--- title: "Regupol vs Damtec: comparing the complete systems" description: "Compare Regupol and Damtec proposals through the specified floor, test construction, compatibility and installation scope before choosing an underlay." canonical: "https://monkeyfloors.com/acoustic-underlay/regupol-vs-damtec" language: "en-AU" published: "2026-09-25" updated: "2026-09-27" --- [Part of: Acoustic underlay: the layer that deserves a closer look](https://monkeyfloors.com/acoustic-underlay) # Regupol vs Damtec: comparing the complete systems Quick answer If two flooring quotes name Regupol and Damtec, compare the exact systems rather than the brand names. Request the underlay code, floor finish, fixing method and complete acoustic report for each, then check compatibility and relevance to your building. Neither brand name alone establishes a quieter floor or strata approval. By [Monkey Floors editorial team](https://monkeyfloors.com/about) · Published 25 September 2026 · Updated 27 September 2026 · 4 min read ## At a glance Purpose Compare two specified offers First document The complete proposed floor construction Decision basis Relevant evidence, compatibility and installation scope Two quotations can look almost identical until you reach the underlay line. One names Regupol, the other Damtec, and each may present a thickness or acoustic number as the reason to choose it. The useful comparison begins with the exact product and everything installed around it. This guide gives you a worksheet for that discussion. It does not declare a brand-wide winner. ## What should each quotation identify? Ask for a construction that another person could recognise on site: the floor finish, underlay code, thickness, fixing method, preparation and any intermediate layers. A brand name on its own leaves too much unresolved. [ATFA’s acoustic-underlay guidance](https://www.floorchoices.com.au/information-sheets/installation-over-acoustic-underlays/) recommends agreement between the flooring and underlay suppliers on the installation method. Request that confirmation for both proposals. A worksheet for Regupol and Damtec proposals | Check | Record for the Regupol proposal | Record for the Damtec proposal | | --- | --- | --- | | Product identity | Exact code and document version | Exact code and document version | | Floor construction | Finish, layers and fixing method | Finish, layers and fixing method | | Compatibility | Written acceptance of the combined system | Written acceptance of the combined system | | Acoustic evidence | Report, metric and tested construction | Report, metric and tested construction | | Installation scope | Preparation, moisture work, edges and height | Preparation, moisture work, edges and height | | Approval | How the proposal addresses the actual conditions | How the proposal addresses the actual conditions | If a quote uses an older name, a nickname or thickness alone, ask the supplier to identify precisely what will arrive. Do not infer product equivalence from a familiar number. ## Are the acoustic results comparable? Place the complete reports side by side. Check whether each result comes from a laboratory test, an on-site measurement or a prediction. Copy the full acoustic metric rather than only its numerical value. Then compare the finish, substrate, ceiling and fixing method. A report for tiles bonded over a mat is not a direct comparison with a report for floating timber. If the constructions differ, ask the acoustic consultant what conclusions can reasonably be drawn. The [AAAC explanatory note](https://aaac.org.au/resources/Documents/Public/AAAC%20Guideline%20for%20Apartment%20and%20Townhouse%20Acoustic%20Rating%20-%20Explanatory%20Note%20V2.0.pdf) makes the central limitation clear: an isolated product cannot guarantee an acoustic rating. An attractive headline figure does not settle performance in your apartment. Use the [report reader](https://monkeyfloors.com/tools/test-report-reader) to organise the two sets of information. Where the bases or metrics differ, resolve that mismatch before discussing which number looks better. ## Does equal thickness make the products interchangeable? No substitution should be based on that assumption. ATFA notes that equal-thickness underlays can have different properties and performance. Ask the flooring maker to confirm the particular mat proposed for the intended installation. Check the less visible details as well. An adhesive-fixed system needs accepted interfaces, while a floating system needs the support and movement arrangement specified for the board. Record moisture provisions and any separating or supporting layer. If a proposal changes from one mat to another after approval, issue a revised construction for assessment. Keep the accepted change with the order and installer instructions. ## What installation differences could change the decision? Walk each installer through the same room plan. Ask what preparation is included, how the finished floor meets adjacent surfaces and which junctions need special attention. The [ABCB sound handbook](https://www.abcb.gov.au/sites/default/files/resources/2022/Handbook-sound-transmission-insulation-in-buildings.pdf) explains how rigid connections can reduce the benefit of resilient isolation. Ask how the specified perimeter and fixings will be completed rather than judging the mat only across the open floor area. Compare the total finished height. Include preparation, adhesive and any supporting sheet, not just the mat and board. A proposal that leaves a doorway unresolved still needs design work, even if its acoustic evidence is promising. ## How should you compare value? Give each contractor the same scope and ask them to state exclusions. Check whether both quotations include removal, preparation, moisture work, trims, disposal and any required acoustic assessment. If one price is lower, identify what differs before deciding that the underlay caused the saving. Record product substitutions and provisional items in plain language. You need to know what could change once the old floor is lifted. There is no useful universal price comparison without matching work and current quotations. The purpose of the worksheet is to make the offers comparable. ## What makes the final selection ready? Choose after the unresolved points have answers: the proposed system is identified, compatibility is documented, the acoustic evidence has been assessed for the building and the installation scope is clear. In an apartment, keep the written conditions from the approval process alongside the accepted quote. If those conditions require completed-floor testing, agree the arrangements before installation. For the construction details, continue to [timber underlay](https://monkeyfloors.com/acoustic-underlay/timber), [tile underlay](https://monkeyfloors.com/acoustic-underlay/tile) or [rubber, foam and cork](https://monkeyfloors.com/acoustic-underlay/rubber). The relevant material guide should help you resolve the next question in the specification. ## Questions, answered ### Which is better, Regupol or Damtec? There is no brand-wide answer here. Assess the exact underlay and floor construction in each offer, including the acoustic evidence and written compatibility. ### Can I compare two mats with the same thickness? Yes, but equal thickness is only one dimension. Check the permitted finish, fixing method, supporting layers and test construction before comparing acoustic numbers. ### What if a quote names Regupol 4515, Regupol 4080 or Damtec 3 mm? Ask for the exact current product code and supporting documents for the material being supplied. A shorthand name or thickness does not identify every layer or establish that an older report covers the proposed product. ### Can the installer substitute one brand for the other? Request the proposed substitution in writing and reassess compatibility, acoustic evidence, height and any approval conditions before installation. ### How should I compare the quotations? Give both installers the same room plan, finish and acoustic requirement. Check that preparation, adhesive, supporting layers, trims and any required testing are included on the same basis. ## Sources 1.
