Peace of mind shouldn’t come at a price. With the upgraded 25/15 Channel, the only risk-free solution on the market, it doesn’t…

Incorrectly installing a brick tie channel can lead to more than an invalid warranty. It can threaten the integrity of your entire project.

Having worked as a proactive partner to those in the masonry sector for many years, we’re no strangers to redeveloping market-leading products to tackle concerns like these, and that’s precisely what we did with the high-strength 25/15 Channel.

After discussing the product with several valued customers, we discovered that some contractors were regularly fitting tek screws into any hole along the channel instead of the smaller holes as per manufacturing instructions.

This meant the channel was not being fixed in accordance with test data, thereby invalidating all warranties and, worst still, calling the integrity of the entire project into question.

 

The All-New 25/15 Channel

Challenge understood, we focused our attention on upgrading the existing channel to eliminate any risk during and after the installation process:

 

  • Contractors can now fix a tek screw through any hole within the channel, meaning it can no longer be incorrectly installed.
  • This also means that the warranty cannot be invalidated and the project cannot be compromised due to incorrect installation.
  • A risk-free solution gives ultimate peace of mind to installers, main contractors and anyone involved in the project.
  • With double the number of holes (every 55mm centres), contractors now also have more fixing options than ever before, giving greater versatility to a project.

Thanks to these transformative changes, we can confidentially say that no other competitor has a product like the fully tested 25/15 Channel.

In addition to being the only risk-free solution on the market, it’s also the only channel that requires just 8 fixings when installed to a Type 1 panel design, saving you money and labour on site.

Better yet, when ordered through Grayson, we guarantee:

  • Stable pricing for the next 9 months, helping you stay in control of your budget
  • The channel will be available for immediate delivery
  • Access to a full range of stainless-steel concrete screws (100mm – 300mm) and tek screws
  • GRP Compression Sleeves so as not to affect U-Values

Approved Document Part B Update : Section 10 ‘Resisting Fire Spread Over External Walls’.

Further to the December 2022 update to approved Document Part B, we are providing an update on the relevant guidance for our standard plastic ventilation products and non-combustible ventilation

products. Following the amendment to approved document Part B in England, all ‘Residential’ purpose groups have now been included within section 10 ‘Resisting Fire Spread Over External Walls’.

Approved Document B Volume 1: Dwellings (publishing.service.gov.uk)

The latest amendments restrict the use of combustible materials in external wall surfaces on all residential building’s over 11m high, or on any section of a residential building below 11m which is less than 1m from the relevant boundary.

The latest guidance will require non-combustible ventilation products, rather than our standard plastic ventilation products.

Building Type examples:

*Residential – House Building & Other Residential, Institutional or Hospitality (Wherever any persons will sleep overnight).

**Assembly, Recreation & any other building – eg. places of entertainment, work etc. (where people may congregate but do not sleep overnight).

Stay on schedule whatever the weather: FREE Grayson Brick Cloaks when placing your next stock order

Stay on schedule whatever the weather: FREE Grayson Brick Cloaks when placing your next stock order

Here at Grayson, we pride ourselves on sourcing and developing only the highest-quality products that make a genuine difference to our clients, and this is certainly one of them…

The Grayson Brick Cloak is an ultra-durable woven brick cover that protects brick stacks from water intrusion, is 100% reusable, and is currently FREE with all site orders.

While covering brick stacks with a muck board is common practice on many sites, this can lead to bricks becoming saturated with rainwater. When this happens, all work must be paused until the bricks dry out.

With the Grayson Brick Cloak, you can keep your bricks dry and your schedule on track in even the most severe weather conditions.

 

Long Lasting Protection

Made from an ultra-durable woven polypropylene material, the Grayson Brick Cloaks are 100% water resistant. When used to cover brick stacks, these covers:

  • Ensure that bricks do not become saturated with water and mud, meaning less time is wasted waiting for bricks to dry out
  • Reduce the risk of efflorescence, meaning less time is needed to clean bricks that have become discoloured

Not only do these high-quality cloaks help to keep your brickwork standards high and your build time fast, but they can also be reused day in, day out for up to 5 years.

 

Minimal Maintenance

You’ve already got a multitude of jobs to take care of when on-site, so why add more? Cleaning our Brick Cloaks is quick and easy as they do not react with water, acid, or commonly used detergents. They’re also non-toxic and won’t stain any of your other materials or equipment.

When not in use, these minimal maintenance, lightweight covers can be easily folded away until they’re needed again.

 

Improved Site Safety

With an increasing number of projects now stipulating that high-visibility covers must be used to protect any brick or stone stored on site, now is the time to move away from easily missed and unreliable muck boards.

