Frequently asked questions

Do I need underlay under laminate?

Yes, unless the planks have it pre-attached. Underlay evens out the subfloor, cuts noise and adds a moisture barrier over concrete.

Which direction should planks run?

Usually parallel to the longest wall or toward the main light source, which hides the joints best.

What do I need to enter into the Laminate Flooring Calculator?

Just 5 values: room length, room width, waste, coverage per pack, price per pack. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.

How does the Laminate Flooring Calculator work out the answer?
