Perspex on stairs instead of spindles?

The first thing you need to do, is check with your local authority governing the building codes in your area. You need to know what is required by the building codes, and if you need any permits for the work.

Most building codes call for a maximun space between the spindles....that space being small enough a child would find it difficult to put their head through. This can also be done by installing a solid sheet product, such as tempered (safety) glass, and some areas might allow acrylic....you NEED to know for certain what your local authority will allow.

PPG is a worlwide supplier of glass products...everything from vehicles to buildings, and it's fairly easy to find one of their sales offices (if nothing else ask at a local automobile dealer).

Perspex is one brand of acrylic...here in the USA it's commonly called Plexiglass (another brand name that has come to stand for the product).... Lexan is a large manufacturer of acrylic sheets, in clear, tinted, and even in a variety of colors, and styles.
