Couvernet®

Couvernet® is an aluminium coping system which prevents water infiltration, whether the walls are sealed or not. These coping have invisible fixtures allowing free expansion. This type of cover protects parapet walls, insulation, water-tightness of the roof, as well as the roof's façade. Couvernet is also compatible with Barrial balcony railings/balustrades. 

System components


This kind of "top-hat" protects the parapets (1), insulations (2), roof-terrace waterproofness (3), as well as the outer walls covering (4). In order to ensure the waterproofness and the perfect finish of the system, all the components are tailored-made in our workshops, in accordance with measurements taken on the construction site by the installation company. This customized approach allows dani alu to cater to all requests, from the easiest to the most complexed.

Couvernet® EWIS

couvernet-couvertine-aluminium-protection-infiltration-etanche-toiture-coiffe-facades-couvertines-acrotere-murets

Couvernet® EWIS


Couvernet® EWIS is an aluminium coping system for parapets with external wall insulation system (EWIS). According to professional recommendation n°4 of the CSFE and RAGE, parapets with height lower than 600 mm must be protected and insulated, which is provided by Couvernet® EWIS.
 
Specific supports allow a reduction in thermal bridges generated by the fixing of a coping on the insulated parapets.

There are two types of supports :
  • support EWIS with console Th 
  • support EWIS with plate Th

These supports can be combined with coping with a width of 600 mm max (for other dimensions, please contact us).

 


Couvernet® support EWIS with console Th allows :


Creation of coping on width and downstands.
An adjustment of the height and the slope of the coping on the construction site. 
Adaptable to any kind of insulation
Reduces the thermal bridge
The console Th is adjustable in height (30 mm), slope (-10°) and translation (+/- 7 mm). It reduces the thermal bridge by 22.5% by integrating a thermal bridge breaker.* 
(*Thermal bridge : 0,24 W/mK for a concrete parapet of 200 mm wide, 325 mm high, R courant et R facade = 5 m. K/W, Rparapet = 4 m. K/W)

Field of application :


This system is also adaptable without insulation (façade cladding).

System components


  1. Rounded edged coping 
  2. Slider 
  3. Console 
  4. Thermal bridge breaker 
  5. Insulation 
  6. Rainwater collector 
  7. Joint cover strip : 
    • improves junction weatherproofing 
    • covers inaccurate cutting

  3. Fixing (mechanical anchors M8 not provided) 
  4. Structure
  5. Insulation brought to waterproofing on parapet's head 
  6. Joint cover strip
 

Couvernet® EWIS support with plate Th allows :


  • Creation of coping on width and downstands 
  • Reduces the thermal bridge

The plate allows a relief in the tightening pressure without damaging the insulation. 
It has a 2° slope which facilitates the rainwater to flow towards the inside of the parapet. 
-45% of thermal bridge* compared to a traditional solution 
(*Thermal bridge : 0,17 W/mK for a concrete parapet of 200 mm wide, 325 mm high, Rcourant et Rfacade = 5 m. K/W, Rparapet = 4 m. K/W)
