For Trespa, sustainability is about creating lasting products that people do not want to replace. 
Why don’t you sell an installation bar?

What type of ventilation should I use?
We would recommend the 2.5m ventilation profiles provided through our accessories range. They are available in Rigid Black PVC and Black Aluminium via our shop.
 
What is the width of the ventilation profile?
There are two types of ventilation profiles, Rigid Black PVC and Black Aluminium.

The Rigid Black PVC has a width of 100mm that can be trimmed to size.

The Black Aluminium is a standard 50mm.

The ventilation profile used depends upon the size of the cavity between the wall and the planks.

When you double batten for vertical installations, it is recommended you use the Rigid Black PVC profile for the required width.
 
Can you explain the Pura® NFC fixing system?

Pura® NFC sidings are fixed onto a wooden or aluminium subframe with clips. More information can be found at trespa.info.

How many clips do I need per square meter to install a Pura® NFC façade?

For a 600mm centre installation, 12 - 15 fixing items (clip + screw) per square meter would be estimated. However, for rigidity, central distances should be determined in accordance with local regulations & location requirements i.e. coastal / hilltop. As well as the applicable engineering requirements for each particular building, where more clips maybe required.

How do you seal off battens so you can’t see the clips?
Ventilation profiles are used to seal off the bottom section of the cladding. They also prevent rodents and leaves from entering the ventilation gap between the cladding and the wall.
 
What is the minimum cavity behind the back of the Pura® NFC fixing system?

Minimum cavity needs to be 20mm.

What is the minimum air gap top and bottom of the Pura® NFC fixing system?

Minimum air gap is 5mm.

How close is the clip fixed to the end of the plank?

20mm up to a maximum of 80mm.

What is the positioning tool used for?
The positioning (spacer) tool included with the universal clips is provided to allow 1mm vertical expansion between the clip and Pura® NFC edge.

Where can I use outer-corner profiles?
Outer-corner profiles, as the name suggests, can be used in the outer-corners of your installation. The corners can also be used around windows and doors to create a neat finish.
Where should I use finish profiles?
Finish profiles can be used anywhere you feel they will enhance your installation. Our customers have used them in corners where the space is not configured in such a way that it would fit an outer-corner profile – for example, above window frames and around doors, to name a few.
 
Are corner and finish profiles necessary?
Neither profile is necessary when installing Pura® cladding however, they can provide an aesthetically pleasing finish to your design.
 
Is the support profile only for vertical installations?
In theory, yes the support profile should be used to start the vertical installation of Pura® cladding but, as with the other profiles available, they may be used in horizontal applications by installers if desired.
 
Can I fix the cladding directly onto plywood?
No, Pura must be installed onto battens, with a cavity of at least 20mm deep behind the cladding to ensure natural ventilation.
