Installation Guide
Mounting instructions applicable to all DUCO glass-mounted window ventilators except FireMax & SkyMax
Contents
Dry glazing
- Take the glass for the provided window ventilator
- Select the rubber gasket with the right width and height
GGC(21)22-30
GLAS (15)16-24
GG(31)32-40
GLAS (25)26-34
GG(41)42-50
GLAS (35)36-44
GG(51)52-62
GLAS (45)46-56 - Cut the rubber gasket to the correct length. Length of glazing gasket = total ventilator size-(2x rebate). E.g. rebate 40mm
gasket = total size ventilator-80mm
- Place the gasket centrally on the glass.
- Take the window ventilator and check that a joint sealing tape is glued into the rebate on both sides
joint sealing tape: 25/4-8
Type: Open cell polyurethane foam tape, impregnated with a polymer dispersion with fire-retardant additives
The joint sealing tape must fit nicely on the side of the end piece or rebate black This joint sealing tape must overlap the gasket on both sides by at least 20mm! E. g. rebate = 40mm joint sealing tape must be at least 40mm long
If the joint sealing tape is narrower than the glazing channel, it should be applied on the outside of the window ventilator - Break off the tabs at the bottom of the end pieces
- Lay a continuous silicone seal 1 cm from the sides of the glazing gasket
- Place the window ventilator over the rubber gasket on the glass and press firmly.
- Place the glass with the window ventilator in the window.
- Attach the glazing bars and sealing rubbers to the window.
When mounting, take care that the window ventilator fits tightly to the glass.
In doing so, the distance between the window ventilator and the glass with rubber should not exceed 3mm to ensure proper functioning of the joint sealing tape.
For rebate 25 mm with filler blocks:
The filler blocks must always be completely behind the glazing bar. The glazing bars must clamp onto the fixed part of the end piece!
Wet glazing
- Take the glass for the provided window ventilator
- Take the window ventilator and check that a joint sealing tape is glued into the rebate on both sides.
joint sealing tape: 25/4-8
Type: Open cell polyurethane foam tape, impregnated with a polymer dispersion with fire-retardant additives.
The joint sealing tape must fit nicely on the side of the end piece or rebate block. This joint sealing tape must overlap the gasket on both sides by at least 20mm! E.g. rebate = 40mm joint sealing tape must be at least 60mm long
If the joint sealing tape is narrower than the glazing channel, it should be applied on the outside of the window ventilator. - Place the window ventilator over the glass and press firmly Use the correct backfill to he able to seal correctly
- Putty all seams between the glass and the window ventilator.
For the best seal, it is best to do this on both the outside and inside. Especially when mounting above 20m
- Place the g.ass with the window ventilator in the wirdow.
- Attach the glazing bars to the window.
For rebate 25 mm with filler blocks:
The filler blocks must always be completely behind the glazing bar. The glazing bars must clamp onto the fixed part of the end piece!
- Putty according to the rules of the art
Attachments : dry glazing
Option only for DucoMax ‘ZR’ and GlasMax ‘ZR’ in wooden window:

Specific guidelines for window ventilators placed in a moving part according to NPR 3577 (wooden window frames).
It is preferable to avoid window ventilators in moving parts, given the associated negative impact on the structural strength of the moving part. If a window ventilator is yet placed in a moving part, this window ventilator should be fixed on the sides to the post (see figure below).
For mounting window ventilators in hinged parts in plastic and aluminium windows, follow the specific instructions
