New Wimbish Housing
UK’s first rural affordable housing Passivhaus scheme
FLOORMATE 300-A – a STYROFOAM-A insulation material manufactured by Dow Building Solutions – is being used to insulate what is set to be the UK’s first rural affordable housing scheme to gain Passivhaus certification.
Produced at Dow’s facility at King’s Lynn, FLOORMATE 300-A is being installed below the concrete floor slabs of the ground-breaking 14 dwelling development in Wimbish, Essex, aiming for completion in Spring 2011.

The Hastoe Housing Association development aims to provide affordable homes for a rural community – whilst at the same time aiming for high levels of sustainability. The houses, a mixture of homes for rent and for shared ownership, are designed to be super energy efficient, and will not only comply with Passivhaus principles but also meet the demands of Level 4 of the Code for Sustainable Homes.
Passivhaus standard buildings retain heat from passive solar gain, eliminating the need for central heating and reducing fuel costs. The standard requires very high levels of insulation, a design that makes the most of solar energy and superb sealing throughout.
“As well as air tightness we’re aiming for U-values below 0.1 W/m2K for the walls, roof and floor in order to meet Passivhaus standards – which meant specifying effective insulation throughout,” explained Chris Parsons of Parsons & Whittley architects, the Norfolk-based designers of the scheme.
“Installing insulation below the slab helps create an ‘envelope’ of continuous insulation which minimises heat loss, requiring a material which can maintain strength and good thermal performance, even when used externally.”
FLOORMATE 300-A is highly durable with excellent moisture-resistance and compressive strength, enabling the insulation to perform outside the waterproofing envelope.
“We’re seeing increased interest from forward-thinking architects and developers in building methods such as Passivhaus, but it requires a completely new way of thinking when it comes to maximizing the thermal performance of the building fabric,” said Matthew Dyke, Account Manager for Dow Building Solutions.
“Installing insulation below the slab helps to avoid thermal bridges at floor and wall junctions and makes the most of precious internal space, which is why it’s becoming recognised as a more effective way of insulating new buildings.”
Parsons & Whittley’s design for the development, which is being built by Bramall Construction and assessed against Passivhaus standards by specialist consultancy Inbuilt, is based on FLOORMATE 300-A insulation running below the entire floor slab, solid aircrete external walls wrapped in over 250mm of foam insulation, and conventional insulated ceilings.
To find out more about the Wimbish Passivhaus development visit the microsite at www.wimbishpassivhaus.com where you can follow the build on a blog and view a picture gallery of construction as it progresses.
FLOORMATE 300-A is available in a range of thicknesses: 50mm, 75mm, 100mm, 125mm and 150mm, and has a design load of 130 kN/m2. The material is manufactured using technology that takes CO2 from industry and uses it as a blowing agent in order to create insulation foam with a Global Warming Potential (GWP) of less than five.
