Complete set of interior doors is not complete without appropriate fittings. Along with handles, chains, eyes and various inserts, manufacturers attach loops to the kits. Perhaps this is the main element of the door kit, on which the quality of fixing the leaf in the opening depends. Traditional hinge models are usually used, the device of which involves insertion into an array - a special groove is formed for this.
The development of technological methods for the manufacture and installation of doors has led to the development of a "butterfly" hinge, which does not require a tie-in. The new hardware has other fundamental differences, which are characterized by both pluses and minuses. Proper installation will preserve the advantages and minimize the disadvantages of the finished door structure.
Design Features
The main difference between butterfly hinges, which also affects the features of installation with further operation, is the fit to the door surface. Such fittings do not require the creation of grooves for insertion - the loop card is superimposed on the surface and also twisted. The fastening sides are designed so that one part, when the doors are closed, is built intodifferent, which is the reason for the name "butterfly". The number of self-tapping screws varies depending on the set, but on average corresponds to the classic sets of mortise hinges.
Installation process
To understand how to install the butterfly loop correctly, you need to take a closer look at its design. The installation technology of overhead models, as noted above, is due to the specifics of their work. The absence of the need to form grooves is a significant advantage of such loops, otherwise the installation process follows the usual method.
First, the location of the loops is marked. It is advisable to apply them with the inside, and then fix the drilling points. The gap from the edges of the web should be at least 200 mm - the average indentation not only for the "butterfly" hinge, but also for the usual versions of this fitting. Then neat holes are made for self-tapping screws, which are usually supplied with hinges. The final touch will be the direct screwing of the sides of the "butterfly" to the door frame and leaf.
Installation details
The outward ease of the installation process and in particular the absence of the need to create niches in the array captivates many. But all the advantages that butterfly door hinges have end there. Only after installation can one appreciate how ambiguous such fittings are.
The point is to get the right effect from using loops without a punchpossible only if the installation is flawless. Compared to traditional models, "butterflies" do not provide a wide field for refinement. Firstly, the sides must fold perfectly, otherwise an unevenness will form - the door will spring or, at least, not fit snugly. Secondly, you will have to put up with a small gap, which, naturally, is formed from protruding looped cards. And one more unpleasant moment, which also characterizes the "butterfly" door hinges and the design without a tie-in as such, is the impossibility of removing the door leaf without unscrewing the screws.
How to fix errors?
It is impossible to get rid of all the listed consequences of using such original hinges, but it is possible to minimize their impact on ease of use. Among the most important tasks that the masters solve during the installation of butterfly loops is to ensure uniformity when the cards converge. Usually inconsistencies are eliminated by creating linings. For this, cardboard, thin chips, paper and similar material are used - it is necessary to enclose in the part opposite to the side that does not overlap.
Besides, hinges for butterfly doors, due to structural features, do not provide a high degree of reliability. Of course, it all depends on the product, but they lose significantly to mortise-type hinges. Therefore, it is important to perform the fixation with screws as efficiently as possible - the absence of peeking hats and slopes during insertion will be reflected in reliability.
Another questionable feature is the locationself-tapping screws on the map. On one side they are closely spaced, and on the other side they are far apart from each other. The configuration cannot be corrected, but the possibility of damage to the door to which the butterfly hinges are planned can be excluded. Installation is carried out on solid and secure areas - i.e. suitable for screwing.
Which doors fit?
It is possible to determine the segment of optimally suitable doors for the design of butterfly hinges based on the strength of the fastening. This nuance has already been considered, and it is quite natural that it is undesirable to supplement heavy models with such systems. Still, the operation of inserting into the array adds reliability to the fastening, while external fixation without insurance seems very risky when mounting a 40-kilogram web.
Butterfly hinges, on the other hand, with smooth and clean installation, are ideal for lightweight, effortless doors. In particular, representatives of the veneered category are combined with "butterflies" not only technically, but also visually. Models made of solid wood are recommended to be equipped with mortise fittings - the complexity of installation is compensated by their reliability.
Decorative effect
The overlay fastening system of the "butterfly" loop is also due to aesthetic considerations. No matter how neat the tie-in is, the master will not be able to maintain the integrity and decorative completeness of the door to the same extent. Bypassing all the difficulties of installing such loops, you canachieve unsurpassed results. Since there is no need to interfere with the moody laminate surface, butterfly hinged doors should be considered the best option for living rooms, bedrooms, offices and other rooms where stylistic harmony is important.
Result
Fixed hinges can hardly be called the best choice for amateurs and beginners who can count on simple installation without creating a tie-in. Some risks are eliminated, but others arise. Nevertheless - subject to strict marking and verified convergence of the cards - butterfly hinges will provide the result in the form of aesthetic interior doors with an original mounting configuration.
Finally, it is worth turning to mortise models, which still remain the most popular solution for fixing doors. This choice is worth making if you need a solid and reliable design, however, you will have to sacrifice decorativeness. Nevertheless, the clumsy principle of introducing such loops is incomparable with a delicate overlay without damaging the wood.
