Thermoslide 80 Aluminium Sliding Doors by Azure Outdoor Living
Energy-Efficient Sliding Patio Doors
The Thermoslide 80 provides a modern and super-efficient sliding door system, designed to maximise natural light and living space. Its cleverly engineered thermally broken and insulated aluminium frames allow you to create larger openings with glass panels that can be easily moved across the widest of elevations. This revolutionary sliding door system also offers market-leading thermal performance, allowing you to make the most of natural sunlight while keeping your home comfortable year-round.
Aluminium Patio Doors with advanced engineering
The Thermoslide 80 system is a revolutionary design that sets the standard for both heat retention and thermal efficiency. The unique extendable pressure seal, concealed within the door panel, top and bottom, helps to trap heat inside when in a closed position. By turning the handle this seal extends tight against the tracks and prevents heat from escaping. This makes it ideal for use in even extreme external environments where heat loss is prone to occur. This innovative system can guarantee thermal efficiency and keep interior temperatures stable all year round.

Thermoslide 80 Aluminium Sliding Doors Key features and benefits
Large Thermal Breaks
Sliding patio doors are great for inviting natural light and keeping the elements out of a space but the metal can conduct cold and heat, if not adequately insulated. To provide effective insulation against this heat transfer, doors need a thermal barrier. This is an area of air or insulating material that acts as a barrier between the inside and outside faces of the door. The thicker and more substantial the thermal break, the better it will work to keep temperatures regulated on either side of an aluminium door. In this way, having a thicker thermal barrier can drastically improve energy efficiency by preventing heat energy from transferring between these two different sides. Not only does this help reduce waste in terms of cost savings from using less energy, but it also helps reduce environmental impacts from burning too much fuel. Thermoslide 80 sliding glass doors come with an impressive feature that many other systems cannot offer: Extremely Large Thermal Breaks. This design element is essential for good insulation. The unique large thermal breaks of these doors significantly raise the thermal resistance, providing exceptional insulation in your home or office. Installing Thermoslide 80 Aluminium Sliding Doors offers a great way to battle cold temperatures and reduce energy bills year-round.
Thermally Insulated Profiles
The Thermoslide 80 sliding patio doors have a highly effective way to keep your interior insulated. By using insulation inside the aluminium profiles, the users of Thermoslide 80 sliding patio doors can take advantage of enhanced energy efficiency, unbeatable thermal protection and quality sound insulation. The foam which is used to fill the gaps between the glass chambers and frames creates an additional buffer zone – this ensures any existing cold draughts or hot winds will not penetrate into your interior. This results in a more consistent temperature throughout the year, meaning you will save money on climate control appliances such as air-conditioners or heaters. With insulated profiles, your home can enjoy an enveloping feeling of warmth during chilly months while also safeguarding against extreme temperatures in the summertime.
Extendable Gaket seals
The Thermoslide 80 door is designed with extendable seals on each door to provide an elevated level of thermal separation and protect your building from the elements. The extended seals give users maximum weatherproofing and air permeability, guaranteeing a comfortable temperature indoors regardless of the environment outside. Easily operated via the handle, these sophisticated seals give users unparalleled control over their level of entry and weather protection. This is a reassuring feature for those living in locations especially prone to extreme climates, letting them know that their property is secure against unexpected inclement weather.

Thermoslide 80 Aluminium Features
Qualicoat Marine grade paint finish as standard
Our sliding doors are crafted with a premium look and feel that is designed to be long-lasting. This quality standard is achieved by powder coating them to a Marine grade finish that adheres to the Qualicoat Seaside Class standard. This process involves a detailed etching of the sliding doors before they undergo painting, which ensures that surface contaminants are removed and ultimate protection is provided. As part of our guarantee, the sliding door frames are backed by a 10-year warranty so that our customers can experience enjoyment for years to come without paint degradation.
Exterior aluminium doors in harsh sea air environments require a specialized coat of paint to ensure their long-term stability and durability. That’s why Qualicoat seaside marine grade paint finish is such a great choice – it keeps salt air from finding its way beneath the powder-coated finish, preventing any potential deterioration. The rigidity and robustness of Qualicoat seaside makes it perfect for protecting your external doors from extreme weathering, corrosion, and chalking caused by sea air. With this advanced technology, you can be confident that your external sliding doors will keep looking as good as new for years to come – making Qualicoat seaside a wise decision to safeguard your investment in an external door solution.

Thermoslide 80 Aluminium Sliding Patio Doors Overview
Why Choose Sliding Patio Doors over other doors?
Sliding patio doors are becoming a great rival to the more traditional french doors and even modern bifold door systems. Large patio doors create an inviting entrance into your home with large expanses of glass allowing easy access and a seamless transition from indoors to out. With a low threshold bottom track, they can be integrated perfectly into any home improvement project. They come fitted with a multi-point locking mechanism making them secure, yet offer individual panels that can be opened up for reduced air conditioning bills in the summer months. Unlike bifold doors, large sliding glass doors provide beautiful views and aesthetics when closed that other entries like UPVC patio doors or french patio doors cannot replicate- making it a great choice for any homeowner looking for an upgrade or update to their living space.
