Question 1

What are the main benefits of choosing aluminium sliding doors?

Accepted Answer

Aluminium sliding doors offer a combination of strength, sleek sightlines and design versatility that allows architects to maximise natural light while maintaining long-term durability. Their structural stability supports large panes of glass without compromising performance.

TECHNAL's TIGAL and CONFORT Smartline systems build on these advantages, offering advanced thermal, acoustic and weather performance tailored to contemporary commercial and residential architecture.

Question 2

What types of TECHNAL aluminium sliding door systems are available for commercial projects?

Accepted Answer

TECHNAL offers a range of aluminium sliding doors designed for commercial and residential projects, including high-performance sliders, lift-and-slide doors and large scale opening solutions for terraces, balconies and facades. Each system is engineered to deliver sleek sightlines, excellent thermal performance and design flexibility.

The product range supports a wide range of project types, from high-end residential developments through to educational buildings, hospitality, offices and mixed-use schemes. Systems are compatible with other TECHNAL facade and window solutions to create a coherent architectural language across the envelope.

Question 3

How do aluminium sliding doors improve natural light and interior comfort?

Accepted Answer

Sleek aluminium frames allow for larger areas of glazing, creating bright, open interiors. CONFORT Smartline foor example, uses a minimalist 38mm interlock to maximise daylight while delivering a clean, contemporary aesthetic.

TIGAL also supports large glazing with its floor-to-ceiling configurations, enhancing daylighting and ensuring strong visual connection to outdoor spaces even in dense urban settings.

Question 4

Are aluminium sliding doors suitable for high-rise or exposed urban projects?

Accepted Answer

Yes. Aluminium's inherent strength and resistance to corrosion make it well suited for tall buildings and challenging climates. TIGAL is specifically engineered for urban and high-rise environments, delivering excellent wind resistance, watertightness, airtightness and acoustic performance.

Question 5

How do TIGAL and CONFORT Smartline differ in performance and application?

Accepted Answer

TIGAL is a hybrid pull-slide door designed for high thermal, acoustic and weather performance making it ideal for noise-sensitive or exposed locations. It's patented water-tightness technology provides window-level sealing with sliding door functionality.

CONFORT Smartline prioritises minimalist aesthetics and smooth operation for wide-span openings, offering excelllent thermal insulation through glass fibre reinforced polyamide strips and PE-insulated cavities.

Question 6

What thermal performance benefits can aluminium sliding doors offer?

Accepted Answer

High-quality aluminium systems include insulated profiles and advanced glazing to reduce heat loss and improve energy efficiency. CONFORT Smartline integrates 50mm polyamide strips and PE-insulated cavities to achieve strong thermal performance without additional inserts.

TIGAL similarly delivers high thermal insulation, supporting passive comfort and reducing operational energy demands in urban or high-traffic environments.

Question 7

Are aluminium sliding doors effective for reducing external noise?

Accepted Answer

Yes - when combined with suitable glazing, aluminium sliding systems can provide excellent acoustic insulation. TIGAL, for example, can reach up to Rw 45 dB with the appropriate glazed specification, making it suitable for city centres or sites near transport corridors.

Question 8

Can aluminium sliding doors be used to create very large openings?

Accepted Answer

Absolutely. Modern aluminium sliding systems support large leaf sizes and wide spans while maintaining stability and ease of operation. CONFORT Smartline enables expansive openings with up to six sliding leaves across multi-rail configurations.

TIGAL supports heights up to 4000mm and leaf weights up to 300kg, enabling dramatic, floor-to-ceiling expressions without compromising performance.

Question 9

How secure are aluminium sliding door systems?

Accepted Answer

Aluminium frames accommodate robust locking mechanisms and security glazing. TIGAL includes a full-perimeter multipoint locking system and is tested to RC2 burglary resistance standards, offering air flow through its micro-ventilation mode.

Question 10

Are TECHNAL sliding doors compatible with low-carbon and sustainable design goals?

Accepted Answer

TECHNAL is part of Hydro, a global leader in low-carbon aluminium. All TECHNAL systems are available in Hydro CIRCAL® 75R as standard, an aluminium alloy with a minimum of 75% recycled post-consumer scrap. This helps to reduce the embodied carbon in the building envelope by 80% when compared with the European average for primary aluminium production.

For projects where net-zero and low embodied carbon is essential, Hydro CIRCAL® 100R is available on request. This 100% recycled post-consumer scrap aluminium alloy has just 0.5kg CO2e per kg of aluminium.

By combining low-carbon aluminium with high-performance glazing, TECHNAL sliding doors can support projecs working toward Passive House standards, net-zero carbon targets, sustainability certifications and circular design principles, without compromising on aesthetics or performance.

Question 11

Are TECHNAL Sliding doors secure and compliant with UK and Irish Standards?

Accepted Answer

TECHNAL sliding door systems are developed to accommodate multi-point locking and robust hardware, providing a high level of security when specified and installed in line with guidance. Glazing options and reinforcement can also be selected to address specific security requirements.

Compliance with particular UK or Irish standards will depend on the chosen system and configuration. For detailed information on security performance and available test evidence, specifiers should refer to official TECHNAL documentation or contact the technical team.

Question 12

Are TECHNAL sliding doors suitable for new build and refurbishment projects?

Accepted Answer

TECHNAL sliding doors are suitable for a wide range of project types, including new build and refurbishment schemes. Their profiles and high-performance characteristics make them well suited to upgrading existing facades, improving natural light and visual connection to the outside.

In refurbishment projects, particular attention should be given to interfaces with existing structures, structural openings and thresholds. TECHNAL's team and fabricator partners can provide advice to ensure a smooth integration.

Question 13

How do aluminium sliding doors contribute to accessible and inclusive design?

Accepted Answer

Low or flush thresholds and smooth operating mechanisms help create easy transitions between indoor and outdoor spaces. Both TIGAL and CONFORT Smartline offer recessed threshold options designed to support accessibility requirements in UK and Irish projects. The smooth sliding action also supports inclusive design for users with reduced mobility.

Question 14

What glazing thicknesses can aluminium sliding doors accommodate?

Accepted Answer

Both TECHNAL sliding systems support substantial glazing depths suited to modern performance requirements. TIGAL accepts glazing up to 52mmm, allowing for high-performance double or triple-glazed units.

CONFORT Smartline supports glazing up to 53mm, enabling enhanced thermal, acoustic and safety perfoormance depending on project needs.

Question 15

How do I choose the right aluminium sliding door system for my project?

Accepted Answer

The decision is based on project priorities:
- TIGAL is best suited for high-rise, urban or noise sensitive developments where airtightness, weather protection and acoustic comfort are essential. 
- CONFORT Smartline is ideal for residential and commercial spaces where slim profiles, wide openings and minimalist contemporary design are the priority.

TECHNAL's team can support architects and developers from early-stage design through to specification and detailing.
