Sputter Bronze 35 is extremely popular in homes because of it’s “bronze” look. It matches up with architects aesthetics such as brown bricks and beige painted homes.

This Sputter Bronze film is an advanced technological film with excellent durability and longevity.

From the outside the film has a soft bronzy look and is not very reflective. The benefits of this product is that it rejects 62% of the total solar energy, reducing heat build-up and therefore saving on airconditioning costs. From the inside it is very light as it allows in 37% of the visible light, thereby reducing 63% of the summer and winter glare.

Sputter Bronze blocks 99% of the ultra violet radiation, protecting interior furnishings and fabrics from fading. The film comes in a patented scratch resistant coating and is much tougher than conventional films for durability, easy cleaning and maintenance.
The shading co-efficient which is the overall calculation utilised by architects or airconditioning engineers is .43, which equates to exceptional heat control.

This Sputter Bronze has a low solar absorption factor of 37% and can be safely applied to laminated glass, where it has been used safely over the last 20 years.

This product has a pressure sensitive adhesion, which will lessen the dangers of broken glass. It also conserves winter heat as it retains a portion of the heat generated in a room in winter. This exercise will result in the saving of heating costs during winter months.
