Grupo Dema

Grupo Dema develops pipe and fitting systems for water, gas, drainage, and heating. Its brands include Acqua System, Duratop, and Sigas, bringing together components that require application specific selection and coordination with building service routes. Selecting these materials is part of a system-level decision: appearance, dimensions, and application need to be considered alongside the substrate, junctions, and installation conditions shown in the construction details for a proposed building or renovation project.

Specification requires identifying the application, substrate, and product configuration alongside its appearance. Dimensions, joints, attachments, and surface preparation need coordination with construction details; reviewing documentation for the selected line helps distinguish visually similar products intended for different service conditions within a particular building or renovation project.

The catalog provides a reference for studying materials within an architectural project. Final selection can be supported by samples, details, and documentation for the proposed system, linking design decisions with component compatibility, substrate preparation, and the purchasing and installation conditions applicable to the specific construction or renovation work.
