What is Thinsulate 3M film protection?

3M Thinsulate Window Film is an insulation plastic film with low emissivity (Low E). Emissivity is the amount of thermal radiation naturally expended by an object; the lower the emissivity, the less heat an object radiates. 

Windows are over 30 times less insulated than roofs and walls, meaning that most of the heat gained or lost is through glazing. Replacing your windows can be costly and time consuming. 3M protective film is specifically designed to help you compensate for this deficit by providing up to 40% better insulation in your building.

How does Thinsulate work?

Thinsulate Window Film has the capacity to reflect heat in warm weather and retain heat in the cooler months throughout the year. Its unique design allows it to block up to 99% of UV rays, adding protection to art, furniture, hardwood floors and window frames and other interior mouldings. 

With 3M Insulating Window Film, you can increase the insulation performance of a standard single-glazed window and replicate the insulation effect of a double-glazed window.  It’s easy to install and, depending on the building and external conditions, it can even perform close to a triple pane window.

FOR OFFICES

It is known throughout the industry that offices and other commercial properties lose around 40% of their heat through poor or old glazing. Thinsulate window film can increase the insulation performance of commercial windows by up to 40%. This is a clear contribution to reducing a property’s heating and air conditioning costs!

FOR LISTED BUILDINGS

Thinsulate Window Film can be applied to both plain and patterned glass, without compromising aesthetics or efficiency for listed properties. Our 3M Thinsulate Window Film also provides UV protection for antique objects, carpeting and furnishings. This will help preserve historical items for listed properties and also bolster modern energy efficiency to the building.

THINSULATE ROOF INSULATION FOR CONSERVATORY GLASS 

Insulating the glass roofs on conservatories or industrial green houses will ensure the whole property is fully protected. Heat typically builds up quicker in spaces where light falls directly from the top, creating a very uncomfortable environment. Thinsulate window insulation films will preserve the optimal temperature allowing you to enjoy the indoors, wherever you may be.

Benefits of Thinsulate Window Film

There are many benefits to 3M Thinsulate Window Film. With solar, energy control and UV protection all in one, 3M insulation film is often a solution to the most common glazing issues, including temperature loss, excessive heat gain and fading of furniture, upholstery and artwork.
