Flame proof and heat insulation: a must-have.

Cox Geelen's fire-resistant wall plates are heat insulating. When renovating an existing shaft, there is usually limited space available. The installer also hardly has any influence on the materials already present in the shaft; often drawings of the existing situation are not correct or it is hard to see what is in the shaft. In order to be prepared for these types of uncontrollable risks, a fire collar alone is really not sufficient. Cox Geelen's wall plates are flame-proof as well as heat insulating, a must-have for flue gas and chimney renovations!
By installing a fire-resistant wall plate over the opening in the shaft, the flue gas discharge and air supply are restored to at least the same fire resistance requirements as the shaft wall itself.

Fire-resistant wall plates

Cox Geelen introduces round fire-resistant wall plates with integrated fireproof plate and fire protection seal. These innovative CoxDENS® wall plates are available for connection to flexible as well as concentric flue gas systems. These revolutionary wall plates neatly cover an opening in the wall and also provide a fire and carbon monoxide safe situation in the home. Why round? Mounting can not go crooked and the slope of 3° is included in the design.
