Air bricks to suit all buildings and regulations

May 26, 2023 | Product News

Mould and internal air pollution can have long-lasting and highly damaging effects on a building and its inhabitants, which is why adequate ventilation is a legal requirement as per the Approved Document Part F.

To ensure your structures remain mould free and compliant, we supply a diverse range of air bricks here at Grayson, from plastic to non-combustible.

For those wanting a non-combustible solution

Constructed from sheet steel, all of our non-combustible air brick solutions comply with the latest fire safety regulations in Approved Document B, can be built into external wall types during construction and are easy to connect to ducting.

When supplied without a powder coating, these air bricks provide an unbeatable classification of A1. When supplied with a powder coating, they achieve a classification of A2-s1, d0.

Other key features and benefits of non-combustible air brick systems include:

• Available in a range of special paint finishes
• High flow terminal designed for powered ventilation systems offering low resistance to airflow and high resistance to fire
• Bezelled version for use with exterior cladding instead of brickwork
• Performance tested to BS EN13141-2:2010
• Available alongside a range of fire-rated accessories, including non-combustible ducting kits, grilles and weather louvres

For those wanting a plastic solution

The Timloc Air Brick is a robust ventilator ideal for use with cavity sleeves when ventilating through external walls and the 1201 and 1201XL telescopic underfloor ventilators when ventilating below suspended ground floors.

Manufactured by injection moulding in UV-stabilised polypropylene, the unique stepped front grille of this air brick provides unobstructed airflow and prevents the ingress of wind-driven rain, whilst the integral clips enable multiple air bricks to be stacked together to form 9″ x 6″ and 9″ x 9″ sizes.

Other key features and benefits of the Timloc Air Brick system include:

• Available in a range of colours to blend in with various brick types
• Very tough and robust
• Durable and totally resistant to decay
• Compliant with BS EN 13141-1:2004 (‘Ventilation for buildings’)
• Meets all relevant British Standards, satisfies all NHBC requirements and complies with all relevant Building Regulations
• Available alongside a range of purpose-made telescopic underfloor vent accessories, including three different extension sleeves (horizontal front, horizontal rear and vertical) and a duct adaptor

Fire safety made simple with the ARC Spandrel Barrier

Apr 4, 2023 | Product News

With the construction industry’s continued focus on fire safety, it’s imperative to utilise high-quality fire-separating elements in every single project.

To simplify this process, ARC Building Solutions have developed an eight-part solution to prevent the spread of smoke and flames and provide an effective seal at the party wall between semi-detached and terraced houses.

One of the key components of this fire preventive solution is the ARC Spandrel Barrier, which works to prevent fire from spreading between the party wall blockwork and the spandrel panel by sealing the top of the party wall cavity.

Developed with leading academia at Leeds Beckett University, this fire-preventative product has been trialled with major housebuilders and is proven to elevate the quality of your build.

Unbeatable fire protection  

Manufactured using rockfibre mineral wool, which achieves a fire classification of Euroclass A1 and conforms to BS EN 13162, the highly reliable ARC Spandrel Barrier creates a fire and thermal break which can provide:

• Up to four hours of fire integrity around the edge of the party wall
• Up to one hour of fire integrity between the spandrel panel and blockwork

By effectively preventing the spread of flames and smoke for up to four hours, ARC’s market-leading Spandrel Barrier ensures unbeatable fire protection for your building and its future residents.

Market-leading in more ways than one

Beyond creating a reliable fire break at cavity walls, the design and manufacture of the ARC Spandrel Barrier also provides a range of other invaluable benefits, including:

Easy installation

The lower-density section of the barrier is fitted into a cavity with compression, whilst the higher-density section sits on top of the party wall. The spandrel panel is then positioned on top of the Spandrel Barrier, making for an easy and rapid installation process.

Minimal heat loss

As well as preventing the spread of fire, this Spandrel Barrier also minimises thermal bypass. With building regulations requiring the limitation of heat loss to the external environment, using a product that ensures good thermal performance is essential.

Achieving zero U-value

Through effective edge sealing of the cavities, the ARC Spandrel Barrier also helps achieve a zero U-value when used in conjunction with the ARC T-Barrier, helping any building to pass the Standard Assessment Procedure (SAP).

Environmentally friendly

The materials used to make this Spandrel Barrier present no known threat to the environment, which means it is classed as ODP and GWP zero. The product has also been accredited A+ (the best environmental performance rating) by the Green Guide (which is part of the BRE Environmental Assessment Method).

Tired of de-tangling wire ties? Use our tangle-free alternative

Mar 14, 2023 | Product News

As one of the UK’s largest suppliers of cavity wall ties, with close connections to many of the country’s biggest house builders, we know a thing or two about these small yet vital metal ties.

Having spoken with many of our clients, we understand that de-tangling open-ended wire ties can take up vast amounts of your labourers’ time; time which can be wasted if the product is eventually thrown away. What’s more, the cardboard boxes that many ties are stored in can disintegrate when the weather (inevitably) takes a turn.

If you’ve grown tired of tangled ties and ruined boxes, it’s time to use the Grayson Tangle-Free Wire Ties, which offer a practical and cost-effective solution.

Why choose the Tangle-Free Wire Ties?

Suitable for masonry cavity walls, the Grayson Tangle-Free Wire Ties come in two variations: the Type 2 General Purpose Tie (for domestic houses and small commercial buildings of up to 15m) and the Type 4 Light Duty Tie (for domestic dwellings of up to 10m).

Both ties are available in multiple sizes (200mm-300mm) and are independently tested at Lucideon, so you can be sure you’re purchasing a trusted product with proven performance.

They also come with a range of other invaluable benefits:

• Tangle-free – Unlike competitor products, the Grayson Tangle-Free Wire Ties have closed ends, meaning batches of ties cannot get tangled together. With no time wasted ‘de-tangling’ your ties, more time can be spent on the job at hand.
• Incredibly safe – Besides being more practical, a closed-ended wire tie also makes the product much safer. That’s because there are no exposed ends to catch on passing items or people.
• Environmentally friendly packaging – The Grayson Tangle-Free Ties are not supplied in boxes as many wire ties are. Instead, they’re tied together in a tight, cardboard-free bundle. This provides a more environmentally friendly solution with very little waste and no disintegrating packaging in inclement weather.

For further details on the Grayson Tangle-Free Wire Ties or any of our other masonry metalwork products, contact your account manager on 08448 50 40 50.
