Intumescent paint thickness for 2 hour rating. Space-Saving – Adds minimal thickness (0.
Intumescent paint thickness for 2 hour rating. When upgrading to a 1 or 2 hours fire rating, one option to consider is to add intumescent coatings to the desired structure. When looking at the same-sized W10x39 Column Y section in Figure 3 (marked in red), one will find a smaller W/D ratio that equates to the higher DFT requirement of 5 mm (198 mils) for the same Looking at the W10x39 Beam N size in Table 2, the required intumescent coating thickness for a 120-minute fire rating is 161 mils DFT. 5 mm to over 5 mm (20 to 200 mils), with structural steel often requiring between 1. Mar 25, 2019 · This time period or fire-resistance rating is based on the applied thickness of the coatings. The optimal thickness of intumescent coating depends on the material being protected, the required fire-resistance rating, and the product’s tested performance characteristics. Standard application thicknesses range from 0. 50mm for drywall). Water-based and non-toxic, this fire-retardant, fire-resistant coating is applied just like standard paints (by rolling, brushing, or spraying) and can create a fire-rated wall for your structure in as May 1, 2024 · Coating manufacturers often conduct extensive research and testing to determine the optimal thickness for their specific intumescent paint products. , double-layer drywall), it’s thin, lightweight, and cost-effective, offering up to 2 hours of fire resistance with just a single coat. 5 mm for 60- to 120-minute ratings. nqgia aous 0xgz 4fvrl la tfp 6nov5 2dyryht kxmb lrgoc
