Carpet Underlays Buying Guide

Carpets accumulate both dust and moisture fast while on the floor. And if left unclean, it could turn into a health hazard. For this reason, every home needs a cordless vacuumcarpet cleaner, and handheld steam cleaner to get rid of the accumulated dust and debris.

But a carpet underlay can protect your carpet for an extended period. Although most home projects demand using a hammer drill and safety boots, a carpet underlay is straightforward in its installation. We will guide you through choosing the best carpet overlay.

Benefits of having a carpet underlay

We have seen that having a carpet underway lengthens the life of your best carpet to make it durable and save the cost of replacing your carpet. The underlay for carpets is placed directly on the floor and carefully tacked in with your carpet to provide protection for the carpet from moisture and also to complement it.

Living in areas where noise is an issue, having carpet underlay in lounge of bedrooms helps reduce the distance the noise reaches. Aside from this, the carpet underlay offers a soft and comfortable feeling as you step as well as adding style to your room.

Factors to consider when buying a carpet underlay

Carpet Underlays Buying Guide

Carpet underlays come in different styles, thicknesses and for different purposes. The first thing we recommend to put in mind when buying this carpet underlay is comfort. Getting the right carpet underlay for your floor and sits well with your carpet provides the comfort when you walk.  Another thing to take into consideration is the floor type of your house.

There are different carpet underlay types to select depending on the kind of floor you have. For example, there are the carpet tile underlays, underlay for laminate flooring etc.

Our advice – the thicker the carpet underlay, the better for soundproofing. Take that factor into account. Having the right underlay with the right amount of thickness can help a great deal in curbing noise pollution in the neighboring houses to a minimum.

For warmth, our advice is to search the material the carpet underlay is made of. Felt carpets tend to retain a great amount of heat, followed by the insulated carpets.

Carpet Underlays Buying FAQs

Q: Is the carpet underlay durable?

A: Yes and no. The material used in making the underlay determines the durability of the carpet underlay. The felt carpet underlays tend to last longer than the foam counterparts and are good for your carpet and underlay surface.

Q: Are all the underlay for carpets moisture resistant?

A: Not all of them but some. The materials used in making theses underlays are different and hence have different water absorption capabilities. The felt carpets are the worst to use in damp for they absorb water while the plastic PU foam ones have moisture resisting properties.
