IKO Shingles Thermo System

The concept consists of

a primer for the roof deck and
a thermo-adhesive and heat activated waterproofing membrane,
where all residential IKO shingles can be adhered to the membrane (no nailing required!)

IKO Armourbase Thermo AD is an aesthetical solution for low sloped roofs in:

OSB (min. 4° - max. 15°)
or concrete (min. 4° - max. 45°)

with a secure concept system, finished with IKO shingles.

Application and general Thermo AD concept information

Ideal solution for…

Low slope wooden deck: Slopes between min. 4° and max. 15° need to be applied horizontally without the Armourbase Thermo AD being affixed mechanically on overlapsbeing affixed mechanically on overlaps.
Concrete deck: Horizontal application without mechanical fixing on slopes between min. 4° and max. 15°. For steeper slopes (max. 45°), vertical application with mechanical fixing of the membrane with screws (+ metal plate) on the overlaps is mandatory.
Thermal insulation on concrete / OSB shingle roof (min. 4°- max. 15°): The thermal insulation must be applied and mechanicaly fixed on the concrete deck or on the OSB deck only for slopes between 4° and 15°. In these cases Armourbase Thermo AD must also be fixed on overlaps because of the underlayment’s adherence to insulating elements.
Renovation existing flat roofs (> 4°): (only if the roof is dry, clean and watertight) Primer AD + mechanical fixation needed to install this concept.

How to apply the torch on system?

Application of the underlayment on a wooden deck

Apply the membrane parallel with the eaves - vertical and horizontal overlaps should be min. 10 cm. Set the roll of Armourbase Thermo AD and remove the release film from the back. In warm, sunny weather the underlayment will stick with the wooden deck in a short time.

For slopes between 4° - 15° it is not necessary to fix the underlayment on overlaps. It is advisable to go with proper metal flashings at the eaves and rakes.

Provide horizontal and vertical overlaps 10 cm between the sheets and make sure to remove the side selvedge release foil. After application use a suitable roller and apply pressure over all overlaps.

The adhesion of Armourbase Thermo AD will start with the application of bituminous shingles by torch-on.

Application of the underlayment on a concrete deck

Apply the membrane parallel with the eaves - vertical and horizontal overlaps should be min. 10 cm. The position of Armourbase Thermo AD on the concrete deck with slopes higher than 15° should be perpendicular to the eaves.

The concrete deck must be primed with the Primer AD (bituminous primer) before the application. Set the roll of Armourbase Thermo AD and remove the release film from the back. In warm, sunny weather the underlayment will stick with the primed concrete deck in a short time. In cold weather you can help to set the Armourbase Thermo AD underlayment with a hot air gun or a torch.

For slopes between 4° - 15° it is not necessary to fix the underlayment on overlaps. For concrete decks with slopes between 15° - 45°, fixation is mandatory. This can be ensured with screws and metal pressure plates for concrete. There is a need to pre-drill holes every 30 cm on overlaps. It is advisable to go with proper metal flashings at the eaves and rakes. Provide horizontal and vertical overlaps 10 cm between the sheets and make sure to remove the side selvedge release foil. After application use a suitable roller and apply pressure over all overlaps.

The adhesion of Armourbase Thermo AD will start with the application of bituminous shingles by torch-on.

Application of bituminous roof shingles on wooden and concrete deck

This shingle application is similar to the regular shingle application concept which starts with a starter strip (a shingle with tabs cut off). Apply by heating/flaming the top layer of Armourbase Thermo AD until the polypropylene mat fabric disappears and the top bitumen coating is melted.

Lay the shingle to the melted top adhesive layer of the membrane in its proper place. If necessary, lift the upper part of the shingle with a trowel. Heat up the section of the membrane just underneath the lifted shingle. The back of the shingle should be warmed in order to get the best possible adhesion.

Continue with the diagonal installation of shingles, without using nails. It’s not necessary to torch the shingles from the top. Excessive heat can damage shingles. Essentially shingles are applied for aesthetic reasons only and the waterproofing properties derived from the roofing membrane. For the torch-on method and slopes up to 45° the fixation of shingles with nails is not necessary.

The Armourbase Thermo AD membrane will bring about the total, monolithic adherence between the support and the bituminous shingles.

Torch only on the upper face of the membrane and stick the shingles in the activated Armourbase Thermo AD. Do not torch the shingles!

Hips and ridges on a wooden deck

With hip and ridges, the underlayment is already covered with shingles. Therefore hips and ridges are installed by gluing the parts. For the hip or ridge, the Armourvent Multi ventilation can be applied from a 4° slope.

Armourvent Multi must be glued on both sides with the IKO Shingle Stick and then nailed to the wooden deck. Hereafter the shingle capping will be applied over it the same way as with a roof > 15°.

In special cases, when the insulation is between the wooden deck and shingles (the warm roof) and the pitch of this roof is between 4° - 15°, the mechanical fixing is mandatory.
Then the best and most recommended solution will be to torch APP shingles over this structure.

Hips and ridges on wooden deck with Thermo AD membrane

For slopes between 4° and 15°, IKO recommends installing an extra OSB or wooden wedge and raising the ridge with Armourvent Multi ventilation. This avoids water infiltration in case of ponding water close to this ridge.

Hips and ridges on a concrete deck

On a concrete deck, a piece of 30 cm is trimmed from Armourbase Thermo AD and torched on the top part of the roof over the last rows of shingles. Then the capping can be torched over this membrane. Given the density and thermal mass of concrete decking, ventilation is not required in the air space beneath the deck.
