Advantages Of Aluminum Foil With Bitumen For Roof Insulation
Nov 22,2022

If compared to other conventional vapour barriers, 8011 aluminum foil has some properties which generally (and also in some cases) have an advantageous effect in combination with the bitumen sealant.For purposes of insulation aluminum foil is characterized by the following properties:

1. heat resistant

2. impermeable
3. non-flammable
4. light
5. ageing resistant
6. UV-stable

Through self passivation, aluminum foil also offers corrosion protection. However, in the case of external applications with contact with rain or in the nearby area of seas with salt water, 8011 aluminum foil should be varnished or protected in a different way.

Aluminum with bitumen for flat roof insulation. Although aluminum counts as a tough metal, an aluminum foil can for sure be pierced or torn by pointed and sharp edged objects. This is due to its low material thickness, which can be in the range between a few micrometers and millimeters Especially when it is placed on a soft surface, like for example on an insulating materialIn context of building insulation, such risks exist above all in the processing and in accesible roofs that are flat. This problem disappears, if the aluminum foil is combined with bitumen to a composite material in a similar way to aluminum composite plates.The bitumen on flat roofs protects the 8011 aluminum foil from damage.

Aluminum foil with bitumen for industrial roof constructions. The building insulation of roofs in the field of industry must fulfull certain special requirements, especially with regard to fire protection.Bitumen roof sheets with support of 8011 aluminum foil also meet these requirements. They meet the requirements of DIN 18 234 for fire protection for large-area roofs. Those are often found in the industry. In the case of fires in the interior of the building, such aluminum bitumen roof sheets do not have a fire-retardant effect.Aluminum roof sheets are suitable for conventional roof constructions with insulation underneath of the vapor barrier, and as well for inverted roofs, where insulation materials lie above. Here in this type of construction, it is advantageous with industry roofs that the waterproofing with bitumen and aluminum foil is applied as a first layer during the construction of the roof structure. It can then serve as an emergency seal until the actual insulation material and the support have been applied and used up.While sealing sheets with aluminum foil in form of welding strips require a full-surface support, there is special self-adhesive variants that are also suitable for application to trapezoidal sheets. Self-adhesive bitumen sheets with 8011 aluminum foil are also very suitable for sealing vertical building parts.
