Question Larger than 60 x 60 inch mats

Rising Mats has boards available 60" x 104". That's the biggest matboard I'm familiar with. Our local sign supplier carries AluPanel brand ACM in 78" x 120". That is the direction I would go if I needed bigger than 60".

Thanks @Lafontsee That's Aluminum?
It's Aluminum Composite Material, thin aluminum on either side of a polyethylene core in much the same way as foamcore is paper on either side of a foam core. It's used increasingly in framing. It accepts spray paint well and the surface is considered archival. If you do a search on The Grumble for ACM you'll find plenty of discussions about it.

Crescent has over-oversized mat boards, limited colors...
C2283 white 60x104
C2289 Antique White 60x104

Rising has that size in 4 colors: Warm White, Antique, Black, and White. That these size boards exist is only half the battle. Getting them to your shop, and cutting them can be a logistical challenge.
 
Mats that scale can get a little problematic. On option is to use a flat plain moulding profile
with a bevel edge and paint it. Not everybody's thing but can be a lot less work and hassle than
trying to cut a 60" mat. Bear in mind that you have to raise the glass away from the painted surface
as you can get strange optical effects when it touches the glass.

Yeah. This or a fabric covered liner might be a simpler option at that scale.

Thank you. I did know about these mats. What I need is a mat for something 70 x 70 or so. Larger than 60 x 60 in both dimensions.
Rising has 72" x 104" mats in White and Warm White.

Really? I can't seem to find that. Do you know who sells it?

thanks,
Harry
 
Legion Paper now owns Rising. I usually deal with Michael Ambrosio for purchases. The phone there is 212-683-6990 and the extension for sales is 4003. You may not be able to purchase from them directly, but they may be able to help you find a distributor that handles that size sheet (if they still make it).
Like I mentioned earlier, logistics is going to be the real challenge in this deal. Shipping could well exceed the actual cost of the product. Finding a distributor is hard enough for their 48" X 96" products, hence my willingness to buy a big enough order to buy direct, and stock the over sized sheets (up to 60" X 104").
 
The OP said he needed larger than 60" on both dimensions. I've never seen any matboard larger than 60x104.
 
The big sheets may be gettable, but there is the matter of the logistics of shipping a sheet that size without
a crease or a knock. It would be easier to transport if you had 5-6 sheets, but who wants to do that? 😐

Me too, but one of the posters said that Rising makes a 72" X 104", and I figured the best way to confirm is to contact the manufacturer.
I just checked their web site and 60" X 104" is the largest size they list.
I think that achieving over 60" in both directions will involve splicing.

What are you attempting to accomplish? What are you framing, what are the dimensions? What is the look you're going for? What are the solutions you've already come up with for the other issues regarding a frame that is over 60 x 60? Moulding? Structure? Backing? Glazing?

Where are you at?

It seems like I was mis-remembering.
I had just ordered 60 x 104 matboard, and 72 x 96 plexi.

Sorry.
 
As well as the aesthetic aspect of a mat, the main purpose is to allow the art to be stored and handled when
not in a frame. Public galleries have lots of matted works in drawers that they don't have room to display framed.
These can be viewed by academics by arrangement and safely handled. The concept on a book-mat means that
the top mat can be flipped back to reveal the entire artwork without touching it. When you get to 5ft mats this is
a bit silly as the sheer bulk of the thing would make safe handling tricky.
When you come to things that require a mat bigger than standard size board it's often good to think outside the box
and devise another method. There is no virtue in making a huge traditional mat save for the look.
One of my suppliers here in the UK stocks two flat plain wood sections - both 70mm wide and 7mm thick. One has a
coved edge and the other a bevel. Easy to cut and underpin a 'mat'. In theory you could do one as big as the lengths.
The caveats are the you have to paint it, but in the process you can make the miters disappear.
The glass needs to be raised slightly or you get weird effects where it touches the glass. Not a huge prob. The wood needs
to be 'normalised' at room temp/humidity for a day or two prior to joining to mitigate shrinkage cracks. Also the back needs
isolating from the artwork. The good thing is it's far more rigid than card and the deep bevel looks great.
 
This an 'out of the box' solution I've done a few times.

The drawing is chalk/charcoal done on a full sheet of std matboard (47x 32"). It needed to be under glass and
the customer requested a mat. The mat would have been very unwieldy and I couldn't cut one on my matcutter anyway.
The whole frame would have been very heavy with glass in.
I made a frame from 1/2" plain cushion moulding to fit the board, with a bit of wiggle room and lined the inside with
aluminum tape the isolate the wood. Painted off-white. The glass goes on top of this. (fortuitously 48" long). Around this
is a 3" panel moulding also painted. This gives the 'matted' appearance but the glass area and therefore weight is reduced
considerably. (Still a big lump, but managable).

** The one in the photo is slightly smaller but same principle. 😉
