Thin Joint Systems - Use of the Celcon Thin Joint Systems in Walls and Foundations

The Celcon Thin-joint system can be used for many forms of construction:

• Cavity Walls
• Solid External walls
• Partitions
• Separating Walls
• Foundations
• Thin Joint System in Extensions
• Applications of Thin Joint Systems

Cavity Walls

When building with the Thin-joint system, the inner leaf of blockwork can be built first taking the outer leaf off the critical path of the build programme. This enables internal work to proceed whilst the outer leaf is being constructed, enabling easier inspection of the cavity and simple installation of any insulation required.

Solid External Walls

Applying Celfix Mortar with either a ‘scoop’ or alternatively with a ‘sledge’, which is specifically designed for use with solid wall construction, allows the superstructure of a dwelling to be completed in 2-3 days. The Thin-joint system offers the designer a choice of solutions with the benefits of both strength and thermal insulation. The use of thin-joint techniques gives greatly improved U-values of up to 20% and can meet thermal regulations without the need for additional insulation.

Partitions

Ideally suited for the construction of partition walls, the Thin-joint system adds to the existing benefits offered by Celcon blocks, which include excellent sound insulation and high fire resistance. With the speed of build and the mortar setting more quickly, it is possible for the walls to be plastered without delay.

Separating Walls

Separating and flanking walls constructed with the Thin-joint system satisfy the sound insulation requirements of the National Building Regulations. For further details see Agrément Certificate 01/3816 or contact our Technical Services Department.

Foundations

Celfix Mortar is suitable for use in classes DS1 and DS2 soil and groundwater conditions, as defined in Table 2 of BRE Special Digest 1 - Concrete in aggressive ground Part 1:2001.

Thin Joint System in Extensions

Whether the wall is solid or cavity construction, the Thin-joint system is ideal when building extensions. The inherent speed of build enables quicker construction times, excellent thermal efficiency, reduced wastage of blocks and mortar, and a potentially cleaner site.

Applications of Thin Joint Systems

• Internal and external leaves in cavity walls
• Solid walls
• Separating / party walls
• Flanking walls
• Partitions
• Multi-storey
• Foundations
