Thermal Lightweight Aggregate (TLA)

What is TLA?

Thermal Lightweight Aggregate is a free-flowing, pourable insulation combining coated EPS beads with cement and water

Its free-flowing properties provide a faster and more efficient way of installing insulation, which makes it suitable for many different applications. At Co-Dunkall Ltd we are proud to be East Anglia’s only approved installers of this innovative product, and believe it to be truly re-defining in the world of construction.

Applications of TLA

Subfloor

TLA is a high-performance pourable insulation. It can be laid directly on to compacted hardcore and provides enhanced U-Value and Psi-values compared with traditional floor build-ups of the same thickness.

With a faster install, drying time of 48 hours and reduced risk of thermal bridging, TLA is a flooring solution with maximum efficiency.

Timber Frame

TLA is a cement based pourable insulation which provides a level base without camber. By replacing traditional floor systems with TLA, it is possible to save significant weight whilst still meeting the loading requirements of the floor.

TLA has lightweight, thermal and acoustic benefits which can lead to savings on structural design.

Roofing

The unique combination of strength and insulation forming this product reduces the layers required in roof design, and therefore materials needed. This not only saves you on the cost of materials but also waste management, time and labour costs.

Although this product is liquid in state, it can also be installed at varying depths and angles therefore allowing for falls.

Underfloor Heating

Due to its void filling, free-flowing form, this creates a single continuous thermal layer, meaning no gaps down the sides for heat loss like with insulation.

The robust platform provided by this product leads to more responsive heat up times resulting in lower energy bills for the end-user. This is aided by the EPS beads.

What are the advantages?

Flexibility: TLA can be adapted for a variety of solutions to meet requirements on thickness, weight and thermal performance to name a few
Efficiency: One team can install 1000m2 + per day allowing for increased productivity on site
Zero waste: When batched to the exact requirements for a specific project, TLA is a zero-waste product. No offcuts are produced or skips are required meaning a reduction in your waste management costs
A2 fire classification: TLA has an A2 Fire classification meaning it has limited combustibility
High strength: TLA has a strength of 750KPa, meaning a thinner finishing screed is required
Lightweight: Installed density as low as 130kg/m3 and in some cases can provide a solution up to 10 times lighter than traditional solutions
Rapid drying times: It dries at a rate of 1cm per day which is up to 10 times faster than alternative methods. With rapid drying times, follow on trades can work more quickly resulting in an improved build programme
Reduced thermal bridging: Reduced risk of thermal bridging due to it’s enhanced Psi values. Insulates all areas with no voids

 Trustindex verifies that the original source of the review is Google. I did screed with them twice, we had our house done in 2 phases and in the 1st phase they supplied us with specific stats, on the 2nd phase they supplied us with different stats model and a control box which allows to connect to them remotely but, then I had an issue with the phase 1 stats won't connect to the system as they don't support that functionality. I rang their customer support and explained the issue, they offered to swap the phase 1 stats with new ones so, all stats will be from the same model and all will connect to the control box.
One more word about their expertise, the 2 phases were done a part so the 1st phase screed was higher than the existing old bit, when they came to do the old bit on the 2nd phase, I asked if they can do the screed so that both bits will be same height, they did it perfectly, both phases met up level and the wood floor on top is at the same height, I must say I was sceptic but, these guys are awesome, they are experts in what they do. that made me so happy!
That is a company who cares about their business and about their customers.
I will definitely recommend and will definitely do business with them again.
Thanks you Co-Dunkell

 Trustindex verifies that the original source of the review is Google. We had our screed pumped in and laid by the team at Co-Dunkall today at our self-build, the three man team onsite and those in the office were all professional and friendly at all stages from quotation, survey and the final delivery and instation. Everyone has done what they said they would do and within the timescale given. If you need pumped floor screed I can recomend this company 100%

 Trustindex verifies that the original source of the review is Google. We had Co-dunkall provide a cemfloor screed for an outbuilding which needed the floor raising. Thoroughly professional service 3 survey calls and inspections prior to the job. Nikki and the office team all highly knowledgable on so many aspects and on the day they even provided a 6 wheel mini mix to accommodate the property complexities. Good follow up and so pleased for a  very clean and tidy washout considering how messy the job can be. You would not know they had been on site. End result is exactly what we needed
