Beim Dachfenstertausch gelten prinzipiell die gleichen Empfehlungen. Wenn der Dachboden nicht zum Wohnen oder zum einlagern empfindlicher Gegenstände verwendet wird, muss man hier nicht zwingend auf energieeffiziente Fenster umrüsten. Wenn man allerdings den Dachboden zum Wohnbereich ausbauen möchte, empfiehlt es sich häufig die Dachfenster zu erneuern.

Wann muss ein Dachfenster ausgetauscht werden?

Bei beschädigten oder undichten Dachfenstern kann leicht Wasser eindringen und das Mauerwerk beschädigen. Wenn die Dachfenster nicht mehr richtig abdichten, sollten Sie über den Austausch der Dachfenster nachdenken, um Schimmelbildung oder Schädigung des Gebäudes zu verhindern.

Die Kosten für neue Dachfenster hängen so wie bei Fassadenfenstern von Material, Isolationswerten und Größe ab.

In unsrem online Baumarkt finden Sie riesigen Auswahl sowohl der Dachfenster, Dachfenster Kunststoff als auch passender Zubehör wie Dachfenster Rollos, Markizen usw.

Buildings of SOLBET's aerated concrete

Various types of buildngs can be built from SOLBET aerated concrete: from single-family houses to commercial buildings and industrial buildings. Blocks from SOLBET can be used for the construction of single- and multi-layers on both load-bearing and partition walls. The low dimensional tolerances for the flat blocks mean that they can be masonry with thin joint glue. Buildings made of SOLBET products are solid, ecological and modern.

Is aerated concrete an ecological material?

The company SOLBET works in a closed ecological cycle: starting with the production up to the waste management. The manufacturer continues to invest in modern, effective and environmentally friendly solutions. Two wind turbines, the total output which covers the energy needs of the entire company on windy days, are the company's contribution to the pro-environmental attitude. Only natural raw materials (limestone, quartz sand, water) are used to produce the aerated concrete. The recycling of post-productive waste protects natural raw resources. The low weight of the blocks saves energy during transport. The products are environment friendly and do not emit any harmful substances.

Energy saving

Building with SOLBET's products allows to save energy and heating costs. The special properties of lightweight concrete protect the building's interior from both the summer heat and the winter cold. Thanks to the excellent thermal insulation value, even extreme outdoor temperatures never enter the living space. In this way, the aerated concrete of SOLBET ensures a high standard of living and guarantees that valuable energy is saved. This is confirmed by the well-known test facilities and institutes for material control in Germany such as MP Berlin. This institute carried out the certification tests for the SOLBET materials and confirmed the value of thermal conductivity λ = 0.10 [W / mk].

Solid and stabile construction - solid houses of lightweight concrete

The aerated concrete SOLBET guarantees suitable stability of the buildings without affecting the elasticity of the architectural project. The high compressive strength of 2.75 N / mm² makes this material suitable for building bearing and non-bearing walls in all kinds of buildings with different construction and use (also multi-storey buildings). Because the SOLBET blocks are also relatively light, your house will be built quickly and efficiently.

An optimal indoor microclimate

The unique structure of the SOLBET aerated concrete blocks guarantees a healthy and pleasant indoor climate. The low thermal conductivity of the building material makes it possible to achieve a constant temperature inside despite external temperature changes. The porosity of lightweight concrete blocks also ensures that excess moisture is absorbed and collected from the rooms and then released again if the room air is too dry. The uniform porosity ensures that the heat conduction is the same in all directions and that the building material is open to diffusion, ie. breathe.

Acoustic insulation

The sound-insulating properties of building material depend on its own weight. In the case of walls made of aerated concrete, it was found that, due to the porous structure of the aerated concrete, the sound level in relation to its sound-insulating properties is 2 to 3 dB higher than the sound acoustics of partition walls and materials with the same dead weight.

The homogeneous distribution of the air pores in the building material ensures uniform sound insulation in all directions. The walls made of aerated concrete were examined for sound-absorbing behavior in the test institute for structural engineering and received the display value for sound insulation corrected by 2 dB and display value for acoustic insulation RA1R and RA2R.

Is lightweight concrete fire resistant?

Aerated concrete from SOLBET is made of non-combustible material. Solbet blocks won't be affected by a fire and thus form a barrier against the spread of fire. In the same way, lightweight concrete from SOLBET emits no pollutants or toxic fumes. A partition wall with a thickness of 11.5 cm also has fire class EI 120. The higher fire class REI 240 can be achieved with a wall thickness of 17.5 cm. SOLBET materials guarantee the highest level of safety, even without additional fire protection systems. The fire resistance tests for SOLBET products, which are carried out regularly in the test laboratories, confirm the high level of safety without exception. Because aerated concrete is extremely resistant to high temperatures, the chamber where fire tests are performed on other building materials is built of aerated concrete.

Highest resistance to atmospheric factors

SOLBET's lightweight concrete  is resistant to many atmospheric conditions. The chemical composition of aerated concrete prevents the development of dangerous microorganisms. Due to the strongly alkaline reaction of the material and the rapid attenuation, no bacteria, mold or fungi develop on the aerated concrete surface.

All types of walls

Each SOLBET product is manufactured with very high dimensional accuracy. The blocks and u-blocks are offered in many dimensions. This means that many types of walls can be raised with SOLBETl. The simple processing of the aerated concrete elements means that there are no architectural boundaries. With the lightweight concrete elements, you can build from the basement to the roof in a flexible way. With those blocks even arched partitions, efficient fireplaces or a bathtub coating can be built.

