What is Fire resistant Insulation or fireproof insulation?

A specially designed material which can resist burning and withstand heat is known as fire-resistant or fireproof insulation material. Fire-resistant insulation material slows the spread of fire and protects the building. Fireproofing is more and more common choice of people nowadays for commercial, domestic and industrial application. Fire-resistant insulation material is specially designed to resist high temperature and ensure no toxic smoke is released if it does encounter flames.

Insulation materials which have limited combustibility or are non-combustible in nature but have insulative properties are known as fireproof insulation. These materials slow down the spread of flame and protect the structure of building providing enough time for people to escape the property in case of fire.

 

Rating of fire resistance insulation

Fire retardant insulation materials are classified in various ratings as follows

  • A1- non-combustible
  • A2- limited combustible
  • B-F - Low- high contribution to fire

The ‘S’ part relates to total ‘Smoke propagation’, in the first ten minutes of exposure to flames.

There is the point of determining a ‘smoke’ index:

  • S1 = a little or no smoke
  • S2 = quite a lot of smoke
  • S3 = significant smoke

The ‘D’ part relates to ‘Flaming droplets’ during the first ten minutes of exposure to flame. 
The indicator to determine flaming droplet is:

  • D0 = no flaming droplets
  • D1 = some or few flaming droplets
  • D2 = quite a lot of flaming droplets
Fire rating of insulation

 

Types of fire-rated insulation materials

  • Mineral wool

Mineral wool is also known as stone wool or rock wool and is an ideal material because it is non-combustible and does not conduct heat at all. This material can resist the temperature above 1000 degree Celsius in event of fire.

  • Fiberglass insulation

Fiberglass insulation naturally have fire resistance properties making it an ideal material to use in high-temperature areas. Fiberglass does not burn but it may melt in temperature exceeding 100 degree Celsius. Fiberglass batts and fireproof insulation rolls have a class 1 fire rating and are non-combustible.

  • Foil & Multifoil insulation

Foil and multifoil insulation materials have excellent fire rating for fire propagation and spread of flame. They are specially designed and tested to the highest standards and is fully certified to use in the United Kingdom.

  • Insulated Boards

Fire Resistant plasterboards utilise various additives and a high-density core to enhance their fireproof qualities. Fireboard or Fire-resistant plasterboard offers better protection against fire when it is compared to other plasterboards. In high fire hazard areas, it is advised by the governing bodies to use Fire insulation boards or fireproof insulation sheets. Fire performance of the house is based on complete systems such as a partition, wall, ceiling membrane or floor, therefore insulated plasterboard cannot be considered on their own in terms of fire protection. Celetox 100mm has rated class 1 in surface spread of fire and rated E in reaction to fire.

  • Expanding foam

Fire-rated expanding foam can provide up to 240 minutes of fire rating and is used as an efficient seal against gas and smoke. Expanding spray foam insulation has grown fast as one of the most popular options over time because of its cost-effectiveness. They comply will all relevant building regulations and can be used on commercial, residential and industrial properties.

Benefits of fireproof insulation material

  • Fire protection
  • Non-combustible
  • No Toxic smoke
  • Lightweight
  • Cost-effective
  • Easy and quick install
  • Provide thermal insulation
  • Acoustic performance

Fire safety and building regulation

Building regulations specify various rules and regulations when it comes to fire safety. They have specified rules for detached houses and even strict rules for attached houses. Fire Safety Approved Document B building regulation in England covering fire safety matters within and around buildings. Building regulation have stated various precautional measures which are to be followed when constructing a new house to protect life and few of the measures are as follows

  • Providing escape routes
  • Preventing or restricting the spread of fire from
  1. To or from neighbouring house
  2. Inside the house
  • Providing access route for fire brigade
