The Term "Neuholz" may be refer to "Neu Holz LLC" in Dubai or not. Anyway, the only produce MDF 'Coated with melamine veneer', HPL (High Pressure Laminate) and High Gloss MDF for flooring, not for ceilings acc. their homepage.

'Neuholz' is also a name for 5 locations in Swizzerland, and that what the word means in order to distinguish it from 'Altholz'.

'Katzendecke' may be an OCR error or a typing error. On QWERTY keyboards you will find "Z" on the lower key bank just below the "S". On QWERTZ you will find the "Z" right of the "T". And other keyboards have different key orders, too. So, I will start from this assumption and look for appropriate terms:

Kassettendecke f (Arch) cassette ceiling, caisson ceiling, coffered ceiling, pan ceiling, panelled ceiling, rectangular grid ceiling, waffle ceiling

:
Eine Kassettendecke (auch Felderdecke) weist an ihrer Unterseite in regelmäßiger Anordnung kastenförmige Vertiefungen (Kassetten) auf. Eine solche Decke wird durch sich kreuzende Rippen oder Balken gebildet. …
Kassettendecken entstanden ursprünglich dadurch, dass die eher dünne und flächige Füllung der Felder auf der Oberseite der dicken, hohen Balken aufgebracht wurde. Eine hängende Befestigung war schwieriger, außerdem brachten die Vertiefungen technische Vorteile (Akustik) und eine optische Gliederung der Decke.

A coffer (or coffering) in architecture is a series of sunken panels in the shape of a square, rectangle, or octagon in a ceiling, soffit or vault.[1] A series of these sunken panels was often used as decoration for a ceiling or a vault, also called caissons ("boxes"), or lacunaria ("spaces, openings"),[2] so that a coffered ceiling can be called a lacunar ceiling: the strength of the structure is in the framework of the coffers.

The coffered ceiling is a common motif in architecture that dates back to ancient Greek and Roman times. These ceilings were used for large public buildings, where they needed to create indentations to distribute structural weight, lighten the load of high ceilings and bring symmetry to a high ceiling.
:
Waffle ceilings are a type of coffered ceiling. These two ceiling designs are often used interchangeably but are very different in their design, function, and installation process. Waffle ceilings have beams that cross rectangular panels to form a waffle pattern, hence the name.

Conclusion: I would maintain the term 'Neuholz' as this either a name referring to new wood or any town. The term 'Katzendecke’ is most probably an misprint for "Kassettendecke" i.e. 'coffer', but I will not exclude other meanings as a pictured cat.
