Side glazing for a roof chop

[simon]

Hey Guys

I have just done a roof chop and I am after some help for my side glazing (front and rears are sorted and safety approved/stamped)

The code of construction states

Side glazing maybe made from non-shattering mar-resistant polycarb acrylic etc.

My question is is there a name for this product that cert guys prefur and is easily sourced? Also dose anyone know were I can source some. I just want to check if there is a recomended product before I go out and buy some thing that maybe wrong or not the best out there.

Any help will be awesome

Cheers

Hi Simon

The HCTM has a section which covers glazing requirements.

There are a number of plastic materials on the market that meet the requirements of 15.7.1 and 15.7.2. These materials include ‘Lucite SAR’ (‘SAR’ meaning scratch and abrasion resistant); ‘Lexan MR’ series (‘MR’ meaning mar [‘mar’ meaning scratch] resistant); ‘Cyrolon AR’ series (‘AR’ meaning abrasion resistant); and Tuffak CM-2.

‘Lexan’, ‘Cyrolon’, and ‘Tuffak’ products are all polycarbonates, whereas ‘Lucite’ is an acrylic.

The best products for automotive use are polycarbonate materials which will bend almost indefinitely, whereas acrylic will only bend a small amount and then break, leaving a sharp edge (less than ideal in a roll-over situation), so check out what the products that you are looking at are made from.

I hope this helps.
