Moving house is one of those situations in which even objects that seem sturdy can suddenly prove how delicate they truly are. At the very top of the list of potential issues, glass almost always takes first place.
Why does this happen? Three elements play a decisive role: shocks, vibrations, and localised pressure. During transport, glass is not subjected to one major impact, but to hundreds of minor impulses caused by uneven roads, braking, acceleration, and cornering. These micro-impacts act continuously over time, gradually weakening the glass precisely where it is most susceptible — along its edges and in the corners.
In this article, we explain how — by drawing on proven practices from the glass industry — you can genuinely minimise the risk of cracks and losses.

Which glass items are most vulnerable to damage?
Not every type of glass responds to a move in the same way. The highest risk applies to items that are large, flat, or heavy, as well as those with exposed edges. These areas are where stress and micro-damage tend to accumulate, ultimately resulting in cracks.
Glass shelves and countertops
These elements are among the most frequently damaged during moves. Long, flat panes behave much like flexible boards — even slight bending during lifting, carrying, or incorrect support inside a vehicle can be enough to cause damage. Situations where the weight is supported at only two points, or where a shelf rests on a hard surface by its edge, are especially risky. Even tempered glass reacts poorly to such conditions and can break suddenly, without any visible warning signs.
Framed pictures with glass
Although lighter than countertops, these items present a different challenge: a thin pane held within a frame. During transport, the frame itself flexes, while the glass inside is exposed to vibrations and point pressure, particularly at the corners. Without proper separation, the glass can rub against the frame or neighbouring pictures, leading to scratches, chipped edges, or even full-pane cracking.
Doors, shower enclosures, and glass panels
These are large, heavy components and often extremely costly to replace. Even though they are usually made from tempered glass, their most vulnerable points are the edges and corners. A single uncontrolled knock or twist during handling may cause damage that only becomes apparent later. During transport, vibrations pose an additional threat if the glass is not supported evenly.
Decorative and technical glass
This category includes display cabinets, protective screens, decorative panels, and elements with unusual shapes. These pieces are often thinner than standard panes and feature sharp edges, making them particularly sensitive to glass-to-glass contact. Without proper spacers and rigid packaging, even minimal movement inside a box can result in scratches or cracks.
The most common mistakes when packing glass
Most damage to glass during a move does not stem from a single dramatic fall, but from apparently minor mistakes that build up throughout the journey. What makes this worse is that many of these methods seem perfectly “reasonable” — until the items are unpacked.
Glass against glass
This is by far the most frequent and costly mistake. Placing panes, shelves, or framed pictures directly against each other — even with a thin layer of paper or film in between — creates point contact. During transport, items shift slightly and rub together. The result is scratches, chipped edges, and in extreme cases cracks originating exactly at the contact point.
Lack of rigid packaging
Bubble wrap, blankets, or stretch film protect surfaces from scratches, but do not provide structural rigidity. Large panes wrapped only in soft materials flex with every movement of the vehicle — bending, twisting, and transferring stress directly to the edges.
Uneven pressure
Glass performs poorly when weight is concentrated in one or two points. Supporting a pane only on its corners, tightening a transport strap in a single spot, or allowing contact with a rigid structural element leads to stress concentration. Even if the glass does not break immediately, it may be weakened and fail later — after installation in its new location.
Packing too loosely
Ironically, packaging that is too “loose” can be just as dangerous as having no protection at all. When glass has space to move, every turn and braking action causes micro-impacts. These repeated movements lead to scratches, edge damage, and gradual weakening of the pane. Properly packed glass should be fully immobilised, while still being separated from hard surfaces by a cushioning layer.
What should you remember when transporting glass?
Professional glass transport — from building glazing to large mirrors — is based on a handful of simple principles. The good news is that these same rules can be applied during a home move. Three factors are essential: separation, cushioning, and controlled support.
Separation of elements
In the glass industry, glass is never allowed to touch glass directly. Spacers (for example, made of natural cork) are placed between panes to maintain a fixed gap and eliminate friction. This prevents micro-impacts to edges and surfaces, even when the load shifts or vibrates. In a domestic move, this means one thing: every pane, shelf, or framed picture must be physically separated, not merely wrapped together.
