# Mannington ADURA Rigid 7x48

> Mannington ADURA Rigid 7x48: wear layer, locking system, warranty exclusions and installation limits, each with the document it was read from.

Source: https://flooringcompared.com/spc/mannington-adura-rigid-7x48
Coverage: 9 of 9 installation limits declared, 5 of 6 specification claims declared.

Mannington’s ADURA Rigid is a SPC (solid polymer core) rigid core plank measuring 7 by 48 inches at 5.5 mm overall. Everything on this page is Mannington’s own declaration about it, read from documents Mannington publishes, and reproduced next to the document each figure came from.

The row is the product line, not a color. Mannington publishes one specification per line and per plank size, and the color underneath changes none of the figures below, so this page covers every color offered at 7 × 48 in.

This manufacturer's own terms do not permit their photograph to be reproduced here, so none was selected and none was looked for.

## Durability

The wear layer is 20 mil, or 0.508 mm. That is the clear film above the printed layer, and not the thickness figure: this plank is 5.5 mm overall and 1 mm is the backing bonded to its underside.

The wear layer is reinforced, and the maker names the treatment: urethane with ScratchResist and Microban antimicrobial protection. What the coating consists of is not published, so the name stands as a claim and not as a measured property.

There is no abrasion result. Mannington declares no ASTM D4060 cycle count for this product, so the only laboratory check on the wear layer figure is absent. See [wear layer depth](/notes/wear-layer-depth).

## Joint and pad

The locking system is not named. It is declared as click floating angle/angle (no system named), which tells you how it goes down but not whose mechanism it is. An angle-angle joint at least rules out the drop-lock action installers warn about. See [locking systems, named and unnamed](/notes/locking-systems-named-and-unnamed).

A pad is bonded to the underside at the factory. That rules out a second underlayment beneath it. See [attached pad material](/notes/attached-pad-material).

## Warranty

The residential term is published as a word, not a number: a lifetime warranty. No document read for it turns that into a number.

Labor is covered, but conditionally: professionally installed floors only; a floor the owner laid is covered for material and not for labor. See [lifetime warranties and labor](/notes/lifetime-warranty-and-labor).

The remedy does not decline over the term; it is replacement or refund throughout, at the maker's option.

10 exclusions are named in the warranty, and they are listed in full below, not summarized. Among them are the everyday sort a household does not expect to be excluded: rubber or PVC backed mats; sunlight and UV fading; castors and rolling loads; and two others in the list below. The grouping is this reference's; the wording below is the maker's.

## Installation constraints

The floor may run 50 linear feet before a transition is required. Converted for comparison against makers who declare the limit the other way round, that is about 2,500 square feet, but only if the field is square. A long narrow room reaches the linear bound first. See [how far a floor runs before a transition](/notes/max-span-before-a-transition).

A 0.25 in gap is required, and the reading recorded for this cell names what it is measured to: vertical objects and surfaces.

The subfloor limit is declared as 85% relative humidity, and the test named for it is ASTM F2170. A calcium chloride limit of 8 lb is also declared, under ASTM F1869; the two are separate tests of different volumes of the slab and neither substitutes for the other.

No acclimation is required, which is the practical difference between this and a wood floor. The material can be laid the day it arrives. The reading records a condition on that: not specifically required; the maker still recommends installing close to the intended service temperature.

Over radiant heat the floor surface may not exceed 85 °F (29.4 °C). That is a surface temperature, not a thermostat setting. What the figure does not carry is a consequence: radiant heat is not among the warranty exclusions read for this product, so it stands as an installation requirement, not as a stated ground for refusing a claim.

The reading gives a service temperature band of 55 to 100 °F. It is the clause that catches holiday homes and unheated rooms. Whether leaving the band costs the cover is a separate question, and the exclusions are below. A three-season room is permitted; the permission is stated without a separate band of its own.

## Specification claims

Read the two fire figures together before quoting either. Mannington declares Class 1 and, on the same sheet, a critical radiant flux of 0.045 W/cm². ASTM E648 puts Class I at 0.45 W/cm² and above and Class II at 0.22 and above, so the number printed here does not reach the class printed beside it. It falls below both. Both are reproduced as published. Deciding which one Mannington meant is not a call to make here, and a specification that turns on the answer should ask Mannington for the test report.

The coefficient of friction is published as 0.6 with no test method attached. ANSI A326.3 wet DCOF, ASTM D2047 dry static COF and the withdrawn ASTM C1028 produce different numbers from the same floor, so a figure without its method cannot be checked against a threshold that names one. It is printed here because Mannington printed it, and marked as unmethodded for the same reason.

The acoustic figures belong to an assembly, not to the plank: IIC 68 and STC 62 were measured on 6 in concrete slab with drop ceiling. See [impact ratings and assemblies](/notes/impact-ratings-and-assemblies).

The static load limit is 750 psi with no indentation depth beside it. ASTM F970 reports a load against a residual indentation, and makers publish the pair at different depths. So this figure is comparable to another 750 psi only if both were read at the same depth, and what is published here does not establish that.

## How much of this row is filled

Of the 9 core installation limits this reference tracks, Mannington declares all 9, and enough for the installation coverage badge.

Of the 6 core standardized test results this reference tracks, Mannington declares 5, and enough for the specification badge. The other 1 is a result it states nothing about.

12 fields are recorded as undeclared instead of left blank: Approved adhesives, Certifications, Core thickness, Abrasion cycles, Slip test condition, Slip test method, EPD / HPD, F970 indentation, among others. Each of those is the maker publishing nothing, not a failure to look here.

This reference is compiled and published by **the operator of this site**, a materials-only flooring retailer in the United States. It sells the category it describes here. No brand pays for inclusion and no brand is ranked; no figure attributed to a manufacturer is the operator’s own measurement, and each is reproduced with the document it came from. The counts and coverage figures are this reference’s own arithmetic over those declarations.

The operator sells flooring materials. It does not sell or arrange fitting, and this site publishes no labor figures and no offers.
