Because of its exceptional thermal insulation qualities and reputation for durability, Isospan D is appropriate for a wide range of weather and climate conditions.
A composite material like isospan D usually consists of multiple layers, each of which adds to the material’s overall performance. Polyurethane foam, aluminum foil, and other additives that improve the material’s insulating qualities and structural integrity are frequently used in these layers. In addition to offering superior heat resistance, this composition makes sure Isospan D is lightweight and manageable during installation.
Isospan D’s remarkable ability to efficiently control indoor temperature is one of its best qualities. Because of its ability to retain heat, it can help keep interior spaces comfortable by minimizing heat gain in warmer months and reducing heat loss in colder ones. Because of its energy efficiency, Isospan D can eventually result in lower heating and cooling expenses, making it a sensible option for environmentally conscious homeowners.
In addition to its ability to withstand heat, Isospan D is prized for its durability and resistance to moisture. It is appropriate for use on the walls, floors, and roofs of buildings because of these characteristics.

The main features of the film "Isospan D"
"Isospan D" is made up of two layers: protective and frame.
The sturdy woven canvas that makes up the frame layer is made of tiny polypropylene strips. He is in charge of the material’s mechanical strength, which includes its ability to withstand rupture, stretching, and other forms of deformation.
A thin layer of the same polypropylene covers one side of the woven base. She is the one who does most of the work and turns Isospan into a universal material by giving it resistance to moisture and significantly lowering its vapor permeability.
Such a structure provides waterproofing and vapor barrier type D, as does the addition of specific additives to the composition of polymer mixtures. The ensuing attributes:
- Resistance to mechanical damage during installation.
- The ability to withstand a large weight, for example, a snow mass tanking under the roofing, without stretching and rupture.
- Water detention – waterproofing "Isospan D" not only protects against condensate and random leaks of the roof, but can also withstand intense storm rainfalls.
- Small vapor permeability, which allows you to use Isospan D as a barrier vapor barrier.
- Long service life – the manufacturer guarantees the preservation of the properties of the material in the enclosing structures for 10 years, and the estimated period of its operation is 30 years as waterproofing and 50 years as a vapor barrier.
- Resistance to destruction by ultraviolet rays. Thanks to this, Isospan D as a temporary roofing up to four months.
Regarding the final characteristic, there is a crucial nuance to consider: UV stabilizers merely slow down the rate of UV-induced material degradation; they do not halt it. Consequently, the film’s overall service life will decrease the longer it is exposed to sunlight.
If the manufacturer’s estimated service life and warranty are to be believed, then the material will only save up to a week in the absence of protection.
The main technical characteristics
Rolls measuring 1.6 m wide, 43.75 m long, and 70 m 2 are used to produce isospan D. Work with D-type insulation is made extremely convenient by these dimensions: rolls are easy to roll out on a slope or surface, and they are simple to transport and lift to a height.
The remaining properties of the substance are:
- water detergent – at least 1000 mm of the water column;
- Density – 90 g/m 2;
- Breeding load for a strip of 50 mm:
- transverse – at least 890 N;
- longitudinal – at least 1068 N.
In this instance, the material is capable of withstanding a brief, minor overexposure to the upper limit of the temperature range. This could occur, for instance, if the roof is made of metal, during an unusually hot period. However, a consistent overabundance of this parameter will result in a discernible reduction in the material’s service life. In order to guarantee that the area beneath the roofing is cooled to a comfortable temperature, it is crucial to arrange appropriate subcutaneous ventilation.
What is the Isospan D intended for
The manufacturer’s instructions state that Isospan D can be used as follows:
- For the waterproofing of cold roofs. In this case, the film will protect the elements of the rafter system from getting wet due to condensation, as well as from the precipitation blew blown by a strong wind (mainly applies to snow).
- For steam and waterproofing flat roofs. That is, Isospan D can act as a replacement for traditional waterproofing materials based on bitumen.
