House Kit Specifications

The Price Guide shown are inclusive of all items as detailed in our house kit specification.

Our sales team will be happy to advise you on the various options which are available, allowing you to personalise the final specification of your new Scotframe home.

We will then be pleased to provide you with a detailed quotation, inclusive of your chosen amendments and delivery to site.

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.

Open panel systems

Traditional timber frame uses an open panel system for the external walls. The panels are typically made from a softwood timber frame and sheathed in the factory with structural sheet material, such as plywood or oriented strand board (OSB).

A reflective water-tight, yet breathable, membrane is factory fitted on the outside panel face and left open on the inside (hence the name). The insulation which is fitted within the panels is installed on-site once the panels have been erected and the services roughed in following which the plasterboard is site fitted.

Closed panel systems

Val-U-Therm, our closed panel system has both sides of the external wall panels sheathed in the factory with structural sheet material such as plywood or oriented strand board (OSB). The internal void left is then high pressure injected in the factory with a high performance PU insulation. A reflective water-tight, yet breathable, membrane is factory fitted on the outside panel face. A reflective vapour control layer and service zone battens are factory fitted on the inside face which ensures a very good level of air tightness. Once the services are roughed in within the service zone provided, the plasterboard is site fitted. We also offer the option for doors and windows to be factory fitted.
