Thermoblock is a load bearing thermal insulation block which eliminates the cold bridge at the wall/floor junction.

Marmox Thermoblock is a highly insulating, load-bearing building which is placed at the base of a perimeter wall to eliminate or significantly reduce the thermal bridge at the junction with the floor.  Our thermal bridging block is made of a  strong and rigid epoxy-concrete frame that is integrated with our own fire-resistant XPS that gives the outstanding thermal insulation providing psi values of between 0.03 to 0.07W/mK. 

Although Thermoblocks are lightweight they are extremely strong and stable having a mean compressive strength of 9.0N/mm2 so can be used in most walls.

 

Compliance to Building Regulations

All building regulations in the UK and Ireland now say: “The building fabric should be continuous over the whole building envelope and constructed so that there are no reasonably avoidable thermal bridges in the insulation layers caused by gaps in the various elements.” 

Marmox Thermoblock satisfies this requirement perfectly by connecting the wall insulation with the floor insulation.

 It can be demonstrated that incorporating Thermoblock into the design will reduce associated CO2 emissions significantly to allow the property to be categorized as at least Class 4 and with other measures will contribute to achieving CfSH levels 5 and 6. Thermoblock will also meet the requirements of the ‘new’ Target Fabric Energy Efficiency / Target Primary Energy Consumption.

 

 Is Thermoblock right for your Design?

The standard Thermoblock height is 65mm however to achieve an R Value of 2, we can also manufacture a 100mm thick version.  The block is available in three widths: 100mm, 140mm and 215mm  and are suitable to form the base of walls comprising brick, block or wooden frame. 

To insulate beneath parapets or if torch applied bituminous membranes are being applied, the flame resistant Marmox Thermoblock-PIR, “the Parapet Block” should be used.  These blocks are 53mm thick and available in 100mm and 140mm wide versions

ENERGY CONSULTANT SELECTS THERMOBLOCK FOR FOREVER FAMILY HOME

March 2019

When the founder of the Complete Energy Consultancy set about designing a brand new home for himself and his family, he identified Marmox Thermoblock as the ideal means of tackling thermal bridging around the floor/wall junction of the near-to-zero carbon construction solution.

The location of Richard Britten’s super-insulated four-bedroom property is only a few miles from the family’s current Gloucestershire property, but centuries away in age and technology. Not only will the Cotswold Stone clad walls offer a U-value of 0.1 W/m2K, but the dwelling’s hot water and negligible space heating needs will be met using a ground source heat pump.

In erecting the walls, locally based MH Bricklaying is consuming a total of 184, 100mm x 600mm Thermoblocks, laid at the base of the 100 mm thick dense concrete blockwork outer leaf. This is separated from a similar inner leaf by a 300mm wide blown-bead filled cavity.Also, due to being supported off a concrete beam-and-block floor construction, the internal block walls will require a further 34 of the 140mm wide units, all supplied by builders merchant, Buildit in Gloucester.

Richard Britten commented: “Basically we are moving from an old cottage with thick stone walls and window seats, which was hard to heat, to a very high performance property that despite the 150 mm quarried Cotswold Limestone face, will require minimal heat input. Although I hadn’t used Marmox Thermoblocks before, they are the ideal solution for tackling cold-bridging around the perimeter and where the internal block walls sit on the beam-and-block floors.

The design I arrived at with our architect – Church Architectural which is also based nearby – combines thermal mass with excellent insulation, the floor construction also being covered by 300 mm of polystyrene. It is proving to be a very interesting project which should offer a comfortable living environment with negligible running costs.”

As a loadbearing composite product, Thermoblock has been developed to be incorporated into various wall constructions as a horizontal layer, equivalent to a course of bricks, in order to address a critical area of heat loss, thereby reducing energy bills and making a significant contribution to SAP (Standard Assessment Procedure) calculations.

Each length of Thermoblock is comprised of ultra-high performance XPS insulation, encapsulating miniature columns of concrete, while the top and bottom are covered by alkali resistant glass-fibre mesh, retaining a surface of fibre reinforced polymer concrete to facilitate bonding.

The concrete columns have a very low conductivity so do not present thermal bridges themselves and when coupled with the highly insulating XPS insulation core, a combined thermal conductivity of 0.47W/mK is achieved.

Crucially, being able to employ a defined, very low thermal transmittance – derived by thermal modelling or measurement – offers a far more advantageous result than adopting the ‘default’ figure offered in SAP, which can often result in non-compliance under Part L.

Marmox Thermoblocks tackles thermal bridging around Harrogate home's basement

March 2018

Some 180 Marmox Thermoblocks have been supplied to a regional builder for the construction of a high specification home near Harrogate, with their unique combination of insulating and load-carrying properties being used to tackle cold bridging where the two storeys above ground meet the basement structure which contains a swimming pool and other recreation areas.

The five bedroom property has been built by Dobson Construction with a beam and block ground floor being supported off the in-situ concrete basement walls. The partially filled external wall of dense concrete blockwork, with an outer leaf of quarried stone, was then raised on the continuous course of Thermoblocks.

The 65mm x 215mm x 600mm Thermoblocks were supplied through a local stockist and have been laid on a mortar bed with the special Marmox Multibond adhesive being used to seal the stepped joints between the units.

The Site Manager for Dobson Construction recounted: “The use of the Thermoblocks was specified by our project architect to tackle the issue of perimeter heat loss, around the perimeter of the basement and also at ground floor level, on top of the concrete wall. Our bricklayers carried out the work, using the Marmox adhesive and the installation went without any problems whatsoever.”