- For steam and waterproofing of concrete ceilings. The film "Isospan D" is not suitable as a hydraulic barrier for wooden floors.
- As a temporary coating of roof and walls. If the roof is cold, then the waterproofing can then simply be closed with a roofing. For constant waterproofing of the walls "Isospan D" is not used.
Put simply, other than flat roofs, Isospan D should not be installed as part of a warm pie for any enclosing structures.
Rational (?) saving
Thus, "Isospan D" is a tried-and-true material that is robust, long-lasting, and UV-resistant. Cheap as well; a roll costs roughly 3,000 rubles. The fact that Isospan D has a sizable market share in Russia is not surprising.
In the context of its application material, it is excellent in theory. It works particularly well for sealing off chilly roofs. However, Isospan D remains a budgetary segment, with all the associated implications.
Its quality is not consistent, to start. Its properties allow for one party to be distinctly better than the other. Therefore, conflicting opinions about the content are common: one person may have seen a great movie and been pleased, but for someone else—if not a straight marriage—the content may have been noticeably worse than average.
This uniformity is not very important if Isospan D is used as a temporary coating or in a cake of a cold roof, as you can easily see defects and repair the waterproofing layer if needed. However, this becomes problematic if the film is a part of the insulated overlap. After all, you’ll need to break the screed in order to repair it.
Second, a very thin polypropylene film makes up the second layer. The Isospan D is well protected against ruptures by the woven canvas; however, it is not as effective against scratches, microcracks, and punctures on the second layer. That is to say, the panel may still appear "holey" while maintaining its visual integrity. In any event, the woven base will provide good drop protection against water vapor.
Thirdly, compared to polyethylene, another common vapor barrier, polypropylene has a theoretically higher vapor permeability. Isospan D thus fails as a vapor barrier when compared to a standard plastic film composed of the primary polymer.
But these flaws are not the primary issue. Ultimately, they are not very critical of "Isospana D"’sscope. The issue is that this film is frequently used for other applications, such as the hydro- and vapor barrier of insulated roofs and walls, and the overlap of wooden attics. This is because the material is inexpensive and there is a significant economic impact as a result. This is merely this hypothetical saving.
Isospan D acts as a vapor barrier, allowing a lot of water vapor to enter a heated building. Additionally, as a waterproofing, it prevents moisture from entering an insulation layer, which will cause it to get wet and lose a significant amount of its thermal insulation qualities. Not to mention the rafter system’s components’ moisture content.
Consequently, you should never use Isospan D for purposes for which it was not designed. even if significant savings are permitted.
How to fix "Isospan D": Instructions for use for the roof
Starting at the cornice, waterproofing should be installed on a cold roof. The smooth side of "Isospan D" is installed with a 10–20 mm sag between each rafter, running parallel to them.
A construction stapler is used to roll the roll and secure it to the rafters at a distance of 15-20 cm. Furthermore, the lumber needs to be allowed to dry, which requires at least a day of waiting, if it was treated with biological or fire protection. If not, polypropylene may react with the chemicals in the protective mixtures and be destroyed in areas where it comes into contact.
The first roll is rolled over by the second. There should be at least 15 mm of overlap between adjacent linens in both the horizontal and vertical directions. To guarantee the tightness of the waterproofing layer, they also need to be glued with sealing tape.
It is necessary for the joint between rolls in the same row to fall on the rafter. This is accomplished by cutting the remaining canvas so that, measured from the center of the rafter leg, a piece of 10-15 mm remains, and then another canvas is placed on top of it.
In the end, the waterproofing is sealed with racks, which are stacked on a plate of rafter legs parallel to it. It is advisable to use acrylic sealing tape to seal the attachment points on the rails that are accessible from below.
The roofing is installed and a crate is placed atop the control.
Isospan D shows to be a useful and efficient material for a range of roofing uses. Its aluminum foil and long-lasting polymers guarantee both strength and heat efficiency. By improving insulation qualities, this combination not only offers strong protection against weather-related factors but also helps save energy.
