BB80 Alu - an aluminium and PVC hybrid<\/strong><\/h5>\n

BB80 Alu is a hybrid window system that combines two materials in a single construction. On both the outside and the inside, aluminium shells (an ALU-PVC-ALU structure) give the window the look, slimness and durability of aluminium joinery on both faces. At its heart works a PVC core that delivers outstanding thermal insulation \u2014 this is what lets the window reach passive-house performance.
\nIn this construction, the aluminium profiles replace the steel reinforcements normally used in PVC windows, making the window lighter and production simpler and faster. It is deliberately positioned as an alternative to aluminium windows for those who want their look but expect better thermal performance at a lower price. The finished windows are fully recyclable and work with sliding, door and fa\u00e7ade systems.<\/p>\n

HY BB80 ALU? KEY ADVANTAGES<\/strong><\/h5>\n

The look of aluminium, a price closer to PVC<\/strong>
\nThe aluminium clads give the look and prestige of an aluminium window, while the PVC core lowers the cost compared with a full aluminium construction. Premium design without the premium price.
\nPassive-house thermal performance<\/strong>
\nA Uw coefficient from as low as 0.73 W\/m\u00b2K places BB80 Alu among energy-efficient and passive windows - lower heating bills and real thermal comfort.
\nA lighter, modern construction<\/strong>
\nAluminium profiles replace steel reinforcements, so the window is lighter while keeping its rigidity. This makes larger glazing and installation easier.
\nLarge glazing<\/strong>
\nA window sash up to 2500 mm high and up to 130 kg (even more with bonded glazing) allows for large, modern glazing that lets in maximum light.
\nFull tightness and three-component gaskets<\/strong>
\nThree-component gaskets, in a 2- or 3-gasket version, protect against wind, rain and noise. High tightness classes (air permeability class 4, watertightness up to E1950).
\nEkologia i recykling<\/strong>

ALUMINIUM LOOKS, NO COMPROMISE<\/strong><\/h5>\n

BB80 Alu<\/strong>\u00a0BB80 Alu is designed so that, at first glance, it is indistinguishable from a full aluminium window \u2014 and the details prove it.<\/p>\n

Invisible 45\u00b0 corner welds \u2014 clean, elegant joints instead of the welds typical of PVC.
\nClassic and fully flush versions - the flush version conceals the sash within the frame for a uniform, modern surface.
\nA glazing bead that imitates the 90\u00b0-cut aluminium clip - exactly as in aluminium joinery.
\nClassic or concealed hinges and visible or hidden hardware - full control over the aesthetics.
\nColours from the Color Collection 2 palette - RAL colours, textures and wood-effect decors.
\nThe result: a window that looks like aluminium and suits modern, minimalist architecture, while maintaining thermal performance that full aluminium usually can\u2019t match.<\/p>\n

 <\/p>\n

<\/h5>\n
WHO IT'S FOR \u2014 APPLICATIONS<\/strong><\/h5>\n

Modern detached houses - large glazing and an aluminium look without losing energy efficiency.
\nDevelopers building energy-efficient and passive homes - a low Uw from 0.73 W\/m\u00b2K supports the passive standard.
\nThose looking for an alternative to aluminium windows - the same design, a lower price and better thermal performance.
\nProjects with large windows and doors - sashes up to 130 kg and compatibility with sliding\/fa\u00e7ade systems.
\nMinimalist architecture - the flush version and concealed sash for uniform surfaces.<\/p>\n
