Joinery is not only windows and doors, but also their frames, gates, shutters, blinds, sills and all the components that make their installation and operation possible. It is one of the stronger sectors of the Polish construction industry – and one of the more vulnerable to damage in transport.

In 2023, Poland exported more than USD 2.2 billion worth of products in this category, placing our country in a leading position among exporters worldwide. (Source: Poland Exports of doors, windows and their frames and thresholds by country | Year 2023). Global demand for windows and doors is forecast to grow by 2.8 per cent annually to USD 308 billion in 2028. Among other factors, the increase in market value will be driven by trends supporting higher-value products that are more energy efficient and resilient (source: Global Window and Door Report – The Freedonia Group). However, the growth of this sector comes with logistical challenges, especially in the context of safely transporting fragile and often non-standard products that are not insignificant in weight, size and susceptibility to mechanical damage. Understanding these trends can help manufacturers and distributors adapt their packaging practices to meet changing market demands, for example by strengthening packaging for larger and heavier glazing.
That’s why, in this article, we take a look at the process of packing joinery so that it arrives safely at its destination. Whether you’re a manufacturer, a distributor, an installer or a private individual who just happens to be planning a build or refurbishment project, understanding the importance of proper packing simply matters. Why? Properly secured wide-format joinery arrives at the installation site and, if it gets there in its entirety, it makes a real difference to customer satisfaction, turnaround time or facility closure, as well as affecting costs associated with complaints and replacements.
Why does proper packaging matter? The challenges of packaging joinery
Unfortunately, damage to joinery during transport is not uncommon. Not surprisingly, given the dimensions, weight and susceptibility to mechanical damage, such situations can occur, and not infrequently at that.
Insufficient or inadequate packaging can lead to a variety of damage. Window and door surfaces are prone to scratches and abrasions. Impacts can cause dents and cracks, especially in delicate components such as glazing. Joinery can become deformed and fittings, profiles and mouldings as well as thresholds and other parts can be damaged. The consequences of such damage are severe. Building projects are delayed, additional costs are generated to replace damaged components and, most importantly, a dissatisfied customer can negatively affect the reputation of the supplier and installer
Damage during transport
Strictly carpentry figures are hard to come by, but according to a report by TÜV Rheinland and DB Schenker, as many as 5-10% of photovoltaic modules are damaged during transport – mainly due to poor packaging and handling (source: DB Schenker and TÜV Rheinland develop new logistics system for photovoltaic modules). Although joinery is different from photovoltaic modules, both sectors share the challenges of product delicacy and the need to secure them properly.
Packaging materials recommended for joinery
Given these figures, one can quickly recalculate that the cost of damage to inexpensive joinery can be severe for many companies. Therefore, the choice of suitable packaging materials cannot be random, as it is responsible for ensuring the safety of the products.
- Polyethylene foam (PE)
Polyethylene foam is widely used in the packaging of joinery components, especially those made of PVC and aluminium. Our customers in this sector use it primarily to protect window and door profiles, trims, aluminium thresholds and also delicate system components that are prone to scratches and dents.
Thanks to its structure, the foam is excellent at absorbing shocks and at the same time does not scratch surfaces – which is of great importance for products with a high-gloss finish or decorative films. The material is lightweight, flexible and easy to fit – so it is suitable for both manual packaging and semi-automatic processes. The foam is supplied in various forms and to the required size, allowing it to be optimally adapted to specific products, such as long balcony profiles or wide terrace door frames.
- Bubble wrap
In the joinery industry, it is mainly used to protect window frames, door sashes, roller shutter cassettes and gate panels. It absorbs shocks and protects against point pressure. It works well both as a direct material (product wrap) and as a spacer layer between elements in packages. We supply bubble films in various weights and bubble sizes – also in versions with a skid for easier packaging.
- Cardboard angle brackets
They are used to protect the corners of windows, doors and gates during bulk transport. They protect the edges from dents and abrasions and additionally stiffen the package, preventing the products from moving.
