Gap seals for gates & doors – the big comparison
Effectively block drafts, rodents, and rain: Gap seals for garage doors, sectional doors, doors, and loading ramps. Magnetic, adjustable, with stainless steel mesh.
Why gap sealing?
Gaps under gates and doors are more than just visually unsightly – they lead to:
- Heat loss & high heating costs due to draughts
- Moisture & mold in the rain
- Infestation by mice, rats and insects
- Waste of energy in the garage, basement or hall
Typical problems without sealing
- “ Garage door leaking at the bottom – what to do? ”
- “ Door gap sealing winter ”
- “ Sealing against mice in the basement ”
- “ Sealing the gap under a sectional door ”
