Extra-long cavity wall ties

Extra-long cavity wall ties

As the materials used within cavity walls continue to change in response to new and updated building regulations, so too does the size of the cavities themselves.

Over the years, we’ve seen a substantial increase in demand for longer cavity ties here at Grayson, which is why we stock Type 1 ties in 325mm and 350mm as standard.

These extra-long cavity wall ties, made of high-grade austenitic stainless steel, provide our customers with a high load-bearing solution to building stability and are available for next day delivery.

Expertly engineered

The 2000 Range Wall Tie, which includes the extra-long 325mm and 350mm sizes, has been expertly engineered by ACS to be sufficiently safer than all other formed ties on the market today.

What’s more, the manufacturers have incorporated a range of other innovative design features to aid the installation process:

Additional benefits include:

  • An integrated drip feature that provides advanced water and moisture dissipation, even in angles of up to 5°.
  • The product is fire-rated Class A1, making it ideal for non-combustible cavity requirements.


Do I need extra-long cavity ties?

With the England and Wales Building Regulations* now allowing for cavities up to 300mm in width, it’s no surprise that increased cavity sizes are becoming more prevalent in the industry.

*Approved Document A, Table 5, Cavity Wall Ties

1. Where face insulated blocks are used the cavity width should be measured from the face of the masonry unit.
2. The embedment depth of the tie should not be less than 50mm in both cases.
3. For cavities wider than 175mm calculate the length as the nominal cavity width plus 125mm and select the nearest stock length. For wall ties requiring embedment depths in excess of 50mm, increase the calculated tie length accordingly.

Based on the latest regulations, our extra-long wall ties are best suited to projects where two masonry walls are separated by a nominal cavity width of at least 176mm.

Futureproof your build with the UK’s first fire-rated sealing system

Futureproof your build with the UK’s first fire-rated sealing system

The inclusion of fire safety measures in the early stages of a construction project is one of the most effective ways to minimise fire risks and protect lives. This includes using high-performing fire-rated membranes to seal vulnerable interfaces like windows, balcony doors, and parapets.

At Grayson, we supply several quality membranes and adhesive pastes that when used together, provide stability and integrity in case of a fire.


The Grayson fire protection range

The flexible fire-rated membranes are used for sealing interfaces on construction projects. Made from coated glass fibre, they provide a strong bond to most common building substrates when used alongside the suitable adhesive pastes.

Depending on the building regulations that apply to your unique construction project, we supply two ranges that achieve different fire classifications:

two ranges that achieve different fire classifications

Beyond combustibility

The durability of a building depends on more than just fire resistance. When building for both safety and longevity, it’s essential to use fire-safety products that also consider:

  • The movement of air
  • The movement of moisture
  • The effects of UV radiation

In addition to its high fire classification, these systems also provide an airtight and weathertight seal and high UV resistance. This makes it a quality alternative to standard EPDM membranes, which can degrade under solar UV radiation.

High strength sliding anchors from Grayson

High strength sliding anchors from Grayson

Available in 8 variations


When sourcing sliding anchors for your next project, it’s essential to find a manufacturer that has considered three core elements: strength, movement, and versatility.

The product must transfer lateral load from the masonry to the primary structure whilst allowing for differential movement. It must also come in a range of fixing styles, stem lengths, and head dimensions to suit your unique project.

At Grayson, we work closely with a leading manufacturer of structural building components who have developed a sliding anchor range that ticks all three of these core element boxes.

Better yet, when ordered directly through Grayson, these high-grade austenitic stainless-steel fixing restraints can be manufactured to your bespoke requirements and quickly delivered to site.


The versatile sliding anchor range


Versatility is at the very core of this sliding anchor range. Not only can all anchors be tied back to both structural steelwork and concrete, but each anchor has also been expertly engineered to suit a slightly different application –

Order bespoke, high strength sliding anchors through Grayson for fast on-site delivery


Beyond a range of fixing styles, these sliding anchors also come in various stem lengths. While standard sizes range from 300mm to 650mm, non-standard lengths are also available (as is the option to alter stem head dimensions and hole positions).

To ensure that your anchors suit your unique requirements, simply ask a member of our friendly team about a bespoke anchor design. Thanks to our close working partnership with the manufacturer, even bespoke anchors can be manufactured and delivered to site quickly.