- Stretch film
It is used to wrap finished products and packages on racks or pallets. It provides permanent immobilisation of the load and protects it from dust, moisture and dirt during storage and transport. Used in both manual and machine packaging. In the case of products with delicate surfaces (e.g. lacquered doors, roller shutter boxes), it is recommended that they be protected in advance with foam or bubble wrap so that the stretch film does not come into direct contact with the product surface.
- Foam profiles
Protective profiles made of foam (e.g. U, L, O type) are used as spacers and covers for edges, frames and panels. They adapt perfectly to the shape of the product, thus protecting sensitive areas from mechanical damage.
- Heat-shrinkable film
When wrapped in foil and heated, the material shrinks and fits perfectly to the shape of the product, creating a rigid, robust protective shell. This type of packaging protects against moisture, dust and scratches. Windows and doors are most often packed in it (especially in automatic and semi-automatic processes).
Standards and technologies for packaging window frames
The packaging of joinery requires the use of appropriate materials and techniques, adapted to the type of material from which the products are made. Joinery manufacturers and transport companies use a variety of standards and technologies to ensure safe packaging and transport. Increasingly, automated packaging lines are being used, which wrap windows and doors in stretch film, shrink film, bubble wrap or PE foam and place them in master cartons or place them on prepared racks.
Special protective profiles made of cardboard or plastic, U strips and sheets of corrugated cardboard or polyethylene foam are used to protect the edges and corners, which are placed between the layers of stored windows and doors. The separation pads provide additional cushioning and spacing between the elements. For long-distance or overseas transport, solid wooden crates are often used. The surfaces of the joinery are protected with various types of protective films, including self-adhesive and low-adhesion films, often wrapped in bubble wrap or PE foam.
- Packing window frames
Before packing, window frames should be thoroughly cleaned of dust and dirt, as even minor soiling can leave marks on the paintwork. Depending on the packaging system used, PVC, aluminium and wooden windows are usually packed in stretch film or shrink film. Sometimes stretch foil alone is not enough.
Corners and edges of frames are particularly susceptible to damage, which is why special protective corners and additional padding are used. In this case, both bubble wrap and PE foam will work well to absorb shocks and protect the frame from scratches. When transporting larger quantities or shipping by container, it is advisable to place the packed windows on pallets, transport racks. This makes the goods easier to handle and increases transport safety.
The whole is secured with strong packing tape and strapping. During transport, it is important that windows are positioned vertically (at the correct angle) and in an orderly manner, avoiding laying them flat.
- Packing window frames
Glazing is one of the most vulnerable elements in all joinery. They are easily damaged, scratched or broken. This is why they need to be protected not only from the outside, but also from one another – if they are transported as a package. This is where bubble wrap – either classic or self-adhesive – proves its worth. It absorbs shocks, protects against moisture and, at the same time, does not leave marks on the surface.
The glass panes must not come into contact with each other in order to ensure safe and economical transportation of the glass panes. Many manufacturers, thanks to our recommendations, are now switching to mono-material solutions – e.g. self-adhesive bubble film without stretch and without cardboard. This is convenient and more environmentally friendly: it is easier to unpack, easier to dispose of.
In transport, glass panes should be positioned vertically, at an angle, and supported at full height. Ideally, the glass rack should be parallel to the axis of the vehicle. This reduces the risk of tipping and vibration during travel.
When it comes to packaging long window profiles or door trims, one of the biggest challenges is not just to protect the surface, but to ensure comfort during packaging – especially for repetitive, serial operations. For this reason, more and more joinery manufacturers are opting for bubble wrap with an additional slip, which makes it easier to slide the parts over the surface of the material.
