Frequently Asked Questions (FAQs)

What factors should I consider when choosing a cross laminated timber (CLT) supplier or manufacturer?

Start by evaluating their production capacity, product certifications, quality standards, delivery timelines, and pricing. Also, assess their experience with projects similar to yours and check for references or testimonials to ensure reliability and expertise.

How can I verify the quality of CLT products from a supplier?

Ask for product certificates, such as EN or ANSI/APA standards compliance, and request information on their quality control processes. Visiting their factory or reviewing third-party test reports can also help confirm the quality and consistency of their CLT panels.

What questions should I ask potential suppliers during my search?

Inquire about lead times, customization options (sizes, finishes, treatments), shipping logistics, after-sales support, and minimum order quantities. It’s also wise to ask for case studies or examples of previous projects to gauge their capabilities.

How do I compare prices between different CLT manufacturers?

Request detailed quotations that include material costs, customization fees, shipping charges, and any additional services. Make sure you’re comparing like-for-like products and specifications, as quality and finishing levels can significantly affect price.

Are there benefits to choosing a local supplier versus an international manufacturer?

Local suppliers can often offer quicker deliveries, lower shipping costs, and easier communication. International manufacturers might provide more competitive pricing or specialized products, but consider potential delays, import duties, or regulations before making a decision.
