DAFA Renovation Collars – Retrofit Pipe & Cable Sealing Grommets
Description
Introducing DAFA Renovation Collars, the premium range of airtight retrofit pipe and cable sealing grommets designed to optimise energy efficiency in your home or commercial property. Specifically crafted to securely seal around existing pipes and cables that penetrate the airtightness layer, these innovative grommets provide a reliable and durable airtight seal, minimising heat loss and preventing unwanted draughts..
When pipes or cables penetrate your property's airtightness layer, it's crucial they are securely sealed to maintain insulation performance. DAFA Renovation Collars are made from non-ageing, elastic polyisobutylene, a flexible material that allows for a tight fit and secure feed-through for cables and pipes. The high elasticity of our seals offers excellent protection against piercing and ensures long-lasting durability, effectively eliminating gaps around retrofit installations.
