Closed-cell PE foam
CLIMAFLEX naturefoam is described as foamed, closed-cell polyethylene. The product cards cover various pipe sizes and insulation thicknesses.
Choose the right pipe insulation
Pipe insulation is selected according to the outside diameter of the pipe, insulation thickness, material and installation method. Here you will find closed-cell PE foam, stone wool with aluminum coating, self-adhesive versions and tools for straight pipes as well as shaped fittings.
Choose pipe insulation for the job
When choosing pipe insulation, start with three details: the pipe size, insulation thickness and installation method. A specification such as Ø 54 mm x 13 mm combines the matching pipe diameter with 13 mm of insulation material. Looking at these two numbers separately makes it easier to distinguish similar sleeves. The product information also shows whether a piece is 1 m or 2 m long and whether it has a self-adhesive slit edge.
Insulation sleeves are available in various combinations for straight pipes. According to the product description, several 2 m CLIMAFLEX products are divided into two 1 m sections. This matters when planning because a 2 m length is arranged as 2 x 1 m sections, so the sectioning needs to suit the work area. Bends and tee fittings require a different cutting pattern from a straight run.
Read the sizes and check them against the pipe
For the listed sleeves, the first measurement gives the pipe diameter and the second gives the insulation thickness. Product data includes, among others, Ø 22 mm x 13 mm, Ø 28 mm x 20 mm, Ø 35 mm x 13 mm, Ø 42 mm x 9 mm, Ø 54 mm x 20 mm and Ø 60 mm x 13 mm. These values are variants of individual products, not a general specification for every pipe.
- Pipe size: measure the outside diameter of the existing pipe.
- Insulation thickness: compare the second number with the available space.
- Length: distinguish between 1 m, 2 m and the sections stated in the product information.
- Seam: check whether the sleeve is pre-slit or has a self-adhesive slit edge.
A caliper provides the more accurate diameter; with an existing installation, the pipe's readable marking can also help. Do not choose between two sizes based on the image. The size, insulation thickness and installation conditions need to be considered together.
Compare the material and installation method
The product cards list several CLIMAFLEX versions as flexible, closed-cell PE foam made from NMC Naturefoam. They are described for heating/plumbing applications; depending on the product, they may be pre-slit or have a slit edge that is self-adhesive on both sides. This keeps the comparison clear: first the right pipe size, then the insulation thickness and finally the installation method.
Stone wool with aluminum coating
The product information for 22 x 20 mm describes a 1 m length made of stone wool with an aluminum coating. The product name also includes GEG 100%.
Self-adhesive slit edge
XT products are listed with a slit edge that is self-adhesive on both sides. Other CLIMAFLEX versions are described as pre-slit. The seam design therefore determines the installation step.
Straight pipes, bends and tee fittings
Before cutting, note the pipe route with straight sections, bends, tee fittings and valves. Straight sections can be planned with a suitable insulation sleeve. With a self-adhesive XT model, the slit edge is closed after the sleeve is put in place. With a pre-slit sleeve, it is opened and closed without the additional gluing step.
The range includes a miter box for cutting insulation around bends and tee fittings. The product description presents it as a cutting aid for bends and tee fittings and recommends working on the shaped fittings first, followed by the straight pipes between them. This makes it possible to determine the required length at each transition separately. The miter box itself is listed as a red plastic product.
Consider heating and plumbing separately
Several product cards list heating/plumbing applications. Even so, the specific system remains decisive: the pipe diameter must match the pipe, the insulation thickness needs enough space, and the installation method must suit how accessible the pipe is. A product with 9 mm insulation thickness cannot automatically be replaced by one with 13 mm, even if the pipe diameter is the same.
Other technical tasks have their own product areas, such as cooling & climate. This makes it easier to find a suitable product group, but it does not replace checking the installation requirements. For a long run, also take into account the length stated in the product name or product description.
Three product examples with specific data
The following cards show different combinations of pipe size, insulation thickness, length and installation method. Each detail refers to the product named.
CLIMAFLEX XT: Ø 54 x 13 mm
2 m long, described as 2 x 1 m, with a self-adhesive version and listed for heating.
Stone wool ALU: 22 x 20 mm
1 m long, made of stone wool with aluminum coating and listed with GEG 100% in the product name.
CLIMAFLEX XT: Ø 22 x 13 mm
2 m long, described as 2 x 1 m, self-adhesive and listed with 50% GEG in the product name.
Subcategories for narrowing the selection
The subcategories organize pipe insulation by product group or installation task. Four entry points help narrow the search before comparing individual sizes.
Climaflex insulation
This entry groups the insulation sleeves identified as Climaflex and makes it easier to compare size, insulation thickness and length afterward.
Heating pipe insulation
This entry focuses on use with heating pipes. The size and insulation thickness remain the key comparison values in this view as well.
Pipe insulation for bends
This area is intended for bent pipe sections. A miter box from the range supports work on these shaped fittings.
Self-adhesive insulation
This entry collects versions with a self-adhesive design. When selecting, also check the pipe size, insulation thickness and sectioning.

FAQ about pipe insulation
Which size specification must match the pipe?
The pipe diameter must match the first value in the product specification. With Ø 42 mm x 13 mm, 42 mm is the pipe diameter and 13 mm is the insulation thickness. Measure the existing pipe and compare both values.
What does the second number mean?
For the insulation sleeves mentioned, it indicates the insulation thickness. The range includes, for example, 9 mm, 13 mm, 20 mm and 25 mm. The larger value needs more space, so the wall clearance and installation location must be taken into account.
When is a self-adhesive version suitable?
This design is an option when the slit edge should be bonded after the sleeve is put in place. CLIMAFLEX XT is listed with a slit edge that is self-adhesive on both sides. Pre-slit versions, by contrast, are opened, placed around the pipe and closed.
How do PE foam and stone wool differ?
The product cards describe CLIMAFLEX as closed-cell PE foam and another product as stone wool with aluminum coating. Here, PE appears as a flexible sleeve; the stone wool product is 1 m long and specified as 22 x 20 mm.
How should I plan 2 m products?
Several CLIMAFLEX products mentioned are described as being supplied as a 2 m length divided into 2 x 1 m sections. Plan the run with two 1 m sections and compare this sectioning with the work area.
What do I need for bends and tee fittings?
A miter box for cutting insulation around bends and tee fittings is listed for these shaped fittings. Its product description names bends and tee fittings as the cutting task. Cut the shaped fittings first, then complete the straight sections between them.
Quick check before buying
- Measure the outside diameter of the pipe.
- Check the pipe size and insulation thickness separately.
- Note the length and sectioning of the version.
- Choose a self-adhesive or pre-slit installation method.
- Plan the cutting sequence for bends and tee fittings.
This keeps the choice focused on the actual measurements and installation conditions.
