Get to Know GRANTS and Its Structural Strength from Within

When talking about TOSTEM’s flagship product, GRANTS, most people know it for its unparalleled strength and durability. It comes as no surprise, as GRANTS remains the top choice for high-rise buildings in battling the elements high up in the sky. Its functionality even extends to buildings by the sea in many cases. And for owners of regular houses that use GRANTS in their design, it simply means they have a product that will last them several years.


That’s why we’d love to tell you a little bit more about the aluminium door and window frame collection known as GRANTS. Read on to find out how it has been designed for durability while not sacrificing on aesthetic value, and why contractors and architects trust the brand to play an active role in the construction of several residential areas in Thailand.

Overlapping Meeting Stile

Designed for maximum durability without sacrificing beauty in design, the sliding doors were crafted to overlap in a contemporary style like no other. No aspect seems out of place when the doors are open and become one with the other; Not to mention you’ll get the peace-of-mind of having an extremely durable door that has been designed through innovation from the ground-up.

Double Barrier Drainage System


Every single part of the frame was designed for efficiency in operation, and this especially applies to GRANTS’ lower profile. Its double barrier drainage system is hidden from plain sight in the bottom part of the frame, albeit on purpose, for enhanced aesthetic value. The design was also crafted to improve water draining capabilities, while maintaining the same sleek, modern look and feel.

Outstanding functions


GRANTS series products are built to withstand the surrounding environment, providing long lasting durability, with features that meet global standards i.e. windproof performance, watertight performance, airtight performance and soundproof performance up to 25 decibels.

Besides, GRANTS’ innovative ventilation system (Extra Feature) is designed to be hidden inside the window frame, bringing in fresh air from outside through the central ventilation slot.
