• Thermal insulation: Good insulation values reduce heat loss and lower energy costs.

• Sealing: High-quality seals protect against draughts, moisture and noise.

• Care: Different materials require different levels of care.

• Appearance: The profile influences the appearance and can be designed in many different ways.

• Sustainability: Resource-saving materials and recyclability are becoming increasingly important.

• Price-performance ratio: Quality pays off in the long term through energy savings and durability.

Different variants and their properties

There are various materials with different properties available on the window profile market. An overview of the most common variants shows how they differ in terms of important criteria:

PVC:

This variant impresses with an excellent Uf value of approx. 0.85 W/m²K. PVC windows are particularly easy to maintain as no aftercare is necessary. In terms of appearance, there is a wide variety of colours/designs available. PVC is the most affordable option. Safety aspects are improved by the integrated evoCore® foam core, which provides additional stability. PVC is also environmentally friendly thanks to its high recyclability and resource-saving production. It has a service life of over 40 years. The low-maintenance evoCore® technology is particularly noteworthy.

Aluminium:

Aluminium profiles have a Uf value of around 1.5 W/m²K and are extremely weather-resistant, which means that maintenance requirements are very low. They have a modern, slimline and shiny metallic appearance – a popular choice for contemporary construction projects. The price is in the mid to higher range. Aluminium offers very good mechanical strength and therefore high security. However, aluminium is only recyclable to a limited extent and its production is energy-intensive. Its service life is between 30 and 50 years. Thermally separated frames improve thermal insulation.

Wood:

Wooden windows achieve a Uf value of approx. 0.9 W/m²K and offer a natural, warm look with individual paintability. However, they require more maintenance – regular treatment is necessary. Wood is in the mid-range in terms of price. Security is good, but depends heavily on the type of wood chosen and how well it is maintained. As a renewable raw material, wood is particularly environmentally friendly and biodegradable. With good care, wooden windows can last 30 to 50 years. They score highly with the best natural insulation values, but require continuous maintenance.

Wood-aluminium combination:

This variant combines the advantages of wood (inside) and aluminium (outside). The Uf value is approx. 0.85 W/m²K. Maintenance is low, as the aluminium outer shell protects the wood from the effects of weather. These windows have an elegant, high-quality appearance. They are in the upper price range. In terms of security, they offer impressive resistance thanks to their aluminium cladding. The combination is also environmentally friendly, as sustainable wood is used. The service life is over 40 years. This solution combines natural aesthetics with modern technology.

Explanations:

• Thermal insulation (Uf value): The lower the Uf value, the better the insulating effect of the profile. Pvc and wood-aluminium profiles offer the best values here.

• Maintenance: Pvc profiles require hardly any maintenance, and aluminium is also very low-maintenance. Wood requires regular maintenance to prevent weather damage.

• Appearance: Wood offers a natural, warm look, aluminium windows have a modern and sleek appearance, and pvc is versatile in terms of colour and decor.

• Price: Pvc windows are usually the cheapest, while aluminium and wood-aluminium combinations are the most expensive.

• Security: Aluminium windows offer very good burglary protection thanks to their high strength, while pvc profiles with evoCore® are also stable and secure.

• Environmental aspects: PVC windows from Salamander are particularly sustainable thanks to the use of recycled materials and resource-saving production. Wood is a renewable raw material, while aluminium requires more energy to produce.

• Service life: All materials are durable, with pvc and wood-aluminium profiles often lasting over 40 years.

Window comparison: advantages and disadvantages of different materials

Choosing the right window material has a significant impact on the comfort, energy efficiency and appearance of your home. Each material has specific strengths and challenges that should be carefully considered when making your decision. The following list gives you a clear overview of the most important characteristics of pvc, wood, aluminium and wood-aluminium windows.

PVC:

PVC windows are characterised by very good thermal insulation with a Uf value of approx. 0.85 W/m²K. They require little maintenance, are available in many colours and designs, and are attractively priced. They also perform well in terms of environmental friendliness: they conserve resources and are highly recyclable. Thanks to innovative evoCore® technology, they also offer increased stability and additional insulation performance. Their service life is over 40 years.
Disadvantages include a rather plain appearance and limited design options for very large or special window shapes.

Aluminium:

Aluminium windows have a modern, technical and clean look. They allow for particularly slim frame profiles, which ensure an elegant design. Their mechanical strength is very high, which provides additional security. Maintenance requirements are extremely low, and thermally separated frames improve insulation values.

