Weather Defender closes the gap under your garage door for good. Keep out draughts, water, leaves and pests with a one-time fit that lasts for years.
The Challenge
The gap beneath a garage door is an open invitation — rainwater pools across the floor, cold draughts push through, and leaves and debris collect in the corners.
Weather Defender seals that threshold with solid-core PVC. It fits in under an hour and stays put, turning a recurring nuisance into a one-time fix.
Explore the Solution
Rainwater runs straight under the door, pooling on the floor and damaging anything stored at ground level.
An unsealed gap leaks heat all winter, making the garage cold and pushing up energy bills.
Leaves, dirt and grit blow in with every gust, leaving a mess that never seems to stay swept.
Simple Installation
Measure the full width of your garage door opening at floor level.
Choose the kit length that matches your opening and gap size.
Clean and dry the threshold so the adhesive bonds properly.
Apply the seal to the threshold and press firmly into place.

Seal out the weather today and forget about that gap for good.
Built for warehouses, depots and loading bays, Weather Defender stands up to constant traffic while keeping interiors dry, secure and weather-tight.
The Challenge
Industrial doors rarely sit flush. Wide thresholds let in driving rain, wind and pests across large floor areas where stock and equipment are exposed.
Weather Defender bridges uneven industrial floors with a rugged, vehicle-rated seal that holds up to forklifts and daily wear.
Explore the Solution
Large openings let surface water flow straight onto the warehouse floor, risking stock and creating slip hazards.
Unsealed bays bleed heat continuously, making large spaces expensive and uncomfortable to keep warm.
Gaps under shutters give rodents and birds easy access to stored goods and packaging.
Simple Installation
Measure each opening across its full width at floor level.
Choose heavy-duty kit lengths sized to your bay openings.
Sweep and clear the threshold so the seal sits flat.
Secure the seal to the floor and check the full length.

The Challenge
A workshop with an unsealed door fights a losing battle — moisture creeps in, dust drifts under the gap, and cold air makes long jobs miserable.
Weather Defender seals the threshold so the space stays dry and stable, protecting tools, materials and machinery year round.
Explore the Solution
Damp air under the door rusts tools and warps timber and materials over time.
Grit and leaves blow in constantly, settling on benches and into machinery.
A cold floor-level draught makes the workshop hard to heat and uncomfortable to use.
Simple Installation
Measure the width of your workshop door at floor level.
Pick the kit length that suits your door and gap.
Clear and clean the threshold ready for the seal.
Fit the seal and press it firmly along its length.
