Blockwork solutions Durox is a modern construction material, whose versatility, light weight, thermal and acoustic properties make it the ideal solution for a wide variety of applications in all types of building. Blockwork solutions For more detailed product applications, please see pages 16-24 Walls – standard mortar Cavity inner leaves, solid external walls and internal walls Coursing bricks Separating walls Supabloc 4 Supabloc 7 Supabloc 8 Coursing bricks Higher strength loadbearing walls Supabloc 4 Supabloc 7 Supabloc 8 Coursing bricks Cavity inner leaves, solid external walls and internal...

Blockwork solutions Blockwork solutions Durox can be used below ground in foundation walls, in suspended beam and block floors and in all types of internal and external walls. It provides many benefits for specifiers and contractors making it the natural choice where blockwork is specified. Note the paint stripe system of block identification is being superseded with ink jet codes, effective after September 2014. See the Block Identification section on page 30 for further details. 01 Easy to work Cutting, chasing and finishing are all straightforward and quick to achieve using standard tools. 02 Excellent...

Blockwork solutions Durox Supablocs combine low unit weight with high thermal insulation and acoustic performance, in strengths of 3.6, 4.2, 7.3 and 8.7 N/mm2. Note the paint stripe system of block identification is being superseded with ink jet codes effective after September 2014.

Durox Coursing bricks used to avoid thermal bridging and minimise wastage. Durox Coursing slips for use with Floor blocks to reduce thermal bridging. Reduced thermal bridging Reduced thermal bridging Minimises thermal bridging maximises efficiency Minimises thermal bridging maximises efficiency Less wastage Less wastage Ideal for infilling over lintels and between floor joists Ideal for infill beneath Durox Floor blocks at the perimeter walls Coursing bricks are designed for use with the range of Durox blocks and should be used to avoid thermal bridging and minimise wastage. Coursing slips are specifically...

Transverse load Durox Floor blocks used in ground floors to reduce the U-value and minimise wastage. The blocks have been tested spanning 530mm and 620mm to sustain a point load of 3.5KN transferred via a 100mm x 100mm steel plate. Thermal insulation The use of Durox Floor blocks may reduce the amount of ground floor insulation needed compared to the use of denser floor blocks. This will be further improved when used in combination with Durox Foundation blocks. For examples please visit www.tarmacbuildingproducts.co.uk Applications Durox Floor blocks are suitable for use in beam and block suspended...

Aircrete applications TBP aircrete blocks are suitable for a wide range of applications. Separating walls The Building Regulations require separating walls to provide reasonable resistance to sound transmission. Guidance on suitable Durox and Toplite constructions capable of meeting the specified performance given in Approved Document E is shown on 18-21. This includes constructions that can be built to satisfy Robust Details E-WM-6, E-WM-10, E-WM-13, E-WM-15, E-WM-23 and E-WM-24. The use of Robust Details provides an alternative to pre-completion testing for demonstrating compliance with Part...

Internal walls* Any grade of Durox or Toplite can be used for the construction of internal walls. Internal floors* Approved Document ‘E’ prescriptive solutions or TBP constructions which have been shown by testing to meet the regulations. For partitions in dwellings, these products can be used to provide good levels of airborne sound insulation as well as a suitable background for fixings and finishes. Approved Document E requires that internal floors in dwellings provide the minimum sound insulation of 40RwdB. Durox and Toplite Floor floors have been shown to exceed this standard. For commercial...
