How to replace an alu window cremon step by step
Complete technical guide for artisans and maintenance professionals
On a renovation site or during a troubleshooting operation, the aluminium window creamone is one of the most sought after hardware parts. Repeatedly manipulated, it ends up using, blocking the opening mechanism or preventing the sealing of the flap.
1. Tools for intervention
Before you start disassembly on your site, make sure you have the necessary aluminum carpentry tools:
| Tool | Specific use on aluminium carpentry |
|---|---|
| Allen key set (six panels) | Essential to loosen the screws of the handle and connections. |
| Cruciform or flat screwdriver | Adapted to the mounting screws of the creamone plate. |
| Professional backstage foot | To measure precisely the attachment (E) and length of the shafts. |
| Silicone technical lubricant | To fluidize the passage of new rods in the throat of the profile. |
2. Ultra-fast identification of the part with the Scan IA
The main point of friction when replacing an old hardware store is the identification of the original brand (Fapim, Giesse, Savio, Master, Technal, Schüco, K-Line...), often erased by time.
Instead of searching through hundreds of pages of paper catalogues, use DirectAlu.com. Take a clear picture of the Cremona removed from several angles. Our industrial visual recognition algorithm, developed in partnership with Open Global Solutions (OGSo), instantly analyzes the geometry of the part and directs you to the exact reference or the stock-compatible repair kit, available in a few days across Europe.
3. Step by step guide for replacementStep 1: Secure carpentry and remove handle
Open the window in the intermediate position. If the cremone is completely blocked in a closed position, gently place the mats to clear the opening. With a Allen key, loosen the dot screw under the aluminum window handle and remove the handle and its square drive rod.
Step 2: Remove the defective cremon
Rotate the mounting plate cover to access the main support screws. Unscrew them completely. Pull gently on the box of the cremone to remove the profile. Be careful not to let slip the internal locking rods inside the opening throat.
Step 3: Uncoupling the closing rods
The cremone activates the lock via sliders connected to the window rods. Record scrupulously the position of the ergots or connecting pins. Uncouple the worn cremone from these rods. Take advantage of this to clean the throat of the profile with a clean cloth to remove the silt and old grease residues.
Step 4: Install and Connect the New Alu Creamone
Take your new Cremone ordered from DirectAlu.com. Position the cursors of the new case in perfect correspondence with the notches of existing rods. Insert the mechanism into the profile housing. Screw the screws by hand in a first step to ensure that the thread is aligned correctly, then lock them firmly in the screwdriver.
Step 5: Place the handle and make adjustments
Reinsert the square axis of the handle into the cremon hub. Squeeze the locking screw. Before closing the window permanently, turn the handle several times blank to check the flexibility of the movement. Lock points must deploy and retract without any hard points.
