U-value Calculations & Analysis

What is U-value?

 

A U-value is a sum of the thermal resistances of the layers that make up an entire building element – for example, a roof, wall or floor. It also includes adjustments for any fixings or air gaps.

A U-value value shows, in units of W/m²·K, the ability of an element to transmit heat from a warm space to a cold space in a building, and vice versa. The lower the U-value, the better insulated the building element.

A building element’s U-value is extremely important as there are certain standards that should be reached according to Building Regulations / Standards.


 

How to find U-value?

To find your U-value, complete your U-value request by providing as many details as possible about your project via the U-value request form below.  U-value calculations can be performed free-of-charge to show compliance with current Building Regulations / Standards and best practice. They can be supported with a detailed report.

U-value calculations must be performed in accordance with BS 6946: 2007 using a method known as the ‘Combined Method’. Calculations should also be carried out in strict accordance with the guidance issued in BR 443 Conventions for U-value Calculations (2006). http://www.nsai.ie/

Condensation Risk Analysis

Condensation can substantially reduce the performance of insulation and could affect a building’s integrity. In order to predict any potential condensation before installing insulation, a Condensation Risk Analysis can be performed. Determining the risk of ‘interstitial’ or ‘surface’ condensation in a building depends on the components of the assembly, the order in which they appear in the construction, the building’s use and its geographical location (the calculation is based on specific local Met Office Data).

Condensation Risk Analysis for individual elements, performed in accordance with BS 5250: 2006 and BS EN ISO 13788: 2002, are supplied free-of-charge alongside U-value calculations produced by Kingspan Insulation’s Technical Services Department.
