Mr. Tahvo Sutela from Lasifakta Oy was commissioned to go on-site and control the level of implementation for, among other things, the insulating glass gas fill content. The chosen location was an international airport in Europe.
The quality control of IG gas fill levels was conducted using a Sparklike Laser Portable™ device that enables non-destructive insulating gas analysis for triple and double glazed IGUs, even through coatings and laminated glasses.
Sparklike Laser Portable™ has the whole system integrated into a robust case, allowing easy mobility in factories and on building sites. By using Sparklike’s patented and proprietary technology, device operators are able to deliver tested IG units to the end-user, test already installed units or perform long term testing to their production.
In this case, the contractor is an international construction company that operates in over 10 countries. This well-established company develops and builds apartments, business premises and entire areas. In addition, this contractor is also specialised in demanding infrastructure constructions and paving.
The measurement was done to randomly selected units, including both double and triple glazed IGUs. When analysing customised double glazed IGUs, the gas fill levels did not always fulfil the industry requirements, since the average gas fill concentration varied between 1 percent and 82 percent. To that end, the contractor asked the glass and steel structure suppliers to observe the measurement and control of the units’ insulating gas concentration. The measurement results showed clear repeatability when considering the gas concentration levels for the customised units.
The on-site insulating gas concentration analysis act as a prime example where the contractor has the possibility to verify that the level of implementation had happened according to the original plan. For this example it meant that the measured units should have fulfilled the requested energy efficiency requirements.
In this particular commissioning case, the triple glazed IGUs were laminated with coatings on the 3rd and 5th glass surfaces.
Lasifakta was founded in 2012 by Mr. Tahvo Sutela. The company acts as an independent consulting company for the construction industry and it offers highly competitive and practical solutions such as consulting, training, calculations and problem solving as well as developmental support to their vastly growing domestic and international clientele.
With experience and knowledge gathered from decades of experience in the glass industry, Lasifakta has been working with a countless number of architects, planners and contractors.
The Finnish company Sparklike is the developer and manufacturer of the world’s first and only non-destructive insulating glass gas fill analysers. Non-destructivity along with different device options mean that the device operators are able to deliver tested IG units to the end-user, test already installed units or perform long term automated testing to their production. Also, depending on the device, the insulating glass gas fill analysis can be done for triple or double glazed IGUs, even through coatings and laminated glasses.
Their devices are used daily by world leading IG manufacturers, window and door manufacturers, testing laboratories, building quality inspectors and construction consultants. All Sparklike devices™ are based on their patented and proprietary technology.
