HOW DOES ISOLINE UNDER-ROOFING SYSTEM WORK?

Large waterproofing sheets are laid under the primary roofing, creating an effective roof under your roof. The roofing underlays system repels any water that might seep through the damaged primary roof. Installation is extremely fast, and the interior of your house will remain dry throughout the work.

Unmatched waterproofing for pitched roof

ISOLINE sheets provide a fully waterproof layer to resist all weather conditions. Reliability has been proven in the world’s most extreme climatic conditions for more than 80 years. Allows owners and occupants to feel safe in their homes. Empowers roofing professionals to focus on the next job instead of wasting time fixing old sites

A solution against leak that fits any tile

No matter the type of primary roof you wish to use, the ​ISOLINE roofing underlays ​will fit! It can be used with any type of clay or cement tiled roof or metal or UPVC sheets, it will fit any roof, regardless of shape or pitch. 
 

Minimum Roof Pitch

The use of many roof tiles and roofing sheets are limited to a minimum pitch.  If used on roofs below this level, the roofing tile’s waterproofing  performance is compromised.  With ISOLINE UNDER ROOFING, roofing tiles and roofing sheets can be fixed below the manufacturer’s recommended minimum pitch.  ISOLINE delivers full waterproofing at pitches as low as 10°
➔Any tile can be used (even trendiest flat ones)
➔Living space is increased

Dual ventilation

ISOLINE sheets allow air to circulate above and below corrugations, providing excellent ventilation. Air circulating beneath the sheets helps to discharge vapor before it condenses. Flow of air between the sheets and tiles allows the roof to dry rapidly

Preserves the original style of historical buildings

If the original tiles are high-quality and well-preserved, they may be able to be reused on top of your new ISOLINE roofing underlays , maintaining the original historic aesthetic. ​In that case, Onduline roofing underlay will act as the primary waterproofing material, while the tiles protect the building. 
Reusing original tiles also means ​significant savings in your renovation budget​.
