T-Roof Domo

Preparation:

Installation is done with strips across the direction of the roof slope. Rolling is done from right to left so that the side inside the roll becomes the top side when unrolled. The strips are easiest laid from the bottom and with overlapping subsequent upwards. The substrate should be dry, even, and stable to avoid deflection and movements.

Nailing and seam gluing:

Mechanical fastening for concealed attachment should be corrosion-protected staples type Rapid 140/10 or larger staples with a leg length of 12-15 mm, back width 12.4-15 mm (wire dimension 0.5 x 1.3 mm) or alternatively roofing felt nails min 25 x 2.5 mm. For open fastening in joints, hot-dip galvanized nails should be used!

Infästningen sker dolt i den undre vådens övre klisterkant. Överlappande våd tillpassas, infästs och skyddsfolien på klisterkanterna avlägsnas. Därefter sammanpressas överlappet så att infästningen förblir dold. Alternativt sker infästningen öppen när taklutningen är större eller lika med 14° (1:4). Vid eventuella tvärskarvar används godkänt takpappsklister. För utförligare monteringsinstruktioner och övriga detaljlösningar se separat monteringsanvisning (medföljer varje rulle samt i digitalt

• When covering flat roof tiles, the supplier's guidelines for the underlay must be followed! For unprofiled roof tiles or in wind-exposed areas (near the coast), it is recommended to choose a more secure underlay such as T-Roof Epic.
• The underlay should not be combined with surface layers that are hot air mounted (welded).
• For concealed fastening, carefully check the strength of the joint after installation. Consider adverse weather conditions and ensure any temporary securing of overlaps or protective covering until the permanent surface layer is installed!
• The adhesive edge has aggressive adhesion under normal conditions! In cooler weather (<+10°C), there may sometimes be a need to improve the adhesion. Use a heat gun and gently warm the adhesive surfaces. Press the seam together carefully! In cool weather, rolls should be pre-stored for at least 1 day in a warm storage.
• Be mindful to gently load the surface and immediately repair any damage with roofing felt adhesive Sealant K-36 or equivalent repair compound for bitumen waterproofing. For larger damage, use and attach/glue a strip from the underlay fabric.
• Always cover with the surface layer (tiles, sheet metal, etc.) as soon as possible to avoid exposure to sunlight and adverse weather conditions. During construction, the underlay can be exposed to sunlight for up to a maximum of 3 months. In the usage stage, the underlay should be protected by the outer roof covering.
• Rolls should be stored upright on a flat, dry surface and protected from sun and precipitation.
• T-Roof Domo is diffusion-tight and when mounted on a wooden substrate, the space underneath should be ventilated according to standard practice.
