1) Excellent fire performance

The insulation layer is made of phenolic foam and combined with other materials for building insulation, which can basically reach the national fire protection standard B1 level, which fundamentally eliminates the possibility of external insulation fire. The use temperature range is -250&#;&#;+150&#;.

2) Outstanding effect of heat preservation and energy saving

Phenolic insulation board has good thermal insulation performance, and its thermal conductivity is about 0.023W/(m·k), which is far lower than the commonly used inorganic and organic exterior wall insulation products on the market, and can achieve higher energy-saving effects.

3) Lightweight and non-absorbent

Phenolic insulation board is light in weight, and its bulk density is generally 30-80Kg/m³. At the same time, the phenolic insulation board does not absorb water and is not afraid of rain.

4) Safety and environmental protection

Phenolic insulation board is an environmentally friendly and green product, will not irritate the skin, will not cause any harm to the human body, and emit no toxic smoke during combustion (under limited conditions, it will release formaldehyde, carbon monoxide, etc. beyond the combustion limit).

5) Good dimensional stability

Phenolic insulation board has very good dimensional stability, no matter what the environment, there will be no shrinkage, deformation, etc.

6) Wide range of uses

Phenolic insulation board can not only be used in the external insulation system of building exterior walls, but also can be used in mobile rooms, purification workshops, cold storage color steel sandwich panels, air-conditioning ducts, pipe insulation, curtain wall insulation, roof insulation, computer room cabinet insulation, equipment Thermal insulation, carbon crystal electric heating plate thermal insulation and various fields that require thermal insulation.

 

Application

The thermal conductivity of phenolic foam is about 0.023 (about 1/2 of that of polystyrene, and the heat transfer coefficient of polyphenyl is about 0.042), the fire rating is non-combustible B (which can withstand high temperatures of 150°C), and the price is similar to that of polyurethane. Both polystyrene foam and polyurethane foam are flammable and not resistant to high temperatures, and are being restricted by the fire department. Phenolic fire insulation board can effectively solve the problem of building fire protection and insulation. Phenolic insulation board does not melt, soften, emit low smoke at high temperatures, does not diffuse flame, is resistant to flame penetration, has excellent fire performance, and has good thermal insulation and energy saving effects , Combines excellent fire resistance and good energy-saving effects, and is suitable for external thermal insulation of external walls. Application form of phenolic insulation board:

1) External thermal insulation of building exterior walls (thin plastering system, integrated thermal insulation and decoration, curtain wall system)

2) Central air-conditioning composite air duct insulation (steel surface phenolic composite air duct, double-sided aluminum foil phenolic composite air duct)

3) Color steel sandwich panel field (movable board room, purification project, clean workshop, cold storage, cabinet room, etc.)

4) Roof insulation (residential roof, factory roof, roof insulation brick)

5) Insulation of cryogenic and cryogenic pipelines (LNG pipelines, liquefied natural gas pipelines, cold and hot water pipelines)

6) Various other fields requiring heat insulation

Phenolic foam materials have been greatly developed since the s. They were first valued by the British and American military, used in aerospace, national defense and military industries, and then used in civil aircraft, ships, stations, oil wells and other places with strict fire protection requirements. Gradually promote it to high-rise buildings, hospitals, sports facilities and other fields.

 

Construction method

Insulation of the inner and outer walls of the phenolic insulation board generally adopts the mortar bonding method or the sticking nail bonding method

1. From the bottom to the top, start from the supporting part, and paste the phenolic insulation board on the wall with polymer cement mortar. The bonding area should be greater than 35%, and the first layer should be greater than 50%. If the outer sheath is heavier, 4-6 insulation nails should be nailed per square meter.

2. After bonding, stop for 24 hours before proceeding with the protective layer construction.

3. The external surface construction can be carried out after 24 hours.

4. The thickness and density of the insulation board are in accordance with the design requirements. Generally, it should not be less than 4cm in the area north of the Yellow River, and the density should be 50kg/m. It should be thickened in cold areas. The composite thermal insulation decorative board integrates building thermal insulation and decoration.

1. Factory production. The phenolic insulation board is firmly bonded to the decorative panel.

2. Adopt the light steel keel construction plan, hang the composite thermal insulation decorative board on the keel and fix it.

3. Be sure to handle the gaps between the boards to prevent water leakage.

The non-transparent curtain wall can be bonded to the inner panel of the curtain wall or fixed to the wall surface by bonding. A closed space is formed between the curtain wall panel.

The fire isolation belt shall be combined with nails according to the design requirements, and the distance shall not be less than 30 cm.

Special attention: Newly produced phenolic boards generally need to be post-cured for 21 days before they can be used.

           

           

Which Wall Insulation Type Should I Use and What Problems Exist?

