To install pipe wrap insulation, tape one end of the insulation to the pipe. Then wrap the insulation around the pipe, aiming for tight spiral loops with overlaps of half an inch or more.

Another point at which foam pipe insulation needs cutting is at T branches within the plumbing system. To create a piece of insulation that covers a T branch, cut a 90-degree wedge out of the main section of pipe insulation. This will allow the insulation to be fitted on the main pipe with space for the other pipe to branch off. Then take a separate piece of insulation, and cut the end with two 45 degree angles, to form a point. This point then should fit neatly into the 90-degree cutout in the main piece of insulation. Then, just tape the joints together to ensure no heat loss occurs. All you need to do is wrap a string or a flexible tape measure around the outside of the pipe. Now, take this measurement and divide it by pi(pi = 3.1415). This calculation is the plumbing pipe’s Outside Diameter that you can use to look up the Nominal Size. Don’t sweat it, we will get you measuring pipe like a pro in no time! Our free pipe wrap-around ruler is perfect for measuring the size of any type of plumbing pipe – including iron, PVC, copper, and more. When installing pipe wrap insulation, it is crucial to ensure that no areas are left exposed, and the insulation doesn’t slip as you move along the pipe. Slide the Pipe Wrap on top of the shuttering being used for the making good. Ensuring that the bottom edge of the wrap will be exposed in the floor slab when the shuttering is removed.Pipe collars may be a more suitable solution for your project, discover the differences between pipe wraps and collars in our blog post.

Rubber pipe insulation such as Armaflex from Armacell is a closed-cell, elastomeric rubber pipe insulating system. Most commonly used to prevent condensation and humid environments from occurring, rubber pipe insulation tends to have high water resistance. However, it can also be used for thermal insulation as it has low thermal conductivity.The downside of this technique is that you need access to an open end of a pipe to measure across. If your plumbing pipe is already installed, it might be impossible to measure your pipe this way. Outside Diameter Measurement Make good around Pipe Wrap with either Firestop Compound or traditional mortar to the full depth of the seal. Soldering copper pipes with an open flame may seem intimidating but fear not. With our guide, we will take you from beginner to soldering pro in no time!

What if you don’t own a set of callipers or math was your most hated subject in school? We hear you! Important: If you are using permanent mineral wool shuttering for Firestop Compound, cut out the shuttering to ensure that the bottom edge of the Pipe Wrap can be viewed from the soffit below. If this is not carried out the intumescent material will be insulated and shall lead to a product malfunction. Once you reach a corner or bend in the pipework, there are a couple of options for installing the pipe insulation.

If you can’t see with your peepers what size of pipe you are looking at there are a few ways to measure your plumbing. How Do I Measure My Pipe Size?