The bright green colour of the Grayson Brick Cloak ensures that brick stacks remain highly visible. This is particularly useful as the winter months draw in and the number of daylight hours continues to drop.

 

Don’t Let Bad Weather Damage Your Progress

Place your brickwork sundry stock order today to receive FREE Brick Cloaks (minimum order applies). This offer runs until the end of November and is subject to availability.

Introducing FireBlox™: The all-new cavity fire barrier tested for use with SFS

Grayson FireBlox™ is a brand-new non-ventilated cavity fire barrier that has been fully tested for use with Steel Framing Systems (SFS) and comes with a market-leading A1 fire rating.

Designed for use within external wall cavities of up to 600mm, the foil encapsulated Fireblox™ is suitable for a wide range of sector applications and on-site uses, including the junction of compartment floors and around openings.

What’s more, the product can also be supplied with an integral damp proof course, helping to save additional procurement and installation costs.

Robust fire resistance for up to 120 minutes

FireBlox™ has undergone rigorous testing to ensure it provides a high level of insulation while also preserving the integrity of the building structure in the event of a fire.

Thanks to the product’s class A rating, it provides up to 120 minutes of fire resistance when used within external cavity walls, and has been tested for use in conjunction with masonry support brackets.

Testing has also been carried out to ensure the effectiveness of FireBlox™ within SFS systems with calcium silicate fibre cement boards.

Easy installation

Alongside its versatility and high fire resistance, the FireBlox™ is also extremely easy to install, saving you on-site labour costs and helping you to avoid unnecessary delays to your project.

Whilst the exact installation process varies depending on the cavity size (and whether the product is installed vertically or horizontally), FireBlox™ comes in 605 x 1000 x 100mm deep slabs and requires only 5mm of compression when fitting. It can be easily cut to size on site to suit your cavity.

Best of all, installing the FireBlox™ doesn’t require any specialist equipment, simply:

  • A masonry drill and drill bits to suit the fixings
  • A screwdriver and stainless screws
  • A measuring tape
  • A saw or knife for cutting

Once installed, no active maintenance is required for the FireBlox™, providing peace of mind that the structure will stay protected in the event of a fire.

Futureproofing your projects: Keep air, vapour and fire under control with the reinforced Visqueen A2 Vapour Barrier

Futureproofing your projects: Keep air, vapour and fire under control with the reinforced Visqueen A2 Vapour Barrier

In modern day construction, a vapour barrier must go beyond simply restricting the passage of moist air within floor, wall and roof constructions.

With fire safety an ever-increasing cause for concern, it must also help safeguard building inhabitants from the preventable spread of fire, and that’s precisely what the Visqueen A2 Vapour Barrier does.

By working to keep air, vapour and any possible fires under control, this reinforced aluminium control layer helps to futureproof your building projects in more ways than one.

Why choose the Visqueen A2 Vapour Barrier?

The Visqueen name has long been recognised as one of the leading manufacturers of advanced membrane technologies, and it’s not hard to see why.

Visqueen

The design and manufacture of the A2 Vapour Barrier ensures a number of market-leading benefits, including:

 

  • Reduced interstitial condensation – Thanks to the A2 Vapour Barrier’s multi-layer aluminium structure, it can effectively reduce the risk of interstitial condensation occurring, thus protecting the wooden and metal elements of a building.
  • Greater fire protection – With a high fire classification of A2 – s1 d0, this product is completely non-combustible and produces little to no smoke and no flaming droplets during combustion. This ensures both the structure and any building inhabitants are better protected.
  • Versatile application – Suitable for use within floor, wall and roof constructions, the Visqueen A2 Vapour Barrier can be used across multiple projects for humidity classes 1, 2, 3, 4 and 5. This versatility makes for a much simpler procurement process.
  • Easy installation – Unlike other vapour control layers on the market (which are folded), this product is supplied in single wound rolls, making for easy and rapid installation on site.

Approvals and Standards

Our focus here at Grayson has always been procuring the highest quality construction consumables from the most reputable manufacturers, so it will come as no surprise that approvals and standards are important to us.

Unsurprisingly, the Visqueen A2 Vapour Barrier comes with multiple seals of approval:

  • Achieves a reaction to fire classification A2 – s1, d0 to BS EN 13501-1:2018
  • BS 5250:2021 Management of moisture in buildings – code of practice
  • UKCA CE UKNI Mark EN 13984:2013
  • Quality Management System ISO 9001:2015
  • Occupational Health and Safety System ISO 45001:2018
  • Environmental Management System ISO 14001:2015

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:

2000 Range Wall Tie

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

Notes:
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.
