Asbestos, a naturally occurring mineral, has been used extensively in some 500,000 buildings in the UK over the last decades. Where removal is required, Armstrong York has the infrastructure and expertise to accommodate both small and large multi-million pound projects as one of the largest independent consultants in the UK.

Sprayed Asbestos Coatings
Sprayed Asbestos, commonly known as Limpet or Flock Insulation, was used extensively throughout the 1960's and early 1970's. The material was used mainly for its fire retardant, acoustic and anti-condensation properties. Sprayed Asbestos usually contains up to 85% Asbestos fibre.
Sprayed Asbestos coatings can be extremely vulnerable to impact damage. water penetration, and will deteriorate with age.
The potential for fibre release from the insulation is high and contamination resulting from damage, uncontrolled removal and migratory Asbestos fibre is a considerable risk.
Typical applications include:
- Steel / Concrete Beams
- Ceilings
- Walls
- Roofs (internal)
- Soffits
-
Asbestos Insulation Board (AIB)
Asbestos Insulation Board, commonly known as Asbestolux in the construction industry, was used throughout the UK from the 1950's right through to the early 1980's
The material was widely used as standard fire protection, heat and acoustic insulation and as a general building board.
Typically AIB's contain between 25% and 40% Asbestos fibre, normally Brown Asbestos (Amosite) and / or White Asbestos (Chrysotile). The board can be vulnerable to impact damage, and will deteriorate with age.
The potential for fibre release from the board in its raw form is high and contamination resulting from damage, uncontrolled removal and migratory Asbestos fibre is a considerable risk.
Typical applications include:
- Doors (internal / external)
- Partition Walling
- Riser Panels
- Ceilings
- Fire Breaks
-
Asbestos Lagging
Asbestos lagging, commonly known as Hardset or Sectional Insulation, was used extensively in the building industry from the 1920 right through to the mid 1970's.
The material was typically used for thermal insulation. Blue Asbestos (Crocidolite) was extensively used within boiler houses and other similar environments due to its noted acid resistant properties.
The lagging can contain up to 100% Asbestos fibre. Asbestos lagging can be vulnerable to impact damage, vibration, water penetration, and will deteriorate with age.
The potential for fibre release from the lagging is high and contamination resulting from damage, uncontrolled removal and migratory Asbestos fibre is a considerable risk.
Typical applications include:
- Pipes
- Lofts
- Vessels
- Rising Ducts
- Boilers
- Floor Voids
-
Asbestos Cement
Asbestos cement products were in widespread use throughout the building industry from the 1940's right up until the mid 1990's.
Asbestos cement products had many uses, and often came in preformed applications such as water pipes, flue sections, corrugated roof sheets and flat boards.
Regulations came into force in November 1999 banning the use and supply of Asbestos cement (Chrysotile) products. Care should be given to these products, as more often than not they tend to be found in their raw, untreated state.
The potential for fibre release is fairly low, however issues of contamination can arise when Asbestos cement is damaged or removed without suitable control.
Typical applications include:
- Ceilings
- Wall Partitioning
- Roof Sheets (Corrugated)
- Water Tanks
- Flue Pipes
- Tiles
