Half a century of experience in the production of vapor barrier

The most frequent skepticism expressed by JUTA film buyers is that, in the opinion of most manufacturers, all polyethylene is ordered from China before construction insulation is manufactured, raising doubts about even Czech quality. Don’t worry; in contrast to many other brands, the company frequently notes that it uses only primary raw materials in production, which yields vapor barrier films of such high quality. These raw materials are solely "Czech," meaning no third-party materials are used.

Many viewers comment that the movies appear to be simple yet excellent! In contrast to Utah Isospan, Utah’s direct rival, these vapor barrier packs are plainly packaged as cellophane bags with a leaflet. The film appears sturdy, but the entire roll bears the inscription JUTAFOL. Additionally, JUTA vapor barrier reviews are almost always positive, and JUTAFOL is ranked highest in unofficial forum ratings for isolation price.

Why should this company believe? Firstly, JUTA is one of the largest European producers of polymer products for a variety of tasks. This company appeared in the second half of the XIX century and was at first a small enterprise for the production of fabrics and bags of plant raw materials – Jute, from where the name of the company itself came. Soon, polymeric materials have forced vegetable materials, and since the seventies, Utah began to produce subcutaneous steam and waterproofing films for construction, plus much more. And today she has many factories in the Czech Republic, where modern equipment and technologies are used, plus its own laboratory tests and evaluate independent certification centers. JUTA products are exported to many countries of the world, including Russia. Today, the representative of the Utah company and its distributor are the closed joint-stock company Effect-EKO.

To ensure that the customer never confuses windproofing with waterproofing, JUTA logically groups all of its insulating films and membranes under distinct names: Utacon, Utaco, and Utafol. The final group consists simply of vapor barriers, each of which is represented by a few distinct solutions that you can find at various points of sale using both the new term "vapor barrier" and the previous prefix "Utafol":

As you have observed, they differ greatly from one another even in appearance! Now let’s talk about their qualities! For this reason, we have prepared comprehensive illustrations for you that include each one’s technical specs, benefits, and installation features.

Utafol n90: to maintain microclimate

Classic vapor barrier from Utafol, Yutafol film N90. Strong, economical, and reinforced with a green stripe for the intersection, it can easily take the top spot in the market. This vapor barrier is designed to serve as the under-wrapping space vapor barrier for flat and pitched roofs. It is part of the thermal insulation layer. It works well in locations where maintaining the heat-and-pumped microclimate is crucial.

Utafol H90 is made as a three-layer material consisting of a polypropylene fiber reinforcement mesh that is laminated with polyethylene on both sides. suitable with every kind of insulation. Additionally, it needs to be mounted slightly tensioned and secured with brackets or double-sided adhesive tape.

Utafol n96 Silver: High strength for gap

The Utafol H 96 vapor barrier has the following appearance and is intended to form an impenetrable layer on the heat insulation surface:

This is the so-called bag fabric, which occasionally takes vapor barrier purchasers by surprise. It is composed of threads made of polypropylene that are further laminated at a specific temperature using a melt of low density polyethylene. Consequently, this product’s thickness approaches 20 microns. Unfortunately, the drawback of this type of vapor barrier is that its vapor barrier qualities are inadequate because polyethylene melts unevenly and has an uneven starting point for this task. Because a vapor barrier is a little weak, it works remarkably well as a waterproofing material for cold roofs.

The seller of this movie claims in this intriguing video review that Utafol H96 is still somewhat vapor permeable.

Such a movie is 100% appropriate for 100% if you do not intend to construct a "thermos" with non-hearing walls from the attic and you do not plan to set up a kitchen or bathroom there! The way the UTAFOOL film H 96 is installed on the slope is as follows:

Not regretting a vapor barrier adhesive tape is the most important thing, even though the final product is tidy and trustworthy! At the conclusion of the post, we will discuss each of their types.

Utafol N110 Standard: For most tasks

A more resilient and all-purpose film The Utafol N 110 Standard is made up of three layers of reinforcing mesh that are laminated with plastic wrap on both sides and soldered from polyethylene stripes. This is a contemporary classic found in most movie theaters. As you might have predicted, bilateral lamination produces the appropriate steam permeability, and the reinforcing mesh is intended to give the material strength. "Poblier" is written on the film itself, and her seal strip is red (green in Utafol N90):

In actuality, twisted thread-reinforced polymer mesh creates this type of vapor barrier. When such a grid is connected in the factory using a unique heat and adjustment technique, microcracks will be visible where the mesh and film are connected. They’re a lot here, but they’re worried that the steam may leak. Indeed, and in actuality, these microcracks only slightly deteriorate the material’s vapor barrier properties while having no effect on the material’s mechanical or waterproofing properties. Because of this, buyers are entirely correct in this case: the Utafol n 110 standard, with all of its benefits, has a significant minus.

One should primarily value a vapor barrier’s strength. Examining a few amateur experiments involving the strength of insulation films should pique your interest. Here’s an excellent illustration, as Utafol H110 maintains its integrity even after spending a lot of time in the sun and wind:

Setting up Additionally, Utafol H110 is fairly straightforward because the reinforced base prevents the film from overstretching or rupturing during use. The film itself of this vapor barrier is easily pulled on, lies evenly, and does not dangle, which is why people adore it. Furthermore, seasoned roofers suggest using a hammer stapler to affix this vapor barrier.

