EEAS sill for plastic lift-slide doors is being further developed for other profile houses

Comfortable sliding and with excellent performance in all areas

At the end of 2020, we reported in this magazine about the development of the EEAS sill, by Venster Techniek from Zelhem. The EEAS sill was developed from a market demand, as a variant of the proven EEAL sill for plastic window frames, this time for use with Gealan's plastic Lift&Slide doors. Thomas Keizer of Venster Techniek said at the time, "Especially for Gealan's S9000 series, we have now developed the EEAS sill for plastic frames, completely adapted to Gealan's S9000 profile. The sill is 190 mm wide and fits seamlessly to the frame thanks to special shims." Gealan thus became the first profile house for which the famous fiberglass-reinforced sill for lift-slide doors is available. At the time, it was announced that the EEAS sill would also be developed for other profile houses. Window Technology kept its word; we talk about it with Thomas Keizer and Herben Heino.

Extensively tested

"Together with HEBO window frames and Ventana Deutschland, extensive tests were conducted with the EEAS sill for Gealan, with success," Thomas opens the conversation. "Ventana has thus embraced the EEAS sill and applies it optionally to the GEALAN lift-slide doors they manufacture." 

Herben adds: "The EEAS sill for GEALAN is completely finished and sits alongside the other products in the ordering system. The technology is fully translatable to other profile houses. Talks on this are now underway with other brands. As soon as a profile house says "yes," Window Technology is ready to work out the details and test the EAAS sill. We then invest in the moulds, we develop the right connection blocks. So it takes a lot of 3D prototyping (print work in-house), the necessary drawing work is done and we test everything." 

The benefits come within everyone's reach

Thomas continues: "Everyone will soon be able to enjoy the many advantages of the fiberglass-reinforced EEAS sill. In internal tests, the sill has already proven itself with extremely high values in terms of wind and water tightness. We have added a nice dewatering principle in the design. Tests will soon take place internally at GEALAN as well, to officially validate everything. The profile house will then adopt the test values in its own technical documentation."

Looking at the advantages of the EEAL sills (and therefore also the EEAS sill), we see that they comply with the Building Code. Also striking is the enormous stability. Herben explains: "These good properties come from the fact that this sill is made from fiberglass-reinforced material. As standard, it is produced in a Stone-Look, which in terms of appearance is co-produced in the production process." 

Thomas: "That makes the sill extremely stable, good for comfortable sliding action. The sills are concept specifically manufactured in-house so that coupling posts and profiles are not a problem, but integrate neatly into the neutral."

Perfect fit

The sill has the same width as the plastic profile, so the production of the frame is not hindered by a protruding sill. "There are centering points mounted in the sill to prevent twisting of the style relative to the sill," Thomas explains. "The EEAL sills for plastic window frames that Venster Techniek develops for profile houses are custom-made at various points. These custom sills are lightweight. The coupling posts and profiles are concept-specific and are integrated into the neut. Furthermore, the sill is super insulating. The sill is fixed under the frame, without protruding parts. We produce up to a length of as much as 7 meters. The EEAS sill for lift-slide doors is very stable for the above reasons." 

Thus, there is a perfect fit. Window Technology constantly innovates to ensure optimal performance.
