A move is one of those moments when even seemingly solid objects can suddenly reveal how fragile they really are. At the top of the problem list, however, glass almost always comes first.
Why does this happen? Three factors are key: shocks, vibrations, and point pressure. During transport, glass is not exposed to one single strong impact, but to hundreds of small impulses: uneven roads, braking, acceleration, and turns. These micro-shocks act continuously and systematically, weakening the glass exactly where it is most vulnerable — along the edges and at the corners.
In this article, we will show how — by using proven solutions from the glass industry — you can realistically reduce the risk of cracks and losses.

Which glass items are most vulnerable to damage?
Not all glass reacts to a move in the same way. The greatest risk concerns items that are large, flat, or heavy, as well as those with exposed edges. These are the areas where stress and micro-damage are most likely to concentrate, eventually leading to cracks.
Glass shelves and countertops
These are among the most frequently damaged items during moves. Long, flat panes behave like flexible plates — even slight bending during lifting, carrying, or improper support in a vehicle can be enough. Situations where the weight rests on just two points, or where a shelf touches a hard surface with its edge, are particularly dangerous. Even tempered glass does not tolerate such conditions well and can shatter suddenly, without any prior visible signs of damage.
Framed pictures with glass
Although they are lighter than countertops, they present a different challenge: a thin pane enclosed in a frame. During transport, the frame “moves,” while the glass inside is exposed to vibrations and point pressure, especially at the corners. Without proper separation, the glass may rub against the frame or other pictures, leading to scratches, chipped edges, or even cracking of the entire pane.
Doors, shower enclosures, and glass panels
These are large, heavy elements and often very expensive to replace. Although they are usually made of tempered glass, their greatest weakness lies in the edges and corners. A single uncontrolled impact or twist during handling can cause damage that only becomes visible later. During transport, vibrations are also particularly dangerous if the glass lacks stable support points.
Decorative and technical glass
This group includes display cases, protective screens, decorative panels, and elements with unusual shapes. They are often thinner than standard panes and have sharp edges, making them particularly sensitive to glass-to-glass contact. Without proper spacers and rigid packaging, even slight movement inside a box can result in scratches or cracks.
The most common mistakes when packing glass
Most glass damage during a move does not result from one dramatic drop, but from seemingly minor mistakes that accumulate throughout transport. Worse still, many of them appear to be “reasonable” solutions — until the boxes are unpacked.
Glass against glass
This is by far the most common and costly mistake. Stacking panes, shelves, or pictures directly against one another — even with a thin layer of paper or film — leads to point contact between glass surfaces. During transport, the elements shift slightly and rub against each other. The result? Scratches, chipped edges, and in extreme cases cracks originating exactly at the point of contact.
Lack of rigid packaging
Bubble wrap, blankets, or stretch film protect against scratches, but do not provide rigidity. Large panes wrapped only in soft materials “work” with every movement of the vehicle — bending, twisting, and transferring stress directly to the edges.
Uneven pressure
Glass does not tolerate situations where the load is concentrated in one or two points. Resting a pane only on its corners, tightening a transport strap in one spot, or contact with a hard structural element causes stress concentration. Even if the glass does not crack immediately, it may be weakened and fail later — after it has already been installed in its new location.
Packing too loosely
Paradoxically, a box that is too “loose” can be just as dangerous as no protection at all. If the glass has room to move, every turn and braking manoeuvre causes micro-impacts. These small, repeated movements lead to scratches, edge damage, and gradual weakening of the pane. Properly packed glass should be immobilised, while still being separated from hard surfaces by a cushioning material.
What should you remember when transporting glass?
Professional glass transport — from construction glazing to large-format mirrors — is based on a few simple rules. The good news is that the same principles can be applied during a home move. Three elements are crucial: separation, cushioning, and controlled support.
Separation of elements
In the glass industry, glass never comes into direct contact with glass. Spacers (for example, made of natural cork) are always placed between panes to maintain a fixed distance and eliminate friction. This prevents micro-impacts to edges and surfaces, even when the load shifts or vibrates. In a home move, this means one thing: every pane, shelf, or framed picture should be physically separated, not merely wrapped in the same material.
