Steel has a very high conductivity when compared with other construction materials In structures where steel elements are connected to other steel components, or where they penetrate the insulated envelope, careful design consideration is required if thermal bridging is to be avoided.

The building envelope makes a significant contribution to overall energy usage – therefore, tighter U-values in walls, floors and roofs is absolutely key. It’s why getting the design right from the outset is far less costly than retrofitting later. Here, Ben Cheetham, Specification Manager at Keystone Lintels, looks at the benefits of a one-piece thermally-efficient lintel including low thermal conductivity performance, buildability, improved SAP calculations and why they are up to five times more thermally efficient than standard lintels.

Seaton Beach Apartments in Devon is the first UK multi-residential development to be certified as ‘Passive House Plus’. Some claim that the Passive House standard is easier to achieve with simpler, box-like forms, resulting in finished buildings being aesthetically limited – but this is certainly not the case here. A little design ingenuity and the use of Schöck Isokorb thermal breaks has enabled generous sea-facing balconies with sweeping curves to create a striking finish.

Ravago Building Solutions, Europe’s largest manufacturer of XPS insulation, launched Ravatherm XPS X 200 SB earlier this year.

By offering some of the lowest U-values available, the patented PURe® aluminium window system from Senior Architectural Systems has become a firm favourite in the residential sector.

Cellecta, the UK specialist Acoustic and Thermal Insulation manufacturer have launched their Mojave® dry laid underfloor heating system. The system brings together a series of well-known components consisting of high-performance acoustic layers, XFLO® high-compressive strength extruded polystyrene (XPS), ULTRAplate aluminium diffuser plates or foiled faced (XPS), topped off with award winning overlay board ScreedBoard® 20.

Schöck explores a rare case where permission has been granted to demolish a Grade I listed Nash terrace and convert it back to the residential use for which the early 19th century building was intended. One of the key considerations with the new development was to prevent thermal bridging along the parapets.

John Rennie from NBT discusses the use of wood fibre insulation from the Pavatex range to enable thermal performance improvements to Aberdeen Art Gallery.

Illias Igoumenidis from Ecological Building Systems discusses the transformation of a derelict cottage into a desirable holiday retreat.
