In response to concerns over the use of torch-applied roofing in high-risk areas, Langley Waterproofing Systems Ltd, the national roofing and waterproofing expert, has introduced its new Supracoating RLV cold-applied liquid detailing system.
Consisting of a bitumen polyurethane liquid, Supracoating RLV removes the risk of fire that is sometimes associated with carrying out detailing work, while providing excellent waterproofing properties.
Due to its flexibility and ease of application, the system can be used around complex areas, such as irregular shaped roof penetrations, and can be supported by matting where reinforcement is required. Supracoating RLV can also be used to carry out small-scale repairs, and compatible mastics are available to fill joints and gaps with ease.
Adhering to any clean, dry, contaminant-free substrate, the system seeps through the top layer of porous mineral and slate finishes of felt membrane roof coverings connecting to the bitumen beneath giving far greater adhesion and integrity. This is in contrast to the adhesion found in some plastic-based liquid systems which have a tendency to sit on top of mineral-finished capping materials creating a situation where water can travel beneath the product by capillary action.
Supracoating RLV can also be broadcast with the same granules used on any surrounding mineral cap sheet, offering a complimentary appearance and equal UV resistance.
Steve Rowe, Product Development Manager at Langley Waterproofing said: “Fire is, understandably, a major concern for building owners and insurers alike.
“While details such as upstands and abutments can be rebuilt, this is often a costly and time-consuming procedure, leading many to consider refurbishment. In recognition of this requirement, and fears over the use of hot-applied systems, we’ve developed Supracoating RLV, which offers superior performance while removing the risk of fire.”
