Is decking fire resistant?
Composite materials are generally high in plastic which possess a high heat release rate, meaning the intensity of the heat it gives off is increased and more likely to ignite. In order to reduce this, composite decking manufacturers add fire retardants to the inner decking materials.
Is Trex decking fire rated?
At Trex, we do everything we can to ensure it. Our Transcend and Select decking lines retain a Class B fire rating, while our Enhance decking lines retain a Class C fire rating; however, they are not fireproof.
Is composite decking fire resistant?
Composite Boards Decks are where fires often start, whether from windblown embers or from charcoal falling out of your grill. Most wood species are rated Class C for fire resistance, but you can build safer with a Class A–rated composite decking like AmeraDeck, made from PVC and wood fiber.
How heat resistant is composite decking?
Stays up to 30° Cooler in the Sun Our capped polymer deck boards are made with 100% synthetic material, which is less dense than traditional lumber or decking made from composite material and wood flakes. Less density means boards absorb and retain less heat.
Is AZEK decking fire retardant?
For instance, AZEK is the only product that has a Class A Fire Rating, that means that although the board may burn it’s not going to cause the flame to spread to your house.
Can you fireproof wooden decking?
Flame retardant coating used to protect decking. To avoid flames spreading across decking, urgent fire protection treatment is required, and the most effective solution is the Envirograf® Product 92 (ES/VFR) fire retardant system.
Can you use a fire pit on a Trex deck?
Outdoor fire pits and fireplace use with Trex: Wood burning fire pits are not recommended on top of Trex decking unless using a product called DeckProtect™. Wood burning fire pits can damage the decking due to the extreme heat from the bottom of the fire pit and/or burning embers “shooting” onto the decking.
Is Trex less flammable than wood?
Fire-Resistance Rating Trex decking is classified as a Class C, or Class III, building material. An “A” rating indicates a high level of fire resistance, while a C rating refers to an average level of fire resistance. So if a fire occurs, your Trex lumber will burn just like the wood on any traditional wood deck.
Does all composite decking get hot?
So, does composite decking get hot in direct sunlight? While early composite decks were very sensitive to temperature and did get notoriously hot, any new composite decking will be much more resistant to heat. High-quality modern composite boards don’t become hotter than traditional wooden deck boards.
Does Trex decking get hotter than wood?
While wood gets hot enough to make walking with bare feet uncomfortable, composite decking gets even hotter. In some cases, Trex can become so hot that it may become unusable under intense, direct sunlight. The darker the Trex decking material, the more heat is retained.
What is a Class B fire rating for wood?
A Class B or Class 2 fire rating is the next best rating on the list. The flame spread rating of Class B would fall between 26 and 75. This rating is typical for slower-burning whole wood materials. A whole wood material would be wood planks that are in the same form as they were when they were cut from the tree.
What is a Class 1 fire rating?
A class 1 fire rating is the best fire rating of materials that can be achieved. Class A fire ratings indicate a flame spread rating somewhere between zero and 25. Class A fire ratings indicate a flame spread rating somewhere between zero and 25.
What are fire rated composite decking standards?
The objective of creating fire rated composite decking standards is to try to ensure that a deck would still be intact and show no evidence of flaming or glowing 40 minutes after the burner used during the testing has been turned off. If the material passes this test, it is considered to be a fire-resistant deck material.
What are Class D and Class E fire rated materials?
It also includes any of the faster burning whole woods. Ratings between 201 and 500 would be considered a Class D material, and Class E materials include anything with a flame spread rating above 500. Classes D and E are not considered effective against any form of fire exposure.
