Insulated Retractable glass roofs – Insulated - Test results

Norway 's Building Research Institute in Trondheim has carried out extensive tests of Bentech´s insulated retractable roof system.
The tests confirm the excellent results noted by our customers in practical experience - that our roofs are both watertight and airtight.
Watertightness
The roof is just as tight when it is inclined at 5 degrees as it is at 35 degrees. It has even been recommended for use in harsh environments, such those experienced along the Norwegian Atlantic coast.
Airtightness
Airtightness for windows is defined in the class 4 regulations of the NS-EN 12207 standard. Bentech´s insulated retractable roof meets these requirements.
Tightness guarantee
Bentech is the only manufacturer in the world which guarantees that their retractable glass roof is completely waterproof down to an inclination of as little as 3 degrees.
