frequently asked questions
What is the ideal humidity level for a mixed collection?
The ideal range is 40–60% Relative Humidity (RH) to ensure the stability of various materials. While this 40–60% range is the standard for most museum and archive environments, significant damage often occurs not from the level itself, but from rapid changes. By maintaining a consistently controlled environment, you protect sensitive items like wood, paper, and textiles from the physical stress caused by constant expansion and contraction.
How do your systems prevent mould growth without damaging delicate surfaces?
We prevent mould by keeping RH levels reliably below the 70% germination threshold using precision controls. Mould thrives in damp, stagnant air, but our systems work to keep your environment well within the range. We use high-accuracy sensors to ensure there are no spikes in moisture that could lead to condensation. To protect delicate surfaces, we favour technologies like evaporative cooling or dry-mist humidification, which add moisture to the air without leaving any damp residue or droplets on your artefacts.
Can humidity control systems be integrated into historic buildings without invasive ductwork?
Yes, we can install discreet, non-invasive systems designed specifically for the constraints of historic and listed buildings. Rather than using heavy ductwork, we can recommend modular units that can be tucked away in existing cupboards or voids. Every building is unique, so we offer a friendly, free of charge site visit to chat through the best subtle options for your space.
How do you monitor for "micro-fluctuations" that cause material fatigue?
We use high-precision sensors that detect tiny environmental changes in real-time, allowing the system to react before damage occurs. Micro-fluctuations are small, rapid shifts in humidity that can cause materials like ivory or oil paint to crack over time. Our sensors act like a constant pulse-check for your room, providing steady data to the humidification equipment. This creates a proactive close-control environment where the system makes tiny, invisible adjustments to keep conditions stable, effectively preventing material fatigue.
