Each element of the building envelope - wall, roof and floor has a role to play in minimising heat loss. The insulating effect of each of these elements is measured by its u value - the lower the U-value, the better its thermal performance.

Because Val-U-Therm® provides such a high level of insulation it reduces the need to install costly renewable energy systems. What’s more, an investment in Val-U-Therm® wall, floor and roof panels will last for the life of the building - unlike renewables that need to be controlled, require frequent maintenance and, often, wholesale replacement during the lifetime of a property. In contrast, the Val-U-Therm® system is a Fit and Forget, Fabric First solution.

Building towards greater energy conservation

All new buildings must now reach increasingly higher standards of energy conservation. The Code for Sustainable Homes, Approved Documents Part L of the English Building Regulations and the Scottish Building Standards are all driving the reduction of carbon emissions in new buildings. Building in timber frame makes it easy to achieve a high performance building fabric that maximises thermal performance and minimises unwanted air leakage.

Scottish Building Regulations - Section 6

For nearly fifty years, Scotland has had its own set of Building Regulations. For many years the energy standards in the regulations were set at a modest level, broadly following those that existed in the remainder of the UK. As we moved into the 21st century and the climate change agenda gathered momentum, the energy standards incorporated the best levels of thermal insulation in the UK, reflecting Scotland’s colder climate.

The standards introduced at the start of October 2010 reduce the CO² emissions from new buildings by a further 30% from the 2007 Regulations. These standards are comparable with the best in Europe. All things being equal, the new Scottish Building Regulations will reduce CO² emissions from new buildings by around 70% when compared to the 1990 standards.

English Building Regulations - Part L

Part L of the Building Regulations requires that throughout the building process, greater attention be paid to every factor that contributes to the energy consumption or heat loss of a building. As this Regulation now requires a ‘whole house’ approach to demonstrating compliance, developers are required to meet an overall energy performance target. There is also a greater emphasis on ensuring that the building construction meets the standards assumed at the design stage and that the heating and hot water systems are correctly commissioned.

As the energy efficiency standards in Approved Document Part L are further strengthened in the 2010 amendments, requiring a 25% decrease in target CO² emissions and lower levels of unwanted air-leakage, the high performance building fabric of timber frame makes the new targets easily achievable.

Code for Sustainable Homes

The UK government has set the building industry a series of progressively more demanding targets that aim to substantially reduce CO² emissions from all new build homes, with the ultimate goal of a zero net carbon standard by 2016.

Achieving the necessary compliance credits for The Code for Sustainable Homes (CSH) requires a greater emphasis not only on energy-saving technology, but also on using building materials with less embodied carbon.

The choice of building fabric has a major effect on a home’s overall energy consumption, as well as its environmental rating. In both of these considerations, timber frame scores highly and is fast being regarde

Each element of the building envelope - wall, roof and floor has a role to play in minimising heat loss. The insulating effect of each of these elements is measured by its u value - the lower the U-value, the better its thermal performance.

d as the natural solution for Code compliance. The cost of meeting minimum heat loss parameters is lower, compared with other build methods. Timber frame also helps to deliver the air-tightness and acoustic performance required to meet the demands of their respective Code categories.

Thermal performance

Timber frame has advantages over masonry construction because it allows a greater thickness of insulation to be fitted within the external walls. To achieve equivalent U-values in masonry would require an increase in the overall wall thickness resulting in increased underbuilding and foundation costs.

Timber frame allows lower U-values (the lower the U-value the higher the standard of thermal performance) to be achieved within standard constructions.

The kit specification shown is based on the area-weighted average 'U' values (W/m2K), permitted under the Scottish Building Standards Section 6 - Energy for the floor, walls & roof. The windows, rooflights & external doors have 'U' values considerably better than the area-weighted average permitted.
