Your Attic Floor Is Insulated. Your Attic Door Isn't.
Most homes have a thick blanket of insulation across the attic floor — except for one spot. The pull-down ladder door is often just a thin panel of plywood with gaps around the frame. That's 8 to 10 square feet where the air you pay to heat and cool slips away, day and night.
LELUMP™ zips over that opening and wraps it in three layers of reflective insulation. Your warm air stays downstairs in winter. Attic heat stays up there in summer.
- Warmer winters — blocks the gap where rising heat escapes into the attic
- Cooler summers — reflects attic heat away from the rooms below
- Less wasted energy — your heating and cooling don't have to work as hard
Works Like a Thermos for Your Attic Door
Three layers. Each one has a job.
A thermos keeps drinks hot or cold by pairing a reflective lining with an insulating barrier. LELUMP™ uses the same idea to keep heat on the side where it belongs.
- Reflective aluminum foil — Bounces back up to 97% of radiant heat, the kind that pours off a sun-baked roof.
- Air-bubble core — Sealed pockets of still air slow heat as it tries to pass through.
- Second foil layer — Adds another reflective barrier and extra strength.
Built for Every Trip Into the Attic
The zipper is the part you'll use most — so that's where we started.
- Dual-pull smooth zipper — Opens and closes from either end, even when you're reaching overhead from the ladder.
- High-reflectivity aluminum foil — Tough, tear-resistant and easy to wipe clean.
- Reinforced stitched edges — Heavy-duty binding along every seam helps the cover hold its shape, season after season.
- Fire-retardant, water-resistant materials — Extra peace of mind for a space you rarely check.
No Contractor. No Mess. Done in Minutes.
