Dseal Aerostar at a glance
The essentials specifiers and contractors ask first — answered straight from the product data, with links to go deeper.
What is it?
Dseal Aerostar is a wall-to-wall expansion joint cover built around a lock profile that mechanically retains the cover over the joint gap, presenting a clean, continuous architectural line. It is made from ASTM 6063 T6 aluminium.
Where is it used?
It is used on interior and exterior wall-to-wall expansion joints in commercial and institutional buildings — corridors, hospitals, campuses, hotels and facades — where the cover must stay securely seated in high-traffic locations.
Why use it?
The lock profile keeps the cover firmly seated as the joint moves, reducing the risk of dislodgement on busy walls, while the aluminium body gives a slim, durable architectural finish across the joint line.
How is it applied?
The aluminium frame members are fixed to each side of the joint over a clean, sound, true substrate, then the cover is engaged into the lock profile so it is mechanically retained across the gap and free to accommodate wall movement.
Key advantages
- Lock profile mechanically retains the cover so it stays seated during wall movement
- Reduces the risk of cover dislodgement on high-traffic and public-facing walls
- Clean, continuous architectural line suits visible interior and exterior locations

About Dseal Aerostar
A plain-language overview of what Dseal Aerostar is, the problem it solves and how Space Arc Engineering positions it in a specification.
Dseal Aerostar is a wall-to-wall expansion joint cover system designed to bridge the structural movement gap between two adjacent wall sections while presenting a single, clean finished line. Expansion joints are deliberately built into walls and facades so that thermal movement, drying shrinkage and minor structural settlement can occur without cracking the surrounding masonry, plaster or cladding. Aerostar is the visible cover-and-frame assembly that closes that gap architecturally and protects the joint edges, without restraining the movement the joint exists to allow.
What distinguishes Aerostar within the Dseal wall range is its lock profile. Rather than relying on a simple snap-in or screwed-down cover, the system uses a mechanical lock detail that engages the cover into the side frames so it stays firmly seated as the joint opens and closes. This matters most on corridors, public circulation walls and other high-traffic interiors where covers are prone to being knocked, leaned on or worked loose over time. The result is a cover that holds its line and resists dislodgement in service.
As a distributor that both supplies and installs Dseal systems, Space Arc Engineering positions Aerostar for projects where appearance and cover security both matter on wall and facade joints. It is manufactured in India from ASTM 6063 T6 aluminium and is part of Dseal's Wall, Roof and Seismic Systems range, alongside floor and parking covers that address horizontal joints separately.
The technical insight
Why Dseal Aerostar behaves the way it does — the mechanism behind the performance, in specifier-friendly terms.
Aerostar is an extruded aluminium assembly: two side frame members anchored to the substrate on either side of the joint, and a cover profile that spans the gap. The defining feature is the lock detail — interlocking extruded geometry that captures the cover into the frames mechanically. As the building moves and the joint gap widens or narrows, the cover is carried by the frames and remains engaged by the lock, so it neither pops out nor rattles loose. This is a purely mechanical movement-accommodation principle; the aluminium itself does not flex appreciably, so the system relies on the frame-and-cover geometry to absorb the relative displacement of the two wall sides.
The choice of ASTM 6063 T6 aluminium is deliberate. The 6063 alloy is the standard architectural extrusion grade — it extrudes into clean, fine profiles and forms a naturally protective oxide layer, while the T6 temper gives it the strength to hold a slim, dimensionally stable section. That corrosion resistance is what allows the same profile family to be used on both interior walls and exposed exterior facade and cladding joints. Aerostar is a cover-and-retention system only: it is not, by itself, a fire or acoustic barrier, and where the joint must also be rated for fire or sound, separate compatible barrier accessories are installed within the joint behind the cover.

Limitations & considerations
Where Dseal Aerostar is not the right answer. Check these constraints from the manufacturer before specifying — using it outside its scope is the most common cause of failure.
- Not a fire or acoustic barrier on its own — fire-rated or sound-rated joints require separate compatible barrier accessories installed within the joint
- It is a wall (vertical) cover system, not a floor or parking cover; horizontal trafficked joints need the appropriate Dseal floor system instead
- Performance depends on correct frame anchorage to a sound, true substrate — weak or out-of-plane wall edges will compromise retention and line
- Movement capacity, profile sizes and joint-width range are configured per project and must be confirmed against the manufacturer's data for the specific application
- As a metal cover, it provides no waterproofing by itself; exterior joints needing a water seal require an appropriate gasket or membrane detail behind the cover
Selection & best practice
How to decide whether Dseal Aerostar fits your job — and how to apply it so the repair lasts.
Specify Aerostar for wall-to-wall expansion joints where the cover sits in view and must stay securely in place — corridors, lobbies, healthcare and institutional walls, and exterior facades. Choose it over a basic snap-on or screw-fixed wall cover when traffic, public access or aesthetics make cover security a priority, since the lock profile is its key differentiator. For floor, parking or seismic-rated horizontal joints, or where the joint must carry a fire or acoustic rating, pair it with the correct Dseal system or barrier accessory rather than relying on the wall cover alone.
Application best practice
- Confirm the actual joint width and expected movement against the project drawings, and select the profile size accordingly before ordering
- Fix the side frame members to a clean, sound, true substrate; make good any weak or uneven wall edges first so the cover seats correctly
- Set the frames parallel and at a consistent gauge across the joint length so the cover line stays straight and the lock engages fully
- Engage the cover fully into the lock profile along its length and verify it is retained before final finishing
- Where the joint also requires fire, acoustic or water protection, install the appropriate compatible barrier accessory within the joint behind the cover
- Coordinate continuity at wall-to-floor and wall-to-ceiling transitions so the joint cover system runs without gaps at changes of plane

Frequently asked questions
Common questions about specifying and sourcing Dseal Aerostar.
What is Dseal Aerostar?
Aerostar is a wall-to-wall expansion joint cover from Dseal, built around a lock profile that mechanically retains the cover over the joint gap while presenting a clean architectural line. It is made from ASTM 6063 T6 aluminium for both interior and exterior walls.
What does the lock profile do?
The lock profile is interlocking extruded geometry that captures the cover into the side frames. It keeps the cover firmly seated as the joint moves, which reduces the risk of the cover being dislodged in high-traffic areas — its main advantage over simple snap-on or screw-fixed covers.
What material is Aerostar made from?
Aerostar is made from ASTM 6063 T6 aluminium, the standard architectural extrusion grade. It is corrosion-resistant and dimensionally stable, which is why the same profile suits both interior walls and exposed exterior facades.
Can Aerostar be used on exterior walls?
Yes. The ASTM 6063 T6 aluminium construction is corrosion-resistant, so Aerostar is suited to exterior facade and cladding wall joints as well as interior walls. For exterior joints that need a water seal, an appropriate gasket or membrane detail is added behind the cover.
Is Aerostar a fire or acoustic barrier?
No. On its own Aerostar is a cover-and-retention system, not a fire or sound barrier. Where the joint must be fire-rated or acoustically rated, a separate compatible barrier accessory is installed within the joint behind the cover.
Can Aerostar be used on floors or parking decks?
No. Aerostar is a wall (vertical) joint cover. Horizontal trafficked joints in floors, parking decks or seismic floor applications should use the appropriate Dseal floor or seismic system, which is engineered for load and traffic.
What joint widths and movement can Aerostar handle?
Profile sizes are configured to the project's joint width and expected movement, so the exact range is selected per application. Space Arc Engineering can provide the relevant technical data sheet and help match the right profile to your joint.
