Purlin zone — completed
The hardest part of any asbestos roof to seal. The finished layer follows every purlin and sheet lap continuously, with no gaps left at the structural junctions.
Seal the asbestos cement roof over your commercial building — without stripping it. Enverge closed-cell spray foam is applied to the underside of the sheets from £15/m² fully installed: fibres locked in, condensation drip gone, insulation added in one visit.

If your Nottingham commercial building still has an asbestos cement roof, removal is rarely the only answer. Where the sheets are in sound condition, encapsulation is explicitly recognised under the Control of Asbestos Regulations 2012 as a valid management option — and Enverge spray foam seals the underside while adding the insulation the building never had.
This is a commercial roof service only — asbestos cement roof sheets, sealed from the top side or the underside, never walls, soffits or internal surfaces. Duratite issue the specification and supply the Enverge system, UKATA-trained operatives carry out the work across every Nottingham postcode, and the finished roof is backed by a 25-year manufacturer-backed product warranty on Nexseal LE. We regularly survey and work on buildings around Castle Marina, Lenton, Beeston.

Fifty-year-old cement sheets weather from the surface down. Fibres work loose at the fixings, the laps and the exposed faces — and the sheets run cold enough to rain condensation on everything underneath. Encapsulation deals with both problems at once.
Removal is the right answer when sheets are friable, badly damaged, or the building is coming down. Everywhere else it buys you weeks of scaffolding, licensed works and a waste bill to end up with the roof you already had. Encapsulation seals the fibres where they are, adds the insulation the building never had, and is done in days — and if your roof genuinely needs stripping, the survey report says so.

Underside encapsulation in Nottingham typically costs £15 to £35 per m² fully installed at standard 25–50mm thickness — one figure covering materials and professional application. Strip-and-recover on the same roof usually lands between £55 and £90 per m².
| Complete system, fully installed | Typical installed price | Best suited to |
|---|---|---|
| Enverge underside encapsulation — 25–50mm | £15–£35 / m² installed | Sound asbestos cement roof sheets sealed from inside, insulation gained |
| Where the lower end applies | from £15 / m² installed | Open, accessible roof areas with clear internal access |
| Strip-and-recover, for comparison | £55–£90 / m² stripped-and-recovered | Friable or badly damaged sheets, or a building being redeveloped |
One system, one price. Every element below is part of the installed figure — none of them is ever priced separately.
Sealing the underside does three things at once: it locks loose fibres into a continuous self-bonded layer, it warms the sheet above dew point so condensation stops dripping, and it gives the building a real insulated envelope for the first time.
Because nothing is fixed through the sheets and nothing is removed, the roof structure is never disturbed — which is exactly why the manufacturer will stand behind the product for 25 years.
Closed-cell foam bonds to every corrugation on the underside, locking the surface down so fibre release at fixings, edges and weathered faces stops.
Asbestos cement runs cold and wet all winter. Encapsulation warms the internal face above dew point, so the drip onto stock and plant stops for good.
The same pass that seals the fibres delivers a Part L-grade insulated envelope — a benefit a strip-and-recover only gets by buying a whole new roof.
Method, product data and photographic record are handed over so the works can be recorded against the asbestos register as a management action.
Four steps from first call to warranty. Most Nottingham roofs are surveyed within 2–5 working days and sealed in a single visit.
A condition assessment of the asbestos cement sheets on your Nottingham building, with photographic record and an encapsulate-or-remove verdict in writing.
Same-week quotation with measured areas, the specified thickness and a bespoke U-value calculation for the new build-up.
Work zone contained and monitored, then the foam is applied to the underside to the specified thickness by UKATA-trained operatives. Cured the same day.
Final inspection, handover dossier for the asbestos register, and the 25-year manufacturer-backed product warranty issued.
Finished encapsulation work photographed after completion — the same specification process and the same trained operatives we deploy in Nottingham.

The hardest part of any asbestos roof to seal. The finished layer follows every purlin and sheet lap continuously, with no gaps left at the structural junctions.

A full bay finished from apex to eaves. The corrugations are sealed but still legible, so the roof reads as encapsulated rather than replaced.

The roof-to-wall junction sealed as one continuous surface. This is where sheet edges are most exposed and where loose fibre most often originates.

No scaffolding programme, no licensed strip-out, no skips. The building keeps its roof, gains an insulated envelope, and the works go on the asbestos register as a documented management action.
Every photograph below is a finished installation, inspected and warranted — not a work in progress.

