Frequently Asked Questions (FAQs)
1. Can you use carpet as underlayment?
Can You Use Carpet as Underlay? Using carpet as underlay is not advisable when you are installing new floors. While it will help make your laminate or hardwood feel more comfortable, using carpet instead of underlay may end up causing damage to the floor in the long run.
2. What underlay is needed for carpet tiles?
Do you need underlay for carpet tiles? Carpet tiles come with an underlay attached. This means that in normal circumstances, no additional underlay is required. In noisy rooms or high-footfall commercial areas, acoustic underlay can be a good idea.
3. Do you put carpet padding under carpet tiles?
Padding is not needed on most carpet tiles. There are different sizes, making it easy to fit into tight spaces, and they are lightweight, making it easier to carry around than large rolls of carpet.
4. Can you put carpet over ceramic tile?
Normal ceramic tiles with 1.5 to 3mm grout lines are completely suitable to be carpeted over, provided the flooring is in a decent condition. An important thing to note when considering whether to lay carpet over your tile floor is that you won't be able to use the flooring again.
