How much roof pitch do I need for laying Isola Powertekk? 

Both Isola Powertekk Nordic and Isola Powertekk CC can be layed from 10º roofpitch.

Can I lay Isola Powertekk beneath 10º roof pitch? 

No. Even with additional measures the roof pitch must meet 10º minimum.

Can I use Isola Powertekk with a light weight plank truss? 

Just for these constructions Isola Powertekk – due to its light weight – turns out to be a perfect solution.

What is special with Isola Powertekk? 

The main advantage is its material thickness of 0.5 mm. In terms of stability and laying Isola offers one of the strongest systems on the market available.

Can I walk on a Powertekk roof?
 

As far as the roof pitch allows for walking you can walk inside the great bowls of the plate without problems.

How do you guarantee storm resistance? 

Each single element is fixed multiple with special nails or screws.

Can I use Isola Powertekk for renovation? 

You can use Isola Powertekk with a lot of old roofings without removing it. Though you can save costs for demolition and disposal.

Which kind of roofs don´t need a demolition befor laying Isola Powertekk?
 

All smooth leveled roofs like shingles, slate, fiber-cement ripple and other bituminous roofings.

How about asbestos-containing roofings? 

In this case we recommend to remove the roofing according to the local rules.

Do I have to use a counter batten at all times? 


Yes. In this way occuring condensation can be conducted as quickly as possible.

What dimensions should the counter batten have? 


The minimum ventilation shaft should be 200 cm²/m. The referring size of the counter batten depends on the length of the rafter. Up to 10 m rafter length a 30 mm counter butten is normally sufficient.

Do I have to assemble additional vents at the eaves? 

If the rear ventilation (counter batten) is sufficient and the construction of the eaves is not constricted you don´t need additional vents.

How do I intermediate the distance between the batten if my roof doesn´t fit with the batten spacing? 

You don´t have to adjust the batten space. With a constant batten space of 369 mm for Powertekk Nordic and 371 mm for Powertekk CC you will recieve a smaller rest at the ridge. This tile has to be cut to the righ size later.

Which tools should I use for cutting Isola powertekk? 

The necessary cutting to size should be done "cold" using suitable hand shears or guillotine shears. Cutting can also be done by circular saw with a cutting blade specially for this purpose.

Can I use a normal angle grinder for cutting? 

No. All Powertekk elements should be cut "cold". Heat-generating cutting with rotating machines faster than 4000 rpm must not be used. Overheating of the metal when cutting will damage the corrotion protection (zinc) along the cut edge

I have cut the tiles as recommended. Do I have to seal the cutting edge with the Powertekk repair kit?
But doesn´t that blank steel edge rust?
 

No. Powertekk tiles and all metal accessoires are build cathodic. The close-by primary zinc layers seal the cutting edges with an electro-chemical reaction and protect themselves from rusting.

But how long does that work? 

The cathodic protections guarantees a proper protection over decades.

Are there any guarantees for this fact from Isola? 

Yes, we offer a 30 year warranty concerning corrosion protection.

How long does Isola provide a warranty? 

We provide a 30 year warranty for Powertekk Nordic and a 15 year warranty for Powertekk CC on material.

Can I use a standard window for living rooms? 

Of course. You only need a standard frame for tiles which should be assembled flush to the counter batten.

How can I assemble additional accessoires after the laying of Powertekk? 

Only remove the stormproof fixing. Depending on the size and form of the built-in-part you have to release two rows in the outer field.