A complete bay sealed end to end. The uniform finish across the whole run is what distinguishes a specified job from a patch repair.

Encapsulation is a roof service. Here the roof sheets and purlins are sealed while the walls are deliberately left as found — scope kept exactly to specification.

The same building handed back. Nothing was stripped, nothing went to landfill, and the internal envelope is now sealed and insulated.
The honest comparison. Use it to shortlist — the free Nottingham survey confirms which route your roof actually needs.
| Factor | Encapsulation | Strip-and-recover |
|---|---|---|
| Typical installed cost | £15–£35 / m² installed | £55–£90 / m² stripped-and-recovered |
| Programme | Days | Weeks — scaffold, sheet, strip, re-roof |
| Waste stream | None | Licensed hazardous waste disposal |
| Building in use | Yes, throughout | Rarely — roof is open during works |
| Insulation gained | Yes, in the same pass | Only if a new insulated roof is specified |
| Right when | Sheets are sound but weathering or shedding fibre | Sheets are friable, badly damaged, or the building is being redeveloped |

Straight answers to the questions Nottingham estates and facilities managers ask us most.
Yes. Duratite covers all of Nottingham and the wider the East Midlands area for commercial asbestos roof encapsulation. Our manufacturer-trained Enverge applicators are mobilised across the region for free site surveys and Nexseal LE / Sucraseal underside spray foam encapsulation on commercial, industrial and agricultural buildings.
For most Nottingham postcodes we attend within 2-5 working days of enquiry. Urgent surveys can be arranged within 48-72 hours. Each visit includes a measured walk-over, photographic record, condition assessment and same-week written quote with no obligation.
For commercial work in Nottingham, Enverge Nexseal LE / Sucraseal underside spray foam encapsulation typically ranges from £15 to £35 per square metre supplied and installed at standard 25-50mm thickness. Final pricing depends on access, building size, substrate condition and ventilation requirements. Free site survey provides an exact figure with no obligation.
Yes. The Control of Asbestos Regulations 2012 explicitly recognises encapsulation (sealing in place) as a valid management option for asbestos-containing materials in good condition, and HSE guidance supports it. Sealing fibres in place with Enverge spray foam removes the disturbance risk that comes with stripping, while extending the useful life of the roof. We document the method and product so it can be recorded on your asbestos register.
Yes. After every encapsulation project we issue a written record (location, area treated, product, thickness, date, applicator) suitable for adding to the asbestos register held by the duty holder under CAR 2012. The encapsulated material is then formally identified as managed and sealed, not removed.
Removal is required if the asbestos cement sheets are friable, badly damaged, or if the roof is being demolished. Encapsulation is the right choice when the sheets are sound but releasing fibres at edges, fixings or weather-degraded surfaces — the spray foam locks fibres in, eliminates condensation drip and adds insulation in a single application. Removal typically costs £55-£90/m² stripped-and-recovered; encapsulation £15-£35/m². Free site survey to confirm.
Yes. We routinely schedule Nottingham commercial asbestos encapsulation for weekends, bank holidays and out-of-hours shifts so production and tenant operations are not interrupted. Enverge spray foam tack-frees within minutes and is fully cured the same day, which makes overnight installs reliable provided substrate temperature is within manufacturer limits.
Yes. All Nottingham encapsulation projects are carried out by Enverge-approved spray-foam applicators with manufacturer training, full public-liability insurance, working-at-height accreditation, CSCS-qualified operatives, and asbestos-awareness training under CAR 2012. The 25-year manufacturer-backed product warranty is only valid when installation is completed by approved applicators.
We regularly work across Castle Marina, Lenton, Beeston, Colwick — and every other commercial estate in and around Nottingham. If your building sits outside these areas we still cover all of the East Midlands; call 01208 832 602 to confirm your postcode.
Yes. The same approved contractor network that covers Nottingham works across the whole of the East Midlands, including Mansfield, Derby, Leicester. One survey team, one specification, one 25-year manufacturer-backed product warranty — wherever the building is.
Encapsulation is carried out by UKATA-trained operatives working to a written method statement, with full public liability insurance, CSCS-qualified staff and containment and monitoring protocols on site. The products are supplied by Duratite Building Products Limited, and the 25-year product warranty is manufacturer-backed on Enverge Nexseal LE — valid only when an approved applicator completes the install, which is exactly how every Duratite-managed project runs.