Shock absorption
While a vehicle is in motion, glass is exposed to constant micro-vibrations. This is why professionals place it on elastic supports and fill empty spaces with materials that absorb movement. Bubble wrap alone is often insufficient — what matters is that the glass rests against a material that compresses under load and springs back, rather than passing impact energy onwards. This type of cushioning significantly reduces the risk of cracks appearing without an obvious cause.
Controlled support points
Glass does not respond well to random support. In professional transport, panes are usually moved vertically, slightly tilted, with even support along the entire bottom edge. Additional stabilising points, such as straps, are positioned to avoid applying pressure in one place. At home, it is worth following the same principle: supporting glass along its full edge on a soft base is far safer than letting it rest on just two corners.
These three principles — separation, cushioning, and controlled support — form the basis of safe glass transport.
What should you choose to protect glass?
Looking at how glass is secured in professional transport and storage, one solution appears again and again: natural cork or cork-foam spacers. This is no accident, but a direct result of the material’s properties, which address the typical challenges of moving.
Natural cork spacers – a proven solution
Natural cork spacers are designed to separate panes and maintain a consistent gap between them. This prevents direct glass-to-glass contact, eliminates friction, and stops point impacts from being transferred to the edges. This level of control is missing when items are packed only in film or blankets, which do not regulate contact between elements.
The structure of natural cork as a natural shock absorber
Natural cork has a distinctive cellular structure — it compresses slightly under pressure and then returns to its original form. In practical terms, this means it spreads the energy of shocks and vibrations rather than concentrating it in one area. 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-friendly material. It does not scratch surfaces, leave pressure marks, or react chemically with glass. This is especially important for mirrors, framed pictures, and decorative glass, where appearance after unpacking is just as important as avoiding cracks.
Resistance to compression and vibration
They do not crumble, flatten after hours of transport, or lose their damping properties, effectively absorbing vibrations throughout the journey. This means glass is protected not just from a single impact, but for the entire duration of the move.
How should natural cork spacers be used correctly during a move?
To ensure spacers perform their role effectively, correct placement is essential:
-
Edges and corners – these are the most sensitive areas of the glass. Spacers should be positioned every few dozen centimetres around the perimeter of the pane, with particular focus on the corners.
-
Centre of the surface – for large panes, countertops, or mirrors, placing several spacers in the central area helps distribute pressure evenly and reduce bending.
-
Contact with hard elements – glass should never touch cardboard, wood, or frames directly. The spacer must always be the first protective layer, followed only by rigid packaging.
Used in this way, natural cork spacers make it easy to apply professional glass protection standards during an ordinary home move — significantly reducing the likelihood of damage.
Summary
Glass requires a completely different handling strategy during a move than most household belongings. While it may seem hard and durable in everyday use, during transport it is exposed to shocks, vibrations, and point pressure that can easily cause cracks or scratches — often without a single clear moment of failure.
As experience from the glass industry demonstrates, safety does not depend solely on thick packaging, but on controlling contact, pressure, and movement. Separating elements, effective cushioning, and even support significantly reduce the risk of damage, even over long distances.
Natural cork spacers fit these principles perfectly. They keep glass separated, absorb vibrations, protect edges, and do not cause scratches. Crucially, they make it possible to apply professional glass protection standards in a typical home move — without the need for specialised equipment.
FAQ
1. How closely should natural cork spacers be placed between glass panes?
For smaller items, placing spacers at the edges and corners is sufficient. For large panes, countertops, or mirrors, it is advisable to add spacers in the centre as well — every few dozen centimetres — to distribute pressure evenly and prevent bending.
2. Is it better to transport glass flat or vertically?
Most large glass panes are safest when transported vertically, slightly tilted, with even support along the bottom edge. Transporting glass flat increases the risk of bending and cracking, especially if the 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 absorb vibrations less effectively, shift more easily, and fail to maintain a stable distance between elements.
