Step by step instructions on how to apply window film & frost glass

Regardless of the type of window film or stickers you purchase, the principle will be the same. We also have several targeted video tutorials which you will find by clicking here

Glass Preparation (the crucial task)

Glass preparation before applying window film.

Make a slip solution using a few drops of washing up liquid mixed with water in a spray bottle and toughroughly clean the glass. Use a glass scraper to remove specks of paint.

Film Cutting

Unless your film is already cut to size, and if the film has a paper liner with a metric grid, measure your glass at the top and bottom, and left and right and mark and cut your film. You can also cut the film bigger than required and trim the film once applied to the glass.

Film Application

A. Throughroughly wet the glass with the slip solution.

B. Place the film face down an a flat surface and expose a small amount of the adhesive or cling side.

C.  Spray the adhesive or cling side liberally with the slip solution as you peel off the protective liner.

D. Slip the adhesive or cling side of the film on the glass butting one edge and the top against the window frame or rubber gasket (double glazed unit).

 

Squeegee Technique

A. Liberally wet the face of the film with the solution to act as a lubricant fro your squeegee or felt edged tool.

B-C. Squeeze out the solution from under the film using a firm and even pressure, starting from the top and working your way down and accross the film.

Film Trimming

Run a credit card and a retractable knife blade down the edge of the glass to trim any excess film. The thickness of the card will allow for a small gap to help any remaining solution to be squeezed out. Once trimming is complete go over the film once more to squeeze out all the solution. 

Final Checks

1. Make sure that all the solution has been squeezed out.

2. Wipe the film and any remaining solution with paper towel.

3. Inspect the film on both sides of the glass to check for any trapped solution or air bubbles.

How To Remove Window Film

Removing window film can be a very easy process, but it all depends on how long the film has been on the glass, and the type of film that was used.

Here's a video tutorial which shows the basic principal.

Typically, films are either made using PVC or PET.

PVC is  a soft material which can be peeled off the glass with a glass scraper. Any glue residue can be removed with soapy water and a scraper.

PET is a brittle material widely used for solar and safety film, and might be made of layers of mettalised material. To remove this type of film, use a wide glass scraper and lubricate with soapy water to remove the film.

As a rule, old PET film are more difficult to remove than PVC films.

For large panes, it is best to first score the film into strips with a sharp knife. This means that you can tackle it in more manageable pieces.

 

How To Care For Your window film After Installation

Window film is very easy to look after and you won't need any special products to clean it with. In fact, soapy water, similar to the solution you used to apply the film is the best cleaning product. 

Do's

Wait for at least 3 weeks before first cleaning your film

Use soapy water

Use a soft cloth or paper towel

Use a rubber edged squeegee (unless the film is printed or has cut outs) in good condition

Don'ts

Do not use abrasive products

Do not use Amonia based products

Do not use defective or damaged squeegees

Caring for printed films, or films with cut-outs

Extra care must be taken when cleaning printed films, or films which have been cut out and have exposed edges. Gently clean with a soft cloth only, and take particular care around the cut areas. Do not rub too hard or use a squeegee as it could damage the print or your cut film.

Caring for static cling films & stickers

Take extra care around the edges and clean your sticker or film from the centre out. Do not use a squeegee.

Product Description

  • Helps prevent heat gain
  • Save on air conditioning costs
  • Helps prevent fading of furnishings
  • Limited loss of natural light
  • Ideal for retail outlets
  • Buy by the metre (1.52m and 1.0m width)

Our SER-50 Heat Rejection Film is solar control film designed to prevent slow wave infrared components responsible for heat gain, from going through the glass and into your room. It will reduce ambient temperature by a few degrees therefore making your office or room more comfortable, and help you save on your air conditioning bills. It will also help in limiting heat loss in the winter therefore saving on heating costs.

This product is ideal for home or office, and can be applied internally on any glass surface. This film is truly revolutionary as it is virtually clear with just the lightest of blue colouring, therefore enhancing your comfort without the draw back of the loss of natural light associated with reflective and tinted films. 

This film is very popular with businesses who want to save on their air conditioning costs, including retailers where applying tinted film on shop fronts is not an option, and offices with large windows which require constant temperature control with no loss of natural daylight.

Please Note:
This product doesn't act as an air conditioning unit and is not designed to keep a constant temperature in a room. It is designed to help reduce ambient temperature by a few degrees and therefore save on air conditioning costs. 
For a more efficient product, please consider using a tinted or reflective film instead, but you will have to sacrifice natural daylight. Please check product Specifications for glass compatibility.

Samples
Not sure whether this is the right film for your purpose? We offer free 10cm x 10cm samples. The pictures depicting the film are only for illustration purposes, so a sample is recommended to make an educated choice. If you'd like to try a larger piece before committing to a large order, just order a small amount of film, or a cut to size piece to test on a pane.

Returns and refunds
We will only accept returns for films purchased by the metre. Just send it back to us in it's original condition and packaging. We cannot accept returns for films cut to size however, as they have no resale value.

Will this film reduce the heat by several degrees?

It all depends on a range of factors. If you have a large room with small single pane windows, then the effect would be more felt than if you had a large south facing double glazed window in a small room. On a large building with hundreds of windows, the cost benefits would be greater than in a small office with a couple of windows.
