9/Armstrong DLW Linoleum with
underfloor heating
Armstrong DLW Linoleum is suitable for installing
on substrates above underfloor heating systems
(see the leaflet ”Resilient floorcoverings and
parquet flooring on heated floor constructions“
issued by the Central Association for the German
Building Industry or refer to relevant country stan-
dards).
9.1 Dry constructions
Dry constructions can consist of anhydrous
gypsum or brick plates. The floorcovering can be
installed once the joints have been skimmed over
with a levelling compound.
9.2. Wet constructions
With wet constructions, the heating pipes or cables
are bedded into a floating cement or anhydrous
gypsum screed. Before the floorcovering is
installed, care must be taken to ensure that any
residual moisture generated by the heated ele-
ments is removed. This is generally the responsi-
bility of the heating engineer, who should issue a
report on the required heating-up and cooling-
down measures undertaken. This report replaces
the moisture tests required of the flooring installer,
who may not carry out these tests where there is
underfloor heating systems installed unless the sub-
floor installer has left marked measuring points.

10/ installation of Armstrong DLW
conductive Linoleum
The requirement for floors with a maximum electri-
cal resistance to earth of 1 x 10
8
ohms is fulfilled
by the installation of Armstrong DL
W conductive
Linoleum LCH. The earthing of the conductive
flooring is a matter for an electrical installation
engineer
, who must observe the relevant regu-
lations.
The adhesive used must be homogeneously con-
ductive. This requirement is not generally fulfilled
by light conductive adhesives with fibre additives.
Inquiries about the type of adhesive to be used
and the conduction system which is to be em-
ployed may be obtained direct from the manu-
facturers or from the Armstrong Floor Products
Technical Department, telephone number
01235 554848.
10.1 Installing on copper strips
A continuous copper strip is run under each row
of tiles or sheet of linoleum. These copper strips
are connected via two strips running at right
angles. For the installation of Armstrong DLW
conductive Linoleum LCH, Armstrong offers
copper strips as follows: Supplied as: 50 m rolls.
Amount required: As a rough guide for ordering,
about one 50 m roll is needed for 80 m
2
of floor-
covering or 25 m
2
of tiles. This must be connected
to the main building earth by a qualified electrician.
10.2 Installation on a primed conductive
subfloor
The sub-floor is first primed with a conductive
primer in accordance with the manufacturer’s
instructions for use. A one-metre length of copper
strip is glued to the prescribed earth connection
on the substrate. Please consult the supplier of
the material before using. For installing anti-static
linoleum to other sub-floors contact Armstrong
technical department for specialist advice.
Frequency of earth connection points: At two
points in the room – more in the case of rooms
over 40 m
2
in size. The maximum distance from
an earth connection point may not exceed 10 m.
10.3 Installing in dual requirement areas
Armstrong DLW Linoleum LCH is capable of
efficient discharge of any static electricity
and at
the same time meets the location insulation
requirements as per DIN 57100/VDE 0100 T410.
Because of the overall difficulty, it is basically
recommended to obtain information from the
Armstrong Floor Products Technical Department
on telephone number 01235 554848 (or local
country number).

Cleaning and maintenance
The contractor has to hand over to the client the
written maintenance instructions for the floor-
covering as part of the project handover. The
following printed pamphlets are available free of
charge:
· Cleaning and maintenance recommendations
for Armstrong DLW Linoleum
· Maintenance tips for continuous beautiful floor-
coverings (Domestic users)
Details are available from the Armstrong Floor
Products Technical Department on 01235 554848
(or local country number).
