ONDULINE UNDERTILE ® System

Unique roof underlay system utilising corrugated roof sheets for undertile waterproofing

Why ONDULINE UNDERTILE ®?

 

 

ONDULINE UNDERTILE ® is unique roof underlay system utilising corrugated roof sheets below the tile or slate roof covering.

 

An independant secondary weatherproof roof. The primary roof can be used safely below the manifacturer's minimum recommended pitch.

 

For roofs with min. pitch about 10о (about 18%).

 

 

 

 

 

 

Being the most preferred and aesthetically appealing roofing material of the world more than 2 000 years, roof tiles are now available for application through hundred percent watertight, perfectly ventilated and heat insulated systems. The ONDULINE UNDERTILE ® system provides weatherproof layer, ventilation and insulation. It is a unique roof underlaysystem utilising corrugated roof sheets below the tile, slate,or shingle roof covering to create an independant secondary weatherproof roof. This enables the primary roof to be used safely below the manifacturer's minimum recommended pitch.

 

 

ONDULINE UNDERTILE ® is a unique roof underlay system using:

  • special corrugated sheets below all type of tiles
  • full range of components and accessories and
  • technical details for fixing.

SAFE PRODUCT

 

 

ONDULINE UNDERTILE SYSTEM - CONSTRUCTION BENEFITS:

 

Reduced roof pitch 

Allow tiles to be fixed bellow manufacturer’s minimum pitch by providing assured secondary weathering below the primary roof covering.


Immediate weather protection
ONDULINE UNDERTILE
® SYSTEM is quick to install, requires no special equipment or skills, and provides immediate weather protection to the building prior to fixing tiles.


Ventilation

The corrugation of the undertile sheets supply ventilation space above the sheet into the batten cavity, and below into the roof space. This significantly enhances roof ventilation.

 

Moisture protection

With the battens and fixing positioned above moisture flow line in the base of corrugations, excellent moisture control is achieved in the batten cavity.

 

Thermal insulation

The provision of an ONDULINE UNDERTILE ® SYSTEM deck in practice significantly improves the thermal performance of the roof structure.


Sound insulation (27%)

The ONDULINE UNDERTILE ® SYSTEM provides a 27% reduction in sound penetration through the roof covering.


Protection

ONDULINE UNDERTILE ® SYSTEM significantly reduces the risk of expensive consequential damage to the building and interior as a result of damage to the roof through storms or vandalism.

 

 

ONDULINE UNDERTILE SYSTEM - ADVANTAGES FOR DIFFERENT TARGET GROUPS:

 

FOR ARCHITECTS:

 

  • The minimum slope is 15% - lower than normally recommended for tiles.
  • The weight of the roof is reduced.
  • Proper ventilation of the roof structure.
  • Improved thermal and sound insulation of the roof.
  • Clean and straight roof lines.
  • Roofing system – with all details and accessories. 

 

 

FOR ROOFERS:

 

FOR A NEW ROOF

  • The wooden structure is easy to apply.
  • The cost of wooden material is reduced.
  • The productivity is increased - saving labor costs.
  • The installation is easy and the protection is assured even before the tiles are installed.
  • Ready accessories and reliable solutions for the roofing details. 

FOR RENOVATION OF AN OLD ROOF

  • It is not necessary to make full replacement of the wooden structure.
  • Minimal quantity of new wooden material is needed.
  • It is not necessary to uncover entire roof - no need for a temporary waterproofing.
  • It is not necessary to remove the tiles down from the roof - saving labor.
  • Reduced weight of the roof.
  • No need to replace all the tiles.  

FOR RENOVATORS:

 

  • The authentic appearance of the roof is saved - the old tiles can be used, regardless of their condition.
  • Increased reliability of the roof.
  • The old wooden structure can be repaired with less cost.
  • The external wall finishing is not damaged.
  • The under roofing rooms remain clean - dust does not penetrate.
  • The risk of condensation is eliminated.
  • Total cost of the roof renovation is lower.

 

FOR INVESTOR AND END USER:

 

  • Increased security with double coverage.
  • Improved thermal insulation – the energy costs are reduced by about 5%.
  • Improved sound insulation is– the noise from outside is reduced by about 27%.
  • The dust does not penetrate in the attic space.
  • Longer life of the tiles due to the proper ventilation of the roof structure.
  • The roof ventilation is working regardless the humidity of the outside air.
  • Longer life of the under roofing sheet, as is not exposed to UV radiation.
  • Aesthetic roof lines.
  • Economy

Product Range

Several underroofing systems are available according to the tiles selected to cover the roof.
These complete systems provide waterproofing and enable roof ventilation. Ideal for new buildings or for renovation thanks to their lightweight, they keep the aesthetics of the existing roofing.

 

System ISOLINE ®

 

ISOLINE ® is a special waterproofing sheet applied under the roof tiling. It is compatible with all type roof tiles. An air space resides beneath the Isoline gutter. This space helps to discharge the vapor inside the building before it condenses, creating an air circulation over the heat insulation materials.
Additionally, the flow of air created among the roof tiles and Isoline allows rapid drying of roof tiles. Roof tiles are laid into the special battens fixed to the Isoline sheet. An aesthetically appealing look is thereby obtained with easy and fast workmanship. The ISOLINE ® system’s applications is very easy and compared with full desk roofing systems this application technique availed by the highly strong structure of Isoline provides up to 70% saving from wood battens used for roof covering, while ensuring a significant reduction in the overall cost of roofing.
  

System RUFOLINE ®

 

RUFOLINE ® is a perfectly compliant with round (roman) tiles with medium length. The ventilation, which is of core consideration also for traditional roof tiling, is best provided with RUFOLINE ® undertile sheets , possessing an under-gutter spacing. 
A good ventilated roof is ideally beneficial even under very hot air conditions, for heat insulation aspects. RUFOLINE ® supports the roof tiles with a special profile especially for round (roman) tiles application. It is possible to fix the tiles of the covering system. RUFOLINE ® is an under-roofing waterproofing material that can be applied on battens laid with interspaces. Providing more than 70% of savings in the costs of covering wood, this type of application minimizes the overlapping losses inherent with round (roman) tiles.
