Can I use 1/2 inch board if that is what is on site?

Not in a rated assembly. Type X is 5/8 inch because the core needs that mass and reinforcement to hold together under heat. It looks identical once finished and it is not the tested assembly — we check board against the specification.

Do you stand behind your fire-rated work in Tamarack?

Yes. We install to code and walk the Tamarack job with you, and if something is not right we come back and make it right.

My Tamarack garage ceiling has board but the joints are open. Is that a problem?

Usually yes. Untaped joints are one of the most common reasons a garage separation is not complete, because the board looks installed. Often the fix is finishing the joints and sealing penetrations rather than replacing the ceiling.

How do I know which rated assembly my Tamarack project needs?

It comes from your drawings or from the building official at permit stage, not from us and not from the board supplier. We build to the assembly you have been given, and if what is specified does not match what is on site we will tell you before boarding.

Does the rated wall have to go above the ceiling?

Yes. A separation that stops at a suspended ceiling is not a separation — fire and smoke go over it. The wall runs to the structure above and is sealed at both ends. It is the detail most often missed in conversions.

Is Type X the same as fireproof?

No. Type X resists fire for a stated period inside a tested assembly, which buys time to get out. Nothing about it makes a wall fireproof, and the rating only holds if the whole assembly — board, spacing, joints and penetrations — is built as specified.

Rated separations in Tamarack that pass inspection the first time

A fire-rated wall is not a board, it is an assembly. In Tamarack that means the specified board thickness and type, the specified stud and screw spacing, taped joints, and every penetration firestopped. Miss any one of those and the rating is not there, whatever the board says on the back.

Finishing a rated wall in Tamarack without compromising it

Rated first, pretty second

Taping on a rated assembly in Tamarack does two jobs: it completes the fire separation and it produces the surface you will paint. The tape and fill on the rated joints is not optional cosmetic work.

Level of finish

Beyond the rated joint treatment, the visible finish level is your choice — a garage ceiling rarely needs the same finish as a living room. We will tell you where a higher level is worth paying for and where it is not.

Rated ceilings and the membrane above

Protecting the structure

A rated ceiling under living space is protecting the floor structure above it, which is why the board and its fastening are specified rather than optional.

Access hatches

Any hatch through it interrupts the assembly and needs a rated detail. It is a common find in Tamarack garages where storage access was cut in afterwards and never addressed.

Fire-rated garages, suites and party walls in Tamarack

Garage firewalls

The most common fire-rated job in Tamarack is the garage-to-house separation — Type X board on the common wall and ceiling. Code-compliant install and finish.

Legal suites and shared walls

Frequent work in Tamarack homes and multi-unit buildings. We build the rated separations these require. See our legal suite drywall page.

Type X and Type C are not interchangeable

Two different boards

Type X is the common 5/8 inch rated board. Type C carries additional additives that resist shrinkage at high heat and is specified where an assembly — often a ceiling — depends on the board staying in place longer.

Substituting downward fails

Where drawings call for Type C, Type X is not an equivalent, and an inspector who spots it will fail the assembly. We order to the specification on your Tamarack drawings and tell you if what is on site does not match it.

Rated does not mean soundproof

Two different goals

People often assume a fire-rated Tamarack wall is also a sound wall. It is denser than a standard wall so it helps a little, but rating and acoustic performance are separate specifications.

When both are needed

A suite separation usually needs both, and they are built together. If sound is what you actually care about, we would rather design for that explicitly than let a rating imply it.

Coordinating with the electrician early

Boxes in rated walls

Outlet and switch boxes in a rated Tamarack assembly need treatment — spacing rules, pads or listed boxes — and back-to-back boxes are a particular problem.

Why early matters

Rearranging a box after board is up means opening a rated wall. Walking the wall with the electrician before boarding takes ten minutes and avoids that entirely.
