Revit families now available for FyreBox, FyreBox Cast-In and MaxiCollars
Architects and BIM teams can now download Revit families for BOSS FyreBox™, FyreBox™ Cast-In and MaxiCollars.
The families allow BOSS Passive Fire systems to be incorporated directly into the Revit model, helping teams coordinate product selection, service locations and required space earlier in the design process. For FyreBox™ systems, the family also accounts for the required opening, helping improve coordination between architecture, structure and services before construction reaches site.
The files are free to download from each product page and from the new Revit section on our Resources page. A Read Me is included covering family types, parameters and loading.
What is in the release
BOSS FyreBox™ is a fire-rated multi-service transit for large bundled penetrations through walls, slabs and ceiling systems. A vast range of services, including power, data, paircoil, PEX, sprinkler pipes and uPVC, can pass through a single enclosure. The innovative BrushSeal system allows additional services to be installed quickly and easily, future-proofing thebuilding by allowing additional services at any time. The family covers the BFB-150 to BFB-900 range, plus slimline and extra-depth models.
FyreBox™ Cast-In does the same job for new concrete slabs. It goes in before the pour, so there is no core drilling and no retrofit firestopping through a finished slab. The family covers BFBCI-300 to BFBCI-900 and the extension sleeves.
MaxiCollars™ are retrofit fire collars for combustible and lagged pipes through fire-rated walls and floors. Steel casing, intumescent lining, only 30 or 40 mm deep. The family includes all twelve sizes from MC-25 to MC-250.
All three systems are tested to AS 1530.4:2014 and AS 4072.1-2005, with FRLs up to -/240/240 depending on the configuration.
Why passive fire belongs in the Revit model
BOSS FyreBox™ Revit families incorporate actual product dimensions and required annular gaps for compliant retrofit installations and fire-rated mastic application. This helps designersaccurately size penetrations, coordinate services and avoid costly clashes or rework on site.
For FyreBox Cast-In, modelling the transit early allows its location and dimensions to be coordinated before construction, ensuring accurate placement in the formwork and eliminating the need for subsequent core drilling.
Clash detection gets better too. When services run through a defined enclosure, your hydraulic, electrical and mechanical consultants are all working to the same box, and nothing collides with the beam next to it. With MaxiCollars, the family gives you the collar footprint and fixing positions on both sides of the element, so you can check clearances to adjacent penetrations and slab edges before the drawings go out.
Then there is specification. A product and tested system that has been specifically chosen for its FRL and performance specs travel with the drawings. The contractor tenders on it, the certifier expects it, and a last minute swap to an untested imported product gets harder to justify.
How to judge a Revit family library for fire protection
Not all Revit content is equal, and in passive fire the difference shows up on site. A family that looks complete but carries the wrong dimensions or parameters can throw out coordination and weaken the compliance position of the whole assembly. Before you load any fire protection family into a live project, put it through three checks.
Is it verified by the manufacturer?
Only the manufacturer of the fire protection system can confirm that a family matches the current certified product and the tested configuration behind it. Generic content offers no such guarantee. If the product has been revised and the family has not, you are modelling something that can no longer be installed.
Our families were built for BOSS and checked against the current range and the systems tested to AS 1530.4 and AS 4072.1.
Is it well organised?
A good library saves you time instead of costing it. Look for consistent naming, mapped parameters, clear documentation and files you can drop straight in rather than rebuild. If a family’s parameters do not map cleanly to your schedules, you will pay for it later in correction time.
Every BOSS download includes a Read Me covering the family types, the parameters you can edit and how to load the files.
Does it behave in a live model?
Load the family into a project template before it goes anywhere near a live job. Check that it does not bloat the file or drag performance. A family that misbehaves in a live project is worse than one you never downloaded.
Download Revit families direct from the manufacturer
Where a family comes from matters as much as how it looks. Generic online BIM libraries give you breadth, but they often lack the product-specific data and certification detail that fire-rated assemblies depend on. Going manufacturer-direct removes the risk of outdated or non-compliant product data, and it means the content in your model is the system that will actually be installed.
BOSS Passive Fire makes its Revit families free to download from each product page and from the Revit section of our Resources page.
How to use the files
Download the family for each product, then open the Read Me to check the family types, editable parameters and the Revit version the files were built in. Load the family into your project, pick the type that matches the service bundle and place it in the wall or slab.
If the bundle does not fit a standard type, or you are working through a substrate we have not listed, talk to our technical team. Sizing a transit at design stage is a ten-minute conversation. Sizing it on site is a variation.
What comes next
These three families are the start. We are working through the rest of the range, and the fastest way to move a product up the list is to ask for it. Tell us what you need modelled and which project it is for.
