ALUPROF Upgrades Window Performance

Aluminium has the benefit of being lightweight, strong, resistant to corrosion and easy to form into complex shapes, so perfect for production into windows and doors. Over the decades, as thermal insulation of our building infrastructure has increased through regulation, we have seen resin thermal breaks move to ‘roll-in’ polyamide strips amongst other developments.

Aluprof was the first systems company in the world to incorporate ‘aerogel’, a material with exceptional thermal insulation, into the polyamide insulated ‘MB-86’ aluminium window system, which offers specifiers frame insulation down to a staggering frame value, Uf, of just 0.5 W/m2K. A premium product, the ‘MB-86 Aero’ has been specified on a wide range of projects, and now Aluprof have used their design expertise to look at a value added proposition on one of their most popular window systems, the ‘MB-70’.

One of the main driving forces in the fenestration industry today is the ability to reach a net zero carbon target by 2050. In fact in June 2019 the UK became the first major economy in the world to pass a net zero emissions law. The aim is to be carbon neutral in our energy needs in our building stock as well as ensuring that 100% of all building processes will also operate at net zero by 2050. Aluprof continues to stay ahead of the game by offering not only their established range of passive house products, but also through increasing the energy performance of their most popular systems like the ‘MB-70’ aluminium window and door system.

Utilising the know-how gained in the development and supply of the ground breaking ‘MB-86 Aero’, the ‘MB-79N’ utilises the same aluminium profiles as the ‘MB-70’ with the introduction of newly designed and slightly wider hollow polyamide for vent profiles. These structural, lightweight and thermally efficient profiles separate the inside and outside aluminium profiles creating a competitively priced system. The window system is designed for a broad range of applications including fixed, turn, tilt, and tilt-and-slide windows, exterior doors, both in single and double configuration, and shop window-type solutions with entrance doors.

Key to the systems high level performance and value proposition is the use of competitively priced insulation inserts to accompany the polyamide profiles, the ‘MB-79N’ system is available in three variants:

  • The ‘MB-79N E’ the entry level and most economic system.
  • The ‘MB-79N ST’ with a two-component central gasket for opening vents to provide high thermal efficiency.
  • The ‘MB-79N SI’ which provides the highest thermal performance with thermal inserts produced using expanded polystyrene (EPS) and the two-component central gasket.

The ‘MB-79N SI’ can activate an impressive thermal frame value, Uf, of just 0.83 W/m2K, which will offer window system U values down to 0.9 W/m2K and doors of 1.3 W/m2K.

Available in January 2021, the system is available now to be specified on new and refurbishment projects across the UK.Since setting up the Aluprof Office at the Business Design Centre in London, the company has rapidly grown their specification influence in the UK with their high performance architectural aluminium systems.  Further expansion of the companies headquarters in Altrincham now provides specifiers with meeting facilities and an extensive showroom of commercial systems to view.  With overseas growth across Europe spreading into the Middle East and firm roots already in the East of the USA, the company is becoming a global player in facade supply.
