Everbuild Sika high-temperature sealants for boiler and furnace joints

High-temperature silicone sealants from Everbuild Sika are formulated to seal joints around boilers, flue pipes and heat-exposed connections. They cure to a flexible, heat- and weather-resistant film that maintains integrity during thermal cycling and exposure to combustion by-products. Some versions are designed for use on metal, ceramic and brick substrates, and can seal joint gaps where movement occurs due to expansion and contraction.

Intumescent and fire-rated sealing solutions

Intumescent products in the Everbuild Sika furnace line expand when exposed to heat, helping to seal duct penetrations and protect surrounding materials. These solutions are used where fire resistance and barrier integrity are required by regulation, such as around flue penetrations in walls and ceilings or in locations where fire-rated seals are mandated. Some models combine intumescence with adhesive strength for fixing panels or sleeves.

How to compare Everbuild Sika furnace and boiler accessories

When comparing products in this category, pay attention to temperature ratings and cure times, as well as surface compatibility and application method. Look for formulations appropriate for metal, brick or plaster substrates, and for use with flue gas environments. Consider packaging and dispensing options (caulk cartridges, sealant tubes) and check whether a product is labeled as fire-rated or intumescent. Some versions are designed for rapid curing, while others emphasize flexibility to absorb movement. Finally, verify any relevant approvals or certifications that relate to UK building regulations and boiler installation standards.
