Description
Specify 160 mm insulation and the build-up has crossed into deep-renovation and near-Passive House territory, where every U-value target it serves is uncompromising. The Klimas LTX 200 mm is the plug that closes that build-up: at 200 mm overall length, a 10 mm sleeve and 60 mm flange, it is the longest 200-piece variant in the LTX-10 series and the certified anchor for the deepest boards on a standard UK domestic order — held in matched lengths so a deep-spec elevation runs one drill cycle from reveal to main wall.
What the LTX 200 mm Plug Does in a UK EWI System
The Klimas LTX 200 mm polystyrene fixing plug is a hammer-in mechanical anchor certified under ETA-16/0509 to ETAG 014, fixing 160 mm EPS or XPS boards on new-build masonry with a true 30 mm anchorage depth. Supplied in boxes of 200 from the insulation fixing accessories range, it is the longest variant in the standard 200-piece pack format and the length specified once a project reaches the deep-renovation and near-Passive House board depths.
The plug body is polyethylene and the expansion pin is glass-fibre-reinforced polyamide, so no metal pathway runs from masonry to render. Each fixing carries a point thermal transmittance of 0.001 W/K at surface mount and 0.000 W/K when recessed and capped, holding the thermal envelope intact at every anchor across the elevation.
At 160 mm insulation the thermal investment per square metre of wall is at its highest across the domestic specification range, so preserving every fraction of that investment through non-bridging fixings is how a near-Passive House build-up holds its calculated performance from drawing to handover. That is the discipline the all-plastic pin enforces on the deepest builds Renders World supplies.
Why Trade Specifiers Choose the LTX 200 mm Plug
- Built for 160 mm deep-renovation and near-Passive House boards: the 200 mm length fixes 160 mm boards on new-build masonry — the thickness tied to whole-house deep retrofit and projects targeting the lowest achievable domestic U-values — so the anchorage matches the ambition of the specification.
- Protects the largest per-m² thermal investment: at 160 mm board thickness each fixing point represents a proportionally larger area of the thermal plane, and all-plastic construction at 0.000 W/K immersed preserves the U-value the build-up was designed to achieve.
- Retrofit reach to 160 mm over plaster: on walls carrying 20 mm of existing plaster, the plug fixes 140 mm boards at surface mount and 160 mm when immersed, covering the deepest retrofit thicknesses on UK energy-efficiency programmes including PAS 2035 whole-house upgrades.
- Pin stiffness verified at full 200 mm length: glass-fibre reinforcement in the polyamide pin maintains rigidity through a full-depth hammer drive, preventing the mid-shaft flex that shows up in lighter plug designs at maximum standard-pack length.
- 60 mm flange with adhesive-key pockets: the oversized pressure plate keys mechanically into basecoat mortar, which matters most on deep builds where any fixing-point irregularity becomes visible through thin-coat render under low-angle light.
- ETA-16/0509 across the full UK substrate range: the assessment covers concrete from C12/15, solid clay and calcium silicate brick, perforated brick including Porotherm 25, lightweight aggregate block, and autoclaved aerated concrete.

How the LTX 200 mm Plug Installs in a Render or EWI System
The LTX 200 mm enters the ETICS build-up after the adhesive bonding the board to the substrate has fully cured — typically 24 hours on EPS at +20 °C. A 10 mm hole is drilled through the board and 40 mm into the masonry, the plug body is inserted until the flange sits flush against the board face, and the pin is driven home until the head seals against the sleeve collar. Basecoat with embedded mesh then covers the flange and prepares the surface for the render finish that closes the system.
- Fixing density: typically 6 plugs/m² in central zones, 8 at corners and edges, rising to 10 on exposed elevations above 15 m.
- Drilling depth: 40 mm into solid masonry, 60 mm in aerated concrete, drilled around 10 mm deeper than embedment to clear debris.
- Immersed option: recess the plug with an EPS hole cutter and cap with a grey EPS finishing cap for a flush plane and 0.000 W/K per fixing — standard practice on deep-renovation work.
Fixing density is governed by the project wind-load calculation, not a fixed rule. The fixing pattern and spacing calculation method sets out the layout aligned with ETAG 014 wind-load categories, and the step-by-step insulation fixings installation guide covers substrate assessment, drill-mode selection, and pin-drive technique in full.
Installation Notes — Dust Clearance, Bit Reach, Depth Discipline
Dust clearance is the variable that separates reliable anchorage from intermittent pin-drive failures at this plug length. Drilling through 160 mm of EPS and into masonry generates a long debris column, and at 200 mm depth that debris compacts against the hole base unless it is actively removed. The reliable method is three or four back-and-forth passes at reduced speed followed by a single compressed-air burst, which evacuates the fine dust that mechanical passes leave behind.
Drill bit reach is the second variable. A standard 210 mm SDS masonry bit cannot achieve the required total depth of 160 mm board plus 10 mm adhesive plus 40 mm anchorage once chuck depth and operator clearance are subtracted. A 300 mm bit is the practical minimum at this length and restores a normal drilling rhythm across the elevation.
Depth Discipline and Perpendicularity
Use a depth stop set to the correct combined depth and verify perpendicularity every third hole. At 200 mm length a 2° drift at the surface translates to roughly 7 mm of lateral offset at the expansion zone — enough to land the anchorage in a mortar joint instead of the brick face. Immersed mounting keeps each head flush and delivers 0.000 W/K per fixing, which is why it is the default rather than the exception on deep-renovation specifications.
Pro Tips From UK Installers Using the LTX 200 mm Plug
At 160 mm board depth the thermal stakes are high enough that a few tooling and sequencing habits earn their place on every elevation.
