What’s the CORE Problem in Restrooms?

core_problem

There are many choices when choosing a material for your bathroom partitions. Before making a decision take a closer look at whats inside!

Material Options

The five main material options when choosing a bathroom partition are; Plastic laminate, Phenolic (black core), Stainless Steel, Baked Enamel, and Solid Plastic. All of these material choices vary in cost and have different cost of ownership models.

My Core is What?

Plastic laminate partitions are made from particle board and finished in a plastic laminate surface.

Phenolic (black core) partitions are compression molded; made from many layers of decorate papers which are saturated with phenolic resin. This forms the base which is then laminated with heat.

Stainless Steel partitions are generally manufacturered with a honey comb or wood core glued under pressure to #304 stainless steel sheets and assembled with roll formed molding.

Powder coated steel or baked enamel is a hybrid epoxy / polyester powder coated finished over galvanized steel is fabricated with roll formed molding and a honeycomb or woodcore.

Solid plastic is made from a polymer composed from extruded resin and is solid throughout.

How Cores Affect You

A source of potentially harmful air quality issues occur with exposure to mold, mildew and fungus.

Veneer exterior, particle board and honeycomb cardboard cores are at high risk for moisture penetration. This risk increases dramatically when these materials are placed in damp and wet environments such as shower rooms and restrooms.

Laminated or hollow core materials cannot be installed without penetrating the veneer exterior, exposing the interior to moisture and potentially water. This can create a harmful condition whereby the core of the partition becomes exposed to moisture while the thin veneer remains seemingly intact. As the core begins to mold and deteriorate, the integrity of both the air quality and partition structure are compromised.

This could result in an unforeseen hazardous and costly mold problem. This is particularly true in rooms with increased humidity such as showers, restrooms and locker rooms

Utilizing solid surfacing materials such as HDPE contributes to better indoor air quality as the solid, non-porous property of these materials resist the growth of mold and mildew.

What is the latest styles in commercial restrooms?  Upscale restrooms that contain high-end materials, commercial bathrooms that feel more like home, and design influences that match the environment around them are three trends you can expect.
Added sophistication – The words luxurious and sophisticated are rarely associated with public restrooms, until now. High end materials such as granite and stainless steel are making their way from the kitchen into the bathroom. This trend is not limited to residential applications. Hotels and other high end facilities are looking for ways to add that same level of sophistication to their public bathrooms. Materials like granite and stainless steel, or surfaces that look like granite and stainless, provide that luxurious feel they are looking for. Check out our designer, mosaic and metallic color series combined with our contour or rotary brushed textures and REGAL™ hinge to add some luxury and sophistication to your next bathroom project.

 

There’s no place like home – There is no place like your own private bathroom when it comes to “nature calling.” But, let’s face it, when you have to go, you have to go, even when you are far from home. A recent trend is creating a spa-like bathroom at home complete with a garden tub, massaging shower and soft lighting. Similar elements can make commercial restrooms feel more like home. In addition to using high-end materials, designers are replacing bright, fluorescent light fixtures with softer incandescent down lighting to create that spa-like atmosphere. They are also incorporating privacy features such as taller doors and privacy hinges. Try our zero sight continuous brackets, hinges and strikes to add privacy to your next restroom project.

 

Common theme all around – Designers are taking elements from the building’s interior design or the surrounding environment and carrying it into the restroom. This goes beyond the simple themed bathroom that pays homage to an era, famous person or pop culture icon. Examples include the public restroom in Bryant Park, New York that mimics the design of the nearby New York Public Library, the restrooms at Santa Monica Pier, California (pictured) that feature an undulating roof evoking thoughts of a vintage wooden roller coaster or the nearby ocean waves, or the bathroom at The Muse Hotel, New York that allows visitors to choose if they are feeling envious, passionate, glamorous, rebellious, macho or vain. What they all have in common is a uniqueness that is personal. To add uniqueness to your next project, ask for our custom embossing – perfect for a school mascot, company logo, or any other personalized detail.

Clean Room Case Study Using Kemlite Glasbord FRP

FRP Terminology

ABS (Acrylonitrile-Butadiene-Styrene) – A group of tough, rigid thermoplastics derived from the reaction of
acrylonitrile, styrene, and butadiene gas. These materials are polymerized together in a variety of ratios to
produce ABS resins.

