Ancon Thermal Windpost | A Smarter Specification for Masonry Construction

Unlike traditional windposts, the Thermal Windpost incorporates thermal insulation within the structural solution, helping to reduce heat transfer through the building envelope.

Key Benefits:

✅ Up to 70% reduction in thermal transmission 
✅ 35% lighter than a standard windpost
✅ Supports Passivhaus and low-energy buildings
✅ Faster installation and easier handling
✅ Expert design and specification support

CPDs & Product Training 

Join our upcoming webinar to discover how Thermal Windposts can help reduce thermal bridging in masonry wall constructions and support improved as-built thermal performance.

We'll explore the impact of windpost design on building efficiency, how Thermal Windposts can reduce thermal transmission by up to 70%, and the role of specification in helping to close the building performance gap.

Presented by Sara Dawes, Regional Technical Sales Manager at Leviat, this session will provide practical guidance for architects and specifiers, with the opportunity to ask questions and gain expert insights.

FAQ's

Is the Thermal Windpost more expensive than a standard windpost?
While initial costs may be slightly higher, the product delivers added value through enhanced thermal performance, reduced energy loss and support for low-energy building targets.

How does it reduce thermal bridging?
Its insulated design significantly reduces heat transfer compared to conventional steel windposts.

Can it support Passivhaus projects?
Yes. The Thermal Windpost has been developed to support low-energy building strategies and thermal-bridge reduction.

Does it help with Part L compliance?
Yes. Improved thermal performance can support energy-efficiency objectives and compliance requirements.

Is performance data available?
Yes. Thermal modelling reports, calculations and technical evidence are available.

Will it contribute to BREEAM targets?
Yes. It can support sustainability assessments through improved thermal performance and EPD documentation.

Are BIM objects available?
Yes. BIM, Revit files, CAD details and NBS resources are available.

What technical support is available?
Leviat provides design support, technical guidance, specification assistance, CPDs and site support.

Can Leviat help with project-specific design?
Yes. Technical teams can provide project-specific recommendations and design assistance.

Is the product manufactured in the UK?
Yes. Thermal Windposts are manufactured in Sheffield.

How quickly can I specify it?
Immediately through the configuration tool, NBS resources and direct technical support.

New EPDs for Key Product Ranges

Environmental Product Declarations (EPDs) covering two key masonry support and restraint solutions from our trusted Ancon product range are now available. Architects, engineers and contractors can now access these verified documents which provide clear, comparable data on the full lifecycle impact of our products.

Thermal efficiency in buildings - can we afford to turn a blind eye?

Senior Engineer, Jeff Edwards explores an issue that has become common knowledge in the construction industry, that designed thermal performance figures for cavity wall constructions are rarely achieved under actual site conditions. He lets us in on how his passion for addressing this 'performance gap' resulted in the creation of the revolutionary Ancon Thermal Windpost (TWP2).
