It has been specially developed for SOFTLINE 82 NL from VEKA: the DTS low-relief sill with CE conformity from Innodeen. "The sill enhances the appearance of the frame, has a high wind and water tightness and is easy for frame manufacturers to process," says Bart Eeftink, construction technical consultant at Innodeen.
Eeftink was involved in the development of the system from the beginning. "There is increasing demand in the market for a DTS sill with struts, combined with high wind and water tightness. There is also the demand for CE conformity. We wanted to meet both demands by developing a new sill type for the SOFTLINE 82 NL profile series and combining it with CE conformity. We did this in cooperation with VEKA."
Aesthetic and practical benefits
The first low-relief sill with CE conformity for VEKA SOFTLINE 82 NL clearly distinguishes itself from universal sill systems. "This sill with struts makes it possible to create the appearance of a traditional window frame in combination with SOFTLINE 82 NL." In processing, the sill also offers practical advantages. "With some universal systems, special processing must first take place on the plastic styles before the frame can be connected to the sill. Because this system has struts, this is not necessary. You always have a flush connection. The style profiles only need to be cut straight, after which they can be mounted on the neuts."
High wind and water resistance
Depending on the project and location, window frames have specific requirements for wind and water tightness. This is another area where the sill stands out; it is suitable for situations where high demands are made. "For the inward-turning door, the sill achieved 600 Pascal. This means that at a wind pressure of 600 Pascal and sprinkling, the system is and remains tight. For the outward-turning door, it is 350 Pascal."
In accordance with the Building Code
With wind and watertightness in mind, some finesses were applied. "The sill is equipped with a dewatering channel to drain through water. The variant for outward-turning doors also has a double sealing stop. Here a plastic lath is placed at the bottom of the hinged part, keeping the step of the sill as low as possible. Thus, accessibility remains guaranteed."
The variant for inward-turning doors has a step of 19 mm. "This is in accordance with the Building Code, which states that for the entrance door to the house, the step from inside to outside should be a maximum of 20 mm. For outward-turning doors, despite the double stop, the sill has a step of only 30 mm."
Smooth cooperation
In the process from development to CE marking, Eeftink was in constant contact with VEKA's technical people. "We discussed and optimized the initial design. Then a test sill was made on which a pre-test was performed in combination with a VEKA test frame. Perfect that we were able to do this at VEKA in Sendenhorst, Germany, because it revealed important points for improvement. The second test sill made afterwards was tested and approved by SKG. VEKA's technical advisor was there to adjust the frame. A good collaboration; we are very satisfied with it."
Durable sill
In terms of sustainability, too, the sill is an excellent fit for SOFTLINE 82 EN. "The DTS sill system has been awarded the Silver Level Cradle to Cradle (C2C) certificate. The sill is made entirely of recycled material and is itself completely reusable. Milling waste created during profiling is reused in the production process."
New name
The sill is a product of Innodeen in Lochem, the company that until recently was called Kreunen Kunststoffen. "Our sills product group was referred to as DTS Sills, a name that was often perceived as the company name. In addition to the well-known sills, we also develop and produce other plastic applications for the construction, civil, concrete and food industries, among others. In order to better highlight the diversity and to have an internationally recognizable name, Innodeen was chosen as the new name. A reference to the innovative nature of the company and to the various plastics we use, such as HOLODEEN and DURODEEN."
