Scandinavian insulated raft foundations have now arrived in Ireland. Whether you are building to current building regulations or want to achieve low energy or passive house standard, with the help of Supergrund, we have an insulated foundation design for your building project.

Using only air as the insulating gas, the system can deliver U Values as low as 0.1W/m2K. Insulated Raft foundations are suitable for use with Timber or Block construction methods.

Building, literally on three unique properties of EPS; high compressive strength combined with extremely low water absorption and excellent insulating values, the load bearing walls and floor slab of your building sit on top of the insulating layer practically eliminating heat loss to the ground.

The most common insulated foundation system used in Ireland today is the Supergrund system. Enervate are trained installers of this system which is manufactured by Aerobord Ireland to the specifications given by Supergrund, the Swedish company who own the system. It provides precut forms for a reinforced concrete ringbeam around the perimeter of the building that are cut to suit each individual project, meaning they can then be assembled on site, like a jigsaw, to give a permanent formwork for the ringbeam that also insulated the foundation.

Under the floor slab is usually insulated with 200mm - 300mm of standard polystyrene to provide passive levels of insulation. Where there are load-bearing internal walls, carrying some of the building weight, the floor slab is thickened locally and the polystyrene underneath the wall is upgraded to a structural grade to carry these loads. The floor slab is generally reinforced with steel and reduced to 100mm thick, and extra reinforcement is used under the load-bearing internal walls. Enervate also use this system for extension projects.

Retrofitting | Enervate

This involves the fixing of insulation to the outside of your house, and then applying a basecoat render, with a layer of fibre mesh and finally a finish coat of render to the colour of your choice. This involves changing your existing oil or gas boiler with a condensing boiler, which uses the fuel much more efficiently, and improving the way in which it is controlled.


Air-tight Systems | Enervate

This ensures optimum protection for all fibrous insulating materials in all constructions, whether they are vapour diffusion permeable or vapour diffusion resistant externally such as pitched roofs with bitumen sheeting or metal sheet roofing, flat roofs and walls with a diffusion resistant exterior cladding.


Services | Enervate

Retrofitting refers to the addition of new technology or features to older systems, in this case older or existing buildings, to improve energy efficiencies. External Insulation, Attic / Roof Insulation, Wall insulation, Cavity Wall Insulation, Internal Dry-lining, Boiler and Heating Controls Upgrade. Have you ever seen a polar bear or a seal with its fur under its skin. Yet most homes and commercial buildings are insulated from the inside.


External Insulation | Enervate

Whether you are planning the construction of a new building or renovating an existing one, Enervate can offer you a durable, cost-effective solution in keeping with the highest standards of the construction industry. Outsulation (External Insulation and Render Systems – EIRS) is a type of building system that provides exterior walls with insulation, finished surface and waterproofing in an integrated composite system.


Extend & Renovate | Enervate

We will design the best solution to meet your requirements prior to construction, and using our tried and tested system suppliers ensure that the chosen system is fitted and guaranteed to the highest standards. Chimneys are among the biggest offenders when it comes to heat-loss and draughts, but we have a number of remedies for these also, without losing that ‘real fire’ cosiness that we love so much in this country.


Low Energy & Passive House Construction

By using more up to date building methods, and paying extreme attention to details, we can bring your house to any energy rating you like, right up to Passive-House standards. We can accurately calculate the space heating demand, and energy consumption of your new home, long before you start building. You will have the comfort of knowing that it is built well, and will be easy to keep warm.
