Recommendation Letter on Perlite Plaster by Weltez Building Chemicals Inc.
Prof. Dr. Salih Taner YILDIRIM

 

As an academician and consultant focusing on perlite-based building materials since 2008, I have contributed to the development of many innovative products in this field. Through supervising graduate theses, scientific articles, and projects, I have extensively examined the potential of perlite in the construction industry. During this process, I worked with various manufacturers, exploring different formulations and application techniques. However, the perlite plaster product developed by Weltez Building Chemicals Inc., which I have consulted for, stands out as one of the most successful and impressive products I have encountered so far.

 

This perlite plaster is particularly notable for its adhesion capability, homogeneous distribution, and the high compressive strength achieved after hardening. It adheres perfectly to surfaces during application and shows no issues such as cracking or detachment over time. This feature provides a significant advantage for both applicators and end users.

 

The most striking aspect of this product is its thermal insulation performance. Laboratory tests reveal a low thermal conductivity value of 0.045 W/m·K, clearly demonstrating that this material can compete with commonly used insulation materials like rock wool, EPS, and XPS. Moreover, this success is not limited to numerical data but also proven in real-world applications.

 

Another important advantage of Weltez perlite plaster is that it eliminates the need for doweling. Dowels used in traditional insulation systems create costs in terms of labor and time and can cause structural weaknesses on reinforced concrete surfaces. This plaster, thanks to its direct application to the surface, removes such issues, speeding up the application process and making it safer.

 

Additionally, the fire risk associated with widely used insulation materials on the market is a serious concern. Materials such as EPS and XPS easily catch fire at high temperatures, causing rapid fire spread between floors and releasing toxic gases that threaten safety, especially in enclosed spaces. Weltez perlite plaster, with its Class A non-combustibility, eliminates this risk and maintains safety even during fires withstanding temperatures up to 1000°C. Furthermore, it produces very little smoke even at very high temperatures during combustion, a crucial feature that distinguishes it from similar products.

 

In terms of water absorption, this product is also highly successful. Its special polymeric additives minimize water permeability, extending the material’s lifespan and preventing moisture-related deterioration. Thus, it offers a durable and long-lasting solution even under humid climate conditions.

 

In conclusion, this perlite plaster developed by Weltez Building Chemicals Inc. goes far beyond existing products in the sector in terms of both technical features and ease of application. The widespread adoption of this product will pave the way for safer, more economical, and environmentally friendly solutions in the construction industry. As an academician and consultant, I wholeheartedly recommend this product and encourage all professionals in the construction sector to consider this innovative solution.
