We’re excited to share more details about the installation process of a Triotherm insulated door upstand for a sliding door, recently used in our own retrofit project. Since most sliding doors come with a frame depth exceeding 125mm, you may need to extend the standard Triotherm+ profile by incorporating a structural insulation board upright or even by using two rows of Triotherm+ for optimal results.

Proper positioning of Triotherm Door Upstands is crucial to ensure optimal thermal performance while minimizing disruptions to subsequent trades. Ideally, the upstand should align closely with the top of the door or window frame. The exact placement within the door or window opening will depend on the specific wall construction. In general, the door upstand should align seamlessly with the building's thermal envelope for optimal performance. Below, you'll find guidance tailored to the most common wall systems.

In response to frequent inquiries about the available dimensions of Triotherm Door Upstands, we want to provide a clear guidance on dimensions. Our goal is to help you better understand the requirements with ease and clarity.

We frequently receive questions about the proper waterproofing setup for Triotherm. To clarify, we’ve outlined the correct approach below.

Always available in 1,175mm length per profile but extendable to any required length through dove tail interlockings.
