Otherwise, a justification why not must be provided.
  
• DANOPREN TR XPS boards shall be installed with staggered joints between successive rows.- DANOPREN TR XPS boards shall be installed with all their joints tight.- When close to every detailing, the DANOPREN TR XPS boards will form the joint with at least a 5 mm tolerance.
  
• A suitable separation layer (for instance a fabric like DANOFELT PY 200) shall be installed between the DANOPREN TR XPS boards and the ballast (gravel or paving).
• A suitable ballast in conditions, weight and distribution will be immediately installed, in order to avoid possible wind uplift. For a non-accessible roof, gravel ballast (rounded low fines of nominal size 16 mm to 32 mm) should be washed and laid to a minimum thickness of 50 mm.
  
• It shall be avoided any ballast that may form a tight vapor diffusion layer on top of the DANOPREN TR XPS boards.
  
• When close to every detailing, the DANOPREN TR XPS boards will form the joint with at least a 5 mm tolerance.

RESIDENTIAL AND COMMERCIAL FLOORS

• The structural deck must show proper leveling and flatness (checked with a 2 m rule level). Otherwise it may be necessary to form a sand layer for proper leveling. This sand layer may also allow for horizontal pipes installation. If the structural deck shows proper leveling, the sand layer may go above the insulation boards. In this case it can incorporate a heating floor system.
  
• DANOPREN TR XPS boards must be installed loose-laid, with tight and staggered joints between successive rows.
  
• In the case of slab insulation, DANOPREN TR boards may be placed directly onto the ground, once the soil is properly compacted. Then the boards can be placed, as indicated in the previous bullets. If a plastic film is installed as a watertight barrier, it is recommended to place it above the DANOPREN TR boards, i.e., by their “warm” side.
  
• A screed of at least 40 mm thickness will be installed, as a bed layer for the pavement, above the DANOPREN TR boards. For light or adhered flooring finishings, a minimum 30 mm screed is recommended, reinforced at least with a 220 g/m² mesh.
  
• In the case of heating floor systems, the DANOPREN TR boards must be placed below the heating system. Thus the “heat theft” between homes with heated flooring systems is avoided. The floor heating will form joints -for example, with DANOPREN CH shavings- in all junctions with walls and partitions.
