New anti-algae slat with hail certificate !

T&A has contacted an independent laboratory in Switzerland to determine the hail resistance of its slats. Very precise spheres of ice are launched onto the profiles to find the weak spots.
There are 3 criteria: waterproofness, mechanical resistance and aesthetic preservation after impact. The tests show that the T&A profile remains perfectly intact after impact of ø3cm hailstones. The mechanical resistance goes up to ø5cm which is even bigger than a golf ball!
