Laminated glass is a safety glass that uses one or more layers of PVB film (polyvinyl butyral) or SGP between two or more pieces of glass. It is made under a special process and is combined into a whole through high temperature and high pressure within a certain period of time. Longlass Laminated Glass Advantages: 1. We have high class dust-free constant temperature and humidity laminating production line. 2. We are the approved processor by SentryGlass 3. Our products meet the requirements of BS EN12600:2002 Class 1 (C) 1 ,and ANSI Z97.1-2015 Class A ,type 4. An impact perfbimance test for materials in accordance with BS EN12600:2002 has been performed on the four given samples. The performance classification of the all test samples is Classification 1 (C) 1. Performance Test Sample:5mm tempered glass + 1.14 PVB + 5mm tempered glass Impact Test: In accordance with Clause 5.1 of ANSI Z97.1-2015 Type 4 Thermal Test: In accordance with Clause 5.3 of ANSI Z97.1-2015 The distinguish between PVB & SGP: 1.The shear modulus of SGP is 50 times of that of PVB. 2.The Tear strength of SGP is 5 times of that of PVB. 3.The bearing capacity of SGP is 2 times of that of PVB. 4. The bending of SGP is only 1/4 of that of PVB. In a word, SGP has better performance than PVB, and it's widely applied in glass path, glass ceiling, glass floor, Stair Treads,etc. Longlass Laminated Glass Features Energy saving When sunlight directly shines on a piece of colorless laminated glass, the PVB interlayer film can absorb most of the heat and only radiate a part of the heat back indoors, making the indoor and outdoor heat difficult to conduct, reducing heat energy consumption, thereby maintaining indoor temperature and saving air conditioning Energy consumption. Security it can withstand the penetration of accidental impact. Once the glass is damaged, its fragments will still stick together with the intermediate film, which can avoid personal or property damage caused by the glass falling, and the whole piece of glass remains intact and can continue to withstand impact, wind and rain Sound insulation The interlayer film has the function of blocking sound waves, so that the laminated glass can effectively control the transmission of sound and play a good sound insulation effect. Noise reduction In the process of sound wave transmission, the glass on both sides of the film is reflected back and forth, and is attenuated and absorbed by the soft film. Generally, the noise can be reduced by 30-40 dB. The thicker the film, the better the noise reduction effect. Decorative effect The laminated glass can be sandwiched with various patterns, which can achieve the decorative effect, and there are also decorative effects such as ice glass. UV resistance The interlayer film has the function of filtering ultraviolet rays; the special PVB film can make laminated glass weaken the transmission of sunlight, effectively block ultraviolet rays, reduce the fading of indoor fabrics. The color PVB interlayer film has different light transmittance, and can control the ultraviolet and heat gain as needed. It will not block the penetration of visible light .

A striking, sculptural effect with the Flight 50 Internal Metal Staircase is achieved through graduated winders. This creates the dramatic curved steel stringers on this staircase, providing an interesting visual aspect and a very comfortable staircase. The solid oak treads have glass risers to conform with UK building regulations for staircases. (requires no gap greater than 100mm)

TG-Studio tackled the brief to create a light and bright space and make the most of the unusual layout by designing a new central staircase, which links the six half-levels of the building. A minimalist design with glass balustrades and pale wood treads connects the upper three floors consisting of three bedrooms and two bathrooms with the lower floors dedicated to living, cooking and dining. The staircase was designed as a focal point, one you see from every room in the house. It’s clean, angular lines add a sculptural element, set off by the minimalist interior of the house. The use of glass allows natural light to flood the whole house, a feature that was central to the brief of the Norwegian owner. Photography: Philip Vile

The floating staircase creates a sense of openness among the rooms, creating a flow of light and connection between the rooms.

If there is a God of architecture he was smiling when this large oceanfront contemporary home was conceived in built. Located in Treasure Island, The Sand Castle Capital of the world, our modern, majestic masterpiece is a turtle friendly beacon of beauty and brilliance. This award-winning home design includes a three-story glass staircase, six sets of folding glass window walls to the ocean, custom artistic lighting and custom cabinetry and millwork galore. What an inspiration it has been for JS. Company to be selected to build this exceptional one-of-a-kind luxury home. Contemporary, Tampa Flordia DSA

With its clean lines and crisp angles, this impressive five bedroom, three bathroom family home is a light-filled haven with generous, well-considered spaces. Polished concrete anchors the entrance and ground floor, with a floating timber tread staircase leading to carpeted living upstairs.
