Fiberglass is one of the most energy efficient construction material ready to be used for a new generation of windows.
Top Glass manufactures profiles according to specific customer drawings, helping designers and engineers to make the most of the potential of its TRIGLASS® profiles.
Typically, our TRIGLASS® profiles are used for designing:


Top Glass produces profiles that are used for windows frame designing mostly because they are extremely strong and light. The window systems made with TRIGLASS® profiles do not need any additional internal reinforcement with metal.
Reducing the bulk and weight of windows, they cut also transportation costs.
TRIGLASS® profiles, with their excellent thermal properties, allow also a slim and high-insulating frame structure. Fibreglass materials have a thermal conductivity coefficient around 0.3 W/mK that is incredibly low compared to aluminum and steel. They also guarantee high dimensional stability. They are stable like steel and stand up excellently in large temperature fluctuations. Minimal expansion and zero warping guaranteed.


Thresholds made with TRIGLASS® profiles for lift and alide doors and windows have better technical characteristics, in terms of heat transmittance, air permeability, water tightness andimpact resistance. They have a high load bearing capacity and thanks to their mechanical resistance they are suitable for heavy and large sliding windows. TRIGLASS® thresholds are light and easy to handle, transport and install. By using TRIGLASS® profiles you will save time on projects and simplify installations in case you are working in remote locations.
TRIGLASS® fiberglass profiles give also SHUTTERS a low weight and exceptional mechanical resistance combined with a high tolerance to sunlight. Unlike wooden and aluminum shutters, they do not need maintenance and they can last for years. Furthermore, thanks to the excellent insulating properties they protect from sun and high temperatures the internal of the house.



Accessory services that make our products more competitive

Our Technical Office is staffed with a qualified team skilled in the use of specialist machine tools. They are dedicated to studying required profilesoptimising forms and performing important operations such as cuttingdrilling and CNC machining. Top Glass can also provide customers with pre-assembly of the profiles as well as a coating service to satisfy particular aesthetic requirements.
Profile design

The Top Glass Technical Office works in close synergy with other departments to offer customers a timely and professional design service. We are offering optimal support on every decisions related to the profile design. Dimensionsthicknessform complexity, appropriate raw materials and mechanical specifications are the key aspects.

Internal laboratory

The Top Glass internal laboratory is equipped to perform mechanicalfire-resistance and dielectric tests on finish profiles in addition to the acceptance testing of incoming raw materials. We thus ensure compliance to the highest standards in product quality and traceability.
These tests are important because they ensure compliance with product technical requirements and international standards.

Post processing
Thanks to the versatility of its equipment, Top Glass offers a full customization service thanks to various post processing operations that provide added value and facilitate the use of TRIGLASS® fibreglass profiles when delivered to their destination. Every day, a highly trained technical team executes the daily operations phases consisting of cutting to sizedrillingmilling, bonding and pre-assembly, employing dedicated machinery which includes computer numerical control drills (CNC), shearers of various sizes, drilling stations and specially designed custom tools.
Warehouse services
Top Glass holds a warehouse with TRIGLASS® fiberglass profiles for prompt delivery. 
We store standard section products in various lengthsdimensions and colours.
Preparation times are typically 2/3 working days depending on material availability.
The warehouse service is suitable for those who need limited quantities of fiberglass products. Besides that it gives also customers the possibility to test the product before requesting high-volume production runs.
Surface coating

Given the market’s demand for increasingly high aesthetic performance, Top Glass can provide customers with a coating service for TRIGLASS® fibreglass profiles, suitable for both indoor and outdoor applications. The surface finish is obtained thanks to the use of fully automated machinery or, alternatively, inside cabins specially equipped to perform manual spray painting. Top Glass collaborates with qualified suppliers of coating materials. With their support, we optimise the selection of the appropriate type of coating to be used ensuring the required levels of adhesion together with excellent duration of aesthetic appearance over time.
