Cold Weather Gap Sealing with LENTEK™ Fireblock and LENTEK™ Insulating Foam Sealants
As temperatures drop, small openings around penetrations, framing, and fixtures can quickly lead to drafts, heat loss, and moisture concerns. LENTEK™ Fireblock Foam Sealant and LENTEK™ Insulating Foam Sealant are designed to help professionals address cold-weather air leakage with dependable results. Each product serves a specific purpose while supporting efficient, professional installation.
Why Winter Gap Sealing Matters
During cold months, the expansion and contraction of building materials can create or widen gaps. These openings allow cold air infiltration, reduce indoor comfort, and increase heating demand. Unsealed penetrations can also introduce moisture, which may lead to condensation or long-term damage.
Sealing gaps before and during winter helps:
- Reduce drafts and temperature fluctuations
- Improve heating system efficiency
- Protect interior spaces from cold air and moisture
- Support consistent building performance throughout the season
LENTEK™ Insulating Foam Sealant for Thermal Control
LENTEK™ Insulating Foam Sealant is designed to seal gaps that contribute directly to heat loss. It expands to fill voids and helps limit air movement through walls, floors, and ceilings.
APPLICATIONS:
- Sealing window and door frames
- Filling gaps around wall and ceiling penetrations
- Insulating around plumbing and electrical openings
- Closing cracks that allow cold air infiltration
By reducing uncontrolled air movement, LENTEK™ Insulating Foam Sealant supports energy efficiency and indoor comfort during winter conditions.
LENTEK™ Fireblock Foam Sealant for Penetrations
LENTEK™ Fireblock Foam Sealant is formulated for sealing penetrations where fireblocking is required. In colder months, these areas are often key sources of air leakage if left unsealed.
APPLICATIONS:
- Sealing pipe, conduit, and cable penetrations
- Filling gaps between framing members
- Closing openings in top plates, bottom plates, and utility chases
- Filling gaps in wood framing around chimneys or fireplaces to reduce heat loss
In addition to helping limit air movement, LENTEK™ Fireblock Foam Sealant supports code-driven fireblocking requirements commonly encountered in residential and light commercial construction.