Accelerator – A highly active oxidizing material suspended in a liquid carrier used to accelerate the
decomposition of peroxide catalysts into highly reactive free radicals. These free radicals react readily with
polymer and monomer molecules to cure a thermoset resin. Examples are diethylaniline, dimethylaniline,
cobalt naphthanate, and cobalt octoate. A cleaning fluid used to remove uncured plastic resin from brushes
and clothing.

Air-Inhibited Resin – A resin in which surface cure will be inhibited or stopped by the presence of air.

BMC (Bulk Molding Compound) – A combination of resin paste and chopped glass combined with a “sigma”
blade mixer under conditions of very high mechanical “working” stress. The compound is delivered to the
press in the form of a ball, slab or an extruded log and dropped into the bottom of a mold; the material is
flowed outward until it assumes the shape of the mold.

Catalyst – A substance (usually a peroxide) which readily forms free-radicals. These free radicals react with
polymer and monomer molecules to speed up the curing of thermoset resins. Catalyst content can vary from
0.2% to 2.0% with higher catalyst levels giving faster cure times. Examples are methyl ethyl ketone peroxide
and benzoyl peroxide.

Color Pigments – Ground coloring materials supported in a thick liquid. Added to the resin, they give it color.

Crazing – Hairline cracks either within or on the surface of a laminate, caused by stresses generated during
cure, removal from a mold, impact or flexing.

Crosslinking – Chain-reaction polymerization which results in chemical links (bonds) between individual
polymer chains. This occurs in all thermosetting resins. Styrene monomer and methyl methacrylate monomer
are the most common crosslinking agents used in polyester resins.

Cure – The total crosslinking or polymerization of resin molecules which permanently alters the properties of
the resin changing it from a liquid to a solid.

Cure Time – The time required for the liquid resin to reach a cured or fully polymerized state after the catalyst
has been added.

Delamination – Failure of internal bending between layers of the laminate.

Dimensional Stability – Ability to retain constant shape and size under various environmental conditions,
such as temperature and humidity.

End – As applied to fibrous reinforcements, a bundle of essentially parallel (i.e., entwined) fibers, usually
glass.

Exotherm Curve – A graph of temperature plotted against time during the curing cycle. Peak exotherm is the
highest temperature reached during the curing reaction.

Exothermic Heat – Heat given off during a polymerization reaction by the chemical ingredients as they react
and the resin cures.

FBVF (Fiberglass Backed Vacuum Forming) – Combining a thermoformed thermoplastic sheet with a
fiberglass mat or roving using the spray-up or hand lay-up process.

Filament – A single, hair-like fiber of glass characterized by extreme length, which permits its use in yarn with
little or no twist and usually without the required spinning operation.

Fill or Sanding Resin – A general purpose polyester resin used to soak and fill reinforcing material in the
initial lay-up of a surfacing application; usually contains wax.

Fillers – Any one of a number of inexpensive substances which are added to plastic resins to extend volume,
improve properties and lower the cost of the article being produced. Examples are calcium carbonate, alumina
trihydrate, feldspar, and calcium sulfate.

Fire Retardancy – Reduction in the ability of a plastic to ignite and burn. This is accomplished by using
compounds (resins or additives) that contain halogens (bromine or chlorine) or phosphorous. Usually alumina
trihydrate filler is also used because of its ability to release water when exposed to high heat.

Foams, Urethane – Polyurethane resins are produced by reacting diisocyanates with polyols to form polymers
having free isocyanate groups. These groups, under the influence of heat or certain catalysts, will react with
each other, or with water, glycols, etc., to form a foam.

Foams, Flexible – A thermoplastic urethane foam which is adaptable and often used for cushioning in the
furniture and automotive industries.

Foams, Rigid – A thermoset urethane foam which has a higher density, higher modulus, and harder surface
than flexible urethane foams.

Gel – A partial cure of plastic resins; a semi-solid, jelly-like state similar to gelatin in consistency.

Gelcoat – A thin surface coat, either colored or clear, of non-reinforced plastic resin. It is occasionally used for
decorative purposes but also provides a protective coating for the underlying laminate.
Gel Time – Time required to change a flowable liquid resin into a non-flowing gel.

HDPE (High Density Polyethylene) – A thermoplastic material composed of polymers of ethylene. It has
relatively high rigidity and can be modified, e.g. with isoprene, to have high impact strength.

Hand Lay-Up – The oldest and simplest molding technique in which reinforcing materials and catalyzed resin
are laid into or over a mold by hand. These materials are then compressed with a roller to eliminate entrapped
air.

