Our focus is on providing stylish and functional drinkware as well as informing our customers about the advanced technology that makes them. Our commitment to technology goes beyond the innovative double-walled insulation that ensures superior temperature retention.

We are dedicated to providing you with drinkware that not only meets your needs but also exceeds your expectations in terms of performance and reliability.

Technologies used in our drinkware

Our drinkware undergoes advanced technology integration at Just Days to ensure exceptional performance and durability.

Insulation – Insulation technology in water bottles focuses on minimising heat transfer between the beverage inside the bottle and the external environment.

Double wall insulation – Insulated water bottles are often constructed with two walls. This means there are two layers of material, with a gap between insulating materials like foam.
Also, our drinkware is designed with ceramic-lined, insulated inner walls for taste purity. And a stainless steel exterior for durability and sleek design, making it perfect for both everyday use.

Vacuum insulation – A vacuum-sealed space between the inner walls is a common feature of many high-quality bottles. This vacuum significantly decreases heat transfer through convection and conduction.
The bottles or tumblers can effectively maintain the temperature of the liquid inside because there are no molecules to conduct heat.

Insulating materials – Insulating materials like foam or copper linings can be used in bottles in addition to vacuum insulation. To further reduce heat transfer, foam can be inserted between the walls, while copper linings have excellent thermal conductivity, which helps to enhance insulation properties.
Temperature retention – These bottles can hold beverages hot or cold for extended periods due to the combination of double wall construction and insulation materials. They are designed to maintain the temperature of the liquid inside for several hours.
Durability and portability – stainless steel is the common material for the outer layer and ceramic is for the inner layer, due to their durability, resistance to corrosion and light wellness. This is why our double walled insulated bottles and tumblers are ideal for outdoor activities and travel.

Ceramic inner wall

The ceramic inner wall of our double wall insulated drinkware offers multiple essential benefits. The smooth, non-metallic surface inside the bottle improves taste purity by preventing any metallic taste or odour from affecting your beverages. This feature makes our drinkware particularly suitable for those who prefer a clean and natural taste experience.

Additionally, ceramic is known for its thermal stability, helping to maintain the temperature of your drinks without affecting their flavour. It also adds a layer of insulation, complementing the double wall design to keep your beverages hot or cold for extended periods.

Our ceramic-lined bottles and tumblers combine functionality with aesthetic appeal, providing a stylish and eco-friendly option for everyday hydration needs. It’s durable, easy to clean and ensures that every sip you take is refreshingly free from any unwanted flavours.

Stainless steel outside layer – This layer in our double wall insulated drinkware serves multiple important functions.

Durability – The strength and corrosion resistance of stainless steel make it an ideal choice for outdoor use and daily commutes. Our drinkware is protected from impacts and maintains its structural integrity over time.
Insulation support – By adding an additional insulation layer, the stainless steel exterior complements the inner ceramic wall or vacuum- sealed space. The dual layer construction helps to minimise heat transfer, keeping beverages hot and cold for longer periods of time.
Hygiene and safety – Stainless steel is a hygienic material that is easy to clean and does not retain flavours from previous beverages. It is also naturally BPA-free and does not leach harmful chemicals into your drinks, ensuring safe and healthy hydration.
Aesthetic appeal – Our drinkware looks sleek and modern because of this stainless steel exterior’s functional benefits. You can choose a style that suits your personal taste and lifestyle due to its availability in different finishes and colours.

Double wall insulation technology

This is a method used in drinkware to enhance thermal retention and protect the temperature of beverages. This insulation involves the creation of two layers of material, typically stainless steel, that are carefully constructed to create a barrier against heat transfer. The layers are separated by a vacuum-sealed space or an insulating material like foam. The temperature of the beverage inside stays stable due to the strategic design’s effective minimisation of heat transfer through conduction and convection.

How is double wall insulation technology used in our products?

Enhance thermal retention – Our products maintain the period by using double wall insulation. Also our drinkware can keep your drink at the perfect temperature. Whether it’s hot coffee in the morning or cold water throughout the day.
Durability and reliability – the stainless steel construction provides insulation, durability and resistance to impacts. So our drinkware is suitable for a variety of environments.
Versatility in use – Our insulated bottles and tumblers can be taken with you anywhere you go due to their versatility. We offer products that maintain beverage temperatures consistently and reliably. Whether it’s at the office or during workouts.
User experience – Our priority is to improve the user experience by combining advanced insulation technology with thoughtful design elements. For comfortable handling, these features include simple shapes, leak proof lids and stylish finishes that appeal to personal preferences.
Environmental benefits – these bottles and tumblers are typically designed for long term use. So our desire is to encourage consumers to choose reusable options over single use plastic bottles. This reduces the amount of plastic waste and environmental pollution

How does double wall insulation work?

Double wall insulation in bottles and tumblers creates a barrier between two layers of material, stainless steel, with a vacuum or air gap in between designs. This design prevents heat transfer through conduction, convection and radiation, keeping hot or cold beverages at the same temperature for a long period of time. By stopping heat from leaving or entering the drink, staying hot or cold for longer reduces condensation and increases durability.

Preservation of temperature
- Hot beverages; When hot beverages are poured into a double wall insulated bottle or tumbler, the heat is kept in the inner layer. The insulation prevents heat from leaving the cooler outer layer or the environment. Then keep the beverage hot for a long time.
- Cold beverages; In the same way, when cold beverages are stored in a double wall insulated bottle, the insulation helps prevent heat from the surroundings from warming up the beverages. This keeps the beverage cold and refreshing for a long time.

Benefits of double wall insulated drinkware

Temperature retention – The main advantage is that it can maintain the temperature of both hot and cold beverages. The construction of two walls results in a vacuum or air gap between them, which reduces heat transfer. This is mostly preferred by someone who wants both hot and cold drinks for a longer time.
No sweating – Double wall insulated drinkware is better than single walled cups because it prevents condensation from forming when cold drinks are held. it keeps your hands and surfaces dry.
Durability – The dual layers add durability and strength to the drinkware, making it less likely to break or dent compared to single wall options. It is suitable for both indoor and outdoor use because it can resist accidental falls and impacts better.
Versatility – A wide range of beverages can be served with double wall insulated drinkware, which can be used for tea, coffee, water, juice etc. They are also available in various sizes and shapes to suit different preferences and needs.
Safety – The use of stainless steel, which is BPA free and safe for beverages, is common in many double wall insulated drinkware products. Also stainless steel is resistant to rust and corrosion, which means the drinkware will last longer.
Environmentally friendly – By using reusable insulated drinkware, the use of disposable cups and bottles is reduced, which helps conserve the environment by minimising waste.

Safety of double wall insulation

Double wall insulated drinkware prioritises safety through its design and material. As you know, our products are made from high-quality stainless steel and free from harmful chemicals such as BPA, making them safe for storing both hot and cold beverages.
