Blown Bead and Loft Roll Beccles — Your Insulation Options

We offer two core insulation methods, and many properties in the Beccles area benefit from both.

Blown bead insulation is used to fill or top up cavity walls. Small holes are drilled into the outer leaf of the wall, and polystyrene beads are injected under pressure until the cavity is fully filled. The holes are then made good. It is a fast, minimally disruptive process — most domestic properties can be completed within a day — and it delivers an immediate improvement to the thermal envelope of the building.

Loft roll insulation is laid between and across ceiling joists to the recommended depth (currently 270mm for most dwellings). If your existing loft insulation is thin, compressed or patchy, topping it up to the correct depth is one of the most cost-effective energy-efficiency measures available for older Norfolk homes.

We source our insulation materials through Eastern Insulation Supplies, so we control both supply and installation — which keeps lead times short and pricing straightforward.

Why Choose a Local Beccles Specialist

Beccles has a mix of Victorian terraces, 1960s–1980s estate housing, and newer builds — each with different insulation needs. Older solid-wall properties may not suit cavity fill, while post-war cavity-wall homes are often ideal candidates for blown bead. We assess the property first and advise honestly on what will and won’t work.

Being based in East Anglia means we know the local housing stock well. We are not a national call-centre operation sub-contracting to whoever is available — our team carries out the work directly, and we’ve been doing so across Norfolk and Suffolk since 2008.

Areas Around Beccles We Cover

We regularly work in Beccles itself and throughout the surrounding area, including Lowestoft, Great Yarmouth, Bungay, Halesworth, Southwold, and across to Norwich. We also cover Ipswich, King’s Lynn, and Bury St Edmunds — wherever there is insulation to be installed in East Anglia, we can help.

Frequently Asked Questions

How long does blown bead cavity wall insulation take?

Most standard domestic properties in Beccles can be completed in a single day. Larger or more complex builds may take a little longer, but we will confirm the expected timeframe before work begins.

Is my home in Beccles suitable for cavity wall insulation?

Properties built from the 1930s onwards typically have cavity walls and are good candidates. We carry out a survey to check cavity width, wall condition, and exposure before recommending blown bead. Some older solid-wall buildings are not suitable — we will tell you upfront if that is the case.

Can you supply insulation materials only?

Yes. Through Eastern Insulation Supplies we can supply loft roll, blown bead, and other insulation products for trade and self-build customers across Norfolk and Suffolk.

Do you also install underfloor heating and screed?

We do. Co-Dunkall is primarily known as East Anglia’s leading floor screeding contractor — liquid screed, sand and cement screed, and underfloor heating are our core services. Insulation often forms part of a wider floor build-up, and we handle the full package.

 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
