Description
Every starter profile in this range is bought on one number, and for this one the number is documented at source. The 33 mm is the narrowest width appearing in the manufacturer's published plinth profile table, which makes it the first size in the insulation fixing accessories range where carton quantities, available lengths and material all come from the maker rather than from a supplier description.
What the Manufacturer's Table Confirms About the 33 mm Profile
Listed at £6.00 per 2.5 m length in August 2026, the base track 33mm 2.5m appears in the PROFIGIPS plinth profile table as code AC, the narrowest documented width, supplied in cartons of twenty and carrying the lowest course of insulation.
That table is the reason this page can state more than its narrower neighbour can. Everything below either sits in a row that names this width or is marked for confirmation at order, with nothing filled in from a neighbouring size.

What the 33 mm Actually Measures
The manufacturer's column heading reads thickness and gives 33 mm, without defining whether that is the channel opening or the board depth the channel is built around. Both readings circulate in the trade, and the document settles neither, so the board depth this profile holds is worth confirming in one call before a full elevation is ordered.
Why a 33 mm Starter Track Earns Its Place on Site
The appeal of this width is that it is the smallest one with a paper trail behind it, and that changes what a specifier can put in front of a client.
- Documented at source. Material, code, carton and pallet quantities all come from the maker's own table, so a specification query has somewhere to land.
- Aluminium at the wettest point of the build-up. The profile sits at the base of the system where splash-back and run-off concentrate, and the manufacturer describes the plinth profile as carrying a drip cap that throws rainwater clear of the façade.
- £2.40 per linear metre for a component that sets the datum every board above it inherits — the cheapest place on the wall to buy accuracy.
- Two kilogrammes a length keeps small orders in the parcel network rather than on a pallet, which matters on a job needing a handful of lengths rather than a carton.
- Sits under either insulation family, graphite EPS insulation boards or slab-format mineral wool insulation, with board depth taken from the system specification rather than from the profile name.
Installing the 33 mm Profile Without Losing the Line
A starter profile is a levelling job before it is a fixing job. The line goes up first, the fixings follow it, and the run gets checked before any adhesive reaches the wall.
- Project one datum across the whole elevation with a laser rather than transferring a chalk line piece by piece, which clears the accumulated error before the last opening. The first-day base track routine covers the method.
- Set out fixings to the centres in your system specification. Centres, plug type and embedment are system figures rather than profile figures — the fixing pattern and spacing method shows how a layout is worked out.
- Fix into the structural substrate. Where old render or a soft outer skin is present, the fixing needs to reach sound masonry behind it; the guide to installing insulation fixings covers substrate assessment.
- Leave the movement gap your system states at butt joints, so seasonal movement in the metal stays out of the basecoat above.
- Deburr every cut with a flat file — a snipped aluminium end left sharp will score the back of a board during seating.
Drip Detail and Mixed-Width Runs
Where an elevation carries more than one profile width, hold every length to the same projected line so the base of the render reads as one continuous detail. The maker also lists a separate clip-on drip profile that suits all plinth profile widths, which is the route worth pricing on an exposed elevation or a low-set track close to splash-back.
Where the 33 mm Sits Against the Other Stocked Widths
The standard ladder varies on one dimension, and Renders World stocks it end to end so a mixed-thickness elevation runs from one supplier on one datum.
| Profile | Size | Position in the range |
|---|---|---|
| 23 mm starter track | 23 mm | Narrowest stocked, below the documented table |
| 33 mm starter track (this page) | 33 mm | Narrowest documented width |
| 53 mm starter track | 53 mm | Entry width for main-wall courses |
| 93 mm starter track | 93 mm | Mid-range main-wall width |
| 163 mm starter track | 163 mm | Widest in the standard ladder |
Is This the Right Width for Your Detail?
- Take the 33 mm where the specified depth at that point matches what this profile holds, confirmed at order.
- Step down to 23 mm for the thinnest board work, accepting that no manufacturer table covers that width.
- Go to 53 mm or wider for main-wall courses, with every profile set to one datum.
- Working below the damp-proof course? The plinth zone usually takes water-resistant XPS foundation boards rather than façade board on a starter profile.
Ordering the 33 mm Track: Cartons, Weight and Delivery
A single length of base track 33mm 2.5m weighs 2 kg on the listing, and the carton arithmetic decides how an order travels. Renders World confirms carriage after the order is placed, because weight and dimensions vary too widely across the catalogue for an automatic quote.
- A full carton is 20 lengths, 50 linear metres and about 40 kg (20 × 2.5 m; 20 × 2 kg), so it travels as freight rather than parcel.
- Twelve lengths is the parcel ceiling — 25 kg ÷ 2 kg = 12.5, so 12 lengths at 24 kg stay inside the small-parcel band.
- Small parcels to 25 kg go next day; pallets to 1,200 kg go next day, or two business days on the economy option.
- Free local delivery over £300 within 15 miles of the Southampton base, then £1.50 per additional mile to a 60-mile limit.
- Deliveries are kerbside, between 8:00 and 17:00, so arrange handling from the roadside.

Common Questions About the 33 mm Starter Track
How many lengths should I order?
Measure the run and divide by 2.5 m, then add a length for cuts. Twenty metres of base line gives 20 ÷ 2.5 = 8 lengths, plus one spare. Past sixteen lengths a full carton of twenty is usually the tidier buy.
Which board depth does this profile hold?
The manufacturer's table gives 33 mm under a heading reading thickness, without stating whether that is the channel opening or the board depth it is designed around, so this is the one figure to confirm with us at order. Matching profile to specified depth is a two-minute check that keeps a whole elevation consistent.
Is the 2.0 m length available as well?
The maker produces this profile in both 2.0 m and 2.5 m, and the 2.5 m is what is stocked here. On a run that divides neatly by two metres the shorter length can cut waste, so it is worth asking before a large order is placed.
How should the profiles be stored before fitting?
Flat and under cover. Pallets arrive shrink-wrapped but not weatherproof and delivery is kerbside, so a dry space near the scaffold protects both the profile and the programme. Lengths stored flat stay straight, which counts for more on a datum component than on anything else in the build-up.
