Doerken combines insulation and renovation

NEW PRODUCT for renovation: DELTA®-MAXX COMFORT
Highly vapor permeable insulating under-roof system

Effective insulation of pitched roofs is essential for comfort and well-being in the attic. Roof renovation, generally carried out by
the exterior, is subject to constructive, hygrothermal and cost constraints which limit the range of technical solutions that can be envisaged.
DELTA®-MAXX COMFORT is ideal for renovations because it improves the energy balance without fundamentally transforming the structure and without raising the roof.

The DELTA®-MAXX COMFORT screen...
...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.

Les avantages en bref :

• 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
• implementation directly in contact with the thermal insulation between rafters (HPV screen - R3)
• windproof thanks to the integrated self-adhesive strip
• 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
• as rain protection in timber-framed constructions.

Technical characteristics

• Sd value (excluding geotextile): approx. 0,08 m
