Energy-saving 4-layer vapor barrier film DELTA®-REFLEX with a heat-reflective coating for pitched and flat roofs.
The feature of the Delta Reflex/Delta Reflex Plus vapor barrier film is the presence of a special reflective aluminum layer. This structure provides strength, reliability of the roof structure, preventing the penetration of moist and warm air. The vapor permeability of the material tends to zero.
DELTA®-REFLEX film description
DELTA®-REFLEX provides 100% reliability against the penetration of water vapor into the building structure due to almost zero vapor permeability (Sd> 150 m). It has a record strength of 450 N / 5 cm and at the same time high plasticity, even at low temperatures.
Hermetic gluing of overlaps and junctions guarantees protection of the roof from convective transfer of water vapor contained in the warm air of the attic.
DELTA®-REFLEX re-reflects up to 50% of the heat energy inside the room thanks to the reflective layer, which reduces your heating costs in winter. The sprayed aluminum coating is protected on the outside by a transparent polyester film. This guarantees the protection of the functional heat-reflecting layer from corrosion during wet finishing work in the building.
Using DELTA®-REFLEX film
The combination of high strength and plasticity allows you to mount the DELTA®-film REFLEX over large areas without the risk of damage due to excessive tension. The film easily holds the load from the insulation. It is recommended for the installation of a vapor barrier layer in houses with permanent residence. It can be used in wet areas (pools, bathrooms, kitchens) of residential buildings and industrial buildings.
It is used on pitched and flat roofs, as well as in the walls / ceilings of frame structures. DELTA®-REFLEX overlaps are glued with DELTA®-MULTI BAND or DELTA®-INSIDE BAND single-sided tapes. Before gluing, it is necessary to wipe the overlap area to remove dust, this is a mandatory requirement in a dusty construction site. When using chemical additives in plaster or floor screed, you should first check the compatibility of additives and their vapors with the film in order to prevent damage (corrosion) of the aluminum layer. We recommend that you always seal with DELTA®-MULTI BAND or DELTA®-INSIDE BAND tapes the fixing points of the film with staples.
The film meets all the requirements of the new STO of the National Roofing Union 2.1-2014 "Vapour Control Layer" and the Code of Regulations of the German Union Roofers (Fachregeln des ZVDH).
