Trade fair novelties
We presented some new products at DACH+HOLZ.
3D inside corner 90° made of PUR
90° internal corners in the area of the parapet or on the building wall on a flat roof or terrace can be produced easily and without problems using the Grumbach 3D internal corner 90° made of PUR.
Attic corner balcony drain
combines the unique possibilities of a drain in the parapet with the option of routing the drainage pipe to the right or left to the downpipe, close to the edge of the building – for a visually clear line of the external drainage.
Attika corner meso gully made of PUR
Drainage in the corner through the parapet or within the parapet in the inner corner of the building downwards. As with the Attika corner balcony drain, but with increased drainage capacity.
Another Grumbach innovation!