Standard bubble wrap, while providing excellent protection against scratches and shocks, can cause resistance when moving profiles – especially lightweight, flexible PVC parts. To eliminate this, a film with a sliding surface is used which:
- reduces friction between the profile and the film,
- speeds up the packaging process, especially in semi-automatic lines or bulk packaging,
- minimises the risk of material pulling and distortion.
- Door packing
Like windows, doors require careful packaging with suitable materials.
Doors should be transported and stored on a mounting rail (the leaf will not deform under its own weight) in an upright position at an angle of 0-10 degrees, using special shims to prevent scratching. They must be protected from adverse weather conditions, especially from moisture and direct sunlight.
The most important protection should be at the bottom edge of the frame, which is in direct contact with the base of the pallet or rack – here PE foam is usually used to protect against scratches and moisture. Another sensitive point is the corners, which are worth protecting with cardboard or foam angles, with an additional spacer to protect the painted surface.
If sash and frame are transported together, a thin layer of foam should be placed between them to avoid damaging the seals or chafing the coating.
When packing several doors in a bundle, each element should be separated by a spacer, and the areas where strapping tapes or straps are used should be protected by an additional layer of material – such as cardboard or a foam spacer – to avoid dents and surface damage. This arrangement of spacers not only provides physical protection for the door, but also reduces the risk of complaints related to minor abrasions or edge deformation

- Packing of thresholds and door components
All fittings, handles and casings should be transported in separate packaging to minimise the risk of damage during transport. Door thresholds, especially on external doors, also need to be protected from mechanical damage and moisture. In this case, PE foam works best.
- Gate packing
Sectional doors, due to their construction – consisting of interconnected panels – require the protection of both the individual segments and the entire assembly set. The panels are usually laid horizontally and interleaved with PE foam to eliminate the risk of abrasion during transport. The entire assembly is wrapped in stretch film, sometimes with an additional outer carton. Mounting accessories – such as guides, hinges, springs or automatics – are packed separately in individual cartons, often also wrapped in bubble wrap or PE foam. The individual components are labelled and secured so that they are easy to identify on the building site and can be assembled quickly and without damage.
For roller doors, the packaging process is slightly different – the laths are rolled up and protected with PE foam or coated paper, especially with the more expensive decorative coatings.
This is to protect against scratches, pressure and tarnishing of the surface. The coil is packed in a cardboard box or plywood crate, often with additional spacers in the corners. In cassette versions, the entire box is protected with foam, stretch film or angle brackets. Side guides, bottom rail, gaskets and assembly kits are placed in separate packaging – usually in the form of wrapped packages or bulk cartons, suitably labelled. Separating the individual components in this way not only facilitates logistics, but also protects the sensitive control elements and drive mechanisms from accidental damage during transport or storage.
- Packing of blinds
Prior to transport, external roller shutters are protected with protective materials to protect them from mechanical damage and dirt. PE foam is most often used to wrap the box and the guides, as well as protective angles at the corners. The entire unit is additionally wrapped in stretch film and, in the case of bulk shipping, placed in cartons or on pallets. Control elements, such as drives or remote controls, are packed separately and appropriately labelled. Such packaging allows safe transport and easy identification of the components on site.
- Packing of louvre
Blinds, like roller blinds, are susceptible to damage, especially bends and breaks in the slats. They are most often packed in bubble wrap and then in rigid cardboard boxes tailored to their size. Inside the box, additional protection such as cardboard dividers or foam fillings are used to prevent the blinds from moving during transport. Delicate components, such as control mechanisms, can be packed separately in plastic bags, bubble wrap bags or small cardboard boxes.
Summary
Proper packaging of joinery is an investment that benefits all participants in the process – from the manufacturer to the final customer. It protects products from damage during transport and any handling, minimises costs associated with complaints and replacements and, above all, ensures customer satisfaction. By keeping in mind the best packaging practices for different types of materials, knowing the applicable standards and regulations, and paying attention to details during acceptance, we can significantly reduce the risk of damage and ensure that the entire process of delivery and installation of joinery runs smoothly.
