Here’s a detailed examination of why Soudal HB Construct is the preferred adhesive for for Timber windows, doors and Kitchens and why B J Waller Ltd are proud of their partnership with Soudal UK and its fantastic HB Construct product:

Superior Bond Strength and Durability

Strength and durability

PU and PVA Glues:

PU glue is known for its strong bonding capabilities and moisture resistance, which is beneficial in woodworking. However, PVA glue, while easy to use and readily available, generally offers lower bond strength and is less resistant to moisture and temperature changes.

Soudal HB Construct:

Soudal HB Construct provides an exceptional bond strength that surpasses both PU and PVA glues, ensuring that timber windows, doors, and kitchen components remain securely fastened over time. This high-strength adhesive can withstand the stresses and strains encountered in these applications, contributing to the overall longevity and robustness of the products. The durability of Soudal HB Construct ensures that the joints and bonds maintain their integrity, even under heavy usage and exposure to varying environmental conditions.

Versatility and Compatibility

PU and PVA Glues:

PU glues are effective on porous materials like wood but may not perform well on non-porous surfaces. PVA glues are primarily suited for wood and paper, limiting their use in applications involving mixed materials.

Soudal HB Construct:

Soudal HB Construct is highly versatile and compatible with a wide range of materials. It can bond not only timber but also metal, plastic, and ceramics, which is advantageous in the construction of kitchens where different materials are often used together. This versatility simplifies the manufacturing process, as a single adhesive can be used across various components, ensuring consistent quality and performance.

Ease of Application and Cleanup

 

PU and PVA Glues:

PU glue can be challenging to apply and clean due to its expanding nature during curing. PVA glue is easier to handle but often requires longer clamping times and can take longer to set.

Soudal HB Construct:

Soudal HB Construct is designed for ease of application, with minimal mess and no expansion during curing. This feature not only reduces cleanup time but also ensures precise application and minimizes waste. Additionally, Soudal HB Construct sets faster than many PU and PVA glues, allowing for quicker manufacturing turnaround times without compromising the strength of the bond.

Environmental and Health Considerations

PU and PVA Glues:

PU glues contain isocyanates, which can pose health risks during application, necessitating protective measures. PVA glues, while safer, can still emit volatile organic compounds (VOCs), especially in large quantities.

Soudal HB Construct:

Soudal HB Construct is formulated with user safety and environmental considerations in mind. It offers a low-VOC formulation, minimizing health risks associated with adhesive use and promoting a safer working environment. This makes it a more environmentally friendly and health-conscious choice for the manufacturing of timber windows, doors, and kitchen components.

Conclusion

In the manufacturing of timber windows, doors, and kitchens, Soudal HB Construct emerges as a superior adhesive compared to traditional PU and PVA glues. Its outstanding bond strength, moisture and weather resistance, versatility, ease of application, and environmental safety make it the ideal choice for these demanding applications. By choosing Soudal HB Construct, manufacturers can ensure the production of high-quality, durable, and reliable timber products that meet the highest standards of craftsmanship and performance.
