Series: BI48-S

The BI48-S differs only aesthetically on the outside, in the sense that we do not have the classic "Folder and Pressor" but a joint of just 18 mm. Also in this series the news are many. Structurally, its peculiarity is that the Uprights and Crossbeams are the same as those used in the BI48-F, therefore reducing the purchase of other profiles needed for the transition from one series to another.

We gave up the classic "butterfly" to anchor the glass to the lattice of the structure both mainly for the cost and for the impractical and complicated assembly in cutting the polyamide into countless pieces of about 300 mm to be fitted piece by piece after screwing the classic "Butterfly".

Not to mention the glass, in some systems the "Butterfly" has direct clamping contact on the glass, concentrating compressive forces in very small square mm.

Others have glued a stainless steel profile to the perimeter, excellent performance very true, the point is that the costs reach the stars but the fact that the same "Butterfly" remains and the same job of cutting countless pieces of Spacer, bringing the costs of materials used and labor too high.

BI SYSTEMS srls has designed and patented an extruded aluminum profile to be then cut, designed to build an accessory to anchor the glass to the lattice of the structure. (BA-158F).

For anchoring the glass on the facade, an extruded aluminum profile (BA-28ST) is cut to size on the glass perimeter and with 4 simple screws the four corners are closed and all glued to the same glass with structural silicone making it easy, fast and safe.

The costs of making it all are so negligible that they are incredible.

In the event that the glass breaks, the costs will be more for the glass than for the door that supports the glass, therefore a great saving in many respects.

In this case, the Spacer has been designed so that it completely wraps the central part of the Upright, fitting into the groove of the presser tightening and is cut along the entire length of both the Upright and the crosspiece, therefore not in countless pieces and at the same time assembles in the workshop and not like the others on the construction site.

In this way there is a thermal insulation and our accessory has no direct contact with the upright, because the spacer has already been inserted.

It has two EPDM fins, facing outwards so that when the door is anchored it closes the hollow of the assembly and places a barrier against noise and any water that can infiltrate and a further acoustic seal.

On the outside and anchored to the glass door, there is a fin gasket (BA-17ST) which by assembling the doors in series, as in the figures shown, forms an overlap of the same, forming a thermal barrier too. , acoustics, air, water and finally hiding the glass anchor screws.

Alternatively, you can opt for a sealing with low modulus silicone, obtaining excellent results if a glass roof cover is to be made.
