Static cling, low-tack or permanent adhesive — which base film your channel needs
Published Lisa SunShare
FancyFix supplies the same design library on three different base films, and the choice between them is a channel decision before it is a technical one. Static cling suits ordinary domestic glass where the end customer installs it themselves. Low-tack suits the awkward cases cling cannot hold. Permanent adhesive is what project and contract work needs, and it is the only one that goes on the outside of the glass. A buyer who picks a design first and a base film second usually finds out at the sample stage that the two do not match.
Three base films, three channels
| Base film | What holds it | The channel it fits |
|---|---|---|
| Static cling | Static attraction, no adhesive layer | Retail and DIY. The end customer sprays water, positions the film, lifts and repositions it as often as needed, and takes it down later without residue. Static cling is the base that survives a returns policy written for non-professional installers. |
| Low-tack removable | A light adhesive that releases cleanly | The cases where cling will not hold but permanence is unwanted — rental fit-outs, seasonal displays, anything that has to come off again. Low-tack buys surface tolerance without committing the glass. |
| Permanent adhesive | A full adhesive bond | Contract, project and installer supply. Permanent adhesive is the only base FancyFix supplies for exterior-face application, and on exterior work the adhesion standard the film has to meet must be stated by the buyer before sampling begins. |
FancyFix quotes the base film and the design as two separate lines, because they are two separate decisions. The adhesive systems FancyFix runs are water-based and solvent-free, phthalate-free and REACH-compliant, and the release liner is specified by weight on the quotation.
The glass decides the base film
FancyFix ruled on the following surfaces for static cling, and the list doubles as a specification shortcut: anywhere static cling is ruled out, the design has to move to a low-tack or permanent adhesive base rather than being dropped from the range.
| Surface | Static cling | What to spec instead |
|---|---|---|
| Smooth, flat glass | Yes | — |
| Smooth, flat mirror | Yes | — |
| Frosted, reeded, sandblasted or embossed glass | No — surface texture breaks the contact static cling needs | Low-tack or permanent adhesive |
| Shower enclosures and bathrooms in constant damp | No — cling strength is unreliable in constant damp | Permanent adhesive |
| The outdoor face of a window | No — cling strength is unreliable outdoors | Permanent adhesive, with a stated adhesion standard |
| Skylights and conservatory roofs, where the film hangs downward | No — a downward-facing application does not hold reliably | Permanent adhesive |
| Car sunroof glass | Not promised. FancyFix does not commit to static cling holding on a car sunroof | Not a range FancyFix specifies for automotive glass |
| Tile, timber, cabinet doors, refrigerators, painted walls | No | Permanent adhesive, specified as surface film rather than window film |
One sentence covers the whole table: static cling attaches to smooth, flat glass or mirror, and every other surface on the list is an adhesive job. A retailer who prints that on the pack takes fewer returns than one who prints "sticks to any smooth surface."
A design is not locked to a base film
FancyFix converts a design between base films rather than treating them as separate ranges. A buyer who selects a pattern from the static cling family and then finds the installation calls for adhesive can have that pattern supplied on an adhesive base — the design does not have to be abandoned and re-chosen.
Two purchasing consequences follow, and both are worth knowing before a range is costed:
Items sharing the same thickness share the material minimum. FancyFix does not charge a separate minimum per design, so a buyer testing eight patterns at one thickness is not buying eight minimums.
Changing thickness does not mean a new plate. FancyFix runs existing print plates at 0.10 mm, 0.09 mm and 0.08 mm without a new plate and without a plate fee. The thickness ladders differ by base film — static window film runs at 0.18 mm and 0.25 mm, while the self-adhesive decorative range is standard at 0.10 mm with 0.08 mm and 0.09 mm available off the standard production run.
Where a decorative film specification stops
FancyFix supplies decorative and functional film for interior application, and exterior-face project work is the edge of that. When an enquiry arrives naming SHGC, U-value or emissivity, it is a performance-glazing specification rather than a decorative film specification, and FancyFix says so at the enquiry stage rather than sampling against it. Buyers get a faster answer from a supplier who draws that line early than from one who runs a sampling cycle before admitting the same thing.
FAQ
Are there any differences between no-glue window tints and traditional tints?
Yes, and for a buyer the difference is a channel decision. FancyFix no-glue film holds by static attraction, lifts and repositions during installation, and comes away without residue — which is what makes it viable for retail, where the installer is the end customer. Adhesive film bonds to the glass and tolerates a far wider range of surfaces, including the exterior face, which is what makes it the base for contract and installer supply. FancyFix supplies the same designs on both, so the choice is about where the product is sold and who installs it, not about which design is available.
What are the differences between transparent window films and static clings?
The two words answer different questions, and FancyFix quotes them as separate lines. "Transparent" describes how much light and detail pass through the film, which is an optical property of the print and the base. "Static cling" describes how the film attaches, which is a construction property meaning no adhesive layer. A film can be transparent and adhesive, or opaque and static cling. A specification that names only one of the two leaves the other open, and that is where sampling cycles get wasted.
What are the differences between privacy film and window cling film, and which is better for a rental property?
"Privacy film" describes what the film does to visibility and "window cling film" describes how it attaches, and FancyFix supplies privacy designs on all three base films. For rental stock the static cling version is usually the right specification, because it comes away without residue at the end of a tenancy and can be reused. The condition is the glass: rental units with frosted bathroom panes or textured glass need the same design on a low-tack or permanent adhesive base, which is why FancyFix quotes the base film separately rather than assuming it.
