MasterPatio Aluminium Sliding Doors: Redefining Thermal Superiority

When sliding patio doors started to become fashionable, around 40 years ago, there wasn’t a huge amount of choice on offer for the UK homeowner who fancied replacing their old fashioned single glazed windows.

These doors were heavy, closing with a ‘clunk!’ that shook the entire house. They were dark too, almost invariably blocking out natural light, especially in winter. And there was no choice over style – it was thick white uPVC or nothing.

Thanks to advances in technology, those days are long gone. Today’s aluminium patio doors are engineered with imagination, efficiency and high performance in mind. Ultra-thin sightlines have replaced clunky thick plastic and the glass panels now shut with a satisfying ‘shhh’. Such doors really possess the wow factor and have become a must-have for any homeowner wishing to create a dream space in a kitchen, dining room or lounge.

If there is just one slim frame sliding door that represents all that is beautiful and technically brilliant about modern glazing, it is the Reynaers MasterPatio aluminium sliding door. This is, without doubt, one of the best performing and most sought-after doors on the market, and for good reason. If you’re involved in high-end refurbishment of your property, or you’re an architect or installer looking to impress clients, this sliding door with its strong aluminium frame is The One.

Thermal superiority

There are many reasons for choosing the MasterPatio door, as we will see, but one of the most compelling ones must be its outstanding thermal performance and all-round sustainability.

The MasterPatio very much ticks the sustainability box, as it uses recycled profiles and insulation bars in its construction. This, combined with reduced water production processes, equates to the reduction of CO2 emissions by a further 1130 tonnes per year, and all without compromising one millimetre on stylish elegance.

In terms of thermal performance, the MasterPatio has been superbly engineering to achieve the best rating, again without compromising style. It more than meets current UK energy efficiency regulations and, given that its U-value is an outstanding 0.82 W/m²K, it also meets stringent Passivhaus standards.

In less technical terms, this means that the MasterPatio door keeps the worst of the UK’s winter weather out, and all the heat in. The highly insulated aluminium profiles are particularly suited to property projects on high ground or in coastal location. During the summer months the door’s thermal efficiency and qualities will keep rooms cool while protecting furniture against the ravages of UV rays.

Sizes and sightlines

The MasterPatio doors can achieve industry-leading sizes, giving full extent to your room and immediately offering the perception of much more space and light. The doors can reach to a maximum element height of 3.7m, allowing for completely unobstructed views to the outside.

The door also features a cutting-edge lift and slide operation which delivers a much lighter open/close mechanism and added functionality. Lift and slide doors can be partially opened to their designed position and then set down and secured, allowing the doors to open slightly for ventilation while only being operable from inside the room. The doors also feature patented glass supports, which ensure a perfect transfer of the glass weight to the wheels, resulting in comfortable operation.

Patio doors of all sizes need to have a convincing amount of security and the MasterPatio certainly doesn’t fail in this field. While most of the door’s components are concealed or flush to the unit, this doesn’t mean that security is compromised. The sliding door has a multi point locking system and is PAS 24 security accredited, a standard that can only be achieved once a product has undergone thorough testing and has been assessed for high security performance levels. 

Stylish finishes

The MasterPatio system is available in more than 450 colour options and finish types, complementing every type of existing environment and personal taste. Finishes include metallic or anodised, matt or gloss RAL colours, wood look aluminium or even a special low-maintenance and scratch-resistant coatex finish.

The MasterPatio has certainly caused waves among our many customers, and as we battle through winter while looking forward to next summer, we’re sure that many more householders will come to enjoy the benefits of this unique sliding door system. But don’t just take our word for it – the outstanding design qualities of the MasterPatio system stood out in the prestigious Red Dot Awards 2021, in which the system was highly praised in Design Elements category. The jury report says: “The design of the MasterPatio sliding door system succeeds in combining state-of-the-art sustainability requirements with excellent insulation performance and a clear design idiom.
