D series for massive wood

Firestops to be installed fox example at the wood element factory (e.g. CLT)D series for massive wood structures

D series service penetrations can be used with individual pipes and cables and cable bundles. They are installed in a precisely dimensioned drilled hole. This removes the need for second-stage pouring or other firestop work. The fire classes that are achievable with the products depend on the fed-through building services and the surrounding structure, but the most common fire class for structures made from massive wood materials is around EI 60. The specific fire classes must be checked from the ETA document (15/0411) or from the detail library

With the help of this product the service penetration has very little effect on the structure's soundproofing qualities. The products consist of aluminium cuffs filled with a substance that expands when exposed to heat and a Sewatek feed-through pipe the size of which is determined by the outer diameter of the line pipe. Once the installation is complete, no second-stage work is required except for sealing the root of the line pipe/cable with acrylic caulk. This means the entire service penetration can be installed from start to finish by a HPAC technician, for example. We generally deliver these service penetrations according to the customer's specifications, but if needed, the feed-through pipe between the cuffs can also be shortened on-site.

D42

The D42 is our smallest renovation service penetration and it fits into
a 42 mm hole. The maximum outer diameter of the pipe that is fed through is
approximately 25 mm (28 mm is the absolute maximum, but this is not
recommended). The delivery includes the product and installation flanges that
keep the service penetration in place and ensure a finished look. As with our
other products, the only required work stage after installation is the sealing
of the penetration with acrylic caulk.

D62

The renovation penetration known by the name D62 is the big brother of
the D42. It offers feed-through capacity for pipes and cable bundles up to 43
mm in diameter. The delivery includes the product and installation flanges that
keep the service penetration in place and ensure a finished look. As with our
other products, the only required work stage after installation is the sealing
of the penetration with acrylic caulk.

D92

The D92 renovation penetration is the largest of the three brothers. It
is installed into a 92 mm hole and it can be used to feed through pipes that
are up to 64 mm in outer diameter. The delivery includes the product and installation
flanges that keep the service penetration in place and ensure a finished look.
As with our other products, the only required work stage after installation is
the sealing of the penetration with acrylic caulk.

D105 and D140

The largest service penetrations in the D series differ from the others
in that they are assembled on-site, but this assembly is made very easy and
simple. The D105 requires a 105 mm hole and it enables the feed through of
drainpipes and other pipes up to the diameter of 75 mm. The D140 requires a 140
mm hole and can be used to feed through drainpipes up to 110 mm.
