6 AIRTEC XL Wall Block AIRTEC XL 2.9N blocks have been designed to offer the very best thermal performance of the Airtec product range and as a cost-effective solution to the ever-increasingly stringent requirements of Part L of the Building Regulations. This allows the builder to minimise the amount of secondary insulation required to meet thermal regulations as well as meeting the strength requirements of the very latest UK building codes. An inner leaf of Airtec XL blocks gives the builder the option of using a 75mm cavity, either partiaWy-fiWed or fuWy-fiWed whilst still achieving a U-Value...

7 AIRTEC STANDARD Wall Block AIRTEC STANDARD 3.6N blocks have been designed to offer the superior thermal performance of Airtec blocks along with the structural capacity for up to 3 storey construction. In fact Airtec Standard blocks offer the same thermal conductivity value of a typical 2.9N strength aerated block. This gives a combination of medium strength and high thermal performance in one block, offering flexible design for single storey and multi-storey build. This product is exceptionally low weight for an aerated block of this size and in this strength category. APPLICATIONS External...

8 AIRTEC PARTY WALL Block AIRTEC PARTY WALL 3.6N blocks have been designed to offer both the superior thermal performance of Airtec blocks along with a specification suitable for acoustic party/separating walls. Airtec Party Wall blocks can be used in Robust Detail party wall constructions between dweWings and when building in accordance with Part E of the Building Regulations. APPLICATIONS TECHNICAL PROPERTIES Party/Separating Walls to Part E Օ Robust Standard Dtail Party Walls Flanking walls to Party walls 镕 ThinJoint Construction Fire resistant walls Face Size: Compressive Strength (min):...

9 AIRTEC SEVEN Wall Block AIRTEC SEVEN 7.3N blocks have been designed to offer the highest structural capacity of the Airtec range for construction up to 3 storeys in line with current Building Regulations and Structural Codes. In addition, the low weight of these blocks and ease of handling offer the builder a quick, easy and cost-effective method of construction. The builder also benefits from the superior thermal properties of Airtec products that allows for easier design to meet Part L requirements. APPLICATIONS TECHNICAL PROPERTIES External Cavity or Solid watts Loadbearing and non-loadbearing...

10 AIRTEC FOUNDATION 140 Block AIRTEC FOUNDATION blocks are designed as a lightweight, speedy and cost effective alternative to traditional cavity foundation walls. A solid Airtec foundation wall of 140mm high blocks built two courses high means a faster build, shallower trenches, less waste material, no need for cavity wall ties, less mortar and eliminates any chance of collapsed cavities. The excellent thermal properties of Airtec Foundation blocks enhance thermal integrity throughout the building especially when used in conjunction with Airtec walls and floors. Hand-holds are provided for...

11 AIRTEC FOUNDATION 215 Block BBA; AIRTEC FOUNDATION blocks are designed as a lightweight, speedy and cost effective alternative to traditional cavity foundation walls. The 215mm height block is offered as an alternative to our 140mm high type for builders wishing to use conventional coursing height blocks. The excellent thermal properties of Airtec Foundation blocks enhance thermal integrity throughout the building especially when used in conjunction with Airtec walls and floors. Hand-holds are provided for improved ease of handling and safety. APPLICATIONS Solid Foundation Walls below dpc...
