TYPE WS structural window installation profiles (windowsill profiles) are used for fixing the lower part of the window or door and adds additional insulation. The reduced loss at the bottom of the window reduces cold thermal bridges and prevents the appearance of moisture and mold. The cold bridge occurs when a building's insulation is interrupted or less effective at certain points in the building envelope. TYPE WS Profiles can be milled according to the profile of the window/door frame (milling options are evaluated separately according to the width of the window/door profiles). Profiles are sold in units, the standard length is 2750 mm.
