Limit energy loss with Doerken Delta Maxx Comfort

Exterior roof renovation and improvement of the energy balance

Conventional roofs are often responsible for 21 to 30% of the significant energy losses in older homes. Roof renovation is therefore essential to improve home insulation.

The Delta®-MAXX COMFORT, designed specifically for the renovation of sloping roofs

...is a highly vapor-permeable insulating under-roof screen that allows thermal insulation between rafters to be supplemented from the outside.

...is waterproof, windproof and highly permeable to water vapor: it combines the advantages of an HPV under-roof screen and thermal insulation.

The advantages in brief

improvement of the thermal performance of the insulated sloping roof by up to 25%

significant reduction in losses through thermal bridges which can lead to mold

significantly increases the wind tightness of the house thanks to the integrated self-adhesive strip

implementation directly in contact with the thermal insulation between rafters (HPV screen - R3)

limited roof elevation, ideal for renovating existing roofs

installation similar to that of a traditional HPV under-roof screen

Areas of use

in the renovation of sloping roofs to improve the energy balance (9% energy saving)
