Which profile is better for plastic windows 60 or 70. Plastic profiles ...

The width of the plastic profile, which one to choose, what affects, 60 or 70 mm | All about plastic windows

Almost all manufacturers of plastic profiles, both domestic and foreign, have a range of products not limited to one product. Usually this is a line of five to six products of different widths and number of chambers. Moreover, nowhere is it really explained which one is better, what these indicators affect, and why one should choose one or the other.

TOP BEST are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

It is worth noting that products with a width of 70 and 80 mm appeared not so long ago, about fifteen years ago, and before that there were only 60 mm products. It is these systems that experts recommend for private glazing, motivating the buyer with the fact that they are more likely to let the cold through. However, studies carried out by the manufacturers themselves indicate that with the same number of chambers, products with a size of 70 mm are warmer by only a few percent. Despite the fact that windows from a larger system can be more expensive by ten percent or even thirty percent.

Systems of 60 mm profiles such as Rehau Euro Design or Veka EUROLINE are now positioned by sellers as economy class products that are used for mass glazing of residential buildings, for example, new buildings. But, some time ago, they were recommended for private glazing, and even in our country there are thousands of such windows, and their owners do not complain about the lack of heat with proper care of the sealant.

So if only this indicator would affect the heat in your house, the manufacturers themselves would strive to increase it, and this indicator would reach 100 and 200 mm. However, this does not happen and the maximum known width is 90 mm. So the point is not at all in this, but in something else.

In fact, the thermal conductivity of the profiles is influenced by the multi-chamber nature. According to research, a product of the same width, but with a different number of chambers, can differ in thermal conductivity by twenty percent or more. Therefore, it is worth paying attention to this indicator. The four-chamber profile is much warmer than the three, even if it is smaller. In harsh climates, it is worth paying attention to the five-chamber systems.

Conclusion: the width is not so important as the number of cameras. The more cameras there are, the more heat will remain in your home or apartment.

Which profile of a plastic window is better to choose?

One of the most important elements when choosing a plastic window is its profile, since it is he who is an indicator of the strength and, accordingly, the durability of the overall structure.

Today there are a huge number of companies producing plastic windows and, if you look visually, they have practically no differences. The difference in quality can be seen after a while, when deformations of the windows will be noticeable, namely, the formation of cracks and distortions.

Profile for PVC windows, main characteristics and types

The profile is the basis of the overall structure of the window, which is made of wood and aluminum. But today, window profiles are mainly made of PVC or polyvinyl chloride. Due to the fact that they have metal inserts, they have a fairly high strength. And the presence of internal, air cavities makes it possible to significantly increase thermal insulation.

As for the characteristics of plastic windows, they are classified according to European standards, mainly in terms of the thickness of the outer and inner walls of the window profile. These include:

  • Class A profiles. This is one of the most optimal profiles that have good noise and heat insulation. Its outer wall is from 2.8 mm thick, and the inner wall is from 2.5 mm .;
  • Profiles of class B. The width of the walls of such a profile is slightly different from that of class A and therefore they are cheaper and less durable. Since, the thickness of the outer profile is from 2.5 mm. but the inner one is only 2.0 mm.;
  • Profiles of class C. Window profiles that do not belong to A and B class are not subject to such rigor in meeting the requirements.

Important: the quality of the profile can also be indicated by the fact that on each of their bottom there should be a special marking, which is located on the inside of the package. It indicates the manufacturer, the date when they were manufactured, as well as the shift number.

Quality matters when choosing a profile

An important point when choosing a plastic profile, in addition to the declared characteristics, is the quality of the product itself. The production of a profile is a complex technological process that requires the organization of constant production control and verification of the finished product. ExProf * is the largest Russian manufacturer of window profile systems, produces a whole range of type A profile systems with various mounting widths. Type A is the highest profile wall thickness according to GOST.


Photo: A profile is stronger than a B profile. The wall thickness affects the strength of the profile and welding in the corners of the window structure.All exprof profiles are available in class I (universal) for climatic conditions, that is, they are suitable for use in any climate from the subtropics to the Arctic.

