Cold-processed pure wax foundation - 424x162 - Langstroth 3/4

Cold Pressed Wax Foundation Langstroth (424 × 162 mm) – 1 kg

Give your bee colony a reliable foundation for building new comb. Our premium foundation sheets for Langstroth frame size measuring 424 × 162 mm are especially suitable for shallow supers (Langstroth 2/3, 159). We manufacture them from 100% beeswax from Czech beekeepers and thanks to cold pressing (rolling) technology they are flexible, strong and significantly less prone to cracking than conventional cast foundation sheets – which you'll especially appreciate when working in colder weather.

Why choose our rolled foundation sheets

Healthy comb is the foundation of healthy beekeeping, which is why we emphasize cleanliness and production control. We sterilize the wax at 117 °C for 1 hour, which minimizes the risk of transmitting pathogenic germs including American foulbrood spores. During cleaning we don't use any chemicals or acids – we treat the wax only physically (sedimentation and filtration).

Main advantages for beekeepers:

• Verified wax purity: We regularly test foundation sheets in VŠCHT laboratories (FTIR analysis) for the presence of paraffin. You're placing a genuine bee product into the hive.
• Trouble-free work: Rolled foundation sheets break less, embed well and handling them is quick and convenient.
• Consistent dimensions and uniformity: Production on modern lines ensures identical execution piece by piece. In 1 kg packaging there are approximately 16 pieces (± 5 %).

Recommendations for proper insertion into frames

When wiring and embedding we recommend positioning the foundation sheet against the top bar. Bees naturally build downward and will easily fill any gap at the bottom bar. This also maintains equal side gaps on both sides (approximately 1–2 mm), which allows bee passage and helps prevent comb deformation due to thermal expansion in the hive.

What is wax bloom (patina)

During longer storage or in cooler environments, a fine light coating may appear on the surface of foundation sheets – called wax bloom (patina). This is not a defect, but often a typical sign of genuine beeswax. It has no effect on quality or function. If desired, it can be easily removed by brief heating (e.g. with a hair dryer) or brief exposure to sunlight; but bees will handle it without any problem.
