Frequently Asked Questions

Do I need transitions between rooms?

It depends on the flooring type, subfloor, layout size, doorway width, height changes, and manufacturer requirements.

What transition do I need for different flooring heights?

A reducer is often used for height changes, but the correct profile depends on the materials and the product system.

Are stair noses counted as transitions?

They are related trim pieces, but stair noses are usually estimated separately from flat doorway transitions.
