PF152HI Procural
Aluminium mullion-transom facade system with enhanced thermal insulation · Procural
PF152HI Procural is a 152 mm deep aluminium mullion-transom facade system with an additional closed thermal chamber (HI) that provides enhanced thermal insulation. The heat transfer coefficient of the assembled facade, Ucw, starts from 0.8 W/(m²·K) — the system is designed for energy-efficient curtain wall facades on office, retail and residential properties where heat loss through the glazing is subject to elevated requirements.
The profile is made from EN AW-6060 T66 aluminium alloy and allows the facade to be built from mullions and transoms with any spacing suited to a specific project. The closed thermal chamber (HI) further reduces heat loss through the facade's load-bearing frame compared with the standard version of the system, while still allowing either classic pressure-plate glazing or structural ESG glazing as an option.
Logi24 designs, manufactures and installs PF152HI Procural facade systems at its own production facility in Riga, with delivery and installation across Latvia and Europe.

The closed thermal chamber lowers Ucw to 0.8 W/(m²·K), noticeably below the standard version of PF152 at the same profile depth.
The system is designed for facades where minimising heat loss and reducing the building's heating and cooling operating costs matter.
Custom profile spacing allows the facade to be built to almost any geometry and area for a specific architectural project.
Tilt-and-turn windows and hinged Procural doors can be built into the facade plane while preserving a unified appearance and the thermal performance.
Qualicoat powder coating protects the profile from corrosion and colour fading under constant exposure to precipitation, salt and UV radiation.

Installation. Logi24 handles the full work cycle — from joint design and structural calculation to final on-site installation. The installation team fits the mullions, transoms and glazing while meeting the requirements for wind load and the water- and airtightness of the joints, preserving the facade's stated thermal performance. Manufacturing and installation times depend on the facade area, the complexity of the geometry and the type of glazing, and are calculated individually by the manager when placing the order.
Delivery. Logi24's production facility and office are located in Riga, Latvia. From here we deliver and install PF152HI Procural facade systems in Riga and across Latvia, and we also arrange delivery for projects elsewhere in Europe. Large-format facade structures are delivered and installed with dedicated logistics and lifting equipment. Timelines and logistics costs are calculated individually depending on the property's location and height.
Warranty. Logi24 provides a 2-year warranty on installation work and 5 years on the completed facade structure. The Procural PF152HI profile carries a manufacturer's warranty of up to 30 years; the exact term is confirmed by the manager when placing the order.
The entire cycle — from design and structural calculation to installation — is handled by one team, with no subcontractors.
Short lead times for approvals and site visits across the whole country.
We deliver and install PF152HI Procural facade systems outside Latvia as well.

What is PF152HI Procural?It is a 152 mm deep aluminium mullion-transom facade system with an additional closed thermal chamber (HI) that provides enhanced thermal insulation. The system is designed for energy-efficient curtain wall facades on private and commercial properties.
-
What is the heat transfer coefficient of the profile and of the assembled facade?The profile's heat transfer coefficient Uf starts from 1.0 W/(m²·K), and the assembled facade's Ucw is from 0.8 W/(m²·K). The exact value depends on the mullion and transom spacing, the type of glazing, and the glazed module area of the specific project.
-
How does PF152HI differ from the PF152 ESG system?PF152HI is built on the same 152 mm profile depth but has an additional closed thermal chamber (HI) that lowers Ucw from 1.1 to 0.8 W/(m²·K). PF152 ESG focuses on the architectural aesthetics of structural glazing with no visible profiles on the outside, while PF152HI primarily addresses maximum facade energy efficiency. Structural ESG glazing is also available as an option on the HI version.
-
Is PF152HI suitable for energy-efficient and certifiable buildings?The system is designed with facade energy efficiency requirements in mind and suits projects where minimising heat loss through curtain wall glazing matters, including buildings with a target energy efficiency rating. Compliance with specific certification criteria (such as BREEAM or LEED) is confirmed individually with the designer and a Logi24 manager.
-
Can operable windows and doors be integrated into a PF152HI facade?Yes, tilt-and-turn and hinged elements based on Procural window and door systems can be integrated into the facade plane, while preserving a unified curtain wall appearance and the enhanced thermal performance.
-
What properties is PF152HI suitable for?The system suits curtain wall glazing for energy-efficient office and shopping centers, entrance areas of commercial buildings, apartment building facades, and properties with elevated requirements for thermal insulation and energy efficiency rating.
-
How much does the PF152HI Procural facade system cost?The cost is calculated per square metre of facade and depends on the mullion and transom spacing, the type of glazing, the integration of operable elements, and the scope of the project. Submit a request with your facade's parameters and we will prepare an individual quote.
-
How long does facade manufacturing and installation take?Manufacturing and installation time depends on the facade area, the complexity of the geometry, the type of glazing, and the current production workload, and is confirmed by the manager when placing the order. Large-format projects typically take longer than standard windows and doors.
-
Does Logi24 install facades?Yes, Logi24 handles the full cycle — joint design, manufacturing and installation with its own team in Riga and across Latvia, as well as delivery and installation across Europe for suitable projects.
-
How do I place an order for the PF152HI Procural facade system?Submit a request on the website or contact a Logi24 manager — a specialist will confirm your facade's parameters, help you choose the glazing type, and prepare an individual quote for cost and manufacturing time.
In short: PF152HI Procural is a 152 mm deep aluminium mullion-transom facade system from manufacturer Procural with an additional closed thermal chamber (HI). The profile's heat transfer coefficient Uf starts from 1.0 W/(m²·K), and the assembled facade's coefficient Ucw is from 0.8 W/(m²·K). In Latvia, facades based on this system are designed, manufactured and installed by Logi24, which is based in Riga.
PF152HI follows the mullion-transom principle at the same 152 mm profile depth as the PF152 ESG system, but adds a closed thermal chamber that lowers Ucw from 1.1 to 0.8 W/(m²·K). This makes the system a suitable choice for projects where facade energy efficiency is the priority, rather than the architectural aesthetics of structural glazing alone.
A load-bearing frame of vertical mullions and horizontal transoms with custom spacing is filled with glazing units or opaque sandwich panels using classic pressure-plate glazing; structural ESG glazing with no visible pressure plates is available as an option. Tilt-and-turn windows and hinged Procural doors can be integrated into the facade plane.
The PF152HI Procural profile is made from EN AW-6060 aluminium alloy in T66 temper. Air permeability, watertightness and wind load class are determined by an individual joint calculation based on the specific building's parameters and regional regulations. The system is used for curtain wall glazing of energy-efficient office and shopping centres, entrance areas of commercial buildings, and apartment building facades.
Logi24 designs, manufactures and installs PF152HI Procural facade systems at its own production facility in Riga, Latvia, and delivers and installs them across Latvia and Europe. Logi24 provides a 2-year warranty on installation work, 5 years on the assembled facade structure, and up to 30 years on the PF152HI Procural profile under the manufacturer's warranty.
