Picture Framing Materials

Below is a brief overview of elements of the frame and the materials used for framing art on paper.


Mouldings, which are generally made of wood, constitute the picture frame. A wide range of different colours, features and profiles are available for you to choose from at Harcourt Framing.


Many framing jobs require glazing to protect the artwork from the damage that pollutants in the atmosphere can cause. 2mm float glass can be sufficient however we also stock Water White Art glass which is almost invisible and reduces light reflection dramatically. In some cases glass giving UV protection will be recommended.

Window Mount

The window mount maintains a space or border between the outer picture frame (moulding), and the picture itself. The windowmount also provides a space between the glass and the artwork. As a general rule, most artwork looks better when a windowmount is included within a frame as it helps to draw the eye in toward the image.

Harcourt Framing recommends that conservation boards are used to preserve your artwork as these boards have virtually all the lignin removed. Lignin generates acid as the board ages. The bevelled edge of the window mount will not turn brown over time if conservation boards are used.


The undermount provides a protective layer between the artwork and the backboard. Harcourt Framing recommends conservation boards are used.


Finally the backboard is fitted to the framed unit thus adding further protection. This is held in securely with framers points and then traditional brown gummed tape is used to seal the back of the frame.

Appropriate fixings will be attached to enable you to hang the picture. Felt bumpers stuck to the bottom corners of the frame prevent the frame touching and marking your wall. These bumpers also increase air flow around your framed art which is beneficial in the conservation process.