Hardener – See catalyst.

Inhibitor – A substance that retards polymerization, thus extending the shelf life of polymers and monomers.
Also used to extend the gel time and cure time of a thermoset resin.

Laminate – A material composed of successive layers of resin and fiberglass bonded together.

Lamination – The compilation of layers of glass matte and resin, and eventual bonding of these layers
together.

Fiberglass Mat – A flat, coarse fabric composed of glass fibers. There are three types: chopped-strand mat,
continuous strand mat, and surfacing veil.

Monomer – A single molecule capable of polymerizing.

Non-Air-Inhibited Resin – A polyester resin using phthalic anhydride as the starting point. A surfacing agent
is added to exclude air from the surface of the resin.

Orthophthalic Resin – A polyester resin using phthalic anhydride as the starting point. Most thermoset
polyester resins use two types of anhydrides in their production: phthalic anhydride and maleic anhydride. A
higher percentage of phthalic anhydride yields a less reactive resin.

PE (Polyethylene) – A thermoplastic material composed of polymers from ethylene. It is normally a
translucent, tough, waxy solid which is unaffected by water or by a large range of chemicals.

PVC (Polyvinyl Chloride) – A thermoplastic material composed of copolymers of vinyl chloride. A colorless
solid resistant to water, concentrated acids and alkalis.

Polyester Resin – The term generally used for unsaturated polyesters. Formed by the reaction of a dibasic
organic acid or anhydride and a polyhydric alcohol to form a series of ester linkages.

Polymer – The end product, usually a solid, produced from monomers.

Porosity – The formation of undesirable clusters of air bubbles in the surface or body of the laminate.

Pot Life – The length of time that a catalyzed resin remains workable.

Preform Fiber – Glass formed over a screen shaped like the mold in which the preform will be used. It
eliminates the need for over-lapping or mitering the corners in molding. Used primarily to form deep draws or
complex parts.

Prepreg – Glass roving or cloth loaded with B-stage resin, catalyst, and pigment ready for placement in a
mold.

Promoter – See accelerator.

Release Agent – A lubricant, often wax, is used to prevent the adhesion of the molded part to the mold. An
internal lubricant such as zinc stearate is used in high temperature molding to obtain release where wax would
melt or be absorbed.

Resin – A liquid plastic substance used as a matrix for glass fibers. It is cured by crosslinking.

Roving – Continuous strands of glass fibers which are grouped together and wound on a tube like untwisted
yarn.

Shelf Life – The length of time a non-catalyzed resin maintains specified working properties while stored in a
tightly sealed opaque container.

Sizing – The treatment applied to the glass fiber to allow the plastic resins to flow freely around and bond to
them.

SMC (Sheet Molding Compound) – An integrated, ready-to-mold fiberglass reinforced polyester material. The compound is composed of a filled thermosetting resin and a chopped or continuous strand reinforcement.  The primary use is in matched die molding.

Spray-Up – Covers a number of techniques in which a spray gun is used to simultaneously deposit fiberglass
and catalyzed resin on a mold.

Stage (of Resin) – The condition of a partially cured resin polymer when it is only partially soluble in monomer
or acetone but still plastic and still heat fusible.

Staple Fiber – A glass fiber of short length formed by blowing molten glass through holes.

Styrene Monomer – A water-thin liquid monomer used to thin polyester resins and act as the crosslinking
agent.

Substrate – Any material which provides a support surface for other materials.

Tack – The stickiness of an adhesive measurable as the force required to separate an adherent from it by
viscous or plastic flow of the adhesion.

Thermoplastic – A plastic material that can be readily softened and reformed by heating and be re-hardened
by cooling.

Thermoset – A plastic material that will undergo or has undergone a chemical reaction caused by heat,
catalyst, ultraviolet light, etc., leading to the formation of a solid. Once it becomes a solid, it cannot be
reformed.

Thickeners – Material added to the resin to thicken it so that it will not flow as readily.

Thinners – Material added to plastic resins to thin it. They may also be crosslinking agents.

Thixotropic – The property of becoming a gel at rest, but liquefying again on agitation.

Viscosity – A measure of the resistance of liquid to flow.

Wet-out –The ability of a resin to saturate fiberglass reinforcement.

Yarn – A twisted strand or strands of glass fibers which can be woven, braided, served, and processed.
