With the introduction of two brand new slitting machines in March
2009 and December 2011, it has enabled us to be even more
versatile, now being able to supply foam strip in widths from 3mm
up to 1000mm, and thicknesses from 1.5mm right up to 40mm. With
most base materials being held in stock, the vast majority of
requirements can be turned around immediately. Standard thicknesses
of foam strip products we are able to manufacture include 1.5mm,
2mm, 2.5mm, 3mm, 4mm, 5mm, 10mm, 12mm, 15mm, 20mm, 25mm 30mm and
Expanded rubber (solid rubber that has been blown trapping air
bubbles within its cell structure), known more commonly as foam or
sponge is available in strip or coil formats and can give many
advantages including gap filling, air and water sealing, draught
and dust solutions, cushioning, thermal insulation, sound
deadening, water filtration as well as proving excellent
resolutions to both packing and filling problems.
Our foam strip products are available in a wide range of grades,
colours and densities. Low, medium and high density foam strips are
all manufactured by our Company. UL94 VO silicone strip is readily
available for applications in London Underground.
Sponge strip is also available and manufactured in any given
length. Foam strip or coil, by its nature, can either portray an
open cell structure designed for air and water filtration, and
sound and noise reduction purposes or a closed cell structure for
heat insulation and water absorption prevention. What’s more, a
self adhesive backing can be applied to any foam strip product we
Available in almost and given length and width, our foam strip
products can be tailored to suit any application. Our foam strip
products are available in square section, sheet, roll, strip, or
coil formats. Furthermore, any foam based strip product we supply
can have a peel away adhesive backing applied to it in order to aid
in sealing/bonding applications as well as helping in certain
applications as a third had fixing when clamping down onto it. When
an adhesive backing is applied to either foam strip or rubber strip
it becomes more commonly known as foam tape or rubber tape.
Foam and Rubber Strip manufactured sealing tape is based on a
diffusion-open material, which renders high resistance to wind and
weather as well as UV-light, and simultaneously reduces the risk of
rot and fungal attacks on adjacent building materials.
Our sealing tape is a high-quality product, which to a vast extent
benefits the environment, both in production and application.
Applications include the following:- Sealing of gaps between
window/door frame and brickwork, sealing between concrete sections,
sealing between sill and embrasure, sealing of double casement
windows, sealing of sky-lights and roof-lights, sealing of roof
construction, insulation against noise and vibration in connection
with ventilation and climate installation, insulation against noise
and vibration within the caravan and park home industry, insulation
in connection with window installation.
Dependent upon its grade, foam strip, as compared to solid rubber
strip, has the advantage of possessing a little compression,
lending itself to sealing two surfaces and creating a water and air
tight seal. It is a fair assumption that foam strip will compress
to about half of its original thickness under compression, however,
this will obviously depend upon the density of the foam chosen and
the weight load being placed upon it.
Frequently used within the glazing, and construction trades, it
enables sealing to take place through its compression. However,
foam strip is also an excellent solution to thermal and acoustic
problems and due to its cell structure means it is very much a
multifaceted product. Most foam strip is supplied in a black
colour; however certain grades of neoprene, polyethylene and EPDM
are also available in white, blue, and red. Please feel free to ask
a member of our sales team for more information on this.
Grades of foam strip are readily available for any required
application and include medical, food, fire and flame retardant
variants, LSOH, water, UL94 VO, chemical grades and many more.
Please ask one of our sales team members which grade of material is
most suitable for your specific application.
Expanding foam tape is also manufactured by our Company. This
revolutionary product is normally used within the construction
trades where the open cell polyurethane foam strip base material is
pre-compressed until application and fully expands its to gap fill
evenly between wooden window frames.
