Best fireproof roof coatings for your building

Due to the increasing number of wildfires and overheating of the earth, the choices for roof coatings that are fireproof or fire-resistant have become more, overtime.

fireproof roof coatings

It is crucial that the roof coatings materials used in apartments are non-combustible or prevent the spread of flames to other floors of the building. Also very important that the roof material used in apartments is non-combustible or prevent the spread of flames to other floors of the building. Therefore, these fireproof coatings whether they are roof or ceiling so that residents have more time to escape to other floors and exit sections.

If you are also one of those that want to know what the best roof materials are for fireproof coatings, this guide is for you.

 

What are the properties of good fireproof coatings?

What are the properties of good fireproof coatings?

Almost every one wishes to have a wildfire resistant home. These roof coatings which do not catch fire under severe exposures are called excellent fireproof materials or class A fire rating.  When roof materials last the longest before igniting, they are the most effective coverings you want to choose for your building. They should also not spread the flame but prevent it from spreading around.

 

Best fire-resistant roof materials

Best fire-resistant roof materials

You may wonder what the most fire resistant roofing materials are. Here are some coatings that are fireproof enough to keep your roof from burning flames:

Slate

slate

Slate roofing is one of the best natural fireproof coatings. It is a metamorphic rock or a volcanic clay material used as the best fire-resistant covering for roof constructions. Rock is an excellent fire-retardant material and does not burn. In fire rating they are class a roofs. However, besides being great fireproof materials, they are among heavy and expensive roof coatings which need special skill to be installed. Yet some homeowners might not like heavy roof tiles. But they can last more than 50 years especially if they make a fireproof roof structure.

 

 

Clay

Clay

Clay tiles are lighter than concrete roof coatings and are rated as grade A in fireproof roofing. Clays are proved to have the lowest flame spread rate among most fire-resistant materials. Although they are heavy, but can last more than 50 years – just like slate roofing. When it comes to endure heat, clay and concrete tiles can withstand lot better in extreme weather temperature than asphalt shingles or metal roofs.

 

 

 

 

 

Concrete

 

Concrete

Concrete coatings are one of the best choices to be uses as a fireproof roof. They are 40% heavier than clay tiles and a better fire-resistant material. Mostly made of cement, water, sand, concrete tile is a non-combustible material that falls under grade A rate of best fireproof coatings. Beside all of that they are one of the most affordable fireproof coatings exist for a typical roof.

 

UPVC

UPVC

As you know UPVC windows are naturally flame retardant. Now UPVC roof coatings are made from the exact material of those durable and fireproof material. They do not catch fire and by no means accelerate the spread of flames. UPVC stands for Unplasticized Polyvinyl Chloride which is a rigid form of PVC roof sheets. UPVC fire-resistant coatings can stand lightning strikes and heat above 80 °C. Even if it catches fire in wildfire, does not spread and extend the flames. It plays as an extinguisher by cutting the supply of oxygen.

 

 

Asphalt shingles

Asphalt shingles

Not all asphalt shingles are fireproof roof coatings. Some are classified in grade A and some in grade B. Asphalt shingles are petroleum-based which can catch fire in certain circumstances but they are reinforced with fireproof underlayment. Although they are considered cheap coatings among fire-resistant roof materials but they may need to be replaced sooner than expected.

 

 

 

 

 

 

Different classes/grades of roof coatings in fire rating

Based on European classification standards ranks, roof coatings are in 7 classes of fireproofing: A1, A2, B, C, D, E, F. We mention here the most important levels which are the first three class.

 

Grade A

While A1 is a non-combustible material, A2 has some small contribution to fire. A1 rating does not catch fire at any stage – even in wildfire. A2 fire class has a good fire resistance characteristics and the hours it can withstand fire is a little less than A1. Clay, concrete, slate and UPVC roofs are some examples of class A fire rating.

 

Grade B

In grade B fireproof roof coatings will be less than a 60 minutes penetration of fire. They can withstand moderate fire exposure very well. In concise class B roof coatings can only be safe in moderate fire situations. Some shakes and shingles are included in this class fire rating.

 

Grade C

Grade C roof coatings can only be fireproof within limited time and with light fire. Fire resistant roof coatings in class C have a fire spread rate of 76 to 200. Class C fire rating should not be used for structures which fire exposure plays an important role like commercial buildings, electrical rooms, etc. Examples of class C roofs can be plywood and some wood shakes.

 

 

What are the best fire-resistant materials in drop ceilings?

What are the best fire-resistant materials in drop ceilings?

There is a difference made in the structures of fireproof false ceilings – compared to ordinary ones. Common false ceilings are made of wood chips and plaster. These materials lower the roof’s resistance to fire. That is why, in fireproof false ceilings they replace them usually with mineral fibers. Because they show higher resistance to heat and fire.

Gypsum boards, mineral fibers, uPVC and glass are some of the best coatings for a fireproof suspended ceiling.

 

Can fire retardant roof materials have any disadvantages?

 

How to choose the best roof coatings that is fireproof and antiUV?

In addition to all their positive features, the roofs of the opposite side usually have some disadvantages as well.

Cons of fireproof roof coatings

Perhaps, it can be said that the most important disadvantages of fire-retardant roofs is their higher price. In addition to that, we can also add how to install and how much longer the process of construction takes. Of course, there is always a compromise. For example, people who previously complained about the heaviness or installation process of slate roofing, now choose it because it is one of the best fireproof roof coatings. In general, there would be more positive aspects in terms of buying a fireproof coatings for your roof than having none.

UPVC coatings at Sepidfam Varna Company do not need any sealing or insulation and last for about 50 years. Under DIN 4102 fire test German standards, it is confirmed to be A2 fire rated roofing and cladding material with cheaper price – compared to metal, shingles, clays, etc.

Our 2 to 5 millimeter UPVC roof and wall coatings are fireproof and can be used for businesses and buildings sensitive to fire. Having oxygen index of 35%, these fireproof uPVC products have proved to be a self-extinguishing and safe coverings for almost any structures.

The vicat softening temperature test in our UPVC products are 81 °C. That means up until this degree it can keep its stability and shape – which shows it can handle very high temperature and harsh weather, very well.
