Weatherproof Your Windows Before Winter
Seal drafty window frames before cold weather hits. Aluminium butyl tape blocks moisture and reduces heat loss.
Why windows leak in winter
Cold air isn't the only problem — moisture drives rot in wooden frames and mould in wall cavities. Failed exterior seals let rain in behind the frame.
Where to apply tape
- Exterior frame-to-wall joints
- Glazing bead gaps (temporary fix)
- Metal flashing overlaps
Preparation tips
Clean the surface with a dry cloth. Remove loose paint or old cracked sealant. Apply 50mm strips with overlap at corners.
Energy savings
Even a small gap lets warm air escape. Sealing before the first frost takes less than an hour and costs far less than a window replacement.
Recommended pack
The Home Seal 4-roll pack (€34.99) covers multiple windows with spare tape for gutters or roof seams.
