Engineered timber can be installed in apartments, but most Australian strata buildings require flooring to meet minimum acoustic ratings under National Construction Code (NCC) guidelines. The right acoustic underlay under engineered timber can bring an installation into compliance with common strata by-law requirements. Before purchasing, confirm your building’s specific acoustic requirements with the strata manager. Your Floorworld team can then recommend an appropriate product and underlay combination to meet those specifications.

Many hybrid flooring products come with an underlay layer pre-attached to the back of each board. If your chosen product includes this, you generally do not need to add a separate underlay, though a moisture barrier may still be required over concrete slabs. If the product does not include an integrated underlay, adding one improves acoustic performance and helps compensate for minor subfloor irregularities. Your Floorworld team will confirm what is required for the specific product you choose and your subfloor situation.

Yes, underlay is important for laminate flooring. It provides a moisture barrier above the subfloor, improves acoustic performance between floors, adds comfort underfoot and helps the floor tolerate minor irregularities in the subfloor surface. Some laminate products come with an underlay layer pre-attached to the boards. If your chosen product does not include one, selecting an appropriate underlay for your subfloor type is an important part of the installation. Your Floorworld team can advise on what suits your specific product and situation.

Carpet underlay is a cushioning layer installed between the subfloor and the carpet. It improves comfort underfoot, adds thermal insulation, reduces noise transfer between floors, protects the carpet backing from abrasion, and extends the carpet’s working life significantly. A good underlay makes even a mid-range carpet feel premium. The difference between walking on carpet with good underlay and the same carpet with poor underlay is immediately apparent, which is why your Floorworld team considers underlay selection as important as the carpet itself.

Yes, absolutely. Underlay makes a real and immediate difference to how carpet feels, sounds and performs. It softens the surface underfoot, reduces impact noise travelling to rooms below, adds thermal insulation and absorbs the daily stress on the carpet backing that would otherwise cause it to wear faster. The difference is most obvious in the feel: the same carpet installed on good underlay feels noticeably more comfortable and luxurious than the same carpet installed on cheap or worn underlay.

Yes, thicker underlay improves the thermal insulation of a carpeted room, helping it retain warmth, particularly when the floor is over a concrete slab or in a cooler climate. Dunlop ComfortCare 10mm underlay carries an R0.24 thermal value rating. In Victoria, Tasmania and the NSW Highlands, where winter temperatures are significant, a thicker, denser underlay can make a noticeable difference to how warm and comfortable a carpeted room feels through the colder months.

For most residential bedrooms and living areas, a 10mm rebonded foam underlay is the standard recommendation and a good balance of comfort, acoustic performance and cost. A 12mm underlay adds more cushioning and is a popular upgrade for master bedrooms where the premium feel underfoot is worth the additional investment. For stairs and some commercial applications, a firmer, thinner underlay is generally more appropriate, as excessive thickness under stairs can cause the carpet to loosen over time with foot traffic.

Many hybrid flooring products come with an integrated underlay pre-bonded to the back of each board. If your product includes this, a separate underlay is generally not needed, though a vapour barrier over concrete may still be required. If your hybrid or laminate product does not include integrated underlay, adding an appropriate hard-flooring underlay improves acoustic performance and helps compensate for minor subfloor irregularities. Your Floorworld team can confirm exactly what is needed for the specific product you choose.

For apartments and upper-floor rooms, acoustic performance is the most critical underlay specification. The goal is to reduce impact sound travelling through the floor to the room below. Dunlop ComfortCare has a 26dB acoustic reduction rating and is a well-regarded choice for apartment and multi-storey installations. Many Australian strata buildings have specific acoustic requirements under NCC guidelines. An appropriate acoustic underlay can help bring an installation into compliance. Check your building’s by-laws with the strata manager before choosing your floor and underlay combination.

Dunlop ComfortCare and Dunlop Springtred carpet underlays are made from rebonded polyurethane foam, a dense, durable material produced by compressing and bonding recycled foam. This construction gives it excellent acoustic dampening, thermal insulation and long-term cushioning properties under carpet. Dunlop also offers Timbermate, a polyethylene foam underlay for hard flooring products including laminate, hybrid and engineered timber. Both ranges are available through Floorworld stores.

Dunlop ComfortCare is a carpet underlay: a 10mm rebonded polyurethane foam with a 26dB acoustic rating, R0.24 thermal value and antimicrobial protection. It is designed to go under carpet and is not suitable for hard flooring. Dunlop Timbermate is a hard-flooring underlay made from polyethylene foam with a built-in moisture barrier. It is designed for use under laminate, hybrid and engineered timber floors. Using the wrong underlay for the wrong product type can affect performance and may void the product warranty.

For every roll of Dunlop ComfortCare Underlay sold, five dollars is donated to the Pancare Foundation, which supports Australians living with upper gastrointestinal cancers and funds research into treatment and early detection. This makes ComfortCare a popular choice for customers who want their purchase to contribute to something meaningful alongside its practical performance. Ask your Floorworld store for more details about the donation program.

Airstep is an established Australian underlay brand with a solid reputation for comfort and performance under carpet. It is a practical choice for everyday residential installations across a range of room types. Availability varies by store and region. Your nearest Floorworld store can confirm current Airstep stock, compare it against other underlay options available for your specific carpet and subfloor type, and help you choose the most appropriate product.

SmartDrop Acoustic is Kenbrock’s flagship vinyl plank product, a 5mm thick modular plank that was one of the first thick-format vinyl planks introduced to the Australian market. It features enhanced acoustic properties that reduce impact sound and a realistic timber-look surface finish. Kenbrock was also the first flooring brand in Australia to use phthalate-free plasticiser across its entire range, which is relevant for households focused on indoor air quality and low-VOC materials.

Yes, particularly for a master bedroom or any bedroom where comfort underfoot is the priority. The difference between 8mm and 12mm underlay is immediately apparent when you walk on the carpet. Thicker underlay also adds thermal insulation, which matters in Victoria, Tasmania and the colder parts of regional Australia where bedroom comfort through winter is important. For guest bedrooms or children’s rooms, a standard 10mm underlay is generally sufficient. For the master bedroom, the upgrade to 12mm is worth the relatively modest additional cost.

Yes, particularly for carpet. Underlay makes a significant difference to how carpet feels underfoot in a bedroom, its acoustic performance and how long it lasts. A 10mm or 12mm rebonded foam underlay adds cushioning that is immediately apparent to anyone walking into the room. For hard floating floors in bedrooms, underlay improves acoustic performance between floors and compensates for minor subfloor irregularities. Underlay is not an optional extra: it is a fundamental part of how the final floor performs.

Carpet fibres absorb sound energy within the room, which reduces echo, softens keyboard and footstep noise and prevents sound from reflecting off hard surfaces during calls. Hard flooring in an enclosed home office acts as a reflective surface: sound bounces off it and creates the echo that makes voices sound less clear on calls. A carpet or a large rug in a hard-floored office achieves a similar acoustic improvement and is a simple, cost-effective solution if you do not want to change the flooring entirely.

Yes. Using an incorrect underlay, or installing flooring without the recommended underlay, can affect your product warranty. Some manufacturers specify which underlay products must be used to maintain full warranty coverage. Dunlop ComfortCare underlay, for example, carries a lifetime carpet warranty when used with eligible carpet products. Always confirm underlay requirements with your Floorworld team as part of the selection process, not after installation.
