First sloped glazing system to achieve PassivHaus certification

Daylight and Ventilation Solutions (DVS) exclusively represent Lamilux in the U.K. and we are therefore delighted to report that we offer the worlds first PassivHaus certified sloped glazing system.
This article sets out to explain what this certification means and why the PR60 is the roof glazing of choice for PassivHaus projects, as the only certified sloped glazing component. 

Dr Benjamin Krick from the PassivHaus Institute Darmstadt (centre) recently presented Lamilux CEO Dr Heinrich Strunz (left) and Technical Manager Joachim Hessemer with a certificate for the first sloped glazing component compliant with the PassivHaus Standard.

PassivHaus represents one of the most stringent standards in energy efficiency in modern construction. It is regarded as the world’s chief energy efficiency standard for new buildings and building refurbishments. This is because passive houses dispense with separate heating systems and make use of existing energy in buildings to provide heating instead. In order to comply with this requirement, PassivHaus planners rely on high-grade, energy-efficient quality construction materials which retain the maximum possible amount of energy inside buildings and provide an extremely airtight building envelope, thanks to their certified insulation properties. Lamilux has just been provided with conclusive proof that its glass roof structure CI System Glass Architecture PR 60 features such characteristics. This glass and aluminium system has recently been certified by the PassivHaus Institute in Darmstadt, Germany, as the first sloped glazing component suitable for passive houses. The aesthetically pleasing daylight system with its customisable shape achieved top marks and was assigned to the Advanced Component phA category.

Lamilux CI System Glass Architecture PR 60 is the product of consistent further development of the energy-efficient qualities in a thoroughly tried-and-tested glass roof structure, Lamilux CI System Glass Architecture KWS 60. The daylight system manufacturer Lamilux has used this structure in a whole range of sizes in many national and international projects, such as shopping malls, administrative buildings and office complexes. 

The perfect solution for larger area and bespoke roof glazing.

Twice the efficiency thanks to optimised insulation system

In accordance with Passive House requirements, the technical conditions provided in the newly certified system consistently allow glazing to be used which comprises three panes with Argon gas filled cavities. Two of these glass panes feature a low-e coating. The “warm edge” with Super Spacer forms a spacer system. The U value, or heat transmittance coefficient, in the 52mm glazing specification (Ug) is 0.70 W/(m²K) when installed in an inclined position.

Lamilux has developed a new insulation system for posts and rails, consisting of a combined impermeable core which unites the insulation block and the insulation web in a single component. The material used in the system makes the supporting structure twice as energy efficient. The heavy load from the glazing elements is absorbed by the glazing support, aided by glazing fastening bolts, while posts and rails feature very low heat transmittance coefficients of 0.91 W/m²K.

Lamilux have developed a a new insulation system for posts and rails.

Outstanding heat insulation with a UCwi value of 0.82 W/(m²K)

The Passive House Institute in Darmstadt established a UCwi value of 0.82 W/(m²K) for the daylight system as a whole. A good heat transmittance coefficient is one of the main criteria for successful certification and must be under 1.00 W/(m²K) for sloped installation in roofs.

Assessors attach great importance to other aspects when it comes to assuring compliance with Passive House requirements with hygiene playing a significant role. In order to prevent condensation and mould growth, the 12.6°C isothermal line must consistently lie within structures at an outside temperature of -5°C, an indoor temperature of +20°C and a relative humidity of 50 per cent. Lamilux CI System Glass Architecture PR 60 complies with this requirement.

Insulation properties and hygiene requirements play a decisive role in PassivHaus certification.

Heat loss is another factor; this is calculated for the frame system and the ‘warm edge’, and expressed by the coefficient ψopak. The lower this value is, the higher the efficiency class. In the case of Lamilux CI System Glass Architecture PR 60, the coefficient is lower than the maximum value of 0.110 W/(mK) for Passive House classification in the phA – Advanced Component class. 

Glass roofing for energy and cost conscious architects and planners

“With its CI System Glass Architecture PR 60, Lamilux has managed to bring onto the market the first post and rail system in the Sloped Glazing category,” state assessors at the Darmstadt-based Passive House Institute. This provides energy and cost-conscious architects and planners with the first ever glass roof solution which is not only suitable for passive house constructions, but also complies with requirements for the top Passive House efficiency class phA.

Security comes as standard with our glass rooflights

As standard, our aluminium framed glass rooflights offer protection against forced entry – with tested resistance class.

Our rooflights offer burglar resistance - as standard.

Once they have gained access to the flat roof, burglars often try to enter the building by levering open skylights or breaking their glazing.

Comprehensive tests have shown that this method is significantly hampered by our aluminium framed glass rooflights: LINK TO BROCHURE

Our glass skylights belong to resistance class 2. The resistance classes are tested and regulated by European standard DIN V ENV 1627 (identical to BS EN 1627: pedestrian door sets, windows, curtain walling, grilles and shutters. Burglar resistance. Requirements and classification for burglary resistant windows and doors).

Don't make it easy for the burglar!!

Barrel vault rooflight installation at Great Marlow School new sports hall

When architects practice Peter Taylor Associates Limited initially contacted us, our technical rooflight expertise meant that we could offer sound specification advice for their new sports hall project at Great Marlow School in Buckinghamshire. Our continuous barrel vault rooflights were therefore specified for the flat roof to the new sports facility.

Thomas Vale Construction were appointed as the main building contractor for this project and our rooflights formed part of the roofing and cladding sub-contract, which was awarded to Kovara Projects Limited - a leading specialist roofing and cladding contractor.

We worked closely with Kovara right from the early stages, offering detailed information about upstand detailing, tolerances and so on. Once the final rooflight dimensions had been determined our technical department prepared and issued a full set of manufacture drawings for Kovara's approval.

The rooflight order was for the design, manufacture, delivery and installation of 2No. barrel vault rooflights, for an internal upstand dimension of: 1No. @ 1100x9100mm and 1No. @ 1100x33100mm.

Insulated galvanised steel upstand - ready for our rooflight installation

Kovara installed the galvanised steel upstands, which were insulated and weathered to the Kingspan TopDeck flat roofing membrane, ready for our specialist rooflight installers.

Once we had received drawing approval, our state of the art factory commenced rooflight manufacture and materials were delivered to site, ready for installation just 4 weeks later.

Our thermally optimised base track, curved glazing support bars and gable end panels were installed and completed on day one - ready for the glazing panels to be installed.

Completed barrel vault rooflight installation.
By lunch time on day two our 2 man installation team had completed the rooflight installation, and everybody involved was delighted with the result.

A technical note regarding our Continuous Barrel Vault Rooflight system:
Our barrel vault rooflight is the only system with European Technical Approval. Approved with certificate number ETA-09/0347, our continuous rooflight has successfully proven its technical and energy-efficient qualities during these tests. You can read all about what this certification means and why architects, contractors and investors can confidently specify and install our rooflights: The first continuous barrel vault rooflight with European Technical Approval
