This document establishes requirements for the installation of embedded radiant heating and cooling systems. It specifies general and uniform requirements for the design and construction of heating and cooling floors, ceiling and wall structures to ensure that the heating/cooling systems are suited to the particular application. The requirements specified by this document are applicable only to the components of the heating/cooling systems and the elements which are part of the heating/cooling surface and which are installed due to the heating/cooling systems. This document is applicable to water-based embedded surface heating and cooling systems in residential, commercial and industrial buildings. The methods apply to systems integrated into the wall, floor or ceiling construction without any open-air gaps, but are not applicable to panel systems with open-air gaps which are not integrated into the building structure.
Abstract
Overview
ISO 11855-5:2021 - Building environment design - Embedded radiant heating and cooling systems - Part 5: Installation - specifies uniform installation requirements for embedded radiant heating and cooling systems. The document applies to water-based embedded surface systems integrated into floors, ceilings and walls (no open-air gap panel systems). It defines installation preconditions and layer composition so that hydronic underfloor heating, embedded ceiling and wall systems perform as intended in residential, commercial and industrial buildings.
Key topics and technical requirements
- Scope and applicability: Focus on water-based embedded radiant systems integrated into the building structure; not for panel systems with open gaps.
- General structural preconditions: Sequence of work - pipework follows electrical/sanitary installations; building openings and wall plaster should be closed before installation.
- Building layers and components: Requirements for supporting base, vapour barriers, peripheral edge strips and interaction with different floor coverings.
- Insulating layers and thermal resistance: Thermal resistance R of insulating layers is calculated per ISO 11855‑3; recommended limits for downward heat loss:
- New construction: limit outward losses to
