The type of panels you choose to insulate your freezer room is going to make a big impact. Everything from lifespan to energy efficiency will be affected by your choice, so it makes sense to consider all available options and pick the one that best fits your needs.
Once you check out those available options, you're likely to find that polyurethane is the most popular choice. Here are just four reasons it's such a great option for freezer room insulation.
1. Low Thermal Conductivity
Thermal conductivity relates to how easily heat transfers from one surface to another, and polyurethane boasts very low thermal conductivity. This makes it ideal for keeping the interior of your freezer cool. In order to match its ability to keep a freezer room cold, other materials have to be much thicker. Compare a polyurethane insulating panel against a polystyrene panel and you'll notice the latter must usually be twice as thick to provide the same cooling performance. This means polyurethane panels can provide effective cooling without having to take up much space or eat into your freezer room's storage capacity.
2. Closed Cell Structure
Polyurethane is mostly made up of closed cells. This makes it superior to open-cell insulation, which is generally softer and more flexible. Thanks to polyurethane's closed cell structure, it offers excellent structural strength, which means it is very hard to damage it. That closed cell structure also allows polyurethane insulation to offer superior moisture resistance, so water ingress isn't going to be a problem.
3. Adheres Permanently
Many types of freezer room insulation need to be glued to the metal that makes up the outer layer of panels. Unfortunately, this can mean they separate over time, leaving a gap between the insulation material and the panel. Such gaps interfere with a panel's ability to maintain cool interior temperatures, but you can avoid them entirely by opting for polyurethane. It permanently adheres to metal panels, so it's never going to pull away.
It's becoming increasingly important to consider how construction materials impact the environment, so you'll be pleased to know that polyurethane foams do not emit volatile organic compounds (VOCs) or require ozone-depleting blowing agents. This means they aren't bad for the environment, and the fact that they provide such exceptional insulation reduces the amount of energy needed to keep a freezer room cool. As such, they can help lower both your environmental impact and your energy bills.