Utafol N110 Special: with a self -adjusting reagent

The film Utafol and the Special is distinguished by its low flammability due to the introduction of a self-adjusting reagent within the material:

Owing to the superior quality of the raw materials used in Utafol, this type of film outlasts the roofing itself and does not rot, grow mold, attract pests, or negatively impact the health of occupants of the attic over time.

Furthermore, it is essential if stove heating pipes are stored on roof slopes, as these situations frequently result in fires. In this instance, correctly using the required adhesive tape to seal the vapor barrier’s joints is crucial.

To facilitate installation, a black stripe is situated 12 cm from the edge on the surface of Utafol N special.

Utafol n al ali special (R110): with a reflective layer

The reflective aluminum layer sets the Yutafol film apart from other vapor barrier varieties offered by this manufacturer. She has more vapor permeable qualities because, as you are aware, aluminum has the ability to reflect heat and acts as a nearly perfect vapor barrier. The value of "n al" denotes the presence of an aluminum reflective layer, as you may have predicted. N Al is also available in a more sophisticated form that is designated R110, but it shares the same qualities:

When setting up warm floors and vapor barriers in rooms with a lot of water vapor, such as saunas and bath houses, Utafol n Al special and its more recent version of R110 are essential. Additionally, there are four layers that contain the entire secret:

• reinforcing mesh made of polyethylene strips;
• two laminating layers on both sides of the grid;
• reflecting the aluminum layer.

The only drawback to using this type of vapor barrier is that its paintings can only be glued with a specific kind of tape. It is possible to install UTAFOL NIL in both vertical and horizontal stripes, in a step-by-step master class and a schematic image:

Furthermore, Utafol N Al acts as an excellent vapor barrier for the ceiling due to its aluminum layer, which reflects heat and prevents water vapor from condensing in the decoration:

Utafol VAP: Smart membrane with SD control

The breathing vapor barrier membrane, known as Utafol VAP, is another intriguing product from JUTA’s latest generation. Its limited steam throughput was intended for homes with varying humidity levels. It is significantly lower than that of steam-barrier membranes but marginally higher than that of regular plastic films:

With Utafol VAP, you can easily expel wet steam by partially passing it into the outer layer of the roof. As a result, water diffusion resistance of steam. T.e. This type of membrane actually regulates the activity of water molecules’ movement at various temperature and humidity indicators, totally preventing the production of condensate and damp. Moreover, super-diffual membranes can be paired with this type of membrane to enhance the interior microclimate even more.

And let’s talk a little bit about the idea of SD to better grasp what is meant. We are discussing the thickness of this resistance as well as the coefficient of resistance of water vapor diffusion. The truth is that natural convective transfer of air masses takes place when there is a temperature differential between the interior and exterior of a residential building. Stated differently, a warm stream emanating from a warm room will constantly aim for a cooler external environment, particularly in cases where there are joints and inadequately accumulated vapor barrier overflow.

The movement can be attributed to the variation in partial pressure. Except for carbon dioxide and oxygen, all air contains gaseous water that is invisible to the human eye. Additionally, each air has its own pressure, which might differ even between two adjacent living rooms housed under one roof.

There is more water in the air and a higher relative humidity in proportion to the steam’s partial pressure. In the event that there is a link between these two rooms—such as seams or cold bridges—partially pressure and temperature differential will attempt to equalize. Water steam, therefore, will consistently draw in a dry room until this distinction is eliminated. This concept is measured by the SD coefficient alone. It’s not always the same attic that requires a "tight" vapor barrier.

Technically speaking, all producers of thermal insulation made of mineral and basalt are combined with the Utafol vapor. However, it cannot be used in hot, humid rooms such as saunas or baths, or in roof pie installations where a hydraulic boarier was installed instead of a superdiffusion membrane, as this will prevent any remaining humidity from escaping.

To sum up, the Czech vapor barrier, Utafol, is unique in the market due to its wide range of models and strong technical specifications. Utafol provides dependable protection against condensation and is designed to manage moisture in buildings, extending the life and resilience of roofs and other structures.

Utafol’s construction is one of its main advantages. Crafted using premium materials and cutting-edge production methods, it offers an effective barrier to stop water vapor from seeping into insulation layers. This feature not only improves a building’s thermal efficiency but also lowers the possibility of mold and moisture buildup, which helps to maintain a healthy indoor environment.

Additionally, Utafol comes in a range of models designed to fit various building specifications and environmental conditions. There is a suitable Utafol variant designed to meet specific needs, whether for residential, commercial, or industrial applications. This variant offers flexibility and reliability across a variety of projects.

Utafol is preferred by contractors and builders due to its superior technical qualities as well as its simplicity of installation. Utafol streamlines the construction process, reducing time and labor costs while maintaining a high standard of performance. It does this by providing clear guidelines and compatibility with a range of roofing systems.
