If you want to improve the thermal insulation of your house with a subsequent insulation, you must know and comply with the requirements of the Energy Saving Ordinance.

The EnEV 2014 is aimed primarily at tightening the specifications for new buildings. Thereafter, the insulation of the building envelope in new buildings must be improved by 20 percent, and this provision will not be valid until 2016.

Specifically, the subsequent insulation means that certain limit values ​​must be complied with, with the EnEV 2014 specifying exactly which refurbishment standard must be adhered to for each component. The retrofit obligation applies to top floors that border an unheated attic and that do not meet the requirements of the minimum heat protection according to building standards DIN 4108-2 and 2013-02, whereby the deadline for retrofitting ends at the end of 2015. Alternatively, the homeowner has the option to insulate the roof instead of the attic insulation. The insulation requirement also includes piping, whereby the insulation thickness depends on the inner diameter of the pipes. Hot water pipes and heating pipes in the unheated basement including the fittings must be insulated. The benchmark for the fulfillment of the legal requirements are limit values, which specify the degree of insulation as so-called maximum U-values. With advice and deeds and of course the necessary material you are certainly also the professionals from the specialist market in your area - like building materials Kemmler - to the side.

EnEV 2014 - who is not committed to thermal insulation

Homeowners of a one- or two-family house who lived in their house before 1 February 2002 are not obliged to refurbish the building. However, if you want to carry out renovation work, you have to meet certain requirements, as long as it is an area that is more than ten percent of the component area. However, the requirements are limited only to the area that is to be insulated. For example, if you only want to insulate the northern or western side of a house, you only have to meet the requirements of the EnEV for this area.
