Attic insulation

Simply more space. We use the right insulation systems to ensure that there is always a good climate under the roof, so you can use your loft as additional living space, for storage or to rent. Whether it’s a separate office space, study, children’s bedroom or a room to rent – there are many reasons to renovate the attic and thus effectively insulate it. With our insulating foams, you not only save energy, but also ensure a stable indoor climate with fewer temperature fluctuations – both in winter and in summer.

Before After
It is important to select the right insulation material. Because with the right materials, moisture and mould growth can also be prevented over the long-term. There are also special requirements with regard to the large temperature fluctuations that occur in the area of the roof.

Foams for every purpose

The benefits of attic insulation with EXY: Honter offers two proven spray foam insulation for loft insulation: EXY 09 spray insulation foam with an open-cell structure and EXY 34 HFO with a closed structure. Both foams are easy and quick to process and impress with their low weight; the strain put on the ceiling construction is insignificant.


With their excellent insulating properties and homogeneous structure right down to the very corners of the roof structure, the foams prevent the formation of thermal bridges and the formation of moisture and mould in the attic.

  • Insulates reliably and effectively - even in hard-to-reach places
  • Reduces heating and air conditioning costs
  • Quick and easy application
  • No mechanical anchoring or wiring necessary
  • No increase in load on the building structure
  • Eliminates heat transfer through the building elements
  • Prevents the penetration of cold air and the formation of thermal bridges
  • Moves the dew point away from the building structure
  • Prevents mould growth and creates a healthy living environment

attic insulation method

The thermal insulation of the attic with EXY insulating spray foam is extremely practical. The foam is applied by spraying and immediately increases its volume many times over. The foam fills even small gaps and joints perfectly and prevents cold air and noise from getting to even hard-to-reach places. No mechanical anchoring of the insulation is necessary because the foam adheres perfectly to all common substrates in the roof area.
No subsequent cutting, no remaining panel sections – just a clean job.

Quick all-round: It’s not just the simple application that saves time. Due to the short drying times of the foam, the hardened mass can be worked on relatively quickly.
