Blockwork solutions Toplite is a versatile aircrete material which is able to provide solutions below ground in foundation walls, in suspended beam and block oors and all types of internal and external walling situations. Blockwork solutions Walls Cavity inner leaves, solid external and internal walls Toplite Coursing bricks Separating walls Toplite Standard Toplite ‘7’ Toplite Coursing bricks Higher strength loadbearing walls Toplite ‘7’ Toplite Standard Toplite Coursing bricks Solid walls below dpc Toplite Foundation Cavity walls below dpc Toplite GTi, (inner leaf only) Standard or ‘7’...

Blockwork solutions Blockwork solutions Toplite can be used below ground in foundation walls, in suspended beam and block oors and in all types of internal and external walls. Its use provides many benets for speciers and contractors, making it the natural choice where blockwork is specied. 01 Low unit weight Most sizes of Toplite blocks meet the health and safety standards for singleperson repetitive handling, helping protect construction workers from injury. 02 Fast-build blocks Toplite blocks are light and easy to handle, decreasing build times. Excellent technical performance • Toplite...

Blockwork solutions Toplite GTi, Standard and ‘7’ Blocks combine low unit weight with high thermal insulation and acoustic performance, in strengths from 2.9 to 7.3 N/mm2. Loadbearing walls Toplite ‘7’ is suitable for more demanding loadbearing applications whilst retaining the characteristic low unit weight of aircrete. Toplite ‘7’ is typically used in the ground oor of 3 storey housing in accordance with Approved Document A. It may also be used in separating walls including those conforming to Robust Details E-WM-6, E-WM-15, E-WM-25 and E-WM-24. All Toplite products are produced to...

Toplite Coursing bricks are designed for use with the range of Toplite blocks, to avoid thermal bridging and minimise wastage. 65mm width Reduced thermal bridging Minimises thermal bridging maximises efciency Less wastage Ideal for inlling over lintels and between oor joists Application Toplite Coursing bricks should be used for general coursing work, inlling small areas of wall such as those between timber oor or roof members as well as sills and over lintels. Their use will eliminate cutting and wastage. Table 7: Size and unit weights (kg) Block width (mm) Notes Unit weights, which are...

Toplite Floor blocks provide fast installation and effective thermal and acoustic insulation. Transverse load The blocks have been tested spanning 440 and 535mm to sustain a point load of 3.5KN transferred via a 100mm x 100mm steel plate. Applications Toplite Floor blocks are suitable for use in beam and block suspended ground and internal oors in single occupancy dwellings under domestic loading. Where high point loading is anticipated, such as in garages, a reinforced structural topping must be used. Where the oor loading dictates closer beam spacing, a 440 x 215 x 100mm Toplite Standard...

Aircrete block 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 specied performance given in Approved Document E is shown on pages 16-19. 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...

Separating walls The Building Regulations require separating walls to provide reasonable resistance to sound transmission. New dwellings – Robust Details E-WM-6* (conventional mortar) 2 x 100mm Durox Supabloc 4, 7 or 8, or Toplite Standard or 7, minimum 75mm cavity, plasterboard (nominal 8kg/m2) on dabs on cement/sand render with scratch nish. E-WM-10* (thin joint mortar) 2 x 100mm Durox System 600 or 700 minimum 75mm cavity (using Ancon Staix HRT4 or Clan PWT4 wall ties), plasterboard (nominal 8kg/m2) on dabs on cement/sand render with scratch nish.

Internal walls* Any grade of Durox or Toplite can be used for the construction of internal walls. Internal oors* 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 xings and nishes. Approved Document E requires that internal oors in dwellings provide the minimum sound insulation of 40RwdB. Durox and Toplite Floor oors have been shown to exceed this standard. For commercial and...

Walls below DPC Durox and Toplite products can be used to construct walls below ground. External walls Durox and Toplite blocks may be used to construct cavity and solid external walls. TBP products can be used in sulphate soil conditions as shown in Table 11 and as conrmed by British Board of Agrément Certicate No. 00/3776 and 12/3896. In addition, they are resistant to the freeze/thaw conditions likely to occur below the DPC, as conrmed by tests to MOAT 12. For cavity construction, the minimum leaf thickness will normally be 90mm. Durox or Toplite blocks are suitable for a range of...