However, the thermal insulation is weaker in comparison (Uf approx. 1.5 W/m²K), the acquisition costs are higher and the manufacturing process is energy-intensive. Recyclability is also limited. In addition, the cooler, more technical look is not to everyone's taste.

Wood:

Those who prefer a natural, warm look often choose wooden windows. They offer very good thermal insulation with a Uf value of approx. 0.9 W/m²K and are made from a renewable, biodegradable raw material. Wood can be customised with paints or glazes and creates a pleasant living environment.

On the other hand, they require relatively high maintenance and are sensitive to moisture if not adequately protected. The price is in the mid-range. Depending on how well they are maintained, they have a service life of between 30 and 50 years.

Wood-aluminium combination:

This variant combines the best of both worlds: wood creates a cosy look on the inside, while aluminium provides lasting protection from the weather on the outside. This means low maintenance and excellent thermal insulation (Uf approx. 0.85 W/m²K). At the same time, these windows offer high security and a long service life of over 40 years. In addition, the combination of sustainable wood and robust aluminium is particularly durable and environmentally friendly.

Here is a step-by-step guide to selecting the right window profile

Choosing the right window profile is crucial for the energy efficiency, security and appearance of your windows . A structured, well-thought-out process will help you find the right solution for your home and enjoy the long-term benefits of high-quality windows.

Avoiding common mistakes when choosing windows

To benefit from high-quality windows in the long term, it is important to avoid typical mistakes when selecting and evaluating window profiles. These mistakes can not only impair energy efficiency and comfort, but also lead to higher costs and more effort.

• Only looking at the price: Cheap window profiles save money in the short term, but cause higher heating costs in the long term due to poorer insulation values.

• Underestimating maintenance requirements: Wooden windows require regular care and maintenance, while Salamander plastic profiles are particularly easy to care for and low-maintenance.

• Neglecting glazing: The quality of the profile alone does not determine thermal insulation – glazing plays an equally important role in energy efficiency.

• Ignoring sustainability: Materials and production processes should be checked for environmental compatibility in order to conserve resources in the long term.

• Underestimating safety aspects: Window profiles and glazing must also meet high safety requirements to ensure burglary protection.

• Not coordinating design and function: Windows should not only be technically impressive, but also visually match the building and increase living comfort.

FAQ: Frequently asked questions about windows

Do you have questions about windows and window profiles? We have compiled the most important answers for you so that you can make an informed decision and choose the best option for your home.

What type of window do I have?

To determine your window profile, look for the following features:

• Material: Identify whether the window frame is made of pvc, wood or aluminium. Wood usually has a grain, pvc is smooth and often white or laminated, aluminium has a metallic appearance and is slim.

• Construction: Look at the frame thickness and construction. Wood-aluminium windows have wood on the inside and aluminium on the outside.

• Labelling: Window manufacturer information or stickers on the window frame or glass can provide clues.

• Expert advice: If you are unsure, a local expert can help you determine the exact profile.

How are window profiles manufactured?

The manufacturing process depends on the material:

• PVC profiles: In the extrusion process, plastic is melted and pressed through a mould. Salamander, for example, uses the evoCore® foam core made from recycled PET for better stability and insulation.

• Wood profiles: These are sawn, planed and often laminated, then treated (varnished or glazed) for weather protection.

• Aluminium profiles: These are also extruded, often with thermal breaks for better insulation.

• Wood-aluminium profiles: Wood profiles are combined with an aluminium shell on the outside, which is usually attached or clipped on.

How should windows be replaced?

For professional installation, it is advisable to hire certified specialists who will also dispose of the old windows. Replacement usually involves completely replacing the window and includes the following steps:

1. Remove the old window: Remove the window sash and carefully remove the frame from the wall opening.

2. Prepare the opening: Clean and level out any uneven areas.

3. Insert the new window: Insert the window frame so that it fits precisely, align it and fix it in place.

4. Fastening: Securely fix the frame with screws or anchors.

5. Sealing: Seal the inside airtight and the outside rainproof with sealing tapes and foams.

6. Insert sash and glazing: Install and adjust the window sash.

7. Function test: Check opening, closing and tightness.

8. Prepare the living space: Clear the window area, cover furniture and floors, keep access to the window area free – this will ensure that the installation runs smoothly and cleanly.

9. Plan the appointment correctly: Take the weather and time of day into account – on cold days, it is advisable to replace the windows quickly, room by room, to minimise heat loss.
