Enclosures help protect from light, dust, handling and impact. They also help protect to some extent from fluctuations in relative humidity, temperature and damage from fire and flood.
An enclosure will also help to keep parts together. For example damaged/detached elements of a book such as a leather spine, boards or leaves can be keep together with the textblock in a suitable archival box - reducing the risk of loss of parts and allowing for an option of future repair using these original parts.
Providing enclosures for your collection is generally accepted as best practice and is an excellent measure to help prevent damage especially for priority collections.
Enclosures made by Triptych are made using archival quality materials and adhesives – and specialist designs incorporating conservation principles.
