Conservation Framing: Protecting What You Buy
By Njeri Wachira · 26 August 2026 · 1 min read
Conservation framing costs more upfront for one concrete reason: acid-free materials and UV-filtering glazing are what actually stop a work degrading behind the glass.
Cheap framing and conservation framing look similar from the front. The difference is entirely in materials you can't see once the piece is hung — and it's the difference between protecting a work and slowly damaging it.
The mat and backing board
Standard mat board is often acidic, and acidic material in direct, prolonged contact with paper causes yellowing and brittleness over years — visible, irreversible damage that shows up as a discoloured border matching the mat's shape exactly. Acid-free, conservation-grade mat and backing board cost more because the material itself is different, not because of the labour.
The glazing
Standard glass or acrylic offers little to no UV protection; UV-filtering glazing measurably slows the fading that direct and even indirect light causes over time. For any work you intend to keep long-term, this is the single highest-value upgrade in a framing job.
The mounting method
How a paper work is actually attached inside the frame matters as much as the materials around it — reversible mounting methods (corners, hinges) that don't permanently adhere the paper to a backing let a future conservator undo and correct the mount if needed; permanent glue-down mounting can't be undone without damage.
Why this is worth the extra cost specifically in this region
Given the humidity and UV considerations covered in our piece on East African climate conservation specifically, the case for paying for conservation-grade framing here is stronger, not weaker, than in a more temperate climate — the materials are doing real, measurable work against real, regional conditions, not just adding cost for its own sake.
