FITTING GUIDANCE
Van window fitting, from checks to finish
A clear starting point for fitting bonded windows to a wide range of vans. Read the whole guide before you start, alongside the instructions for your exact glass and fitting kit.
Check your glass before cutting, priming or bonding. If anything does not look right, stop and speak to us first.
CHECK FIRST. FIT SECOND.
Happy with the glass? Check before it is fitted.
Every window leaves our warehouse in excellent condition, but glass can be damaged in transit. On delivery, carefully unpack each window and check both sides and all edges in good light. Report any damage promptly, and check the glass again before handing it to your fitter.
Something you are unsure about?
Send us your order number, window details and clear photos, including a wider view. We can help you work out the next step before the job goes further.
Ask the Camper Glass teamThe right window
Check the vehicle model and year, body type, side and fitting position against your order and the product listing.
The finish you expect
Look for chips, cracks, scratches, blemishes, marks in the black border, or anything about the tint or appearance that concerns you.
Moving parts and seals
For opening windows, check the latch, slider or hinges and seals as directed by the product instructions.
Check the fit before bonding
With suitable help and support, check the intended position and clearance without adhesive.
01 / GET READY
Before you start
The original guide demonstrates a T5/T6 installation. Do not assume the same cut line or fitting method applies to another vehicle, a Safari window or a different glass design.
-
Step 1: Check the fit
Dry fit the glass or measure the opening to check its shape, position and fit.
-
Step 2: Protect the van
Protect the paintwork and interior from metal swarf and window primer.
-
Step 3: Wear suitable PPE
Wear suitable PPE for the tools and chemicals you’re using.
-
Step 4: Clean the bonding areas
Clean the window and the van’s bonding area.
-
Step 5: Prepare the adhesive
If recommended by the adhesive manufacturer, warm the bond cartridges to help the adhesive flow evenly.
02 / THE FITTING SEQUENCE
Prepare, bond and let it cure
Use this sequence to plan and understand the job, different fitting kits have different specifications and requirements, so be sure to follow the manufacturers instructions.
-
Step 1: Cut the opening
Mark out the opening, following the profile of the inner panel. On most models, one or two supports within the window area will need to be removed.
You can start the corners with a hole cutter or a series of small drilled holes. Cut the rest of the opening with an electric nibbler, jigsaw, angle grinder or aviation snips. Take care: the cut edges will be sharp.
Remember: Cutting the opening can release tension in the panel and cause metal around the drainage channels to spring outwards. If this affects the fit, an experienced fitter may need to carefully adjust the metalwork locally so the glass sits correctly and the drainage channels remain clear. Never bend or force the glass, block the drainage channels, or alter structural reinforcement.

Step 2: Prepare the surfaces
Deburr the cut edges and protect them with anti-corrosion paint or a suitable primer. Clean the bonding areas on the van and the back of the glass with a glass preparation wipe.
Apply window primer where required by your bonding system. Measure in from the edges so the primed areas align when the glass is fitted.
Finishing the cut metal edge. -
Step 3: Apply the adhesive
Fit U-trim if you’re using it. Alternatively, carpet lining can cover the cut edge (see video).
Apply the adhesive with the triangular nozzle, keeping the bead even throughout.

Step 4: Fit the window
With an assistant, position the window and press it firmly into the adhesive. Check that it sits evenly without touching the metalwork, then secure it with good-quality masking tape or window fitting tape.
For sliding or opening windows, check that excess adhesive has not blocked the drainage channels.
Supporting and aligning the fitted windows. -
Step 5: Allow it to cure
Follow the adhesive manufacturer’s curing instructions before using the vehicle. Some products may be ready in around 1-2 hours in warm conditions, but colder weather can extend this considerably. Keep the vehicle dry until curing is complete.
Keep the fitted glass supported while the adhesive cures.

BEFORE YOU GO AHEAD
A few fitting questions, answered
What if I notice a small mark or blemish?
Pause the installation and contact us, even if you are unsure whether it is a fault. Send clear photos of the area and the whole window, plus your order number. Do not apply primer or adhesive while you are waiting for advice.
Should my fitter inspect the glass too?
Yes. Ask them to check the product, condition, operation and fitment before any cutting or bonding. Tell them about any concern you have already raised with us, so the work does not continue before it is resolved.
What if I only spot a problem after fitting?
Get in touch and tell us what has happened. Share photos and the fitting details where possible. Checking beforehand helps avoid unnecessary work, but it does not mean a problem reported after fitting will automatically be dismissed.
How long should I leave the adhesive to cure?
Use the times stated by the manufacturer for the exact adhesive, installation and working conditions. Ask us if you cannot find the relevant instructions.
Does this cover every van and window style?
No. The original demonstration is for VW T5/T6 bonded windows. Other vehicles, opening mechanisms and glass designs can need different preparation and fitting methods. Check the instructions for your product or ask us before starting.
WE ARE HERE TO HELP
Ask before you fit. We would rather you checked.
Whether it is the glass finish, the fitting position or a step you are not sure about, speak to us before committing to the installation.
Have your order number, vehicle model and year, window position and photos ready. It helps us understand the question and give you useful guidance.
