Here you will find all the information on the processing of Pilkington Activ™ products.
Can I buy or make Insulating Glass Units (IGUs)?
Can I sandblast the Pilkington Activ™ coating?
No. Any processing of this nature to the coated surface will result in the loss of self-cleaning characteristics permanently wherever the coating is damaged or removed.
Can we safety mark toughened Pilkington Activ™ on the coated surface?
Pilkington recommends that wherever possible, the application of any safety mark should be to the non-coated surface. Where this is not practical however, the coated surface may be marked but great care is necessary.
Does the toughening process affect the colouring of Pilkington Activ™?
Only in cases of excessive temperatures. Pilkington Activ™ is toughened in a similar process to uncoated glass, and if over-heated the self-cleaning properties can be altered.
Can a Pilkington Activ™ IGU be manufactured with a silicone seal?
Yes with care, as long as there is no silicone contact with the Pilkington Activ™ surface, causing contamination at any stage. A silicone sealed unit is normally glazed to ensure moisture does not reach the seal and eventually drain onto the glass.
How do you cover the sealant from UV attack in a stepped unit?
Use a silicone unit seal, or alternatively we would recommend covering the seal with a lead strip. The lead should be treated with Leadshield™ or patination oil to reduce the potential of carbonate run off. In this type of application, run off is generally not an issue as the stepped edge is normally at the bottom of the glazing. Conservatories, however, pose a greater potential risk of run off, carrying lead carbonate from flashing onto the glass roof below. This can lead to marking of any glass type, not just Pilkington Activ™.
