Wind & Water Tightness

Wind and water tightness are two of the most important elements determining the quality and comfort level of the systems installed. Reynaers aluminium windows and doors are developed and tested to withstand different levels of water and wind tightness. Our aluminium systems are meticulously tested in our state-of-the-art test centre.

Firm Sealing

Reynaers aluminum windows and doors are equipped with high quality EPDM-gaskets that keep out air and water, during the complete lifetime of the elements. For our aluminium windows, our systems are equipped with a central gasket, guaranteeing the water barrier and an acoustic gasket on the inside, increasing the acoustic performance. Our aluminium doors have dedicated gaskets on both the inside and outside, to ensure air and water tightness. 

Water Drainage

Besides the presence of a water barrier, water tightness is also obtained by good water drainage.  For all systems (windows, doors, sliding doors, curtain walls etc.) this water drainage is crucial and requires a good concept.   
 
The water enters the system before it is led outwards through special drainage slots, avoiding the accumulation of water. These slots are covered with drainage caps. Another option is to attach an extra profile, resulting in an invisible drainage system.
