Vexpert, your specification expert, helps architects, engineers, interior designers and contractors specify exactly the right products for their project, without the sales pitch, the emails and the incessant phone calls.
It is a tool for professional problem solvers: data-driven people who need to research and understand, and then build with confidence and avoid failure.
How It Works
Tell us about your project and where it is.
Choose the area of the building and where the product sits.
Enter details about the product type, for example for expansion joints enter the gap width, finish depth, movement and loading.
Review the top five recommended products, with data sheets.
Not sure which product? Search by project to see the products ranked for your building. Already know it? Use Search by product name or code to go straight to it.
Search by project
Type your building or area – for example products suitable for a hospital, stadium concourse or car park top deck – and see the products ranked for it, best first.
Search by product name or code
Type its name or code – for example TransAtec 1105, 376-C07-050 or MicrAtec NL – and pick a match. You choose the size and options on the product page.
Document downloader Vexcolt staff

or find the right product for your project
Start with your project details below, then select Submit to choose your product.
The five products shown are the highest-ranked suitable series for this application and joint position, in the order set by the ranking file. For each, the size is chosen by the Vexpert logic flow: your gap width or the next size up, then a recessed joint at your finish depth or shallower (both are shown when both exist), or a surface-mounted joint at any depth. Only the location code named in the ranking column (A01, A02, A07 or A09) is matched, so B, S and V variants are not offered.

Who we are
Vexpert is Vexcolt's specification tool. Vexcolt (UK) Limited is the data controller for the personal information you give it.
What we collect
Your sign-in email, and the time you sign in. We send a one-time code or link to it; there is no password.
Your access request: name, company, email, phone number, role and country, and whether your request was approved.
What you do in Vexpert: the projects you enter, the answers you give, the products recommended, the files you click to download, the project schedules you build (including any notes you add) the products you save as favourites and which notifications you have read. This is what lets you come back to your projects.
How you use Vexpert: how long Vexpert is on screen during each visit, how far you get through each search (for example the last question you answered), which recommended products you open and how long that takes, the sizes, finishes and other options you choose on product pages, and how often you come back to a project.
Questions you ask "Ask Vexpert": the question, the product it was about, the answer given and whether it referred you to our technical team. On vexcolt.com the ready-made answers come from Vexpert's own product data, and a question you choose to send to our technical team is kept with your account, answered by a member of the team and emailed to you. Where Ask Vexpert is answered by Claude (an AI service from Anthropic, in the claude.ai version), it uses only Vexpert's data for that product, through your own Claude account; we do not send it your name or contact details.
Document requests: when you press Request for a document, on a product page or in a Vexpert PDF, we keep your name, email, company (if given), the document, its reference and the project, so our technical team can email it to you. Requests are also passed to our customer records system.
Emails you ask for: when you choose "Email me this PDF" we send the PDF to the email address of your Vexpert account and keep a record that it was sent (not the PDF in that record).
Recommendations prepared for you by Vexcolt staff: the name, company and email address the staff member enters for you, which are printed on the PDF. If they choose "Send to customer", we email the PDF to you with a copy to them, and keep a record that it was sent.
Recommendation documents: each PDF made in Vexpert is stored online so that the QR code printed on it opens the document. The link is long and random, but anyone who has the QR code or link can open that PDF.
Quote and sample requests: your contact details, the delivery address and postcode, the products, quantities and any notes you send.
Vexpert sets no advertising or analytics cookies. Your browser keeps your sign-in session and your current answers so the page works; that is all.
Why we use it
To run Vexpert for you and answer your quote and sample requests (steps you have asked us to take).
To approve who can use a professional specification tool, keep it secure and spot misuse (our legitimate interests).
To see which products people search for and cannot find, where searches stop, which products are opened and which options are chosen, so we can improve Vexpert and the range (our legitimate interests). We look at this mainly as totals.
To understand which companies and projects use Vexpert, which projects people return to and which quote requests lead to orders, so our technical sales team can support those projects (our legitimate interests). Quote outcomes are taken from our own CRM records.
To tell you, when you sign in, about changes to products you have used (for example a renamed product or corrected codes).
To contact you about your projects and requests. We will not add you to marketing lists unless you ask.
Who sees it
Vexcolt's technical sales and admin staff. The data is stored for us by Supabase (database, sign-in and stored documents, hosted in the EU) and sign-in codes, alerts and the PDFs you ask us to email are sent by Brevo (email, EU). Ask Vexpert questions are answered by Anthropic's Claude service under your own Claude account. They act only on our instructions or yours. We do not sell or share your details with anyone else.
How long we keep it
Your account, projects and searches: while you use Vexpert and for 3 years after your last sign-in.
Quote and sample requests: 6 years, as a business record.
How you use Vexpert (visit times, search journeys, options chosen, Ask Vexpert questions): with your account, for up to 2 years, then only as totals without names.
Stored recommendation documents (PDFs): up to 2 years.
Search totals used to improve the range are kept without names.
Your rights
You can ask to see, correct or delete your information, to limit how we use it, or to receive a copy, by emailing info@vexcolt.com. You can also download your own projects at any time from My projects. You can object to the use of your activity for improving Vexpert or for sales follow-up at any time by emailing us; we will stop. If you are unhappy with how we handle your data you can complain to the Information Commissioner's Office (ico.org.uk).
