National Gallery of Scotland Store

Context

A simple brick building was acquired as a storage space for artworks. The media changes regularly but is typically works on paper and canvas as well as sculpture of various materials including plastics.

Issue

The building had only a very basic electric heating system – designed to protect against frost. It needed to be upgraded to allow for control of relative humidity and to prevent too low temperatures that might lead to embrittlement of some of the objects. An improved heating system was required.

Intervention

A wall mounted humidistat was recommended together with portable electric oil filled radiators. This was installed and the conditions monitored on an ongoing basis. Considerable adjustments were needed to start with, including some changes to incorrect wiring. Conditions were gradually brought under control over a period of 6 months and then further improved when recommendations to improve the building were implemented.

Outcome

The space now provides a good stable environment that prevents problems with the collection. Relative humidity moves around within a safe zone. Temperature falls a little lower than ideal but this can’t be prevented without installing air conditioning.
