Your Timber Frame Options

Building Regulations are a seemingly ever changing set of requirements laid down by Parliament to ensure that your new build house is built to approved standards. The Approved Documents that offer guidance on how to comply with the Regulations are listed below.

U Values

If you’re looking for a science lesson then take a look at the Wikipedia entry

We’ll attempt to give you a much simpler oversight here

U-values are a measure of thermal transmittance and express the rate of heat transfer through any element of your building, such as the wall, roof, window or indeed any structural component. The higher the figure, the worse the thermal insulation quality. So aim to keep your U-values low.

Because the construction of these elements can vary so much depending on your design and choice of materials, the U-values vary too and hence they need to be calculated specifically for each element. The units used to express U-values are watts per m² Kelvin (W/m²K). This means that if a wall, for example, had a U-value of 1.0 W/m²K, for every degree of temperature difference between the air on the surface inside the wall and the air on the surface outside, 1 watt of heat would pass through any m².

In addition to the Building Regulations, you may be asked to comply with other guidelines including CFSH (Code for Sustainable Homes), SAP (Standard Assessment Procedures), SBEM calculations (Simplified Building Energy Model) and EPC (Energy Performance Certificates).

When designing our Timber Frames, we have ensured minimal additional labour is required on site. Many of our competitors have taken the route of additional cavities to increase efficiency, but these systems take away valuable floor space and are costly to install in terms of time and money.

Whatever the requirements, Solo Timber Frame can guide you through what is one of the most confusing aspects of your Self Build.
