8mm Polycarbonate Protection
Makrolon Longlife Clear 293 Polycarbonate (8mm) is a very good material for the protection of stained glass windows and leaded lights.
Due to its exceptional impact strength it is virtually unbreakable even at very low temperatures. It is also an excellent deterrent to attempted break-ins.
We generally fit polycarbonate which is 8mm in thickness. We use discreet non-ferrous stainless steel brackets, s/s screws, s/s washes and s/s rivets. We cover each light and item of tracery separately. The combined effect is that the sheet and fixings are almost invisible from many angles. The stained glass window is therefore fully protected and can be viewed clearly from the inside.
The polycarbonate is U/V stabilised on both sides, which enables the sheet to retain its transparency, only losing about 4% of light transmission in 10 years. All the fixings and materials are compatible with the fabric of the building and have no long or short term ill effects.

OTHER POINTS TO NOTE
* The existing stained glass is thoroughly cleaned before protection.
* The polycarbonate acts like double glazing keeping the church much warmer.
* No maintenance because of the stainless steel fixings and longevity of the polycarbonate
* Polycarbonate resists combustion from persistent exposure to naked flame.
* A space of 3 to 4 mm is maintained between the polycarbonate and the stone surround to allow a free flow of air, preventing any build up of condensation.
* We have been granted VAT zero rating on all polycarbonate protection to listed buildings.
* NOTE: We favour 8mm becuase it's thickness gives extra rigidity.
