FlueSnug 100mm – Solvent Weld Waste – Qty 1

The FlueSnug 100mm is the only all-in-one solution for sealing around boiler flues where pipework passes through an external or internal wall. It meets the airtightness requirements of Part L Building Regulations without needing sealant, perishable mortar or expensive air sealing tape. One product, one fit, job done.

Traditional methods of sealing around a flue involve a combination of mortar, frame sealant and sometimes specialist tape. The problem is that mortar cracks over time, sealant gets missed or applied badly, and air sealing tape is fiddly and costly. The FlueSnug 100mm replaces all of that with a single component that fits neatly around the pipe and closes the gap between the flue and the wall. It creates a permanent, airtight seal that will not shrink, crack or fall out on the first frosty morning.

Where the FlueSnug 100mm Gets Used

This version is specifically designed for solvent weld waste pipe applications. It fits a 152mm core-drilled hole, which is the standard size used when installing 100mm boiler flues through masonry or cavity walls. The product is approved by major boiler manufacturers, so there are no awkward conversations with building control or warranty departments.

Available in both black and white to suit different wall finishes, the FlueSnug sits flush against the wall surface and gives a clean, professional appearance from both inside and outside the property. Installers working to tight schedules will appreciate that there is no waiting for mortar to cure or sealant to skin over. Fix it, move on.

If you are working with smaller pipework, FlueSnug is also available for 32mm and 40mm waste pipe, and for 110mm soil pipe, so the same approach can be applied across multiple jobs on the same site.