What is the cost of lightweight concrete blocks?

Due to the low weight and the relatively large dimensions of the building blocks of SOLBET, the construction work is simple and efficient. By using lightweight concrete, the construction time can be significantly shortened, which helps to reduce your costs. A block of aerated concrete can replace several bricks. Thanks to the profiled side surfaces of the blocks, it is not necessary to fill the horizontal joints with thin-joint glue, which speeds up the construction work and reduces the purchase costs of thin-joint joints. Another advantage of lightweight concrete blocks is their high dimensional accuracy, which allows them to be built with a thin layer of mortar. Building walls is like a child's play - the individual block parts can be easily cut to the desired size and their construction only requires the use of simple tools. The best proof is the construction of the International Fund "Habitafor Humanity", which was built from SOLBET's materials and by the volunteers.

The highest quality

Many years of experience, the trained employees, the modern production system and the high level of ambition help to manufacture SOLBET products with the highest possible quality. The quality management system has been introduced in SOLBET factories. SOLBET products received ISO 9000 and OHSAS 1800. Every block that is manufactured, before it leaves the production facility and reaches the customer, must meet the requirements of the strict quality control system.

A lot of customers questions mainly concern SkyLight roof windows: Are they comparable to VELUX? VELUX is still a synonym of the highest quality windows, which is also reflected in their price. Is it right to judge only according to this criterion? This clarifies that SkyLight obviously cannot have the same quality. But, is it really so? How should the two cheap brands of roof windows made of plastic - SkyLight and OptiLight - be judged on the basis of quality? To do this, you need to get to know a manufacturer.

Roof window SkyLight at a reasonable price

SkyLight windows are manufactured by Skyfens, a Polish manufacturer of plastic windows that started production in 2000. The company wanted to focus on plastic roof windows that would fit in the low-price segment. To be able to guarantee this, they use already existing technology - common in the plastic facade windows. In this way, the time-consuming and costly acquisition of additional production systems can be minimized. Technology used in PVC frame and steel reinforcement  inside it, ensuree that those windows are relatively massive and therefore have very good stability and robustness. Only in the field of "window fittings" Skyfens had to find a different solution than the one that exists in PVC vertical windows; no further investment was necessary, which could ultimately be reflected in the price. The manufacturer also decided to not invest in production of the additional accessories (there are although other suppliers, that offer basic accessories for SkyLight windows - such as blachout blinds and awning blinds). Thank's to that Skyfens was able to keep the prices low. Another cost factor is always the marketing. SkyLight refrains from doing this and trusts retailers to place the product on the market and the price itself speaks for the product and increases sales accordingly. This strategy works quite well.

Conclusion:

When it comes to SkyLight windows cheap doesn't mean poor quality. The brand stands for plastic windows that have a very good ratio between price and quality. So if you are looking for skylights at a reasonable price (where is no alternative for other types of glass or custom-made products) and fact that there are only limited quantity of accessories that would fit to that window is acceptable for you, Skylight windows are good choice for you. Ten-year warranty and the ability to send spare parts (even if the waiting time is a bit long sometimes) also increases the security that the service life of the skylight is planned for a long time.

Roof window OptiLight at a reasonable price

Optilight windows are being produced by the company named Kronmat, which is a subsidiary of FAKRO. OptiLight windows are basically a response of FAKRO to the increasing demand for cheaper roof windows. Even though FAKRO itself is the world's second largest manufacturer of roof windows, the company is interested in taking some part of cheaper windows market. OptiLight had a bit wider offer from the beginning than SkyLight. In addition to the plastic windows (Optilight TLP) there are also wooden windows (OptiLight B), with permanent ventilation (OptiLight VB) and even - very atypical in the cheap segment - a top-hung skylight (OptiLight VK). The production is of course based on FAKRO technology, for example the plastic roof windows TLP are almost identical to the PTP model of FAKRO, with only a few differences. But those who buy an OptiLight window basically buy FAKRO quality at much lower price. In addition to the price, these windows have another, very big advantage: They are designed in such way that a lot of FAKRO accessories, such as the ARF blackout blind or AMZ awning blind, can also be mounted on the OptiLight windows. Of course, not all products of FAKRO are kompatible with OptiLight and sometimes they are not the cheapest, but the most important thing is that customer an choose between many products to find the perfect one. Thanks to that you can adjust window look to your interior design. Also the manufacturer does not run marketing, which makes the total production costs lower.

Conclusion:

In terms of price, OptiLight is a really interesting product and at the same time it's quality is very good. A big experience and FAKRO technology go with OptiLight. There is also a wide range of accessories that may not be available at as good a price as the windows themselves, but if you save money on skylights then buying only accessories is not such a big cost.
Lower price is possible to obtain, because no special requests are taken by Kronmat - they sell only products and sizes available in the standard offer. To compare - well-known manufacturers such as VELUX, FAKRO or Roto invest a lot to offer as wide range of products as possible and they meet all customers' needs. That causes the costs, but customer can be sure that there's a lot really well designed products to find. A cheap manufacturer can not - and doesn't want to - do that. Strategy of such compans is actually about selling as cheaply as possible. A cheap manufacturer will achieve this in the long term only if the quality of the product is at least satisfactory, otherwise his product will not be able to last long. Our previous customer reviews confirm quite clearly that a good price and good quality go hand in hand when it comes to both SkyLight and OptiLight
