Cold aisle containment that costs a fraction of a hard-wall system. We have supplied NextDC and Rachtech.

Cooling a server costs more over its life than the server did to buy. That makes airflow the biggest lever you have on running cost, and it is decided at fitout, not afterwards.
An open cold aisle leaks. Conditioned air comes up through the floor grid, and if the ends of the aisle are open it spills into the room instead of going through the racks, which is where hotspots come from.
Every watt spent pushing air that never reaches a server shows up in your power usage effectiveness. Containment is the cheapest way to move that number.
Strip curtains close the ends of the cold aisle. With a pelmet running from the top of the racks to the ceiling, the conditioned air has nowhere to go except through the servers.
The appeal is cost and flexibility. Strips go in fast, cost a fraction of a hard-wall containment system, and can be moved when the rack layout changes, which it will.
Techs walk straight through with a rack unit in both hands. There is nothing to prop open, so the containment you commissioned is the containment you still have at the next audit.
Containment is four things working together. Get any one wrong and the conditioned air finds another way out.
Perforated floor tiles
Conditioned air is pushed up through the floor grid into the aisle between two rows of racks. This is the air you have already paid to cool, so everything after this is about not wasting it.
Clear PVC strip curtain
Strip curtains close both ends. This is the part we supply. Clear PVC so techs can see down the aisle, and strips rather than doors so nobody has to put a rack unit down to get through.
Pelmet
A pelmet closes the gap above the racks. Without it the cold air simply rises over the top of the row and mixes with the hot return, which undoes the containment.
Nowhere else to go
The air then has nowhere else to go other than through the server. That is what closing the ends and the top buys you, and it is what flattens the hotspots.
Plexiglass ceilings and sliding doors at the aisle ends do the same job. Which one suits comes down to cost and who specified the fitout. We will tell you straight if strips are the wrong call for your site.
Clear PVC so techs can see down the aisle. Prices exclude delivery and were taken from the live catalogue on 20 August 2026.
We have no genuine quote for this one yet, so the section is switched off rather than filled with something invented.
It depends on your starting point, your rack density and how leaky the room is now. The mechanism is not in dispute: air that cannot escape the aisle goes through the servers. We are not going to quote you a percentage we cannot stand behind.
Cost and flexibility. Strips go in quickly, cost a fraction of a built system, and move when your rack layout changes. A hard-wall system is tidier and may suit a purpose-built hall better.
The strip curtain and its head section is our part. The pelmet, floor grid and rack layout are the mechanical contractor's. We also supply Rachtech, so your contractor may already be buying our material through them.
Yes, that is the main advantage over a door. The strips part when you walk into them and fall back behind you, so nobody has to put a rack unit down to open anything.
Talk to us before you specify. Standard PVC suits most rooms, but if your build has a specific antistatic or fire requirement we need to know at quote stage rather than after delivery.
Yes. NextDC, including the Airport West site, has strip curtains on its cold aisles. We also supply Rachtech, who work across this sector.
Most of this work reaches us through the builder or the fitout designer rather than the operator. If you are specifying a data hall, send us the aisle dimensions and rack row length and we will price the aisle ends.
If strip curtains are the wrong answer for your site, we will say so. We would rather tell you now than be the reason a containment strategy underperforms.
The page links out to these. They are the official sources, not competitors.
These are the things we could not confirm ourselves. The page cannot go live until they are sorted.
You said on the 10 Aug call you would dig out the link. We could not find it, so the page currently links Google's PUE page instead, which does not mention strip curtains at all. A source that does would be much stronger for a specifier audience.
It is the strongest line on the page and it is yours from the call, but we have no source for it. Specifiers check things. We would rather cite it properly or soften it.
This is a genuine guess from the verified range. You supply Rachtech in this space so you will know what specification actually goes out.
We have written an FAQ saying to talk to you at quote stage. If there is a product we should name it. If there is not, we should say so plainly.
This is the only page in the set with no photographs. Data halls are restricted so it may need the client to supply them, or permission to shoot.
Agreed on the call. We draft it, he reviews and approves, so it is minimal work for him. A named Australian case study would carry this page.
You said builders come to you, and that this suits direct outreach with the trade contact list more than organic search. The page is written accordingly, which is why it talks about specifying rather than buying.
Press send and it comes straight to Hilary. Nothing is sent until you do.
