ᐅ Door Between House and Garage: Secondary Entrance Door as a Fire-Rated Door?

Hello!

We are building our garage directly attached to the house – at least that’s the plan for later; for now, it’s just the house.

Our front door will have a triple locking system with an automatic lock (RC1). All the windows are also RC1 rated.

The door to the garage is currently just a standard steel fire door with a standard lock and single locking mechanism. Because of this, I wanted a proper side entrance door with the same lock as the front door.

However, it seems such a door is not available as a fire door.

1) Is a fire door or a smoke-tight door (T30) really necessary there?
2) Does anyone know of T30 doors with a solid (at least triple) locking system (automatic lock installable) and an acceptable U-value?

Exactly. Without these two options at the secondary entrance door.

I have now received feedback from our general contractor. The connection to the garage does not need to be a T30/T90 fire door; a standard side entrance door is sufficient.

Happy Bavaria, but better double-check this information yourself!

You need to consider whether that is sufficient for you.

For example, if your car catches fire in the garage, a secondary entrance door might not offer much protection.

And if a burglar enters your garage, they can take their time trying to open the door. No one would see them...

Fire Protection:
Yes, I would definitely recommend installing interconnected smoke detectors.

Burglary:
That’s exactly why we want the secondary entrance door, because it is also available with a three-point locking system and automatic locking.
This means the door locks itself automatically when it closes.
I think it’s unrealistic to expect that the door is always locked manually with a key.

For the thousand euros that an automatic upgrade costs, I would rather install electronic monitoring – it might be easier.

At the front, we also have a motorized lock, but the T30 door remains a simple door.
