Description
Every insulated wall starts at the bottom, and the base track 53mm 2.5m is where it starts in most Renders World EWI kits. It is an aluminium starter profile in 2.5 m lengths: fixed level along the base of the wall, it holds the first course of insulation boards, shields their lower edge and has a drip on the front that sheds rainwater. It sits with the other render fixings and starter tracks in the shop.
Where the Base Track 53mm 2.5m Is Used
The track goes on first, before any adhesive or board. Its maker, PROFIGIPS of Poland, sells it as a plinth profile or starter trim (code AC) and makes each width to match a thickness of polystyrene or mineral wool board.
The 53 mm width is the one built into the shop's own systems. Every Atlas package in the EWI system bundles lists a 53 mm base track among its parts, together with a clip-on profile and 50 mm insulation:
- the Atlas Basic bundles;
- the Atlas Standard bundles;
- the Atlas ULTRA bundle.
Reasons to Choose the 53 mm Track
- The kit width. It is the track every Atlas EWI bundle in the shop is put together with, so extra lengths match a bundle you have already ordered.
- Aluminium with a drip. The drip along the front edge keeps rain running down the render from tracking back into the base of the wall.
- A guarded bottom edge. The lowest edge of the insulation is the one most exposed to knocks and splash-back; the profile covers it.
- Trade quantities. PROFIGIPS packs this width 20 lengths to a carton — 50 m of track (20 × 2.5 m) — and 5,000 lengths to a pallet.
- Other widths, same profile. Narrower and wider widths are stocked, from 23 to 163 mm, for walls where the board thickness changes.

Fitting the 53 mm Track
Before you fix anything, hold an off-cut of the board you will use against the base track 53mm 2.5m: the width should match the insulation at the base of the wall. Then:
- Strike a level datum line along every elevation, and carry it round the corners.
- Fix the lengths to that line with fixings suited to the wall, keeping the front edges in one straight run.
- Fit a clip-on profile onto the front of each length. It brings its own drip nose and a glass-fibre mesh wing that runs up the face of the insulation and is bedded into the base coat — the shop advises buying the same number of clip-on profiles as tracks.
Above the Damp-Proof Course
Set the datum line above the damp-proof course, so the track and the boards it carries stay clear of it, and keep the line continuous round external corners.
For the boards that go on next, see the EPS insulation boards; the day-one routine is set out step by step in the starter track guide for external wall insulation.
53 mm and the Other Widths
The family differs in width only; length is 2.5 m throughout. Choose the width that matches the board at the base.
| Track | Width | Length | Maker's carton |
|---|---|---|---|
| 23 mm base track | 23 mm | 2.5 m | — |
| 33 mm base track | 33 mm | 2.5 m | 20 |
| 53 mm base track (this track) | 53 mm | 2.5 m | 20 |
| 83 mm base track | 83 mm | 2.5 m | 20 |
| 93 mm base track | 93 mm | 2.5 m | 20 |
| 103 mm base track | 103 mm | 2.5 m | 20 |
| 163 mm base track | 163 mm | 2.5 m | 10 |
Choosing the Width for Your Wall
Measure the insulation at the base of each elevation. Where it is the same all round, one width does the job; where it changes, use the matching width on each stretch and fix them all to one level line.
Ordering, Delivery and Collection
Work out the order from the perimeter: the base of the wall in metres divided by 2.5 m, rounded up, plus a spare for corners. An 18 m house front needs 18 ÷ 2.5 = 7.2, so eight lengths and one spare.
- Dispatch: same day when the tracks are in stock.
- Delivery: the team contacts you after the order with the most cost-effective way to send it. Parcels up to 25 kg can go next day; pallets next day, or in two business days on the economy option. Deliveries are kerbside.
- Collection: at the Southampton counter, Unit 9A, Central Trading Estate, SO14 5JP — Monday to Friday 7am to 5pm, Saturday 7am to 12pm.
Tracks in their original condition can be returned within 14 days of purchase from Renders World; the terms are on the cancellations and returns page.
FAQ — 53 mm Base Track
Is this the track in the Atlas EWI bundles?
Yes. Every Atlas bundle sold by Renders World lists a 53 mm base track with a clip-on profile, so the base track 53mm 2.5m sold here matches them.
What thickness of insulation does it suit?
PROFIGIPS matches each width to a board thickness. In every Atlas EWI bundle sold by Renders World, the 53 mm track goes with 50 mm insulation boards. Check with an off-cut of your own board before fixing a whole run; thinner boards take the 33 mm track, thicker ones a wider width.
What is it made of?
Aluminium, with a drip formed along the front edge.
How many lengths are in a carton?
Twenty, which is 50 m of track. The base track 53mm 2.5m is sold as single lengths as well.
Does it need a clip-on profile?
The clip-on profile is the partner part: it fits onto the front of the track and its mesh wing is bedded into the base coat. Order one per length of track.
