Fixed Blast Louvres
- Blast Louvres are manufactured to allow the free passage of air throughout buildings.
- This is a bespoke product and can be manufactured to meet customer's required dimensions, blast resistance and wall construction/fixing detail.
- They are built so as not to break apart when subjected to a blast load. If a standard louvre collapsed under a blast load, there would be serious risk of injury to people and damage to property. Blast Louvres are intended to prevent that from happening.
- The louvres can also protect against fragmentation if required; depending on the blast, there may be a chance that fragments.
- Blast louvres are primarily used in commercial and military environments.
Product Description
The product is bespoke and manufactured to withstand a large range of blast pressures. The product is intended to allow the free passage throughout buildings, but in the event of a blast, does not break apart. The Louvres are typically required where machinery and equipment requires continuous air flow but have the potential to cause a blast. The Blast Louvres accomodate this air flow requirements whilst also offering protection in the event of an explosion.
Advantages
The Blast Louvre can also be combined and is compatible with Blast Ducting/Dampers in order to provide a complete package for a project.
Each unit is bespoke and made to order with the required fixing hole positions and fixing details which allows it to be used in conjunction with other non-blast and blast-rated products to provide a holistic solution.
Features
- Available in a factory PPC Finish, Mill Finish and Galvanised.
- Can be used for both internal and external applications, installed into walls, panels and doors.
- Can be installed into recess or face mounted with flange.
Protecting A Diverse Range Of Industries
When it comes to industries that face the threat of internal explosions, the list is surprisingly diverse. Our Fixed Blast Louvres are applicable in various sectors, including the petroleum industry, energy and mining, and even brewery facilities. This wide applicability makes it an essential safety measure across different operational setups.
Automotive plants, co-generation facilities, and lithium battery storage areas also greatly benefit from our Blast Louvres. In environments where safety is paramount, such as hospitals and university laboratories, our vents offer that extra layer of protection that could also be the difference between total collapse and business continuity. This explosion protection helps to mitigate damage to businesses and organisations so that they can get back to operational capacity as quickly as possible.

Fragmentation Protection Option
Protection from fragmentation is also necessary in certain applications. This can include such operations as ammunition manufacturing.
In this instance, the blast louvre will also need to accomodate fragments or shrapnel that can be travelling up to as much as 3,000m/s. In mitigating this resistance, we incorporate our ballistic technology to produce a system that offers both blast resistance, bullet resistance and hence fragmentation resistance.
This product is available in all sizes in galvanised or factory PPC finish. This unit is purpose made as with all of our products. In terms of installation, these units can be reveal or surface mount fix.
They are suitable for both indoor and outdoor applications and work in both directions.

Frequently Asked Questions
What level of blast resistance can you achieve?
We can accomodate a wide range of static and dynamic blast pressures.
Each unit is bespoke and manufactured to the required blast resistance.
Please get in touch with us to discuss your specific project requirements.
Where are Blast Louvres required?
Typically, Blast Louvres are required in Data Centres, Power Plants, Government and Healthcare facilities.
Blast Louvres allow for the free passage of air however following an explosion or blast, does not become a threat itself by breaking apart or becoming a projectile.
What materials are the units constructed of?
The construction of the unit is dependent upon the blast resistance requirement and dimensions of the louvre.
Each unit is bespoke and made to order, taking into account the required blast resistance, location, dimensions and wall construction.
Typically, the units are manufactured from heavily profiled steel and stainless steel.
The units are then have a factory PPC finish as standard, Mill Finish or Galvanised Finish as required.
