Postup instalace střechy se sklonem od 4 ° do 9,5 °, resp. 15 °
U pergol, garážových stání a běžné pultové střechy nejprve nainstalujte okapové oplechování. Pokračujte horizontální instalací podkladního pásu Armourbase Thermo AD.
Armourbase Thermo AD je samolepivý asfaltový podkladní pás, který se aktivuje teplem. Na spodní straně se nachází ochranná fólie, kterou je nutno před instalací odstranit. Pro rychlost pokládky je lepší, když na pokládce pracují dva. Podkladový pás se nijak mechanicky nekotví (nepřitlouká se hřebíky, ani nepřišroubovává vruty). Přilnavost podkladního pásu začne působením slunce a později, při instalaci šindelů natavením hořákem, se pás zcela přilepí. Horizontální přesahy na podkladním pásu Armourbase Thermo AD jsou 10 cm a koncové/svislé přesahy musí být 15 cm. Po odstranění okrajové fólie na vrchní straně pásu je třeba všechny přesahy přitlačit válečkem.
Nosnou vložkou podkladního asfaltového pásu IKO Armozrbase Thermo AD je velmi odolný a pevný polyester. Pás je současně velmi flexibilní díky modifikovanému asfaltu.

Shingles are applied by torch-on method without nails:
Many special dormers, covered terraces or winter gardens which are connected to the main house have such a low slope that shingles cannot be applied with standard application methods. Usually these slopes are somewhere between 4°- 9,5° degrees.
With the new IKO Shingles Thermo System all types of IKO shingles can be applied over these special low roof parts. The shingles are applied by torch-on method without nails. It means that the roofing layer is not penetrated with holes by roofing nails and that the surface is 100% waterproof. Let’s go over the installation of this Thermo System step by step.
Install the Armourbase Thermo AD horizontally:
Then continue with the Armourbase Thermo AD membrane and the horizontal application on slopes between 4°- 9,5° degrees.
Armourbase Thermo AD is a thermo-adhesive and heat activated waterproofing membrane. On the back side of each roll is a release foil which must be peeled off during the application. To work more efficiently, it’s helpful if two people are involved during the installation. It is not necessary to fix this membrane on overlaps as we did for steeper concrete decks (slope > 15°), because the slope is less than 9,5°.
Horizontal and vertical overlaps of AB Thermo AD membrane:
The adhesion of the underlayment will start partly by the sun, but later-on during the installation of shingles by torch the adhesion will become adequately enough. Horizontal overlaps on Armourbase Thermo AD membrane are 10 cm, but end laps must be 15 cm. When the selvedge foil on top of membrane is removed, all overlaps must be pressed with a suitable roller.
Application of shingles on top of the membrane:
All types of IKO shingles can be used and combined with this method. Start with the precutting of shingles for diagonal application and prepare the starter strip as well. It always helps if you prepare a few shingles before. Get the torch with propane ready and follow all safety rules and regulations when working with an open flame. Very important is to flame only the membrane and not the surface of shingles.
Shingles have to be laid to the melted layer of modified bitumen when the polypropylene mat fabric disappears after torching. The core of the membrane contains polyester which means the underlayment is very durable. At the same time the underlayment is also very flexible because of the modified polymers in the bitumen. Wind-seal dots or self-adhesive parts on shingles will be activated and sealed by the heat of the sun.
Remember: do not make joints and connections between the shingles close to the valley or to any details where a lot of water accumulates! When the shingles are not glued properly on the surface of Armourbase Thermo AD, you can always lift this shingle and flame the membrane again. The membrane is 2,5 mm thick and the head-lap of the shingles will then stick adequately.
