Conservation boards
PETERBORO CONSERVATION
As the Peterboro Conservation board has almost the same properties of the Peterboro Vantage Whitecore boards, we have decided to remove this range of boards.
If your artwork requires Conservation quality matboards, we recommend upgrading to the Museum cotton board as this board is the best board available.
These boards are made from the purest form of natural cellulose, require little processing, are naturally acid free and maintain a history of performance.
Accordingly, every board of this premium line adheres to the Fine Art Trade Guild's stringent specifications for museum matboards and we have recently been granted a licence by the FATG as an accredited manufacture of them.
Available in the most popular 7 neutral colours

Below you will the facts on Conservation board so you can make a comparison to our Peterboro Vantage Whitecore boards we use.
SOME KEY FACTS ABOUT PETERBORO CONSERVATION
1. The Core
We use high grade Alpha Cellulose as the main ingredient in our conservation core. Alpha Cellulose can be distilled from cotton or wood, the higher the Alpha Cellulose content the higher the purity of the board. We specify that PETERBORO CONSERVATION core must have more than 90% Alpha Cellulose, industry specifications call for no less then 84 %.
2. Chemical ingredients
The conservation quality of a mat can often be affected by the chemical impurities within its materials. For instance the level of iron and copper within the matboard can create tarnishing and discoloration of the mat while the sulphur content can raise acidic levels that attack both mat and artwork. In the manufacture of PETERBORO CONSERVATION we strictly control the level of chemical ingredients to ensure that they meet or exceed the Library of Congress and Fine Art Trade Guild standards for chemical composition.
3. Surface Paper
To reduce color fade and bleed PETERBORO CONSERVATION uses pigments for surface paper coloration. Our pigments are specified to meet or exceed the fade and bleed test requirements outlined by the Fine Art Trade Guild standards. Independent testing shows that PETERBORO CONSERVATION exceeds these requirements.
4. Backing Paper
Our backing paper is 100 % virgin fiber, buffered with calcium carbonate at a 3% minimum reserve, no optical brighteners, and a smooth finish with even coloration. Our backing paper meets or exceeds the standards as set out by both the Library of Congress and the Fine Art Trade Guild.
5. Quality
Independent QC benchmarking shows that PETERBORO CONSERVATON has one of the highest standards of consistent quality in the market.
