Description
This 15mm render bead is a white PVC corner bead without a mesh wing, sold in 2.5 m lengths. It is the deepest of the three no-mesh corner beads in the Renders World corner bead range, made for the corners where the render coat is at its thickest, and it gives the arris a straight line to be finished against.
The 15mm Render Bead Without Mesh: What You Get
One length is 2.5 m of white PVC angle. The product photograph shows two arms at right angles, each punched with rows of round holes of several sizes, and a raised nose running along the corner where the arms meet. There is no fibreglass wing on either arm.
The photograph has the same shape as the one on the 6 mm and 10 mm listings and does not show the depth of the nose. Two points decide the order:
- Size: the bead is sold as the 15 mm size. Render beads are named by the thickness of render they finish, so measure the coat at the corner itself, where dubbing out or an old coat left in place can make it deeper than on the open wall.
- Wing: the bead has no mesh. PVC corner profiles with a mesh wing are listed separately in the same range.
Choosing the Deepest Size
The size follows the render, not the job title. A 15 mm nose is the right choice only where the finished coat at the corner reaches that depth:
- Coat as deep as the nose: the render finishes flush with the nose and the arris reads as one line.
- Coat thinner than the nose: the nose stands proud of the render. The 10 mm corner bead or the 6 mm corner bead is the size to order instead.
Measure at more than one height on each corner. Where the readings differ from corner to corner, each corner takes the size that matches its own coat.
With a Mesh Wing or Without
A no-mesh bead and a mesh-wing profile suit different build-ups:
- This bead: two perforated arms and a nose, nothing else. It sets the line and the depth of the render at the corner.
- The PVC corner bead with mesh: a corner profile with a fibreglass mesh wing about 10 cm wide. Its maker's sheet places it in external wall insulation systems and asks for the system reinforcing mesh to cover the profile's mesh fully.
If the render at that corner sits on a reinforced base coat and the specification asks for the corner to be tied into the mesh, order the profile with the wing. If the coat at that corner has no mesh layer, this is the bead to order.
Where the wall does take a mesh from a roll, such as Ceresit CT 325 reinforcing mesh, its maker asks for the belts to overlap by about 10 cm and for extra pieces of about 20 × 30 cm to be embedded diagonally at the corners of openings such as windows.
No-Mesh Corner Bead Sizes in the Same Range
| Size | Mesh wing | Listing |
|---|---|---|
| 6 mm | No | 6 mm corner bead |
| 10 mm | No | 10 mm corner bead |
| 15 mm | No | This bead |
A corner bead finishes an arris, where the render turns round the corner of the wall. Where the coat stops against a frame, a soffit or another material, the edge takes a stop bead instead, and the same thickness is listed as a 15 mm stop bead.
How Many Lengths a Corner Takes
Measure every corner where the 15mm render bead will form the arris. Divide each run by the 2.5 m length and round up:
- a 4.8 m corner takes 4.8 ÷ 2.5 = 1.92, so two lengths;
- a 6 m corner takes 6 ÷ 2.5 = 2.4, so three lengths, with the third cut down;
- the two sides and the head of a window reveal are separate corners, so count them separately.
Short offcuts rarely reach a second corner, so a list of corners gives a truer order than a single total of metres.
What to Confirm Before a Large Order
The listing and its photograph give the size, the length, the colour and the fact that the bead has no mesh. They do not give any of these:
- Maker: no manufacturer, product code or data sheet.
- Profile dimensions: no arm width, hole sizes, nose height or wall thickness.
- Fixing: no fixing method or fixing centres.
Where a specification names a particular maker or a fixing method, ring Renders World on 023 8200 2442 with the detail and settle it before the order goes in.
Fitting the Corner Bead
The 15mm render bead is fitted before the render and the coat is ruled off against its nose. Three guides cover the method and the details around it:
- The bead itself: setting the corner, checking the line and working the render up to it, in the corner bead installation guide.
- Openings: how corner, stop and drip profiles meet around a window or door, in render detailing at windows and doors.
- Choosing profiles: which bead belongs on which edge of the wall, in the guide to which render bead for which detail.
Ordering, Delivery and Returns
Renders World processes orders the same day when the stock is there. Put the 15mm render bead lengths in the same basket as the render they finish, so the sizes can be matched to the coat in one go.
- Delivery: quoted by the team after the order; parcels up to 25 kg go next day, always kerbside.
- Collection: from the counter at Unit 9A, Central Trading Estate, Southampton SO14 5JP, Monday to Friday 7am to 5pm and Saturday 7am to 12pm.
- Returns: goods bought directly from Renders World can go back within 14 days in their original condition; special orders and promotion purchases are excluded.
FAQ
Does this 15mm render bead have mesh on it?
No. It is the plain PVC corner bead with perforated arms. Corner profiles with a fibreglass mesh wing are separate listings in the same range.
Which render thickness is it for?
It is the 15 mm size, the deepest no-mesh corner bead in the range. For thinner coats at the corner there are 10 mm and 6 mm corner beads.
How many lengths does a 10 m corner take?
Four: 10 ÷ 2.5 = 4 lengths, provided the corner runs in one straight line from top to bottom.
Who makes this corner bead?
The listing does not name a maker or a product code. If your specification calls for a particular one, ring 023 8200 2442 before ordering.
