The greenEvolution and BluEvolution window profiles are two Salamander systems that are very popular with Fenbro customers. Although they may appear similar, they differ considerably in the details. In this article, we will clear up all the differences between these two profiles once and for all – so that you can see exactly how they compare.
The history of the Salamander window brand
Some people may associate the Salamander brand with shoes – and rightly so! Salamander windows and Salamander shoes share the same origins in Berlin. The brand was founded in the city towards the end of the 19th century. However, the production of window profiles did not begin until 1973. The window division was spun off in the eventful year of 2004. Today, the footwear and window divisions are two completely separate companies.
The BluEvolution system: exceptionally strong
The BluEvolution range was introduced by Salamander in 2009. It is a robust and reliable profile system that offers exceptional rigidity and excellent insulation properties. It also meets the demands of modern construction: thanks to its internal reinforcement, it is suitable for large glazed areas, can be combined with a wide range of glazing options and provides outstanding thermal and acoustic insulation.
Could it be described as the ultimate uPVC window system? It comes very close – so, essentially, yes. Fenbro offers the Flex version of the Salamander BluEvolution 82 system. The top-of-the-range Salamander BluEvolution 92 is also available.
Technical features of the Salamander BluEvolution profile
The system was primarily designed to provide maximum energy efficiency and meet the requirements of passive house construction. This profile features six chambers in both the frame and sash, helping to limit heat transfer. It also provides excellent stability and resistance to significant structural deflection.
Thermal bridges are considerably reduced thanks to a specially designed gasket arrangement. The system is most commonly used in its centre-seal version. This construction allows the profile to achieve a low heat transfer coefficient. When combined with high-performance, gas-filled triple glazing, it delivers optimised window performance for energy-efficient buildings. The appropriate frame depth also provides a wider choice of glazing options for enhanced acoustic and thermal insulation.
From a mechanical perspective, the system keeps its components inside a special dry chamber, physically protecting moving parts against moisture. This extends their lifespan by preventing corrosion. Torsional rigidity is ensured by thick-walled, fully enclosed galvanised steel reinforcements, which easily distribute the weight of heavy glazing and provide robust protection against burglary.
In terms of acoustic performance, the profile’s increased frame mass and triple-gasket arrangement in the centre-seal version provide excellent protection against external noise. Visually, its slim contours allow more daylight into the room and maximise passive solar heat gain. The system also features a characteristically simple, flat appearance that fits seamlessly into minimalist architectural designs.
The standard BluEvolution system has an installation depth of 82 mm and can accommodate glazing units up to 50 mm thick. For more demanding applications, a 92 mm version is also available, capable of accommodating glazing units up to 60 mm thick.
Salamander BluEvolution 82
Applications of the BluEvolution system with example projects
The system works particularly well in modern buildings, especially those designed in a contemporary architectural style – minimalist in appearance but demanding in terms of energy performance. The choice between the 82 mm and 92 mm versions depends on the customer’s requirements regarding energy efficiency and burglary protection.
For example, the BluEvolution 82 system in matt black was used for this home renovation project in Galway, which included windows in a wide variety of shapes. Despite the considerable size of the building, the windows provide excellent insulation while creating a distinctive and elegant appearance.
This house in Roscommon, on the other hand, required white windows to brighten up the façade. The solution chosen provides the homeowners with exceptional peace and quiet despite the property being located on a busy road. The Uw values achieved with triple glazing also help to improve comfort and reduce energy consumption.
In this detached house in Longford, the slim frames help to create bright interiors. The generous glazed areas fill the property with natural light and give it a greater sense of openness. The thermal insulation values achieved bring the property close to passive house standards.
The greenEvolution system: modern and future-ready
On the other hand, we have Salamander’s greenEvolution range – a considerably newer and more modern solution. The range was introduced in 2021 and focuses on current developments not only in the window industry but also in the raw materials market. It is primarily promoted as the ideal solution for renovation projects. Fenbro offers windows made using the greenEvolution Flex profile.
Technical features of the Salamander greenEvolution profile
The greenEvolution range is distinguished by its high proportion of recycled material – up to 50% in the profile core. The aim is to make the profile lightweight, environmentally friendly and cost-effective.
This window system was developed as an extremely versatile and structurally optimised platform, bridging the gap between standard windows for conventional residential buildings and the performance requirements of passive houses. It is an excellent choice for informed homeowners.
The profile features a five- or six-chamber construction with steel reinforcement. This configuration maximises rigidity and limits deflection under high wind loads, providing excellent structural performance. The thermal performance of the greenEvolution system is supported by its carefully designed sealing system. It is suitable for both modern double and triple glazing. The slim greenEvolution system can accommodate thinner glazing units than BluEvolution.
In addition to the rebate-seal version, which uses two gaskets, a centre-seal version with a total of three gaskets is also available. This creates a continuous central barrier that offers excellent resistance to driving rain while maximising airtightness and acoustic insulation. The internal dry chamber, a feature well known from Salamander windows, provides additional protection for the hardware against adverse weather conditions.
Salamander greenEvolution Flex 3D
Applications of the Salamander greenEvolution system with example projects
Salamander promotes greenEvolution as the first-choice profile for upgrading and renovating properties – and the system is indeed frequently used for this purpose. However, customers also choose it for new-build projects. Below are a few examples of how it can be used.
During this extensive property renovation in Clare, greenEvolution Flex 3D profiles were chosen because of their lightweight construction. The distinctive, large glazed wall allows plenty of natural light into the room while also providing excellent thermal insulation. The dark green profile colour allows the house to blend seamlessly into its surroundings.
This renovation project in Louth required exceptionally strong windows that would provide a high level of protection and security. Anthracite grey was the perfect colour choice for this property. The windows are triple-glazed and, in addition to excellent thermal insulation values, feature additional security equipment.
This lightweight property in Mecklenburg-Western Pomerania was fitted with windows featuring glazing bars, creating a distinctive and traditional character. The lightweight, bright profiles with double glazing give the façade a cheerful appearance. Double glazing also helps to keep the window sashes relatively light.
