About Us
Welcome to Reviny.com, a free online platform designed to make U-value calculations, thermal insulation, and building energy efficiency easier to understand.
Our goal is to provide simple, practical, and accessible tools that help homeowners, builders, renovators, students, and anyone interested in building performance better understand heat transfer and insulation.
What is Reviny.com?
The U-value, also known as the thermal transmittance value, is an important measurement used to evaluate the thermal performance of building components. It indicates how much heat passes through a building element under a given temperature difference.
At U-WertRechner.com, users can explore and calculate U-values for different types of building components, including:
- External walls and facades
- Roofs and roof insulation
- Floors and floor structures
- Windows and glazing
- Different insulation and construction materials
Our online calculators allow users to consider factors such as material thickness and thermal conductivity to estimate the thermal performance of a building component.
Our Mission
Our mission is simple: to make energy efficiency easier to understand and more accessible.
Proper insulation can help reduce heat loss and may contribute to lower energy consumption. We want to provide useful online tools and clear information that help users understand insulation options and compare different building constructions.
We believe that better decisions start with better information.
Simple and Practical Online Calculators
We focus on creating easy-to-use online calculators that can be accessed directly through a web browser without requiring additional software.
Our tools are designed to help users understand important concepts such as:
- Thermal conductivity (λ)
- Material thickness
- Thermal resistance (R-value)
- Overall thermal resistance
- U-value in W/(m²K)
Who Is Our Website For?
U-WertRechner.com is designed for a wide range of users.
Homeowners can use our tools to get a better understanding of the thermal performance of their homes.
Builders and renovators can compare different materials and insulation thicknesses during the planning process.
Architects, planners, and construction professionals may use our calculators as a convenient reference for basic calculations.
Students and anyone interested in building science can also use our website to learn more about U-values, insulation, and heat transfer.
Our Commitment to Quality
We aim to present our information and calculation tools in a clear, useful, and responsible way. Our calculators are intended to provide practical estimates based on commonly used principles of building physics and thermal calculation.
However, the results provided by our online calculators should be considered for informational and preliminary planning purposes only. Complex construction projects, building regulations, moisture protection, thermal bridges, and professional energy assessments may require advice from a qualified architect, engineer, energy consultant, or building physicist.
Supporting Energy-Efficient Buildings
Energy-efficient construction and renovation are becoming increasingly important. A well-designed building envelope can help reduce heat loss and improve the overall energy performance of a building.
Through our calculators and educational content, we aim to help users understand how materials, insulation thickness, thermal conductivity, and U-values are connected.
Our long-term goal is to build a useful resource covering U-values, thermal insulation, building physics, energy efficiency, and energy-conscious construction.
Independent Information
U-WertRechner.com is an independent information and calculation platform. We are not tied to a specific insulation or construction-material manufacturer.
Our focus is on providing practical tools and understandable information so that users can explore different options and make better-informed decisions.