Shock absorption
While driving, glass is exposed to constant micro-vibrations. This is why professionals place it on flexible supports and fill empty spaces with materials that absorb movement. Bubble wrap alone is often not enough — what matters is that the glass is in contact with a material that compresses under pressure and returns to shape, rather than transferring impact energy further. This type of cushioning significantly reduces the risk of cracks with no obvious cause.
Controlled support points
Glass does not tolerate random support. In professional transport, panes are usually carried vertically, slightly angled, with even support along the entire lower edge. Additional stabilising points (such as straps) are positioned so that they do not apply pressure in a single spot. In home conditions, it is worth following the same logic: it is better to support glass along its full edge with a soft base than to “hang” it on two corners.
These three principles — separation, cushioning, and controlled support — form the foundation of safe glass transport.
What should you choose to protect glass?
If you look at how glass is protected in professional transport and storage, one solution appears especially often: natural cork or cork-foam spacers. This is no coincidence, but the result of material properties that address the challenges typical of moving.
Natural cork spacers – a proven solution
Natural cork spacers are used to separate panes and maintain a constant distance between them. This prevents direct glass-to-glass contact, eliminates friction, and stops point impacts from being transferred to the edges. This is exactly what is missing when items are packed only in film or blankets, which do not control contact between elements.
The structure of natural cork as a natural shock absorber
Natural cork has a unique cellular structure — it compresses gently under pressure and then returns to its original shape. In practice, this means it disperses the energy of shocks and vibrations instead of concentrating it in one spot. As a result, it acts as a natural shock absorber, protecting glass from micro-impacts during transport.
No scratching and no reaction with the glass surface
Natural cork is a soft, glass-safe material. It does not cause scratches, leave pressure marks, or react with the glass surface. This is particularly important for mirrors, framed pictures, and decorative glass, where the final appearance after unpacking matters just as much as avoiding cracks.
Resistance to compression and vibration
They do not crumble, do not collapse after hours of transport, and effectively dampen vibrations. As a result, glass is protected not just from a single impact, but throughout the entire move.
How should natural cork spacers be used correctly during a move?
For spacers to fulfil their function, correct placement is essential:
-
Edges and corners – these are the most sensitive parts of the glass. Spacers should be placed every few dozen centimetres along the perimeter of the pane, with particular attention to the corners.
-
Centre of the surface – for large panes, countertops, or mirrors, several spacers in the central area help distribute pressure evenly and limit glass deflection.
-
Contact with hard elements – glass should never come into direct contact with cardboard, wood, or frames. The first protective layer should always be a spacer, followed only then by rigid packaging.
When used this way, natural cork spacers make it easy to apply professional glass protection standards in an ordinary home move — significantly reducing the risk of damage.
Summary
Glass requires a completely different approach during a move than most household items. Although it appears hard and durable in everyday use, during transport it is exposed to shocks, vibrations, and point pressure that can easily lead to cracks or scratches — often without a single obvious moment of damage.
As experience from the glass industry shows, safety does not rely solely on “thick” packaging, but on control of contact, pressure, and movement. Separating elements, effective cushioning, and even support significantly reduce the risk of losses, even over long distances.
Natural cork spacers fit perfectly into these principles. They separate glass from glass, dampen vibrations, protect edges, and do not cause scratches. Importantly, they allow professional glass protection standards to be applied in an ordinary home move — without the need to invest in specialised equipment.
FAQ
1. How closely should natural cork spacers be placed between glass panes?
For smaller items, spacers at the edges and corners are sufficient. For large panes, countertops, or mirrors, it is advisable to add them in the centre as well — every few dozen centimetres — to distribute pressure evenly and prevent glass from bending.
2. Is it better to transport glass flat or vertically?
Most large glass panes are safer to transport in a vertical position, slightly angled, with even support along the bottom edge. Transporting glass flat increases the risk of bending and cracking, especially if support is uneven.
3. Can natural cork spacers be reused for another move?
No. Spacers provide maximum protection on first use, when they retain full elasticity. When reused, they may dampen vibrations less effectively, shift more easily, and fail to maintain a stable distance between elements.