- Budget around 20% more time per fixing. Compared with a 140 mm plug, the 200 mm length adds real time through dust clearance, bit retraction, and drive depth — programme it in so the last fixings of the day get the same discipline as the first.
- Clear every hole with compressed air, not just a brush. Mechanical brushing removes loose dust but leaves compacted fines at the hole base; a short air burst clears them and gives reliably flush plug-body seating.
- Default to immersed mounting on every plug. At 160 mm insulation the U-value cost of a surface-mounted fixing is no longer negligible; recessing and capping takes a few seconds and preserves the full calculated performance.
- Replace masonry bits every 350–400 holes. Bit wear accelerates at this depth because the bit spends longer in the substrate; a slightly worn bit oversizes the hole and reduces grip, so a fresh bit holds diameter within the certified tolerance.
- Spot-check three fixings per elevation before basecoat. A brief torque-resistance check on deep-renovation builds gives a useful confidence signal that anchorage quality is consistent across the wall.
How the LTX 200 mm Compares to Sibling LTX Plug Lengths
The LTX-10 range runs nine plug lengths from 70 mm to 220 mm on one shared body, flange, pin, and ETA certification — only the sleeve length changes. The 200 mm sits between the 180 mm Part L compliance plug and the 220 mm maximum-length variant, and Renders World stocks all three so a mixed-thickness elevation runs one drill cycle throughout.
| Variant | Key spec | When to choose |
|---|---|---|
| LTX 180 mm (200 pcs) | 140 mm new-build · 120 mm retrofit | 140 mm Part L compliance |
| LTX 200 mm (this product) | 160 mm new-build · 140 mm retrofit | 160 mm deep renovation |
| LTX 220 mm (100 pcs) | 180 mm new-build · 160 mm retrofit | 180–200 mm Passive House |
Is the LTX 200 mm Plug Right for Your Project?
- Fixing 160 mm EPS or XPS on new-build masonry, or 140 mm boards on retrofit walls over 20 mm plaster: the 200 mm length is the matched deep-renovation specification, paired with a grey EPS cap for a flush finish.
- Stepping down to Part L compliance thicknesses? The LTX 180 mm plug in the comparison table above matches 140 mm boards on standard Part L specifications and is the higher-volume length on most current new-build EPS work.
- Stepping up to Passive House board depths? The LTX 220 mm plug in the table reaches 180–200 mm boards on the thickest certified low-energy specifications, in a 100-piece pack format.
- Need the boards to match? The graphite EPS insulation boards stock 160 mm in matching pack sizes, ready to pair with these plugs on one order.
- Specifying mineral wool for fire-rated or high-rise façades? Higher-density mineral wool and fire-strategy requirements typically call for metal-pin fixings with greater pull-out capacity under current Approved Document B guidance; the wider fixing accessories range includes suitable variants.
FAQ — LTX 200 mm Coverage, Substrates, Ordering
What board thickness does the 200 mm plug actually secure?
On new-build masonry with a 10 mm adhesive layer, surface mounting secures boards up to 160 mm and immersed mounting with a hole cutter extends that to 180 mm. On retrofit substrates carrying 20 mm of existing plaster, the effective range is 140 mm surface-mounted or 160 mm with a cutter. That places the 200 mm plug in the deep-renovation and near-Passive House band; for the thickest 180–200 mm boards, the 220 mm length is the matched anchor.
How many square metres does one box of 200 cover?
At the standard density of 6 plugs/m² in central zones and 8/m² at corners and edges, a 200-piece box covers roughly 25–33 m² of insulated wall. On exposed elevations above 15 metres or in higher wind-load zones the density rises to 8–10/m² and coverage falls to around 20–25 m² per box. A project-specific fixing-pattern calculation under BS EN 1991-1-4 governs the exact figure for any given elevation.
Can I install the 200 mm plug with a standard 210 mm SDS bit?
No — the required combined depth of 160 mm board, 10 mm adhesive, and 40 mm anchorage exceeds the reach of a 210 mm bit once chuck depth and operator clearance are subtracted. A 300 mm bit is the practical minimum, and carrying a spare on every elevation is standard practice. Bit wear accelerates at this drilling depth, so budget for one replacement per 350–400 holes to hold hole diameter within the certified tolerance.
How does the plug perform on lightweight aggregate substrates?
On the LTX-10200 length row the characteristic pull-out is 0.60 kN, which meets the design requirements for standard domestic EPS insulation under typical UK wind-load conditions. On lightweight aggregate block the substrate-category value falls to 0.40 kN, so projects on those substrates in exposed coastal or upland zones benefit from confirming pull-out against the project wind-load calculation. Rotation-only drilling preserves the block's aggregate structure and maintains the certified figure.
What site conditions does the plug install in?
The polyamide pin retains its drive characteristics across UK site temperatures, from cool mornings around +5 °C through to summer heat above 25 °C. As with all ETICS fixings, the underlying adhesive must have reached its manufacturer-specified cure time — most commonly 24 hours on EPS at +20 °C, extended in colder weather — before mechanical fixing begins. Avoid driving plugs into substrates that are visibly frosted or saturated.
Does the all-plastic construction support whole-life carbon reporting?
The polyethylene body and polyamide pin are recyclable thermoplastics, and the cardboard packaging enters standard paper and card recycling streams. All-plastic construction carries lower embodied carbon per fixing than steel-pin alternatives, which supports the embodied-carbon line of a whole-life carbon assessment or PAS 2035 retrofit report. On deep-renovation builds the fixing counts run high, so Renders World holds the full LTX range in matched lengths to keep specification and reordering straightforward.
