A project briefing
After spending the last 5years living in an eco friendly energy efficient StyroStone property in Spain we moved back into our old property in the UK.
This house was built in a traditional manner out of block work and stone by myself to a high standard, however it was constructed in line with current building reg. Standards (for 1998). After the first month we were alarmed that we had ran out of fuel for our heating for the second time.
At first we thought that there had been a leak in the service pipe or that we had been subject to an act of fuel theft. Only after closely monitoring our fuel use did we realise it was due to the fact that fuel cost had risen so dramatically, that what we had spent, that had previously been sufficient to see us through the winter was now only lasting a few weeks. We decided to commence on a programme of retrofitting internal insulation and other measures to reduce our bills.
At the same time my son had purchased a terraced property in the same town which was in need of total renovation. We decided to apply all of the principles of a StyroStone construction to the renovation of this property as well, and thus take the property from a "G" rating to a respectable "B" rating, hence reducing Carbon emissions and energy bills by up to 80%.
Our train of thought was to do as much as possible on a £20,000 budget so that this could be tagged onto the mortgage for a minimum monthly repayment, compared to doing minor upgrades and having to suffer ever increasing energy bills whilst living in this property. This way my son would know what his fixed expenses were and would always have more disposable income on a week in week out basis.
THE EXISTING PROPERTY
42 Pill Street, Cogan, Penarth was built approx 110yrs ago of solid wall construction. It had since been upgraded by having the front elevation rebuilt in cavity work with 25mm foam insulation. This also applied to the rear annex. The property had originally been a 3 bed, 2 reception no bathroom house however the rear bedroom had been converted to a bathroom.
Gas fires were installed in a poorly constructed rear ground floor kitchen extension, with flat roof, and in the lounge.
The front room floor had been renewed in concrete and screed however the middle room still boasted a suspended timber floor. The wiring was in poor condition. The roof space on the extension and the main building were uninsulated.
The plan was to reduce the size of the bathroom on the first floor and introduce a shower alongside the bath. Make room for a boiler and thermal store and to convert the loft space for use as an additional store space/office area.
Although building regs/planning were not required or applied for, we were to construct everything in accordance with and where ever feasible supersede building reg requirements. This way, should any future occupier wish to use the roof space as a third bedroom, permission could be applied for and approved without problem.
As previously stated our main drivers for retrofitting the property were to reduce fuel bills and carbon emissions by up to 80% and enable my son to live in comfort without paying on an escalating curve.
The priorities were to make the property air tight, super insulate the walls and roof and fit suitable heating systems for space and hot water. This would be via a gas condensing boiler and solar panel. If the budget permitted, we would fit MHRV, however it may, at this stage, be only affordable to pre fit the ducting for this system and add the main unit at a later date.
It was necessary to rewire the property and fit new kitchen and bathroom. The kitchen would be eco friendly and contain "A" rated appliances.
We would also insulate the floors where possible.
Research proved that Kingspan K17 phenolic foam backed plaster board were the best option to line the external walls of the property to give the best U value. These boards are a total of 92.5mm thick however due to the size of the rooms, once fitted the loss in space is not noticeable.
Celotex 75mm was used between the roof rafters in conjunction with Web Dynamics TLX silver multifoil for the insulation of the loft space. This would assist in our goal of air tightness. One of the natural by products of building with StyroStone permanent Insulated Formwork, is that being a mono coque structure, it is inevitably air tight.
The work force on this retrofit project were given tool box talks on the how's and why's of making a building air tight. Explanations on how this can be checked and monitored using infra red and thermal imaging, ensured that guidelines were adhered to. Once the team is on board and understand the dynamics, the rest is easy!
By far the simplest and most effective measures that can be taken to reduce fuel bills is to fit insulation to the fabric of the house and make it air tight. The house then performs just like a Thermos flask, it will maintain whatever temperature you have inside it as long as there is no leaks or escape paths for the energy to leave.
If the heat does not escape you do not need to keep burning fuel to replace it , and if you are not burning fuel you are reducing your carbon footprint and saving money at the same time. A true win win situation!.
If you were sat in a room and £5 note blew out of an open window, you would get up and chase it down the road, and yet this in reality, is what we ignore every day that we live in a draughty poorly insulated house! Money escaping through the walls and roof.
Why go to building regs which only suggest the minimum? Why wait for them to change?
Go for the best insulation now and start to save money.
In this economic climate it is a better investment than an ISA.

If you have desires of building in your dream destination, however want to use a team you can communicate with effectively, Contact us for more information at .
The team at Clean Footprint is made up of a nucleus of highly experienced construction contractors ranging from groundworks specialists to formwork ,civil engineering and specialist house builders.
The team have all worked together on various projects over a period spanning 20yrs.
All have the common goal of providing a superior standard of quality in their product and ensuring that the construction period is reduced to a minimum without compromise.
As ICF Contractors we aim to provide a service tailored to individual project requirements whilst respecting environmental issues.
Clean Footprint promotes the use of StyroStone insulating forms for its structural wall elements.
Having researched the market for 10yrs we find that although most ICF providers are of high quality, StyroStone have the edge with their broad spectrum of blocks providing the requisite u value to suit individual projects and their “complete system” eliminating the need for additional timber shuttering around windows , door openings etc.
