Cavity wall insulation system

Platinum Fulfil

Efficient, effective cavity wall insulation that fulfils all your thermal requirements Springvale Fulfil is a tightly interlocking cavity insulation panel individually moulded from lightweight closed cell EPS to provide a fast, efficient and cost-effective solution to insulating new masonry walls.

It is available in original white EPS or as Platinum, to provide even higher insulation values. Platinum Fulfil is an EPS board which incorporates a graphite component called Neopor®, manufactured by BASF to provide significantly improved thermal insulation performance, for example, to achieve higher levels of the Code for Sustainable Homes or just to improve SAP ratings.

Springvale Fulfil products are suitable for use in new buildings up to and including 12 metres in height. Fulfil boards are effective in achieving the required U-value of new external cavity walls with masonry inner and outer leaves.

The Springvale Fulfil concept was developed in conjunction with the Building Research Establishment and in consultation with NHBC. Fulfil boards are tongued and grooved on all four edges to provide tightly interlocking joints which prevent cold bridging and water penetration. On the external face, along the bottom edge of the board, a bellcast feature overlaps the top of the next board and protects the lateral joints by shedding water past the joint. A series of 5 or 10mm water 'run-off' angle fillets on the external face of the panel direct any water which has penetrated the external leaf of the wall down the face of the fulfil panels and back onto the outer masonry leaf.

With their moulded skin, Springvale Fulfil and Platinum Fulfil are highly water resistant and encourage rapid water run-off.

The environmental integrity of Springvale Fulfil products is exceptional:

  • Zero ODP (Ozone Depletion Potential)
  • Zero GWP (Global Warming Potential)
  • BRE Ecopoints rating of 0.043
  • CFC, HFC and HCFC free
  • No wastage on site
  • Boards are 100% recyclable
  • Contains recycled content

Environmental Integrity

Springvale Fulfil and Platinum Fulfil are dimensionally stable products which are resistant to attack from bacteria, moulds and fungi and will not provide nutrient value for insects or vermin. They are non-toxic and non-irritant. With the exception of its enhanced thermal insulation efficiency the physical and ecological properties of Neopor® material from BASF are comparable to those of conventional EPS.


Fulfil and Platinum Fulfil have been awarded BBA certificate No 95/3160. The products are manufactured to the requirements of BS EN 13163:2001 and under an ISO 9001:2000 approved quality management system.

Weather resistance

Springvale Fulfil and Platinum Fulfil are designed for use in any exposure zone in buildings up to 12m in height. However in severe exposure zones, where the use of an external render coat would be normal practice the use of Springvale Fulfil or Platinum Fulfil does not preclude this requirement.

All corners should be protected with a vertical DPC, extending at least 150mm on each face between the board's external leaf. At internal corners, remove flutes where boards lap. As with all cavity wall insulation the construction detailing should, where appropriate, comply with good practice as described in the BBA joint publication 'Cavity Insulation of Masonry Walls – Dampness Risks and How to Minimise Them'.

2. The 5mm thick tapered flutes are not included within the board thickness, hence the cavity width design sizes are 75mm and 100mm

Wall Ties

Wall ties for use with Springvale Fulfil and Platinum Fulfil cavity boards should be BBA approved and meet the requirements of DD140.

Behaviour in relation to fire

The Reaction to Fire Classification of Springvale Fulfil products as supplied on the market is Euroclass E. However, the classification of construction works incorporating Fulfil and Platinum Fulfil boards (end use application) will be considerably better. When used in a masonry cavity wall a Euroclass B classification can be expected.


Springvale Fulfil and Platinum Fulfil boards must not be used in direct contact with PVC sheathed electrical cables or hot water pipes. Electrical cables should be enclosed in suitable conduit.
