Roof refurbishment from the outside
1. Fill the space between rafters
Completely fill the existing space between the rafters with insulation material. If the existing insulation can be easily compressed, select the next highest thickness for the new insulation layer and use this to compress the existing insulation. Existing and new insulation should only use rock or mineral wool.

2. Roll out and staple the membrane
Install INTELLO X flat over the rafters and insulation, and fasten it using galvanised staples that are at least 10 mm (3/8") wide by 8 mm (5/16") long in the overlap area in a manner that protects against moisture entry. If exposure to the elements is planned, staples installed in open areas of the membrane, at intervals of 10-15 cm (4"-6") along the rafters, should be taped over.
Install the membrane leaving an additional 4 cm (1 5/8") overlap at adjacent building components so that an airtight bond can be applied here subsequently.

3. Overlap the membranes
Allow for an overlap of approx. 10 cm (4") between the membranes and ensure that the upper membrane lies over the lower membrane in the finished overlap to create a waterproof arrangement. The marking that is printed onto the membrane will serve as a guide here.

4. Cut the release films
Cut the release films of the self-adhesive strips in the middle of the roof.

6. Rub the adhesive joint firmly
Rub the seals firmly with the pro clima PRESSFIX application tool to secure them. Ensure that there is sufficient resistance pressure.

7. Joint at bargeboard
Firstly, apply a smooth plaster finish to rough wall caps. Clean the subsurface. Apply a line of ORCON F system adhesive of at least d = 5 mm (3/16") (more in the case of rough subsurfaces, if necessary). Apply the membrane, leaving slack to allow for expansion, and do not press the adhesive completely flat so as to allow for relative motion between components. Alternatively, ORCON MULTIBOND can be used for sealing.

11. Sealing around cables
Place a KAFLEX cable grommet over the cable and stick to the membrane. The cable grommets are self-adhesive.
The range includes:
- KAFLEX mono (see photo)
- KAFLEX duo - for 2 cables
- KAFLEX multi - up to 16 cables
- KAFLEX post - for retrofit installation

The range includes:
- ROFLEX 20 - e.g. for pipes, for Ø 15-30 mm (1/2" - 1 3/16")
- ROFLEX 20 multi - for up to 9 conduits

13. Insulation cover
In the case of refurbishment from the outside and installation between two layers of insulation, the choice of insulation materials for the two layers is limited to mineral or rock wool. Please contact Technical Support at pro clima in Germany for assistance with calculating the possible insulation thicknesses.

14. Install a roofing underlay membrane
The final step is to install a roofing underlay (sd value ≤ 0.10 m; g value ≤ 0.50 MN·s/g; vapour permeance ≥ 32.8 perms), e.g. pro clima SOLITEX MENTO 3000.
