Hello,
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs.
At this time, there is no opportunity for a fire-rated solution for wall-to-curtain wall applications, as the ASTM E standard language is specific to applications between rated floor or floor/ceiling assemblies and exterior curtain wall applications. As such, we rely on the code language to provide Code Evaluation Details (CEDs), which are code compliant solutions but do not carry fire-ratings and thus are subject to AHJ approval. The reason these details cannot achieve a fire-rating is because standard language outlines time and temperature criteria, but code language does not outline either of these. Hilti does not support sealing directly to the glazing for a code compliant solution, so we would recommend terminating at a framing member or curtain wall insulation.
Should you want to proceed with a CED, we can address your application through a Code Evaluation Detail, which will be a custom detail showing your exact application with the firestop components required to be compliant with the specified code language.
Hilti is proud to announce the launch of our engineering website, the HILTI CONSTRUCTION PLATFORM (HCP). This platform will be the home for all of your Fire Protection Engineering needs, including Engineering Judgment requests.

Zhuzao are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.
There are several factors to consider here. The first would be keeping the room sealed off. The more air tight a temperature barrier is, the more effective it will be. This may include using floor sweeps in the bottom of the curtain, Velcro on the side edges, and filler panels with valances on the top. All of these options ensure that there are minimal, if any, gaps in the curtain installation.
The second factor to consider is the air that you are putting into the room. Both the temperature of the conditioned air and the CFM (or the quantity) of the conditioned air pumped into this space will play a high role in how well you can achieve your temperature goals.
This would depend on what product you are looking at. For our thinner curtain options, we tend to fall in the middle of the price continuum we are on with our competitors. For the thicker curtains, no other manufacturer makes the insulated curtains as thick, or as high, or retractable, so there is not a good comparison out there.
The company is the world’s best Aluminum Curtain Wall supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
While price is very important, the other question to ask is how our quality compares to that of our competitors. In that category, we are second to none. We are known for our attention to detail, our high quality workmanship, our ability to meet customers specific project and lead time requirements, and our outstanding, personalized customer service.
Life expectancy depends on the environment that the curtains are in, however even in tough environments, we expect that the curtains should survive and function for 10+ years. As an example, we have customer that have these curtains hung for over 20 years.
Our curtain products also carry a 6 year warranty (the longest in the industry!) on materials and workmanship.
Yes, the Insulated Curtains can be used outside. It is important that your sales associate knows that you plan to use this outside, so that they can suggest modifications to the construction, if necessary.
Please note that while the Insulated Curtains can be used outdoors, we cannot warranty them. This is because we cannot control the outdoor elements that the curtains will be exposed to. Wind, water, and direct sunlight can be harsh on the sewn construction and PVC vinyl outer layers of the Insulated Curtains.
