One of the varieties of an interior or input threshold is the gill threshold. It has a fairly wide application, as it approaches any type of door, its installation on any canvas has no restrictions. Used even for input aluminum structures.
The threshold-hyliotin is a metal structure, a P-shaped form that has a seal on a spring. The design of the threshold is simple and reliable, can withstand up to 250 opening/closing cycles. There is also the possibility of fitting it under the required size, by cutting. There is, of course, a spoon of tar — the lower part of the canvas for this threshold should be properly processed under the groove. The threshold seal begins to work as soon as the door closes. This allows you to carry out a plastic rotary head installed on the threshold. The seal on this threshold costs rubber. Its main advantage is that the course of a rubber seal can be in the range of about 13 mm, both from above and below. In general, the gill threshold in many ways increases the sound insulation qualities of the door leaf. And also prevents the appearance of various smells from the outside of the room into which the door with the threshold-gyliota leads.
