Hi, slowly but surely (let’s hope), our house construction is coming to an end.
The contract actually states that due to the residual moisture in the roof rafters, the attic should not be developed for 1 year.
However, the roofer said that the wood was technically dried and should no longer have any moisture.
Anyway, we agreed with the construction manager that we may build a "path" at least 1-2 meters (3-6 feet) wide to at least partially use the attic as a cellar substitute!
According to the contract:
- Mineral wool insulation is installed between the wooden structure (which really can cause itching).
- A thermally insulated staircase will be installed.
- For houses with attics, the attic spaces used for storage must be designed for a load capacity according to the structural calculations of at least 100 kg/m² (20.5 lb/ft²).
So, I think you have the most important information.
What would you recommend now? OSB boards (if they even fit through the stair opening) or rather tongue and groove boards?
It is basically only supposed to serve as a cellar substitute.
The spacing on the floor between two rafters is 96 cm (38 inches) from center to center, and the rafter itself is 8 cm (3 inches) wide.
I have 10 “gaps” to fill (each spaced 96 cm / 38 inches apart).
In the middle of the attic, lengthwise, there is a wooden beam crossing, which is 4.5 cm (1.75 inches) higher than the other smaller rafters.
The distance between this middle beam and the inner exterior wall (or rather the rafter in front of it) is 213 cm (84 inches).
Now, the pictures for better understanding.

Under OSB boards, you might consider counter battens for ventilation, but even then their effectiveness is debated. In my opinion, OSB is generally unsuitable.
Also, I wouldn’t choose the lowest grade wood. Higher quality boards are easier to install, and later you can even walk on them with socks without worrying about getting splinters in your feet.
Have the boards cut to length right away, so you won’t have to do much sawing later. For example, for 3m (10 feet) boards: 3 × 95cm (37 inches) – 1 = 284cm (112 inches).

Hi, one more question.
What should I do with this annoying 4.5cm (1.8 inches) thick beam that runs lengthwise right in the middle of the attic space?
Even if I use 28mm (1 1/8 inches) tongue-and-groove boards, this beam is still 1.7cm (0.67 inches) higher and would definitely be a stubbed toe waiting to happen.
When installing, should I lay all the boards parallel and always end them on one of the joists, or stagger them like a floor? And then let some boards end “in mid-air”?
Also, have a 3m (9.8 feet) board cut into 3 pieces at 95 minus 1 cm each? What is this minus 1 about?
