Film Technical Specification
Conservatory Cooling Solar inserts are an innovative and highly advanced system, manufactured using advanced sputter coating metalisation technology, directly embedding aluminium base metals into premium polyester film, ensuring optimum solar rejection properties and colour stability.
This is very important!
By using this manufacturing technique our solar film inserts will deliver high level performance in excess of 15 years. Cheaper less effective manufacturing techniques such as Vapour Coating deliver a lower performance and typical life of only 3-5 years.
Key Points
Conservatory Cooling "Sputter coated" Solar Inserts
- A slow, more intensive manufacturing process, which is reflected in the quality and cost.
- More even disposition of aluminium particles embedded within the polyester film.
- More consistent application of scratch resistent hardcoat to protect the film.
- More stable and consistent shading.
- Delivers premium performance and a life expectancy in excess of 15 years.
- Fit it - forget it.
Other suppliers - Vapour (Vacuum coated) Solar Inserts
- A faster, cheaper and less intensive metalisation process, which is reflected in the quality, price and mass availability.
- More uneven disposition of metal particles and hardcoat, which can lead to demetalisation through oxidisation, corrosion and UV bleaching.
- Can experience inconsistancies in colour stability.
- Solar rejection properties decrease as the film breaks down, with typical guarantees no longer than 3-5 years..
- Risk of replacement after 3-5 year period.