Glass unit ↑

The amount of glass in the window has a significant impact on the performance and price of the entire structure. The most common is double glazing, but today you can order a window with single or triple glazing.

The warmest "triple" windows are considered, but it should be borne in mind that dimensions of the profile of plastic windows will be more, moreover, this option weighs a lot and requires a high quality installation and the stability of the structure itself. The coldest will obviously be a single glass unit, therefore it is recommended to use it only in summer or unheated houses. And only a double-glazed window is rightfully considered optimal in terms of technical characteristics, because it allows you to keep warm in any room throughout the year.

Profile classification ↑

There are such types of plastic window profiles:

The company is the world’s best 60mm uPVC profile supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

  • "A" class has a thickened outer wall, it is the optimal profile not only for windows, but also for frame glazing, doors. Products of this class are required to have a RAL certificate.
  • "B" class acts as a lightweight profile with a thin outer wall. This profile is also called "object".
    Important: the lower cost attracts buyers of plastic windows, however, it does not always guarantee the ideal preservation of the characteristics of the window for many years of its operation.

    Window structures made of "object" metal-plastic profiles are considered an economical option, which is implemented by many manufacturers

Majority rating ↑

In recent years, has been compiled rating of plastic profiles for windows, which included only those window constructions manufacturers that have won the trust and respect of users of their products.

  • The largest number of complaints and complaints were caused by their window owners. THE JUICE, Plaufen, Weltplast
  • Good profiles can be purchased from manufacturers: Aluplast, Funke, Artek, Proplex and CEE
  • The best profiles are manufactured by companies such as Veka, Rehau, as well as Trocal and Salamander

How long are PVC windows

The service life of a window depends on the quality of all structural elements: profile, double-glazed windows, gaskets, fittings. Assembly and installation are not the least important. Usually, manufacturers give a guarantee for a period of 5 to 10 years, but the actual duration of the use of structures is much longer - several tens of years.

The profile lasts the longest - 50-60 years. All other elements - up to 10-15 years, subject to the rules of operation and regular maintenance. But double-glazed windows, fittings and a seal can be repaired and replaced.

To extend the service life, you must:

  • Timely troubleshoot the opening mechanism.
  • At least once a year, clean and lubricate the moving parts of the fittings from dirt and grease.
  • Clean the drainage holes and sealant from dust twice a year.
  • Lubricate the sealant in spring and autumn to protect it from moisture and sun.

For professional and high-quality window care, you can purchase a special kit that includes a lubricant for fittings and gaskets and a soft cloth for cleaning dust.

Features to watch out for

In addition to the technical characteristics of the plastic window profile discussed above, there are several consumer indicators that must also be considered. These are, first of all:

  • the number of chambers in the cross section;
  • the width of the system for the installation of a double-glazed window;
  • manufacturer of window materials.

It is also important to find a good installation supplier company, which employs qualified craftsmen. Unless, of course, you are going to install the window yourself.

Number of profile cameras

There can be two types of prefabricated plastic elements in the construction of the window. The first is a load-bearing window frame made from a basic profile. The second type is an opening plastic sash for installing a double-glazed window. In both cases, the profile structure is hollow and in its section it consists of chambers separated by partitions, which can be from 3 to 7.

The larger the number of chambers, the higher the strength of the structure and the higher the performance characteristics. Each wall and partition has a specific function and therefore the position and thickness of the profile elements are calculated mathematically based on experimental data. The most popular structures in central Russia have 5 cameras.

Profile width

The installation width of the frame determines which profile can be installed in this window and the number of chambers in the internal section. Both of these indicators greatly affect the thermal and sound insulation characteristics, the total weight of the structure and the cost of the window.

Single-chamber double-glazed windows in the classic version of two glasses have a width of 58 mm and must be installed in a profile of the corresponding section. For two-chamber structures, the profile width must be at least 70 mm. Accordingly, 3-chamber - 90 mm and 4-chamber 110 mm. The last two types of windows belong to the "Premium" class and are installed only in the regions of the Far North.

Famous manufacturers of PVC window profiles

The most popular brands in our country include the products of the following companies:

  • KBE, Rehau and Veka from Germany;
  • Montblanc from Austria;
  • Salamander from Sweden;
  • Kaleva, Proplex and Panorama from Russia.

