DANOPREN TL
Rigid extruded polystyrene (XPS) foam board for thermal insulation of pitched roofs.
Product variations:



DANOPREN TL is a rigid extruded polystyrene (XPS) foam board with a grooved surface finish on one side with shiplap edges. Comes at various thicknesses. Manufactured without CFC's, HCFC's or HFC's.
Instruction for Use
SLOPING ROOF
- The condition of the load-bearing substrate shall be checked to ensure that it is suitable for the various loads and overloads of the roof system.
- In case of a safety waterproofing on the load-bearing substrate, e.g. with double-sided self-adhesive sheets, the installation instructions for these products shall be followed. Maximum slopes in this case: 30 degrees (= 57%).
- The DANOPREN TL XPS insulation boards are installed on the substrate with the grooves parallel to the ridge in order to give the best possible anchorage to the mortar used to bond the tiles. The tiles are thus installed on the DANOPREN TL sheets in the traditional way, by a mortar bead, without the need to install an entire compression layer between the insulating sheets and the tiles.
- DANOPREN TL boards shall be mechanically fixed or bonded with a suitable adhesive to the substrate. Minimum fixing pattern: 4 fixings per board on the perimeter of the skirt and joints (e.g. chimneys); 2 fixings per board on the rest of the skirt. If adhesives are used, a similar distribution shall be maintained. Maximum slopes in this case: 45 degrees (= 100%). In any case, for each type of tile (curved, mixed, flat) the appropriate slope range shall be respected, according to the usual construction practice.
- A cavity shall be formed to cover the insulating sheets at gable ends and, above all, at the eaves, in order to retain them in case of possible movement or slippage.
- If the topographical situation is very exposed to wind, a special study is recommended to determine the best fixing system. In this case, however, the tile is always installed with mechanical fasteners (hooks, nails, etc.) and it is then necessary to interpose a screed, either fixed to the structural support by means of the DANOPREN TL sheets, or received with mortar to the sheets themselves.
