Aluminium system installation is a process where workmanship matters just as much as the material itself; even a high-quality profile can start leaking air or water, or loosen over time, if it is fitted carelessly. In this guide we walk through the stages of aluminium system installation, the points that deserve attention, and mistakes worth avoiding. Along the coast in Famagusta and across North Cyprus, salt-laden sea air, strong sun and occasional strong wind make careful installation even more important, so every stage deserves close attention.
Preparation Before Installation
Accurate measurement and a site survey are the most critical step before installation begins. Wall, frame and floor dimensions, the condition of any existing joinery, and infrastructure needs for systems that require power or motors, motorised pergolas or shutters, for instance, are all identified at this stage. Measurements taken during the site survey and measurement stage feed into project design, and manufacturing is planned accordingly. Skipping or rushing this step can lead to a frame that does not fit the wall opening on installation day, a sash that hits furniture when opened, or glass cut to the wrong size.
Installation Stages
1. Site Preparation and Removal
In renovation projects, any existing joinery, shutter box and surrounding plaster or sealant is carefully removed first. The wall opening is cleaned, and any structural issues such as dampness or cracks are noted by the installation team. In new builds, the shell tolerances, meaning the size of the opening and any vertical or horizontal deviation, are checked.
2. Frame Installation
The frame is positioned in the wall opening and aligned using a level and plumb line. If horizontal and vertical accuracy is not achieved here, sash balance and lock or hinge alignment will suffer later. The frame is then fixed using anchors, screws or dowels suited to the wall structure, with fixing points spaced according to the system's size and wind load.
3. Insulation and Joint Detailing
The gap around the frame is filled to ensure air and water tightness, and interior and exterior joints are sealed appropriately. This step matters especially near the coast, where wind-borne salty moisture can work into poorly sealed joints over time and encourage staining or corrosion. Drainage holes must stay clear so rainwater can be carried away from the frame.
4. Sash and Glass Fitting
Once the frame is fixed, sashes are hung and hinge and lock mechanisms are fitted. Glazing needs particular care: the glass is seated in the sash using gaskets and setting blocks. If the blocking is done incorrectly, the glass can shift under its own weight, the sash can hang crooked, or gasket pressure can become uneven.
5. Adjustment and Mechanism Check
Sash opening and closing, full lock engagement, and, on sliding systems, track and roller alignment are fine-tuned at this stage. Even gasket pressure all the way around matters both for weather sealing and for long-term durability. On motorised systems, pergolas or shutters, the motor and sensor connections are tested.
6. Cleaning and Final Inspection
Once installation is complete, the area is cleared of sealant residue, protective film and construction dust. Sash operation, locking, any motorised movement and drainage holes are checked one last time, which helps catch small adjustment issues early.
Points That Deserve Attention During Installation
- Level and plumb check: even small misalignment in the frame can throw off sash balance.
- Filling the wall gap: insulation material should fill the gap completely, without voids.
- Drainage holes: weep channels must stay open and never be sealed over with paint or sealant.
- Fixing points: outdoor and exposed locations such as terraces, gardens or facades need enough correctly placed fixings for the wind conditions.
- Glass blocking: setting blocks need to sit in the right positions so the glass's weight is evenly distributed on the sash.
- Site safety: handling large glass panels or working at height calls for the right equipment and precautions.
Common Installation Mistakes
One of the most frequent mistakes is fixing the frame quickly without checking level and plumb, which can leave doors and windows swinging open on their own or becoming hard to close over time. Under-filling the wall gap is another common issue, leading to both heat loss and whistling draughts in windy weather. Sealing over drainage holes is also seen too often, letting rainwater pool in the frame and encouraging interior moisture over time. Skipping or misplacing glass blocks can let the glass shift under its own weight and throw off lock and hinge alignment.
Why Installation Needs Extra Care in the Cyprus Climate
In Famagusta and other coastal parts of North Cyprus, climate conditions call for extra care during installation. The long, sunny summer means materials expand and contract, so joints and fixing points need to allow for this. Salty sea air can encourage corrosion on exposed metal surfaces and poorly sealed joints over time, so coating and sealing details need to be applied carefully. Winter rain and moisture or condensation also make correct drainage and joint sealing essential. Occasional strong wind calls for fixing details sized to the system, especially on large glazed systems and outdoor structures such as pergolas, shutters and facades.
Staying in Touch Through the Process
A good installation is not just about the site crew's workmanship; it depends on every stage, from survey to final check, being coordinated. Systems prepared to measurement during manufacturing are fitted on site as part of the installation service. Staying in contact for any adjustment needs after installation helps the system perform well for years to come.
Frequently asked questions
How many stages does aluminium system installation involve?
Installation generally moves through preparation, frame fixing, sealing, sash and glass fitting, adjustment and final inspection. The detail of each stage varies by system type, window, door, pergola or shutter, but the underlying logic is similar.
Where do most installation mistakes happen?
The most common issues are fixing the frame without checking level and plumb, under-filling the wall gap, sealing over drainage holes, and skipping glass blocking. These can lead to air or water infiltration and mechanism problems over time.
What should be checked when replacing old joinery?
The old unit should be removed without damaging the wall, the resulting opening cleaned, and any structural issues such as dampness or cracking assessed. The new frame is then aligned and fixed into this cleaned, checked opening.
Does the Cyprus climate call for special precautions during installation?
Salty sea air, strong sun and occasional strong wind make joint sealing, fixing details and coating quality even more important. When these are applied correctly, the system's performance benefits over the long term.
Why does the final inspection matter?
The pre-handover check confirms that sashes open and close evenly, locks and mechanisms work properly, and drainage holes remain clear. It helps catch small issues early, before they turn into problems during everyday use.
