# Ambient SPC Rigid Core 7x48

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

Source: https://flooringcompared.com/spc/ambient-spc-rigid-core-7x48
Coverage: 5 of 9 installation limits declared (3 in conflict), 1 of 6 specification claims declared, 6 document conflicts.

Ambient’s SPC Rigid Core Luxury Vinyl is a SPC (65% limestone stone polymer composite) rigid core plank measuring 7.125 by 48 inches at 5 mm overall. Everything on this page is Ambient’s own declaration about it, read from documents Ambient publishes, and reproduced next to the document each figure came from.

The row is the product line, not a color. Ambient 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 7.125 × 48 in.

## 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 mm overall and 1 mm is the backing bonded to its underside.

The wear layer is reinforced, and the maker names the treatment: vinyl. 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. Ambient 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 lock (no system named), which tells you how it goes down but not whose mechanism it is. 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 not covered. The remedy is replacement material or a refund of the purchase price, which is the smaller half of the bill on a floor that has to come up. 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: sunlight and UV fading; and pets. The grouping is this reference's; the wording below is the maker's.

## Where the maker’s documents disagree

Ambient’s own documents do not agree about 6 fields on this product. Nothing is published for them above, because a value two of the maker's documents contradict is not a value to publish under anyone's name. The disagreement is itself a fact about the documents, it is checkable, and it is set out below with both sources named.

The warranty terms are the sharp case: commercial warranty is stated as 15 years in one document and 5 years in another. A buyer comparing this product against another on published warranty length is comparing against a number that depends on which of the maker's PDFs they happened to open.

## Installation constraints

The floor may run 40 linear feet before a transition is required. Converted for comparison against makers who declare the limit the other way round, that is about 1,600 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).

That limit is conditional: it applies to over radiant heat the maker cuts the run to 25 ft in any direction and requires a break at that interval. A limit that holds in one application but not in another cannot be read out of the column alone, and a reader who takes the number without the condition takes the wrong half of the sentence.

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: none is required unless the cartons have been below 40F or above 95F for more than an hour, in which case 12 hours unstacked.

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 60 to 90 °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.

## How much of this row is filled

Of the 9 core installation limits this reference tracks, Ambient declares 5. Of the other 4, 1 is a limit it states nothing about and 3 are limits two of its own documents answer differently, which this release holds back instead of picking between. 2 more declarations would carry the installation coverage badge, so it is neither earned nor refused here. The count beneath it measures the reading done here, not Ambient’s disclosure.

Of the 6 core standardized test results this reference tracks, Ambient declares 1 and states nothing for the other 5, so the specification badge is not earned.

21 fields are recorded as undeclared instead of left blank: Approved adhesives, ASTM product standard, Core thickness, Abrasion cycles, Slip test condition, Slip test method, Slip resistance, E648 class, among others. Each of those is the maker publishing nothing, not a failure to look here.

The opposite gap is recorded too, and this one is ours and not Ambient’s: 1 field in the dictionary has not been read for this product: EPD / HPD. It is missing from the table for want of a document held here, not because Ambient publishes nothing about it.

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.

Page views are counted with Google Analytics, along with how long each page stays in view. There is no filter, no form and no comparison box on this site. Nothing a reader could type into. [What is counted](/about#measurement).