Did you know we supply OWT and TWT ties?


As is standard practice, these sliding anchors are used in conjunction with one-way (OWT) and two-way (TWT) ties which allow vertical movement whilst also providing lateral restraint.

We stock a range of OWT and TWT ties here at Grayson that move up and down the stem to suit the masonry coursing. These ties start at 100mm lengths for the one-way tie, and 200mm for the two-way tie, and increase in 25mm increments.


For further details on this sliding anchor range and supporting OWT and TWT ties, contact your account manager on 08448 50 40 50.

Protect against wind-driven rain with the BBA approved expanding foam tape

Protect against wind-driven rain with the BBA approved expanding foam tape

When it comes to sealing window reveals and other construction joints, traditional methods like sealant and backer rods often fail to sufficiently protect against wind-driven rain.

Here at Grayson, proof of performance has always been of the utmost importance to us, which is why we stock only BBA approved expanding foam tape that meets the stringent requirements of DIN standards.

Designed specially for sealing construction joints in buildings up to 100m high, this versatile and vapour permeable tape protects against wind, dust, and driving rain up to 600 Pa (equivalent to wind force 11).


Versatile application


The Grayson expanding foam tape is available in 8 different thicknesses, meaning it can sufficiently seal and protect joints that range from 1mm to 42mm in size.

This makes it suitable for a wide range of applications, including sealing joints in areas such as:

  • Door and window installations (including skylights)
  • Steel and timber-framed buildings
  • Prefabricated concrete
  • Modular constructions
  • Cladding panels and curtain walling

Once applied, this self-adhesive and pre-compressed foam expands into the cavity gap, creating an effective seal. At 0% compression, it is suitable for debris sealing. At 75% compression, it can protect from 70mph wind-driven rain.


Well-designed means high standards


Despite being designed predominantly as an elastic weather seal, the advantages of the Grayson expanding foam tape extend beyond driving rain protection.


This includes:

  • Fire-resistance – The material is impregnated with fire-resistant polymeric dispersion
  • Warmth and sound – The tape possesses outstanding thermal and acoustic characteristics
  • Longevity – Permanent elasticity means a long-term life expectancy

All of these unique design qualities make for a product that complies with the most stringent of requirements, including:

  • DIN 18542 edition 2009 DIN 18055
  • ISO 9001
  • CE-Certified

Coloured Timloc Airbricks: Ventilation that blends in no matter the project

Coloured Timloc Airbricks: Ventilation that blends in no matter the project

Coloured Timloc Airbricks

Obstructed airflow within hollow floors can wreak havoc on timber joists and floorboards, particularly in the winter when rooms cool and central heating kicks in.

As with all condensation-related problems, ventilation is the only treatment.

With the Timloc Combination Airbrick, you can create clear airflow passages to these void spaces and significantly reduce further moisture by preventing the entry of wind-driven rain.

Sold in a range of colours, this robust, durable, and decay-resistant solution is available in large stocks here at Grayson.


Unique Design Benefits

The Timloc Combination Airbrick has been designed with several unique features and subsequent benefits. Whilst the stepped front grille provides unobstructed airflow and prevents the ingress of water, the integral ‘clip together’ facility allows multiple bricks to be stacked to form 9” x 6” and 9” x 9” sizes.

This is hugely beneficial where larger than average ventilation is required, such as in large residential homes and period industrial and commercial premises.

The airbrick is also available in multiple colours, meaning it can blend in with a range of brick types across a range of projects. This includes:

Coloured Timloc Airbricks

Versatile Uses

The versatility of the combination airbrick extends beyond vent size and brick colour.

When used in conjunction with cavity sleeves, it provides natural air ventilation through external walls to a building interior.

Alternatively, when used with the Timloc Telescopic Underfloor Airvent (which can be adjusted vertically between three and five brick courses), it can also be used to ventilate below suspended ground floors.


Quality Standards

  • 6.5mm wide front grille opening complies with BS 5440 Pt 2 and British Gas requirements
  • Satisfies all NHBC requirements
  • Manufactured to BS EN ISO 9001 and BS EN ISO 14001
  • Complies with all relevant Building Regulations and meets all relevant British Standards
  • Equivalent area marking to the front face is compliant with BS EN 13141-1:2004