All European companies, except for Salamander, have an established production of plastic window profiles in our country. Therefore, they are sold at quite affordable prices for most owners of apartments, private houses, office buildings and other buildings.

Profile developed in Germany

The line of German profiles contains products with the number of chambers from 3 to 6 and a width of 58-90 mm. Each of these manufacturers offers not only a white profile, but also a variety of factory-applied color coatings.

The most popular is finishing with polymer films imitating various types of natural wood. The main advantages of the products of European companies include:

  • high rating and excellent workmanship;
  • wide range of offered models;
  • affordable democratic prices;
  • plastic does not change color when exposed to solar ultraviolet radiation.

It should be noted that materials produced on the territory of Russia do not differ from analogs produced at European factories.

Austrian windows

The Mont Blanc company (Mntblanc) produces the most budgetary high quality plastic windows. The production is located in the Moscow region of Elektrostal. Offers on sale 7 types of profiles with widths from 58 to 120 mm with the number of chambers from 3 to 5.

Wider means warmer and more reliable? ↑

Profile width of plastic windows is one of the main characteristics. Most manufacturers of window constructions promise us a few extra millimeters to the standard profile width in advertising campaigns, but is there really a use for these millimeters?

Most often, on the market for window structures, you can find the following basic offers:

  1. 58mm "classic" profile
  2. 60mm profile (for facility construction)
  3. 70-80mm profile with increased installation width (for high-rise construction)
  4. 90mm profile

Width 58 mm due to the "classics" - wooden frames, which have replaced plastic windows. Today, a profile of 58 mm freely allows the production of modern warm window structures that meet the requirements of the vast majority of buyers living in various climatic zones.

Please note: subject to correct production and installation, this window profile deserves to be called the best for any room.

70 mm - a proposal that first appeared in the distant 80s. This profile has higher soundproofing and heat-insulating characteristics, it is revered among the inhabitants of Russia.

90 mm - a product considered premium. This proposal appeared no more than five years ago. A profile of this width allows the use of a double-glazed unit up to fifty millimeters thick and today it is the unsurpassed leader among all window profiles with high energy-saving performance.

Of course, even 90 mm today is far from the limit. The Russian market today offers such profile systems, the width of which is 104, 124 mm. What does it do? If the "classic" profiles allow you to mount double-glazed windows with a width of no more than 32 mm, then, for example, 70 mm allows you to install a 42-mm double-glazed window, and a 90-mm profile - 50 mm double-glazed windows, and so on.

Basically, such glazing systems are recommended for houses that are characterized by a predominantly passive heating system.

In many ways, the choice of the width of the window profile depends on where it will be installed, for example, in a country house, in an office, in a vestibule door or in a store front door. Climatic conditions are also an important factor.

Profile certification ↑

Each profile from which plastic windows are made must be certified. The most significant certificate is the certificate RAL, he gives comprehensive information not only about the type of product, but also about the place of its production. In other words, a profile of the same brand, however, made at completely different enterprises, does not always have such a certificate.

For example, a distinctive feature of the VEKA window profile manufacturer is the RAL certificate not only from the main German plant, but also from all subsidiaries, including Russian production bases in Moscow and Novosibirsk.

What You Need to Know About Window Frame Thickness

When choosing new windows for your home, one aspect that is often overlooked is the thickness of the window frame. Whether you’re renovating a period property or installing modern aluminium windows in a contemporary space, frame thickness plays a crucial role in window performance.

It affects everything from energy efficiency and durability to aesthetics and compliance with building regulations. This guide will walk you through the key considerations when choosing the right window frame thickness for your residential property.

What Are the Different Window Frame Options?

Window frames come in various materials, each with standard thickness ranges that influence their performance. Some of the most common materials include:

uPVC

  • uPVC windows are popular in the UK due to their affordability, low maintenance, and energy efficiency. The thickness of uPVC frames typically ranges from 60mm to 80mm. BSF Windows offers a selection of uPVC frames, with features like multi-chambered profiles for better thermal insulation, making them an ideal choice for homeowners looking to reduce their energy bills.

