Toplite Standard

Toplite is a versatile aircrete material which is able to provide solutions below ground in foundation walls, in suspended beam and block floors and all types of internal and external walling situations. Its use provides many benefits for specifiers and contractors, making it the natural choice where blockwork is specified.

Toplite Standard Blocks combine low unit weight with high thermal insulation and acoustic performance, in strengths from 2.9 to 7.3N/mm2.  

Applications

  • Cavity inner leaves
  • Separating Walls
  • Solid Internal Walls
  • Higher Strength Loadbearing Walls
  • Solid External Walls
  • Cavity Walls below DPC

Benefits

  1. Low unit weight

    Most sizes of Toplite blocks meet the health and safety standars for single-person repetitive andling

  2. Fast building blocks

    Toplite blocks are light and easy to handle, decreasing build times

  3. Easy to work

    Cutting, chasing and finishing are all straightforward and quick to achieve using standard tools

  4. Range of strengths

    Range of options available for wide range of specifications

  5. Excellent thermal performance

    Toplite GTi offers a high level of thermal insulation contributing to low U-values

Application Details

General Purpose Walling

Toplite Standard can be used for all general-purpose walling applications including inner leaves, solid walls, internal partitions and walls below DPC.

Separating Walls 

Toplite Standard is recommended for use in separating walls including those comforming to Robust Details E-WM-6, E-WM-15, E-WM-23 and E-WM-24 as well as other key applications such as rendered outer leaf of cavity walls. 

Loadbearing Walls 

All Toplite products are produced to Category 1 manufacturing control as defined in BS 5628-1. This can provide an equivalent wall strength to that of conventional 10.4N/mm2 blocks produced to less rigorous category of manufacturing control.

Fire 

Toplite blocks provide excellent periods of fire resistance which can satisfy building regulations and other imposed requirements e.g. those by insurers. All Toplite products conform to a fire rating of Class A1 to BS EN 13501-1: 2002.

Sound Insulation 

Toplite blocks may be used to provide acoustic insulation between internal rooms to meet the requirements of Part E regulations for houses and flats.
