Floor conditions may be at a cellar slab on grade with a conditioned cellar or basement. It may also be at the ceiling of the cellar or the floor of the ground level with an unconditioned cellar or basement condition.
Whether Tier 1, 2 or 3 the insulation and airtightness must be continuous.
Horizontal battens over the INTELLO PLUS membrane from a service cavity that may be used to provide additional insulation if desired.
Sheathingless wall framing shows diagonal metal and let-in wood strapping instead of sheathing.
The reinforced SOLITEX MENTO PLUS airtight WRB is installed on the sheathingless framing.
Prior to the installation of the interior air barrier, the sheathingless wall let-in diagonal wood bracing is visible as well as the back side of the SOLITEX MENTO PLUS. (Note diagonal metal strapping is also visible at the roof.)
Black-on-black FRONTA QUATTRO provides heavy-duty weather protection for open joint rainscreen siding. Black TESCON INVIS tape completes the disappearing act. Vertical wood strapping will support the siding.

ProClima Intesana (INTELLO X
predecessor) installedinstalled over the sheathing provides a temporary WRB for the building. The Gutex build-up topped with MULTITHERM rises and will provide the ultimate WRB and outboard wind-tightness.
SOLITEX MENTO 1000 with seams taped with TESCON VANA.
To support vertical siding vertical battens and then horizontal battens are installed.
Diagonal battens over SOLITEX MENTO PLUS with an insect screen applied at the base.
Anything building components that penetrate the control layers need to be fully integrated: windows, doors, skylights, pipes, ducts, wires and more. To the extent that we can limit the penetrations, we ensure a more robust performance of the enclosure. And, for the love of god, do not use spray foam at penetrations - it will crack and fail. Be sure to use flexible materials, combined in flexible ways, such as with a little slack, that can move with the building and don’t become brittle over time.
Working from the bottom up, a sheathingless roof receives SOLITEX MENTO 1000 airtight WRB. The seams are taped with TESCON VANA and battens and cross battens are installed forming a lattice ladder to work from.
Even odd geometries are possible.
Here, SOLITEX MENTO PLUS is taped with TESCON VANA and strapping secured above.
The backside of the SOLITEX MENTO PLUS is visible above, while below strips of INTELLO PLUS have been installed to receive interior stud walls while ensuring simple inboard airtightness continuity.
INTELLO PLUS at the roof structure forms the top of a service cavity filled with ventilation pipes.
INTELLO PLUS at a sloped roof with strapping for a service cavity.
Structural penetrations are taped at the INTELLO PLUS with TESCON VANA. (TESCON PROFIL is recommended due to its split backing.)
Clean wall-roof transition with INTELLO PLUS and furring.
