When installing in walls, the 2no. seals must be installed centrally with a 50mm air gap between the seals. Butt joints in adjacent seals must be offset by minimum 500mm. The pups do tend to wander a long way,” he says, recalling the rescue of a seal from outside a fish and chip shop this month, around the time another was spotted outside a nearby kebab shop on the Norfolk coast. During this reaction, the foam gradually compresses and is replaced by the expanding mass of intumescent graphite.

SideriseLGSLinear Gap Seals are made from an open-cell flame retardant acoustic foam laminate with a graphite intumescent coating containing binders which ensure material flexibility. To ensure fair pricing, we split colours into ‘Price Bands’ to group together similar priced colours. If you wish to search for the cheapest tinted colours, always select Price Band 1. Please keep a distance of more than 10 metres away from any seal. (that is the length of a large bus) To find Ready Mixed colours, search "ready mixed" or select the Ready Mixed 'colour chart'. To see Tinted colours select a colour chart such as RAL, BS, NCS, etc. or search for a colour/hue to see available or related options. When I first started, there were less than 100 pups born. It’s been rising steadily. There’s been more and more. When we got to 1,000, we thought, ‘bloody hell!’ … now we’re getting a bit blase,” he says.

When installing in gaps/joints in floors, top seal must be installed 100mm down from the top of the floor slab with an air gap of 50mm between the top and bottom seal. A pup was rescued after it was spotted wandering past an arcade and kebab shop in Hemsby, Norfolk, last week.

At the designed temperature, the intumescent coating begins to expand on the fire side of the joint.

Different products within the range have a different number of layers of materials, making them suitable for different size gaps and applications. The Intufoam system comprises of 1 metre lengths of a compressible foam core faced with a flexible intumescent material. Installation is by hand, the 1 metre lengths are simply compressed by hand and inserted in the linear gap where they will then expand holding themselves in place. Individual lengths should be installed with a tight butt joint, end to end. Where necessary to complete the length, Intufoam can be cut with a sharp knife or saw before inserting into the gap. Keep to the paths and roped-off viewing areas to keep you and the seals safe and to avoid unnecessary erosion on the dunes. Never get too close or walk between a cow and pup. Seals are likely to desert their pups if you disturb them, leaving them to starve to death.Colours are sold in the nearest tin size but actual paint volume per tin may vary up to 10% depending on colour Important points: Seal bites can lead to serious infection in both humans and dogs. If bitten, seek immediate medical or veterinarian treatment. Lara Howe, a marine officer with the Manx Wildlife Trust on the Isle of Man, says seals “ hauling out” in new places as their number grows is being widely celebrated by the public.
