GENERAL

Les pellicules de protection pour vitrage 3M™ sont installées par des applicateurs sélectionnés et formés. Presque toutes nos pellicules sont destinées à être appliquées sur les surfaces internes du vitrage.

La première étape est la préparation de la surface vitrée pour l’application ce qui inclut la protection du sol et/ou le retrait du mobilier si nécessaire.

Ensuite, le vitrage est nettoyé en utilisant simplement une solution de nettoyage (souvent de l’eau et du savon doux) et un grattoir. Puis, nous pulvérisons la pellicule avec une solution détergente, nous la positionnons et l’appliquons sur le vitrage. En utilisant une raclette professionnelle et en suivant la bonne technique de pose, nous terminons l’application en retirant l’excès d’eau, en appliquant bien les bords et en les asséchant avec la raclette.

We suggest allowing up to 30 days for the laminate to fully dry and cure. During the curing process, it is normal to have small water bubbles and/or hazy appearance. These will disappear as the laminate dries. Under extreme low temperatures or high humidity conditions, it may take longer than 30 days to completely dry.

No. 3M Safety and Security Laminates require professional application by Certified Dealer/Applicators who are thoroughly trained and experienced in performing high quality installs that can be warranted by the manufacturer.

After 30 days, you may clean 3M Safety and Security Laminates using a normal household cleaning solution, including ammonia based products. Abrasive products that could scratch or damage the laminate should not be used.

3M Safety and Security Laminates are made to last for many years, depending upon the type of the laminate applied, the type of glass it is applied to, and the particular climate in which it is applied. Most installations last well beyond the 10-year warranty and several installations are over 25 years old.

3M adhesives are designed to bond the laminate to the glass for many years. Yet when it is time to remove the laminate, removal can be performed by the following relatively simple process:
First, try to pull the laminate off by lifting and peeling the laminate from the corner. If removing the laminate is difficult, spray the laminate with a solution of detergent and water and cover with a plastic film (e.g. polyester garbage bag will work). Allow to soak for several hours not in direct sunlight or overnight. Now try step one again.
Next, the adhesive residue left on the glass can be sprayed with a sudsy ammonia and water solution and scraped with a razor blade.

3M Safety and Security Laminates are warranted to maintain their properties without bubbling, peeling, cracking or crazing. All 3M Safety and Security Laminates are warranted against discolouration. Should the product prove to be defective, 3M and the Certified Dealer/Applicator will replace the laminate (and caulking if applicable) and provide the removal and re-application labour at no charge to the customer. Length of warranty is 10 years for commercial installations.

The application of clear 3M Safety and Security Laminates will not affect your sunlit glass including double pane or insulated units. Combination films can increase the temperature of the glass, which in turn can increase the stress on the glass edges. The quality of those glass edges and several other factors (external shading, interior shading, glass history, type of laminate, size/shape of glass, indoor/outdoor temperature) all contribute to the potential risk of thermal glass breakage with or without film.

No. Clear 3M Safety and Security Laminates have no material effect on the glass. 3M has installed several million square feet of Window Laminate on insulated units over the past 40 years. Combination 3M Sun Control and Safety/Security films applied to the room side of an insulated glass unit can result in some absorption of the sun’s energy, which will increase the temperature of the glass pane. Some of the heat will transmit to the airspace, slightly raising the airspace temperature. However, even a 20 F degree increase will result in a less than 3% change in air pressure, whereas properly made units are designed and tested to withstand 22% changes in air pressure. Risk of seal failure is greatly determined by the quality of workmanship and the quality of the materials that go into the manufacturing of the insulated unit. The best guard against seal failure is to purchase well-made units from a reputable window manufacturer that has solid experience and a history with insulated units.0

SECURITY

3M Safety and Security Solutions have been used effectively for a wide variety of commercial applications to protect people and property from security and safety issues related to glass. 3M Safety and Security Laminates are designed to make glass shatter-resistant by holding the glass pieces together when broken. These laminates are usually thicker than sun-control films and incorporate a more aggressive adhesive. Depending on the application, the laminate may be called upon to deter forced entry or mitigate the effects of blasts and catastrophic weather.

No laminate or window film is bullet/burglar/bomb/hurricane proof. They are designed to make the window glass more shatter-resistant. In the event of a windstorm or an earthquake the laminates offer a significant safety and security value. They can reduce the risk of injury from flying shards of broken glass and possibly help prevent debris and water penetration through the window depending on the severity of the storm or earthquake, the type of glass, framing system, size and velocity of the objects. Bullets: laminates or window films are not designed to stop bullets regardless of media propaganda. If bullet resistance is required, use properly manufactured ballistic-rated products that consist of a hybrid construction using polycarbonates and glass (i.e. Prel-Secur Glazing by Prelco Montreal).

3M invented window film in 1966. Stronger versions of window films or laminates were developed in the 1970s to address international concerns and needs for improved safety and security against terrorist acts of bombings. The laminates can significantly reduce the risk of serious injury from flying shards of glass due to blasts, however much depends upon the severity of the blast and the proximity of the window glass to the blast, the type of glass, framing system and other factors. In the battle against Burglaries or “Smash and Grab” crime, the laminates have been proven to be very effective. The tough, shatter-resistant qualities of the laminate can hold the window glass together, even if a brick or similar object were actually to pass through the glass. The thief must now make a choice: continue to attack the window, try another window or move on.

UV PROTECTION

While screening of Ultra Violet radiation helps to protect furnishings, it has no adverse effects on plant health. This is because the photoreceptors in plants typically absorb in the visible light wavelengths of 450 nm to 460 nm and 620 nm to 720 nm.

No, the ultra-violet protection will last for the life of the laminate due to the UV inhibitors within the adhesive layer, which is desirable since the adhesive layer receives the direct UV rays from the sun and blocks almost all of it before it reaches the polyester layers. It does not lose its effectiveness over time.
