APPLICATIONS WITH POLIISO® TEGOLA DOPPIO PASSO
Microventialted sloped roof below tiles
SIZE
This product is more manageable thanks to the length of 1180mm. Respect of the version of long 2400mm, the product facilitates the mobility, storage and application.

PANELS
The panels with 4 shiplap edges have nominal λD values of 0,022 W/mK according to European standard EN 13165 and compressive strength values of ≥150 kPa; they are 1180 mm long, the width is the double of the step of the tile and the thicknesses range from 60 to 120 mm. The panels have a fire classification of EUROCLASS E according to European standard EN 13501-1; two tile-bearing metal profiles inserted along their length makes them fit for load-bearing. They have holes to favor micro-ventilation under the covering layer.

APPLICATIONS WITH POLIISO® TEGOLA
MICROVENTILATED ROOFS
Poliiso® tegola is a complete system for ventilated sloped roofs and thermal insulation. The product is fit both for the renovation of old buildings and for new buildings. The unique combination of the type of pir foam and coating affords one of the best thermal conductivity λ available on the market (λ = 0.022 w/mk)
A wood or mortar parapet is to be made at the eaves line on the wood or concrete laying surface duly waterproofed with membranes. The purpose of the parapet is to retain the first row of poliiso® tegola panels and it must be just as thick as the thermal insulation layer. Along the eaves line,poliiso® tegola expanded polyurethane panels, without metal profile and with a short pitch (25 cm), are to be laid as the first row of panels.
The joint between the parapet and starting panels is to be sealed with silicone and Poliiso® band butyl tape supplied among the accessories. Continue laying the panels from the eaves to the ridge, from left to right; it is also recommended to arrange the rows in a staggered pattern. In order to reduce product scraps to a minimum, use what remains of the last panel of each row to start the next one. Along the retaining parapet, fasten the supplied vented strip. It serves as a bird screen, support and vent and it provides the right gradient for the first row of tiles. All you need is a cutter to cut or trim the panels; a grinder is needed to cut the metal profiles. POLIISO® TEGOLA is to be fastened mechanically on the underlying structure with nails, self-threading screws or screw anchors, depending on the structure, on the flat rear part of the metal profile.
Seal the short sides of the panels with silicone and waterproofing tape for greater protection against any accidental seepage of rainwater. The panel is treadable, but it is good practice to walk on its metal profile. In order to ensure better ventilation, use a roof vent system along the ridge. Trim the panels of the last row along the ridge depending on the length of the pitch. If necessary, our range of accessories includes a flat single profile that can be fastened to the last panel along the ridge to ensure continuity with the gradient of the covering layer. Along the ridge line and any valleys and hips, use a single-component polyurethane sealant like BOMBOFIX to thermally insulate thermal bridging and then waterproof with POLIISO® BAND aluminum/butyl tape. Once you have finished laying the panels, fasten the tiles to the profile.
In case of a steep roof gradient or in very windy places, we recommend fastening the tiles mechanically. If there are any protruding structures like chimneys, dormers or windows, the continuity in the waterproofing of the tiling layer is to be ensured by sealing the edges around the structures and applying a raised flashing to prevent water from running along the sides and penetrating inside the slab. Lay a retaining strip of at least the same thickness of the panel (60, 80, 100 or 120 mm) along the side of the pitch to fasten the metal flashing. Seal this critical point with poliiso® band. If necessary, in order to lay the flashing correctly, trim part of the metal profile.
ADVANTAGES
- Fast and easy laying.
- Excellent vapor barrier with a µ value = ∞
- Secure support for the covering layer
- Rabbeting on 4 sides to eliminate thermal bridging.
- Excellent thermal insulation thanks to the extremely low value of λD equal to 0,022 W/mK
- Protection against accidental water seepage thanks to the waterproofing with embossed aluminum.
ACCESSORIES
-Poliiso® band, 10-m rolls of aluminum/butyl self-adhesive tape to seal the joints between the panels and waterproof the surface. Available in different widths. -Single metal profiles, 2400-mm long, to ensure continuity when laying the tiles in areas in which the panels are not laid and in the joints in the ridge. -Vented strip with pre-coated metal with l-shaped cross-section of 40x50 mm or c-shaped cross-section with bird screen in p.P. Of 40x110 or 40x60 mm, 1 m in length. The strips to be laid along the eaves line serve as bird screen and ensure the proper support and gradient for the first row of tiles. Ridge vents in aluminum, copper or fabric.
The proper construction of a ventilated roof requires a ridge vent with side bands to be shaped on the adjacent tiles.
- Aluminum brackets to apply the ridge vent.
- Ridge fasteners in pre-coated aluminum.
- Fischer screw anchors to fasten the panels mechanically.
- BOMBOFIX: 750-ml cans of single-component self-expanding polyurethane foam for sealing, fastening and filling.
