One-way mirror tint, frosted glass film, rainbow prism film and blackout film that cling with soapy water, peel off clean and come in rolls for every window.
See the films
Dwersty makes static cling window film for homes, offices and rentals. Every film in the range holds to smooth glass with nothing more than soapy water, so there is no adhesive to scrape off later and a sheet can be repositioned while it is still wet.
The range covers four jobs: one-way mirror tint that keeps the view out by day and rejects solar heat, frosted and decorative film for round-the-clock bathroom and front-door privacy, rainbow prism film that throws colour across a room in direct sun, and blackout film for bedrooms, nurseries and media rooms. Rolls come in widths from 17.5 to 47.2 inches, with a 1-inch grid printed on the backing for straight cuts.
Static cling film goes on with soapy water and lifts off without residue, which suits rentals.
A 1-inch grid on the liner makes measuring and cutting a straight edge simple.
Depending on the film, 80–96% of UV is blocked, which helps furniture and floors keep their colour.
A squeegee, a utility knife and a spray bottle are packed inside the paper core of the roll.
Reflective tint with a mirror face outside. When it is brighter outdoors than indoors you can see out while passers-by see a mirror; the film also reflects solar heat and cuts glare. After dark, with lights on inside, the effect reverses, so curtains are still needed at night.
The darkest one-way tint: about 12.8% of visible light gets through and 94% of UV is blocked.

One rainbow roll and one plain frosted roll in a single pack, for a sunny living-room window and a bathroom at the same time.
* Amazon groups several Dwersty films under one listing, so this rating is shared with other styles in the same listing family.
The rainbow films have no colour of their own: an etched prism surface splits direct sunlight into bands of colour that move across walls and floors as the sun shifts. They work best on windows that face the sun and still soften the view on dull days.
Mirror tint lets you look out at the garden while people outside see their own reflection, as long as it is brighter outdoors. The Black-Silver film passes about 12.8% of visible light, keeping rooms noticeably cooler and calmer on bright afternoons.
Frosted film blurs shapes in both directions at any time of day, so it is the choice for bathrooms and street-facing doors. Light still comes through softly, which keeps a room bright without anyone seeing in.
Blackout film turns a sunny bedroom into a dark one for babies, night-shift workers or a home cinema. Because it clings rather than sticks, it can come down again in the autumn and go back up next summer.
Figures come from the brand’s own listing charts; light transmittance is the share of visible light that passes through.

The same eight steps work for every film in the range. Take your time with the water: the more you use, the easier the film slides into place.
Wash the window thoroughly and remove dust, grease and old sticker residue; any speck left under the film shows as a bubble.
Measure the pane and cut the film on the gridded backing with the knife, adding a little extra on each side for trimming.
Mix a few drops of dish soap into water and soak the glass generously.
Lift the clear protective layer from the cling side, spraying the film as you go so it does not stick to itself.
Lay the wet side on the wet glass and slide it into position; it stays movable while the water is there.
Work the squeegee from the centre outwards until no water or air pockets remain.
Run the knife along the frame, leaving a small gap, and squeegee the edges once more.
Leave the film to dry for a day or two; small haze from leftover moisture clears on its own.
A summary of the common themes in Amazon customer feedback across the range.
Buyers regularly describe installation with soapy water as simple and note that the film comes off cleanly when it is time to move it.
Frosted film is praised for blocking the view from outside while keeping rooms light; one-way tint gets good marks for daytime privacy.
Owners of the rainbow films mention vivid colour patterns on sunny days and say the film is good value for the effect.
Some buyers report edges lifting or poor cling. Spotless glass, plenty of soapy water and a 1/4-inch margin from the frame are the usual fixes.
Paraphrased summary of the “Customers say” highlights on Amazon; not individual reviews.
No. All Dwersty films are static cling: they hold to smooth glass with water and surface tension and lift off without leaving residue.
Yes. Mirror film works only when it is brighter outside than inside. In the evening, with lights on indoors, people can see in, so close the curtains at night or choose a frosted film for 24-hour privacy.
Frosted film such as the white frosted, vine or 3D flower designs. It blurs shapes day and night and still lets soft light in. Rainbow films give only partial privacy and are not recommended for bathrooms.
The film itself has no colour. Its prism texture splits direct sunlight into rainbows, so the effect is strongest on windows that get direct sun.
Frosted, rainbow and blackout films can be peeled off, kept flat on their backing and applied again. Keep the liner and store the film rolled loosely.
No. Static cling needs a smooth, flat surface. On patterned, frosted or cut glass the film cannot seal and will peel.
Measure the glass and choose a roll slightly wider than the pane. Widths run from 17.5 to 47.2 inches and lengths from 78.7 to 157.4 inches, with extra-long 394-inch rolls on some films.
Yes. The one-way films reflect solar heat and block about 80–94% of UV; frosted and rainbow films block around 95–96% of UV, which slows fading of floors and furniture.
Inside the paper tube at the centre of the roll. Tap the tube to slide out the squeegee, knife and spray bottle.
Usually dust or not enough water. Lift the corner, spray again and squeegee from the centre out. Faint haze from trapped moisture fades as the film dries over a day or two.
