Insu­late sus­tain­ably and save energy in the long term.

As a com­pany that deals with the topic of insu­la­tion sys­tems from the ground up with sus­taina­bi­lity and energy saving, we at Münz­in­ger + Frie­ser Hol­ding GmbH pur­sue an envi­ron­men­tally fri­endly and resource-con­­ser­­ving cor­po­rate cul­ture. We have reco­gni­zed that in today’s world it is also important to act in an eco­lo­gi­cally respon­si­ble man­ner and to assume social respon­si­bi­lity.


We are proud to be a company that pursues sustainability as a central corporate strategy and contributes to CO² reduction nationwide with our products.

A cen­tral ele­ment of our sus­taina­bi­lity stra­tegy is the pro­mo­tion of energy-effi­ci­ent tech­no­lo­gies and rene­wa­ble ener­gies in order to mini­mize our energy con­sump­tion and CO2 emis­si­ons. By using LED light­ing, intel­li­gent buil­ding manage­ment sys­tems and effi­ci­ent waste manage­ment, we are actively con­tri­bu­ting to cli­mate pro­tec­tion and have alre­ady hel­ped to improve our car­bon foot­print with various pro­jects. We have alre­ady inves­ted in rene­wa­ble ener­gies such as e‑cars, e‑charging sta­ti­ons and solar sys­tems. We are also com­mit­ted to a sus­tainable sup­ply chain and work to ensure that our busi­ness part­ners also adopt envi­ron­men­tally fri­endly prac­ti­ces. With our 9 loca­ti­ons in Ger­many and 4 loca­ti­ons in Aus­tria, we are also clo­ser to our cus­to­mers and the­r­e­fore have shorter deli­very rou­tes.

Ano­ther important aspect of our sus­taina­bi­lity efforts is social respon­si­bi­lity. We attach great importance to fair working con­di­ti­ons and the pro­mo­tion of diver­sity and equal oppor­tu­ni­ties. We are also com­mit­ted to social pro­jects and cha­ri­ta­ble orga­niza­ti­ons in our region.
