The legalization of marijuana has sparked a building boom for grow houses across the country. These can be multi-million dollar builds, but often, fire code is the last thing that people consider. That's where we come in. When you are working with your architect and your fire marshal or building inspector, be sure to bring up this topic early. What often happens is the grow rooms get built, outfitted with lights, misters, fans, etc., plants are growing, and the fire marshal comes in and say …

There are basically two types of fire retardant - intumescents and non-intumescents. Here's the simple explanation. Intumescents swell up when exposed to heat. Non-intumescents don't.More complex explanation.When exposed to flame or heat above around 325°F, intumescent coatings swell up and form a thick layer of char. The heat causes a chemical reaction that generates gas that fills tiny little pockets in the coating - almost like foam. That foam insulates and protects the substrate from th …

When dealing with fire retardants, there are typically two standards - time ratings and class ratings. Class ratings are usually Class A, B or C, with 'A' being the best. This is usually measured with the test for ASTM E84, which measure Flame Spread and Smoke Development. It most often applies to NON-structural building materials, like plywood, fascia, wall coverings, and things like that. Time ratings are usually 1, 2 or 3 hours, and apply to STRUCTURAL things like beams, joists, flo …

Now that schools are beginning to open up, it is time to start thinking about getting your school in line with fire codes. RDR offers fire retardants for most of the typical school requirements - paper and posters on walls, curtains for windows and stages, plastic decorations, holiday decorations, and upholstered furniture. Most often, it involves items that teachers bring in to decorate their classrooms. These all have to be treated to meet NFPA 701. RDR makes it very easy - just give us a call …

SPF (spray polyurethane foam), like most other organic materials, is combustible. Although SPFs are formulated with flame retardants to meet the requirements of various construction codes and minimum performance standards there is still a need to provide further protection from fire. All foams must undergo some common fire tests such as ASTM E84, UL 723 and others, to determine how fast and how far a flame will travel across the surface, along with how much smoke is produced when the foam is exp …