Aluminium

  • Aluminium window frames are known for their sleek, slim profiles and strength. These frames are thinner compared to other materials, with thicknesses ranging from 70mm to 85mm. This slimline design allows for more glass and natural light while maintaining durability. BSF Windows provides premium aluminium windows, engineered with thermal breaks to improve energy efficiency.

Timber

  • Timber frames are a traditional option that adds warmth and charm to period or traditional properties. These frames are generally thicker, ranging from 75mm to 95mm, due to the natural properties of wood. Timber windows at BSF are crafted with sustainable materials and provide superior insulation and durability, making them a perfect fit for those looking to maintain a classic aesthetic.

Each material has unique benefits in terms of energy efficiency, security, and style. When choosing window frames, it’s important to consider how the thickness of the frame will complement the overall look and function of your property.

With natural insulating properties, timber windows can reduce energy consumption and help maintain a comfortable indoor environment. BSF Windows’ timber frames are designed for long-lasting performance, ensuring they remain a beautiful and functional part of your home for years to come.

Which Frame Material is More Energy Efficient?

When considering window frame thickness and energy efficiency, it’s important to look at the material used. uPVC and timber frames generally provide the best thermal efficiency due to their insulating properties.

  • uPVC frames: These often feature multi-chambered profiles, which trap air and create an effective barrier against heat loss. uPVC windows from BSF Windows are designed to meet the highest energy standards, reducing your home’s carbon footprint and energy bills.
  • Aluminium frames: Although aluminium is a conductor, modern designs incorporate thermal breaks within the frame, improving their energy efficiency. BSF’s aluminium windows are engineered for optimal insulation, making them an excellent choice for contemporary properties.
  • Timber frames: Wood is a natural insulator, making timber frames one of the most energy-efficient options available. At BSF Windows, our timber windows combine traditional craftsmanship with modern energy-saving features, ensuring your home remains warm in winter and cool in summer.

For homes in Surrey, Sussex, and the surrounding areas, where climate control is crucial, choosing a thicker frame with superior insulation properties can make a noticeable difference in both comfort and energy costs.

Are There Building Regulations for Certain Window Frames?

In the UK, window installations must comply with Building Regulations, particularly in terms of energy efficiency, safety, and ventilation. Frame thickness plays a part in meeting these standards, particularly when considering factors like window energy rating (WER) and thermal efficiency.

  • Energy Efficiency: Building regulations require that all new windows meet a minimum energy efficiency standard. This includes specific U-values, which measure how well a window prevents heat from escaping. The thickness and material of the window frame will impact this rating. Thicker, insulated frames will typically offer better U-values, ensuring compliance with regulations.
  • Safety: For certain installations, such as those in upper floors, thicker frames may be required to accommodate safety glazing or boosted locking systems. BSF Windows offers windows designed to meet or exceed safety standards, giving you peace of mind along with energy savings.

How to Choose the Right Thickness for Your Project

Choosing the right window frame thickness depends on several factors, including your property’s location, the style of your home, and your specific needs. For example:

  • Weather: In areas prone to colder winters or hotter summers, thicker frames with better insulation will provide year-round comfort. Double or triple glazing paired with a thicker frame can offer superior thermal efficiency, reducing heat loss and lowering your energy bills.
  • Aesthetic Appeal: If you’re renovating a traditional property, you might prefer timber frames, which tend to be thicker. For modern homes, aluminium frames offer a sleek look with their slimline design.
  • Security and Durability: Thicker frames often mean stronger windows, particularly when it comes to materials like timber or aluminium. Whether you’re looking to improve the security of your home or ensure long-lasting durability, BSF Windows provides a range of options designed to meet your specific requirements.

Measuring Frame Thickness and Understanding Manufacturer Specifications

When comparing window frames, it’s important to understand the manufacturer’s specifications. The thickness of the frame will usually be listed in millimeters, and it’s worth measuring the existing frames in your home to ensure compatibility with new installations.

At BSF Windows, our experts can guide you through the process, helping you choose the right frame thickness for your property. Whether you’re opting for our uPVC, aluminium, or timber windows, we’ll ensure your new windows meet both your aesthetic and functional needs.
