Description
The base track 23mm 2.5m is the narrowest starter profile Renders World sells for external wall insulation: a 23 mm wide track in 2.5 m lengths, sold one length at a time. It is fixed level along the bottom of the wall before the insulation goes on, so the first row of thin boards has a straight line to stand on. It is stocked with the other EWI plugs, fixings and tracks.
What the Base Track 23mm 2.5m Is For
A starter track is the first part of an insulation system to go on the wall. Fixed at the bottom of the elevation, it:
- gives the first course of boards a level line to start from;
- closes off and protects the bottom edge of the insulation;
- marks where the render system stops at the base of the wall.
The 23 mm width is for the thinnest board on a job — a narrow return or a stretch of wall where there is little room for insulation.
Why Choose the 23 mm Track
- The slimmest width in stock. When the board at the base is thinner than the next width up, this is the track that fits it.
- One length at a time. It is sold by the single 2.5 m length, so a short run or a single detail takes only the lengths it needs.
- One line with the wider tracks. Fixed to the same datum as a wider width, it keeps the base of a mixed-thickness wall straight.
- Easy to work with. A 2.5 m length can be held, levelled and fixed by one person.
- The rest of the base detail in one place. The clip-on profile and the wider tracks are on the same shelf.

Fitting the 23 mm Track
- Hold a piece of the board you are fitting against the base track 23mm 2.5m before you fix a whole run — the board and the track width should match.
- Mark a level line along the base and fix the lengths to it with fixings that suit the wall.
- Check the run with a level before the adhesive goes on.
- Fit a clip-on profile to the front of each length; its mesh wing is bedded into the base coat. Renders World suggests one clip-on profile per length of track.
The whole set-up is covered in the EWI base track installation guide.
Keeping One Line
Where the 23 mm track meets a wider one, set both to the same height and check the joint with a long level. A step at the base shows in the finished render, and it is far quicker to correct at track stage.
The Other Base Track Widths
Each track is 2.5 m long; only the width changes. If your board is thicker, move up the table.
| Track | Width | Length |
|---|---|---|
| 23 mm base track (this track) | 23 mm | 2.5 m |
| 33 mm base track | 33 mm | 2.5 m |
| 53 mm base track | 53 mm | 2.5 m |
| 83 mm base track | 83 mm | 2.5 m |
| 93 mm base track | 93 mm | 2.5 m |
| 103 mm base track | 103 mm | 2.5 m |
| 163 mm base track | 163 mm | 2.5 m |
Is 23 mm the Right Width?
- Yes — when the board at that point of the wall is the thinnest on the job.
- No — when the board is thicker than the track: move to the 33 mm width or wider.
Ordering, Delivery and Collection
- How many: the run in metres divided by 2.5 m, rounded up. A 6 m return needs 6 ÷ 2.5 = 2.4, so three lengths.
- Dispatch: the same day when the track is in stock.
- Delivery: quoted by the team after you order, choosing the most cost-effective way; parcels up to 25 kg can go next day. All deliveries are kerbside.

FAQ — 23 mm Base Track
Which board does the 23 mm track take?
A thin one. Hold an off-cut of your board against the track before fixing; if it is thicker than 23 mm, use the 33 mm track or a wider one.
Can I buy just one length?
Yes. The base track 23mm 2.5m is sold by the single length.
What else goes with it?
A clip-on profile for each length, fixings for the wall, and the insulation boards themselves.
Can I use it next to a wider track?
Yes. Fix both widths to the same level line, so the base of the wall stays straight where the board thickness changes.
Can I collect it?
Yes, from the Southampton counter during opening hours.
