NEW

Stainless SteelAll Ancon and Staifix wall ties are manufacturedfrom Stainless Steel because of its corrosionresistance and its strength. The use of StainlessSteel means that no costly remedial measuresare required during the lifetime of the structure.

ApprovalsLook for these logos.

These products are approved by the BritishBoard of Agrément.

These products meet the technicalrequirements of the National House Building Council.

These products meet the requirements of Part E of the Building Regulations: Resistanceto the passage of sound. See pages 4-5 formore information.

AvailabilityAncon and Staifix wall ties are available frombuilders merchants throughout the UK. Fordetails of your nearest stockist please contactAncon on 0114 238 1 238.

SafetyAll Ancon and Staifix wall ties have speciallydesigned safety ends to reduce the risk ofinjury during handling and installation.

Correct InstallationWall ties should be pressed down in, andthen surrounded by, fresh mortar. In order toshow more details of the application, mortarhas been excluded from the photography inthis literature.

Part E of the Building Regulations

Type B for external walls wherea type A tie is not suitableThese ties must have a measureddynamic stiffness of <113MN/m3.

This logo indicates the ties with ameasured dynamic stiffness of<113MN/m3, that are suitable for use inexternal walls where a type A tie isunsuitable.

See pages 30-31 for more information.

Type A for separating orexternal wallsThese ties must have a measureddynamic stiffness of <4.8MN/m3.

This logo indicates the ties with ameasured dynamic stiffness of<4.8MN/m3. These ties are suitable foruse in separating (party) walls andexternal walls.

Ancon has tested its cavity wall ties toPart E of the Building Regulations:Resistance to the passage of sound. Part E aims to increase the soundinsulation of walls and, like many othermaterials, ties must now be tested ontheir ability to transmit airborne sound.

Independent tests have proven thatAncon has fixing solutions that meet thenew performance requirements for bothinternal and external walls.

Part E of the Building Regulationsclassifies wall ties into two types: Type Aand Type B. Two logos are shownthroughout this booklet to indicate theAncon and Staifix wall ties that meetthese new requirements.

Not all ties comply with Part E of the BuildingRegulations: Resistance to the Passage of Sound.

But Ancon and Staifix Wall Ties do.

See pages 30-31 for more information

Cavity Wall Ties

Type 1 Heavy Duty Wall Tie for buildings of any height

Type 2/3 General Purpose Wall Tie for buildings not greater than 15 metres in height

Type 4 Light Duty Wall Tie for buildings notgreater than 10 metres in height

for traditional brick/block construction

DD140 Part 2: Recommendationsfor the design of wall tiesDD140 Part 2 classifies ties according totheir strength and function. Anconrecommends that these classificationsare used to select the correct type of tieto suit your project.

Wall ties are an important element in thestability of cavity walls. The correctselection, spacing and installation of tiesis essential to avoid damp penetrationand the distortion or cracking of brickwork.

Many factors including cavity width, typeand height of building, and location mustall be considered in the selection of themost appropriate tie.

BS1243: Metal ties for cavitywall constructionBS1243 was withdrawn in 2005. Anconrecommends that wall ties are selected toDD140-2.

Selection of Wall Ties to DD140: Part 2

Installation of Ties

28

Wall ties should be pressed down in, and surrounded by, fresh

mortar. In order to show more details of the application, mortar

has been excluded from the photography in this literature.

To ensure cavity wall ties are effective at tying the leaves

together they should be installed as the inner leaf is constructed

and not simply pushed into a joint.

Ties should be installed with a slight fall to the outer leaf, never

towards the inner leaf as this could provide a path for moisture

to cross the cavity.

The drip part of the tie should point downwards and be

positioned near the centre of the open cavity. Ties with multiple

drips, like the Staifix RT2, can often be positioned centrally as

part of the drip will normally be near the centre of the open

section of a partial fill cavity.

Installed ties should be clear of mortar droppings to allow the

drip to function and prevent water from crossing to the inner leaf

of masonry.

For walls in which both leaves are 90mm or thicker, ties should be used at not less than 2.5 per square metre

(900mm horizontal and 450mm vertical centres). This spacing may be varied by building regulations. Ties

should be evenly distributed over the wall area, except around openings, and should be preferably staggered.

At vertical edges of an opening, unreturned or unbonded edges, and vertical expansion joints, additional ties

should be used. Such ties should be located at 300mm vertical centres, positioned not more than 225mm

from the edge.

Density and Positioning of TiesTypical Layout of Wall Ties Indicating Maximum SpacingStandard spacing for cavity brickwork 900mm x 450mm centres in a staggered pattern (2.5 ties per m2)

Wall ties should be of the correct length to ensure they are

properly embedded in the masonry. Ancon recommends tie

lengths which achieve an embedment of between 62.5mm

and 75mm.

A tie, 225mm long, would be the minimum length recommended

by Ancon for a 100mm cavity.

62.5mm + 100mm + 62.5mm = 225mm

The new Part E of the building regulations raises the performance

requirements of walls for resisting the passage of sound. The

aim is to offer increased protection to inhabitants against sound

from other parts of a building and from adjoining buildings.

Part E classifies wall ties into two types:

Type ATies for separating (party) walls or external walls

Type BTies for external walls where a Type A tie is unsuitable

Type A ties

These ties must have a measured dynamic stiffness of

<4.8MN/m3 taking both cavity width and tie density into account.

Test ResultsIndependent tests have proven the Staifix HRT4Housing Tie has a measured dynamic stiffness of<4.8MN/m3 at a 50mm cavity and is therefore suitablefor separating walls with cavities from 50mm to100mm at a standard density of 2.5 per m2.

Robust Standard Details

Robust Details Limited has approved the use of several standard

construction details as a means of complying with Part E when

building new houses and flats. Use of these details eliminates the

need for pre-completion sound testing. The Staifix HRT4 is suitable

for use with the approved details for masonry separating walls as a

Type A tie. For more information visit www.robustdetails.com.
