The exterior of the Vistas hotel in Benidorm, Spain, has recently been refurbished and given a modern new facade produced in white gel-coated fibreglass (GRP) by Miraplas.
The design, by the Spanish architect Vicente Peidró, used moulded triangular and elliptical GRP architectural shapes. The assembly and construction of the new facade used Crystic Crestomer structural adhesives both for bonding together the moulded GRP sections and bonding the steel frames used to mechanically fix and bond the 22.5m2 GRP sections to vertical steel pillars on the hotel exterior.
The first phase of this hotel refurbishment project was carried out in the Miraplas factory where nine elliptical sections were made from eight individual GRP pieces bonded together with Crestomer structural adhesives; a metal clamping frame was specially designed by Miraplas to hold all the parts in position during bonding.
Scott Bader explain that the most challenging aspect of the architect’s design was the production of the nine large curved triangular and elliptical sections, which proved most cost effective to produce by making separately moulded 5mm thick glass fibre reinforced (GRP) laminate parts and bonding them together. All the GRP parts were produced using an isophthalic resin, three layers of glass matting and an isophthalic gelcoat. Once moulded, the eight separate GRP parts for each triangular section were accurately positioned in the metal clamping frame and then bonded together. Crystic Crestomer 1152PA structural adhesive was applied using a pneumatic gun.
The range of Crystic Crestomer adhesives, manufactured by Scott Bader, have been used in a variety of building and construction applications, such as for cladding panels on bridges, as well as in fibreglass marine applications in both hulls and decks. “Having used Crystic Crestomer adhesives for many years on several other projects, I was able to recommend their use for this project with great confidence that they will provide a guaranteed, reliable long term bonding performance.” stated Mr Jose Manuel Bey Garcia, an independent specialist consultant in RTM processing, who was appointed as the technical advisor on the hotel project. The additional reasons given for using a structural adhesive for this type of application were that bonding helps to significantly reduce the overall weight of the final GRP section, while also offering benefits in production efficiency, particularly using pneumatic application guns where possible for larger sections, in preference to using 380ml cartridge hand guns.
Cobra International is celebrating its 40th year and has commissioned a book that will look at 40 key projects and 40 key people that were integral to the company’s growth. ‘Klaus Simmer and The King Cobra: A breakthrough in surfboard design and production technology’ is an extract article from this book and a breakthrough composites product for Cobra, establishing its presence as a manufacturer of high performance windsurf boards and creating global visibility for the Cobra brand.
