DIN-Taschenbuch 158/1

Thermal insulation, energy efficiency and the thermal performance assessment of buildings are key aspects of building design. DIN Handbook 158/1 brings together the relevant standards for this field and supports standards-compliant planning, calculation, evaluation and execution in the areas of thermal insulation and heating demand.

The 12th edition contains 11 documents in their original text and provides a compact overview of requirements, calculation methods and practical guidance. Topics covered include the fundamentals of heat transfer, thermal insulation and energy efficiency in buildings, thermal bridges, moisture protection, airtightness, and methods for calculating thermal performance characteristics of building components, windows, doors and curtain walling systems. The standards included are current as of May 2026.

The DIN Handbook is structured into the following subject areas:

• Fundamentals of Heat Transfer
• Thermal Insulation and Energy Efficiency in Buildings
• Thermal Bridges, Moisture Protection and Airtightness
• Thermal Calculation of Building Components, Windows, Doors and Closures
• Thermal Performance of Curtain Walling Systems

The documents included cover terms and characteristic values, requirements for thermal and moisture protection in buildings, verification and calculation methods, as well as regulations for assessing the thermal properties of building components and building envelopes. Particular importance is attached to standards relating to thermal bridges, thermal transmittance coefficients, thermal resistance, airtightness and moisture protection.

Compact Practical Guide for Planning and Verification

The collection of standards covers a wide range of topics, from fundamental definitions and requirements to calculation procedures and detailed verification methods. Users are provided with a sound basis for:

• the thermal design of buildings,
• the evaluation of thermal bridges and moisture protection aspects,
• the calculation of U-values, thermal resistance and heat losses,
• the assessment of windows, doors, façades and building junctions,
• the implementation of current normative requirements in the construction sector.

A particular focus is placed on DIN 4108 Supplement 2, which contains planning and construction examples for thermal bridges, guidance on equivalence verification and methods for determining linear thermal transmittance coefficients.

The 12th edition contains the current versions of the relevant standards as of May 2026.

Newly Added Standards:

• DIN 4108 Bbl 2 Ber 1
• DIN EN ISO 6946 Ber 1

Revised Standards:
