If you wish to use your terrace or balcony even in the colder months, you face the question of which decorative elements and accessories can remain outdoors permanently. Not every material tolerates frost, moisture, and temperature fluctuations equally well. While some pieces can overwinter without damage, others require a sheltered spot or must be brought indoors. The right choice saves work and preserves your investment. Below, you will learn which materials are suitable for winter and what to consider when placing them.
Materials that withstand frost and moisture
Aluminum, stainless steel, and galvanized steel are among the most resistant materials for outdoor use. They do not rust, tolerate sub-zero temperatures, and can be easily wiped clean if necessary. Lanterns, wind lights, and planters made from these metals can remain outdoors all year round. Powder-coated surfaces offer additional protection and retain their color even after several winters.
Natural stone such as granite or basalt is also frost-resistant, provided it is dense enough and absorbs little water. Porous stones can crack in frost if absorbed water expands. Ceramics and stoneware are only winter-proof if they have been fired at a high temperature and have a closed surface. Terracotta, however, should be brought indoors, as it retains water and cracks in frost.
High-quality plastics and synthetic resins usually survive the winter without problems. They become brittle if they are UV-stabilized and designed for outdoor use. Cheap plastics lose their elasticity and break in the cold.
Textiles and upholstery: what stays, what goes
Outdoor fabrics made of polyester or acrylic with a water-repellent coating can withstand moisture for a short time but should not be left in the rain for months. Cushions and pads belong in a dry room or a waterproof box. Even textiles declared as weather-resistant suffer from continuous moisture, mold, and UV radiation in winter.
Outdoor rugs made of polypropylene withstand moisture better than natural fibers. Nevertheless, it is advisable to roll them up before the first frost and store them dry. Standing water and ice damage the backing and lead to discoloration.
Proper treatment of wood and natural materials
Teak, robinia, and oak are naturally resistant and can overwinter outdoors. Over time, they develop a silvery-gray patina that protects the wood. If you want to preserve the original color, treat the surface with a suitable oil in autumn. Other woods such as pine or spruce require a glaze or varnish to repel moisture.
Woven pieces made of rattan or willow are unsuitable for winter. The fibers swell when wet and become brittle. Polyrattan, a synthetic weave, tolerates frost and rain much better but should also be placed in a sheltered spot to extend its lifespan.
Glass, ceramics, and porcelain outdoors
Glass wind lights and vases can remain outdoors, provided no water freezes inside. Standing water expands when freezing and can cause the glass to crack. Empty or covered vessels survive the cold without damage. Thick-walled glass is more robust than thin-walled.
Porcelain and stoneware with a dense glaze are frost-resistant. Unglazed ceramics absorb moisture and can crack in sub-zero temperatures. Pay attention to the manufacturer's information on frost resistance before leaving planters or bowls outdoors permanently.
Location and protection: where accessories are better placed
Even winter-proof materials benefit from a sheltered spot. Under a canopy, against a house wall, or in a niche, accessories are protected from direct rain and snow. Waterlogging is more damaging than occasional moisture that can dry out again.
Place vessels on feet or saucers so that water can drain off. Ground moisture and frost from below attack materials more severely than precipitation from above. A slight incline prevents water from collecting in depressions.
| Material | Frost Resistance | Recommendation |
|---|---|---|
| Aluminum, Stainless Steel | Very High | Can remain outdoors |
| Teak, Robinia | High | Oiling extends lifespan |
| Polyrattan | Medium to High | Place under cover |
| Outdoor Textiles | Low | Store dry |
| Terracotta | Low | Bring indoors |
| Glass (empty) | High | No standing water |
Care before and after winter
Clean all accessories thoroughly before leaving them outdoors or storing them. Dirt and organic residues promote mold and discoloration. You can wipe metal with a damp cloth and clean wood with a soft brush.
After winter, a renewed cleaning and inspection for damage are recommended. Small rust spots on metal can be sanded down and repainted before they spread. Wood can be re-oiled to seal the surface.
- Empty all vessels so no water can freeze
- Cover sensitive pieces with breathable protective covers
- Regularly check drains and drainage
- Store textiles and upholstery in dry rooms
- Treat wood with oil or glaze before the first frost

Frequently Asked Questions
Can metal lanterns stay outdoors all year round?
Lanterns made of aluminum, stainless steel, or galvanized steel are suitable for year-round outdoor use. Ensure that no candle residues or water can freeze inside. Powder-coated surfaces offer additional protection against corrosion and retain their color even in frost and humidity.
How do I know if ceramics are frost-proof?
Frost-proof ceramics are fired at a minimum of 1200 degrees Celsius and have a dense, closed surface. The manufacturer usually indicates this on the label or in the product description. Unglazed or low-fired ceramics absorb water, which expands when freezing and can crack the material. If in doubt, you should bring the piece indoors.
Do I need to store outdoor rugs in winter?
Outdoor rugs made of polypropylene tolerate moisture better than natural fibers but should be protected from prolonged frost and snow. Standing water and ice can damage the backing and lead to discoloration. Roll up the rug before the first frost and store it dry to extend its lifespan.
How do I protect wooden furniture from winter weather damage?
Treat wood in autumn with a suitable oil or glaze to seal the surface. Teak and robinia are naturally resistant and can remain untreated but will develop a gray patina. If possible, place furniture under a canopy or against a sheltered house wall. Avoid waterlogging by ensuring good drainage.
