The ThermalSafe® insulated metal panel meets the required ratings required for today’s buildings through Intertek and UL fire approval, in both US and Canada. These panels are UL fire rated assemblies that achieve one-, two- or three-hour fire ratings for walls and 1.5 hours for ceilings.

What is fire rated cladding?

PVC/uPVC or vinyl cladding products usually have a fire rating of C or D, which means this type of cladding is combustible. For comparison, most untreated wood cladding products have a fire rating of D. uPVC is composed of two building blocks, chlorine and ethylene from natural gas or petroleum.

Is cladding fire-resistant?

As a minimum, most external wall cladding would possess a classification of ‘surface spread of flame’ which helps to suppress the spread of fire, however only fire rated cladding can offer the higher classifications of limited combustibility or non-combustibility.

What is fire-resistant wall board?

Fire-rated gypsum board is a form of drywall that helps prevent the spread of flames across a home or business. When gypsum drywall is exposed to fire, the water is slowly released as steam, effectively slowing heat transmission. This gypsum is used to develop fire-resistant drywall.

What is class 3 flame rating?

between 76 and 200
What is a Class C or Class 3 fire rating? A Class C or Class 3 fire rating has a flame spread rating between 76 and 200. This rating incorporates building materials like plywood, fiberboard, and hardboard siding panels. It also includes any of the faster burning whole woods.

What does a B2 fire rating mean?

normal flammability
The valid norm is differentiated into two fire protection classes. ‘A’ stands for non-flammable and ‘B’ for flammable materials. B2 = normal flammability. B3 = high flammability.

Which cladding material is flammable?

Aluminium composite panels (ACPs), as used at Grenfell, containing a polyethylene core can be highly flammable. High-pressure laminate (HPL) cladding, which is also widely used on high-rise buildings, is at least as flammable.

Is Hardiflex cladding fireproof?

James Hardie fibre cement building products achieve the best possibly Early Fire Hazard Properties and, when used in specially designed wall configurations, achieve Fire Resistance Levels of up to two hours.

Is cement board fire rated?

Yes, HardieBacker® 1/4″ Cement Board is deemed noncombustible when tested to ASTM E 136 and can be used in conjunction with other noncombustible materials around a fireplace.

Is all sheetrock fireproof?

Although all drywall is fire resistant to a degree, type-X and type-C drywall are designed specifically to be used in fire-rated assemblies. These products help to contain fire in the area of its origin much better than regular drywall.

What are the fire rated insulated metal wall panels?

Looking for fire rated insulated metal wall panels? MF Fire Rated panels are Kingspan’s mineral fiber panel option, which provide a fire resistive rating of up to three hours. Exterior profile options include Shadowline, Micro-Rib, or Azteco Embossed to meet all performance and design needs.

What are the Fire Classifications of cladding panels?

These cladding panels carry a fire classification result ranging from A1 to D in accordance with European Standards EN-13501-1.

What are MFMF fire rated panels?

MF Fire Rated panels are Kingspan’s mineral fiber panel option, which provide a fire resistive rating of up to three hours. Exterior profile options include Shadowline, Micro-Rib, or Azteco Embossed to meet all performance and design needs. Factory applied sealant is available to help increase the speed of installation.

What is the difference between external cladding types?

Whilst most external cladding types carry a minimum classification of ‘surface spread of flame’ designed to slow and control the spread of fire, only FR (fire rated) cladding provides the higher classifications of either limited combustibility or non-combustibility.
