ᐅ What is the best way to install Billy shelves when room temperatures fluctuate?

Hello everyone,

I am currently facing the following issue: I want to assemble IKEA Billy bookshelves, but I am dealing with fluctuating room temperatures. Maybe some of you can relate: in summer, temperatures rise above 30 degrees Celsius (86°F), and in winter, they sometimes drop below 5 degrees Celsius (41°F) – along with variations in humidity.

My question is how to optimize the assembly of the Billy bookshelves so that they remain stable despite these temperature and humidity changes, and so that no unsightly warping or material stress occurs in the wooden components.

Are there any specific tips for pre-drilling, screwing techniques, or leveling that should be considered? Also, it would be helpful to know if it’s better to wait for certain temperatures or to apply particular protective measures to the wooden parts.

Thanks in advance for your suggestions!

Hey, great question! 🙂

Especially with wood or particleboard—like with Billy shelves—it’s important not to tighten the parts too much, so they can “move” naturally. My recommendation is: don’t over-tighten screws; keep them a bit flexible.

Generally, it’s best to assemble at moderate temperatures, for example, not right after a heatwave or cold snap. If it’s too hot or very cold, the wood can develop tension.

One more tip: store the shelves for a few days in the room where they will be used before assembling. This way, they can adjust to the environment 🙂

Good luck with building!

To stabilize the Billy shelves when dealing with changing room temperatures, I recommend the following procedure:

1. Preparing the parts: Before assembly, store the shelf components at the installation site for at least 48 hours to allow them to acclimate.

2. Inserting screws: If necessary, pre-drill the factory-made screw holes with a smaller drill bit to avoid putting too much tension on the material, especially in cooler conditions.

3. Tightening screws: Screws should be securely fastened but not over-tightened. Over-tightening can damage the material and cause stress.

4. Aligning: During assembly, ensure proper vertical alignment; softer materials like particleboard are more sensitive to deformation.

5. Consider the indoor climate: Avoid assembling on excessively heated or very humid days, as engineered wood products can react to these conditions.

In summary: Optimal assembly takes into account material acclimation, careful screwing, and environmental conditions.

Should I also provide information about specific tools or assembly aids?

That makes sense, thanks! I was worried that it might be better to store them in a climate-controlled room rather than directly in the area with fluctuating room temperatures.

That matches well.

Is there a general rule of thumb regarding drill bit diameter in relation to the screw size to avoid stress damage when pre-drilling? And would it be better to use a cordless drill with adjustable torque?

IKEA’s instructions are often quite general. I really want to avoid stressing the material unnecessarily because I have little room for correction afterward.

Drill a hole about 80% of the screw diameter.

Set the torque on the cordless drill to a low level.

Pre-drilling is always better than forcing the screw.

Store as already recommended.

That’s all you need.
