LURCH double-wall insulation

LURCH is one of the leading manufacturers of high-quality insulated bottles and insulated containers made of stainless steel! Our products combine innovative technology, modern design and the highest quality to meet your requirements for thermal insulation and drinking pleasure. Our double-walled insulation is a key component that makes our products unique and special. Let's take a look together at how this technology works and what sets it apart.

Outstanding insulation

The key to sustained temperature control

The double-walled construction of our insulated bottles consists of two interlocking containers made of robust 18/8 stainless steel. A crucial element of this design is the vacuum-sealed space between these two containers, which plays a key role in thermal insulation. The vacuum minimises the exchange of heat between the contents of the bottle and the environment extremely effectively. This targeted blocking of heat transfer through convection* or conduction** enables us to achieve impressive temperature resistance.

Another remarkable feature of our insulated bottles and insulated containers is the copper-coated exterior of the inner stainless steel container. This special finishing process helps to further reduce heat transfer in combination with the vacuum.

In addition, our bottle lids are designed to effectively prevent a thermal bridge at the thread. The coloured silicone ring on the lid not only provides an appealing look, but also offers sufficient grip even with wet hands and makes it easier to open your insulated bottle effortlessly.

Food-safe and flavour-neutral

Unadulterated enjoyment

The use of high-quality 18/8 stainless steel not only ensures a robust and durable construction, but also a food-safe and flavour-neutral environment for your drinks. So you can enjoy every sip without any unpleasant flavours or odours that could be given off by inferior materials.

100% leak-proof closure

even for carbonated drinks

Our insulated bottles are not only suitable for everyday use, but also for fizzy drinks such as carbonated soft drinks or refreshing mineral water. The 100% tight seal ensures that not a drop is lost and your drink stays as fresh and sparkling as you like it.

But, here's a bit of a buzzkill: Don't shake like crazy! Because even though our bottles are heroically tight, excessive shaking could lead to internal pressure, which will be noticeably released when the bottle is opened.

Long-lasting temperature control

Hot or cold, just as you like it

Whether you want to enjoy your coffee hot in the morning or prefer an ice-cold refreshing drink on a sunny day, our insulated bottles keep the temperature hot for up to 12 hours or cold for up to 24 hours. No matter where your day takes you, you can rely on a perfect drinking temperature.

*Convection is the transfer of heat through the movement of gases or liquids, where heated material rises and is replaced by cooler flows, creating circulation.

**Conduction describes the direct transfer of heat energy through the collision of particles in a solid material when an area of it is heated and the heat spreads through direct contact.