The main purpose of this product is to allow fresh air to circulate
into the window whilst at the same repel water and driving rain
from entering ultimately irradiating dry rot. It is fair to say
that expanding foam tape expands up to five times its original
compressed state. Expanding foam tape is a pre-compressed sealant
made of impregnated permanently elastic fine cell PU foam which
expands evenly and slowly to provide a seal against wind and
driving rain, draughts, dust and gaps. It is an ideal solution for
sealing against surfaces with irregular patterns expanding to fill
the gap up to its expansion rate. Our rolls of expanding foam tape
come with a self adhesive backing and from widths of 10mm right up
to 1000mm rolls, and thicknesses ranging from 3mm, 5mm, 6mm, 10mm
We often get asked the question as to what is the difference
between EPDM Foam / EPDM Sponge and Neoprene Foam / Neoprene
Sponge. Outlined below are the general reasons as to which material
is best suited to a specific application. Briefly though, closed
cell EPDM foam and closed cell Neoprene foam look very similar to
one another and are both used in a variety of our gaskets and
sealing strips throughout a multitude of industrial sectors.
EPDM foam strips are generally thought as to possessing better
resistance to water and weathering applications, whereas Neoprene
foam is better suited not only to both of these attributes but has
a good resistance to sealing against oil and many petroleum
derivatives and chemicals. Both are a relatively cheap way of
sealing however, Neoprene foam is generally perceived as the
slightly more expensive option compared to EPDM foam. Both
materials portray excellent value for money and have incredible
ageing credentials with neither going brittle over time.
EXPANDED CLOSED CELL NEOPRENE SPONGE / FOAM STRIP
Neoprene Strip – A common closed cell expanded material we supply a
vast majority of our foam strip in is neoprene foam. A general
purpose material, neoprene foam strip has many attributes including
its suitability for weathering. Due to the superb air tight and
water tight characteristics of expanded neoprene foam it is
generally used within the automotive, electronics and construction
trades. It makes it a very good material for jointing expansion,
weather strips, glazing and closure seals as well as shock
absorbers and cushioning. Our foam strip products are also widely
used throughout the vintage car and marine industries.
Neoprene foam strip / Neoprene sponge strip or coil properties also
make it a suitable choice of materials for requirements including
thermal insulation on items such as garage door seals. With a
respectable temperature range of -20 C / +90 C expanded neoprene
strip lends itself as an ideal solution to a multitude of indoor
and outdoor solutions. Neoprene, a trade name for Dupont’s
Polychloroprene is blown and expanded to form an expanded state.
This means it is an excellent choice to be used for any
irregularity that may occur in construction. It is an excellent
choice for gap filling and will not allow anything to pass through
it’s closed cell structure.
Furthermore, due to the extraordinary aging properties of closed
cell neoprene foam it means that the sealing strip role will not
fail over prolonged exposure on a specific application. Neoprene’s
properties make it advisable to use in most requirements where
temperatures and/or oils or greases need to be stopped from
transfering through to a mating surface. Sealing strips commonly
made out of neoprene sponge are extremely durable and with its
slight compression allows the material to be squeezed or moulded
into nearly any gap or vent immediately stopping any inflow of air
or water. Higher grades of neoprene sponge strip are also available
with fire retardant ratings and class O approval.
Our neoprene sponge strips are not only available in cut section,
and are commonly available to buy in sheet or roll formats.
Neoprene foam / neoprene sponge is available to by as neoprene foam
sheet / neoprene sponge sheet or neoprene sponge roll / neoprene
foam roll if required.
Dependent upon grade and density of neoprene foam chosen certain

standard EPDM foam strip range from 1.5mm, 2mm, 3mm, 4mm, 5mm,
6mm,10mm,12mm, 20mm and 25mm.
Due to the fantastic air and water tight characteristics of our
EPDM foam strip / EPDM sponge strip and coil products, it is mainly
used within the automotive, electronic and construction trades. It
is also a very good material for jointing expansion, weather
strips, glazing and closure seals as well as shock absorbers and
cushioning. Available in various grades and densities including
low, medium and high, EPDM foam strip / EPDM sponge strip is a
Furthermore, we are able to offer certain EPDM strip products in a
