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 

Example of application

Couvernet^® EWIS with console Th, asymmetrical rounded edges

1. Couvernet^® asymmetrical rounded edges
2. Support EWIS with console Th (for any kind of insulation) 
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)

Field of application :

Insulation of C class minumum (rigid insulation).

System component :

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

 

Example of application

Couvernet^® EWIS with plate Th, asymmetrical rounded edges 
Dimensions are to be taken into account. The coping inside downstand covers 40 mm of the sealing.
The coping external downstand covers :

• 50 mm if the height of the building is lower than 28 m
• 100 mm if the height of the building is higher than 28 m or if the building is on the seafront.
