Introduction To Phenotherm® :

Phenolic Foam Insulation

Who We Are?

Bakelite Hylam Limited is a company set up in 1947 to manufacture thermosetting

Plastics in India. Since then the product range of Bakelite supported by its strong R & D

grew manifold. Bakelite Hylam now manufactures Decorative and Industrial Laminates,

Resins and Varnishes, Textured wall covering material, paints, and Phenotherm®

Phenolic Foam. The manufacturing facilities are spread over three plants employing at

total of 500 employees Bakelite Hylam believes in delivering value to its customers by

consistent adherence to standards and continuous product development and quality

improvement. In 1982 Bakelite Hylam Limited was the first and the only manufacturer

who introduced Phenolic Foam Insulation – Phenotherm® in India, made on a modern

continuous foaming plant imported from Europe. Under insulation material we also

manufacture rigid Polyisocyanurate Foam (PIR), Polyurethane Foam (PUF) in form of

slabs as well as pipe section for cold as well as hot insulation.

Why Building Insulation?

Insulation of building is necessary for various reasons. Some of the

Important functions of thermal insulation are:

• Energy conservation

• Fire protection against accidents

• Control of temperature and heat transfer

• Resource Sustainability

Thermal insulation is used as a barrier between two bodies to reduce the

heat ingress into cooler body. By reducing the quantum of heat transfer and by

reducing the air volume of enclosure (e.g. false ceiling). In addition to economy, the

insulation system also helps in preventing condensation, a normal phenomenon

associated with surfaces at temperatures lower than the dew point

What is Phenotherm®?

Phenotherm® Phenolic foam is a rigid cellular foam insulation

material with following properties:

• Fire Resistant

• Not easily ignitable

• No smoke in case of Fire

• Extremely Low Thermal Conductivity

• Excellent Self extinguishing properties

• Negligible smoke generation, less than 5% obscuration

• Very Low water absorption, keeping humidity under control

• Corrosion & chemical resistant

• Emits zero toxic gases

• Does not disintegrate while burning keeping low local temp

•Does not nourish mould growth

•Immune to vermin and insect attack

• Prefabricated wall panels

• Underdeck Insulation

• False Ceiling

• Partition Cavity

• Overdeck Insulation

• Cavity Flooring

• Duct Insulation

• Chilled/Hot Water Pipes

• Vessel Insulations

• Hull Insulations in Ships

Various Phenotherm®

Application

•Significant CO2 savings can be achieved compared to other insulation materials

•Phenolic foam is available in both CFC and HCFC free forms

The reasons for this excellent performance are:

• Phenolic foam has a low water vapour permeance and is therefore highly resistant to

the passage of water vapour

• Phenolic foam has low water absorption which takes place predominantly in the

cut/broken surface cells of the foam

•Phenolic foam is non-wicking. This means that if water enters the insulation system

due to the vapour barrier becoming punctured, any moisture ingress is limited and

confined to the punctured area. This ensures moisture

does not build up and compromise the

whole system

ENVIRONMENT

Phenolic foams have an excellent strength/density relationship being lightweight

but strong. Higher density phenolic foams are typically used for:

• Pipe supports

• Duct supports

• Steel faced composite panels

(including walk-on ceilings)

Mechanical Properties of Phenotherm are:

• BS 4370 Part 2 (KN/M2)

• Compressive Strength – 170 to 250

• Shear Strength - 100 to 110

• Tensile Strength – 250 to 280

Phenolic foam has been used successfully in structural applications for over 24

years.

STRUCTURAL STRENGTH

Phenolic foams offer a range of thermal conductivity performance. The closed cell type

offers the lowest thermal conductivity available from any insulation material resulting

from:

• Closed cell structure of greater than 82%

• Extremely small cell diameter

• Low thermal conductivity gas permanently encapsulated in cells

Phenolic foam offers the following benefits:

• λ values from 0.016W/m-K depending on national certification requirements

• Excellent low thermal conductivity allows reduction in long term energy costs

• Phenolic foam can be up 50% more thermally efficient than other common insulation

materials

• Higher thermal efficiency allows reduced insulation thicknesses to be used thereby

saving valuable space

THERMAL PERFORMANCE

Using G.I Powder Coated False

Ceiling Grid

1. Fabricate and fix 6mm MS Rods,

suspended at specified intervals

with necessary ‘J’ bolts and nuts

etc. The suspender shall be

treated with a coat of Red Oxide

2. Fabricate and fix Aluminium

framework in specified (2’x2 or

4’x2’) grid at specified height

from the floor. The Aluminium

framework shall consist of:

• Wall Angles : 25x25x1.5mm

• Main Tees : 35x25x1.5mm

• Cross Tees: 25x25x1.5mm

Tees will be jointed with necessary

cleats, etc.

3. Place Phenotherm® board of

610mm x 610mm or 1220mm x

610mm size within the

Aluminium grid work and put

pressure clips/nails on top of

Phenotherm® boards to keep the

board in position
