Fast, Trustmark-Compliant fRsi Thermal Bridge Calculations

Expert 2D THERM modeling and IP 1/06 reporting to keep your project moving.

Our Process

1. Submit Project Details

Provide a description, photos, or architectural drawings of your junction using our secure form. We specialize in bespoke details and IP 1/06 requirements.

2. £120 Initial Modeling

We perform the complex 2D THERM mathematical modeling to determine your exact fRsi value.

3. £30 Report or Remodel

If the model passes, your official compliance report is £30. If it fails, we offer discounted remodeling at £30 per iteration to help you achieve a pass.

Please Note: We are independent thermal assessors, not designers. While we may offer mathematical observations on failing models, the liability for the design and any subsequent alterations rests entirely with your designer or architect.
