The real questions are:
Does it solve a problem?
Is it serviceable?
How is it going to look in ten years?

BOAVISTA is the brand of window frames of FWD. It is the first fully manufactured in FIBERGLASS, which is considered by leading experts as ““Material of the future””! We exist based on a strong set of core values that we defend and apply in everything we do, from our everyday life, to every single construction created:


Aimed for the final consumer, architects and construction, promoters BOAVISTA Windows are the ideal choice to those looking for high thermal and acoustic performance, and take great comfort in using an environmentally responsible product that has a reduced ecological footprint.

The right choice of window for a new project, or even for a rehabilitation one, contributes decisively for a balanced final aesthetic. This will also affect the interior. environment.

For us, the future of construction will be guided by two vectors: the superior quality of materials and the environmental protection they provide. We want to be part of this future; with you!



  • Sand is the main raw material for fiberglass, this is widely available in Nature;
  • Pultrusion has a energetically low demanding production process;
  • The profiles production and windows manufacturing processes produce very little waste;
  • The profiles don’t require any kind of special transportation;
  • The material life cycle is a very long one. There are those who call it "the 100 year window"!;
  • The fiberglass windows have a high thermal and acoustic efficiency, allowing energy savings throughout their life cycle.


Fiberglass is the common name for GRPs – glass reinforced plastics; that is a composite material, which means, a material composed by two or more components with different physical and chemical properties combined to result in a new material with excellent features.

With the use of composite materials, one just needs to choose the right components and it is possible to create a product resistant to chemical corrosion and high temperatures or with excellent insulating properties and endurance, it depends on the specific needs.

For this motive, during the last decades, composite materials (including fiberglass) have been gaining ground in virtually every sector (from furniture to structures, marine industry, etc.) and are now more commonly being used in the construction industry.

GRPs are a material with a high tensile, flexural, compressive strength and impact resistance often used in structural applications.

Fiberglass is a light and non-conductive material, used also as an insulator. It allows large design flexibility as it enables the molding of complex parts, big or small, seamlessly and with great functional and aesthetic value.

It does not rust and presents exceptional resistance to highly aggressive environments in comparison to conventional materials. This chemical resistance of GRP’s is determined by the resin and laminated construction used.

While constant section profiles are produced by pultrusion, molding produces the larger and more complex parts. This process, used for low volume production, is mainly used in the manufacture of boats, surfboards, furniture and parts for the automotive and aeronautics industry.

Whatever the manufacture method used, the final result will always be a product with low maintenance costs due to the chemical inertness and high weather resistance inherent to the material.


  • Low thermal conductivity;
  • High dimensional stability;
  • Able to maintain its properties either in very high or very low temperatures;
  • Excellent mechanical properties;
  • Excellent corrosion resistance;
  • It does not brittle at low temperatures.


The fiberglass profiles used in all BOAVISTA windows are produced with POLTRUSION technology.

BOAVISTA Windows are completely manufactured in fiberglass, a material that combines a high mechanical resistance (allowing large spans) with a high efficiency in thermal and acoustic control. They also have a very high durability, not being affected by harsh environments such as a marine environment.

By using pultrusion as the manufacturing process of BOAVISTA Windows, we ensure that the environmental costs of their production are extremely low.

BOAVISTA windows are finished with high strength polyurethane paint in any desired color.


When compared with other materials commonly used in the manufacture of windows applied in construction, the GRPs are those who have the best features.

Any pultruded product in fiberglass consumes less natural resources and energy and it is more favorable in terms of emissions than a similar product made in other materials.

BOAVISTA supports the Dalila Gonçalves Exhibition at the KubikGallery

BOAVISTA is backing up the KUBIKGALLLERY at the “Procedere é Processo” exhibition from the artist Dalila Gonçalves, considered by Time Out – Porto magazine as the exhibition of the month of September.

This exhibition presents us with a set of Works that result from a experimental game that looks to test the permeability between materials and the process of artistic practice with the living of everyday life.

Using video, photography and installation as tools, the artist designs objects that don’t always imply the real transformation of things, in many cases materializing themselves by the simple unexpected, ironic, absurd or metaphoric use of the material. By the subtle information that is used, by the proper nature of the materials or by the simple modus operandi, it juggles with its “perception” and the idea of “evidence”. It’s on these awkward moments, this border between physical reality and fiction, that the feel and thinking mechanisms are activated, thus giving meaning to the artistic object.

Dalila Gonçalves was born in 1982 in Castelo de Paiva (Portugal). Has a degree in Fine Arts – Painting from the Faculdade de Belas Artes da Universidade do Porto (2005). A master’s degree in Visual Arts Teaching from the FBAUP and FPCEUP (2009). In 2008 was selected for the Gulbenkian Artistic Creation and Creativity Program Photography Course. Worked between 2010 and 2011 in Ignasi Aballí’s atelier (Barcelona) with a scholarship from the Inov-art program (Portuguese Ministery of Culture). Currently receiving a PhD on Art and Design at Faculty of Fine Arts of Porto University (FBAUP).

Inauguration will be on the 21st of September, and it will be on display till de 27th of October 2012.