The first step to choosing the right type of wall insulation is to identify what kind of walls you have in your home. There are two main categories of walls: cavity walls and solid walls.

But not all walls are the same, and not all types of insulation are suitable for every wall . Depending on the age, design, and construction of your home, you may have different types of walls that require different insulation solutions. In this article, we will explain the main types of walls, the pros and cons of various insulation options, and the issues you may encounter when installing wall insulation.

Wall insulation is one of the most effective ways to improve the energy efficiency and comfort of your home . It can reduce heat loss in winter and heat gain in summer, lowering your heating and cooling bills. It can also help to prevent condensation, dampness, and mould growth, which can affect your health and the structural integrity of your home.

Cavity Walls

Cavity walls are made up of two layers of brick or blockwork, with a gap or cavity between them. They are common in homes built after the s. The cavity acts as a barrier to prevent moisture from penetrating the inner wall, but it also allows heat to escape easily.

Cavity wall insulation fills the gap between the two layers of the wall with an insulating material, such as mineral wool, polystyrene beads, or foam. This reduces heat loss and improves thermal performance. Cavity wall insulation can be installed by drilling small holes in the outer wall and injecting or blowing the insulation material into the cavity.

The advantages of cavity wall insulation are:

• It is relatively easy and quick to install, with minimal disruption to your home.
• It is usually cheaper than other types of wall insulation.
• It can save you up to £150 per year on your energy bills.
• It can reduce carbon dioxide emissions by up to 610 kg per year.

The disadvantages of cavity wall insulation are:

• It may not be suitable for some types of cavity walls, such as those that are exposed to driving rain, have narrow or uneven cavities, or have damp or damaged bricks or mortar.
• It may require a professional survey and installation by a certified installer.
• It may cause problems with ventilation, drainage, or electrical wiring if not done properly.
• It may reduce the sound insulation of your walls.

Solid Walls

Solid walls are made up of a single layer of brick, stone, concrete, or timber. They are common in homes built before the s. They have no cavity to fill with insulation, so they need to be insulated either from the inside or the outside.

Internal wall insulation involves attaching insulating boards or rolls to the inner surface of the wall or building a stud wall filled with insulation material. This creates a warm and cosy interior, but it also reduces the floor space and changes the appearance of your rooms. Internal wall insulation can be done by yourself or by a professional installer.

Issues with Wall Insulation

Installing wall insulation can bring many benefits to your home, but it can also pose some challenges and risks. Here are some of the common issues you may encounter when insulating your walls:

Planning Permission and Building Regulations

Depending on the type and location of your wall insulation, you may need to obtain planning permission and comply with building regulations. This is especially true for external wall insulation, as it can alter the appearance and dimensions of your home. You may also need to consult with your neighbours, landlord, or conservation officer if your home is in a listed building or a conservation area.

Planning permission and building regulations are designed to ensure that your wall insulation is safe, durable, and compatible with the character and environment of your home. They may also require you to meet certain standards of energy efficiency, fire safety, ventilation, and drainage. You should always check with your local authority before starting any wall insulation project.

Cost and Payback Period

The cost of wall insulation depends on many factors, such as the type and size of your walls, the type and amount of insulation material, the method and quality of installation, and the availability of grants or subsidies. The payback period is the time it takes for you to recoup the cost of wall insulation through energy savings.

The cost and payback period of wall insulation vary widely depending on your specific situation. Generally speaking, cavity wall insulation is the cheapest and quickest to pay back, followed by internal wall insulation and external wall insulation. However, you should also consider other factors, such as the comfort, health, and environmental benefits of wall insulation.

Performance and Durability

The performance and durability of wall insulation depend on the quality of the material, installation, and maintenance. Poorly installed or maintained wall insulation can reduce its effectiveness and lifespan. Some of the common problems that can affect the performance and durability of wall insulation are:

• Thermal bridging: This occurs when heat escapes through gaps or cracks in the insulation layer or through structural elements that have lower thermal resistance than the insulation material. Thermal bridging can reduce the R-value of the insulation and cause cold spots on the wall surface.
• Moisture: This occurs when water vapour or liquid water penetrates or accumulates in the insulation layer or on the wall surface. Moisture can reduce the R-value of the insulation, cause mould growth, rotting, corrosion, or structural damage, and create health hazards.
• Air leakage: This occurs when air flows through gaps or cracks in the insulation layer or around windows, doors, pipes, or wires. Air leakage can reduce the R-value of the insulation, increase heat loss or gain, and cause draughts or noise.

To prevent or minimize these problems, you should choose the right type of insulation for your walls, follow the manufacturer&#;s instructions and best practices for installation, seal all air leaks and gaps around the insulation layer, provide adequate ventilation and drainage for moisture control, and inspect and repair any damage or deterioration regularly.
