Explore Line DetailsNavigating Finland's rigorous National Building Code (Rakentamismääräyskokoelma) and ambitious net-zero targets through state-of-the-art Extruded Polystyrene (XPS) manufacturing.
Finland presents one of the most demanding environmental landscapes in Europe for building envelopes and civil infrastructure. With winter temperatures routinely dropping below $-30^\circ\text{C}$ in Northern Lapland and sub-zero freeze-thaw cycles spanning over six months annually in southern coastal cities like Helsinki, Turku, and Tampere, standard expanded thermal insulations fail to maintain long-term structural integrity.
Extruded Polystyrene (XPS) boards produced via Amulite’s high-pressure twin-screw machinery deliver a closed-cell structural matrix exceeding 98% closed-cell ratio. This micro-cellular structure guarantees near-zero water absorption ($\le 0.7\%$ long-term immersion per EN 12087), preventing freeze-thaw spalling, internal ice crystallization, and thermal degradation across decades of operation.
The European Union's aggressive phase-down of hydrofluorocarbons (HFCs) under Regulation (EU) 2024/573 has forced insulation manufacturers across Finland to dismantle conventional R134a and R152a foaming systems. Non-compliance risks severe administrative fines and market exclusion under the Nordic Swan Ecolabel (Joutsenmerkki) standards.
Amulite’s XPS Foam Board Production Line utilizes an advanced dual-stage tandem extrusion architecture designed for Supercritical Carbon Dioxide ($sCO_2$) combined with Ethanol/LPG as eco-friendly blowing agents. This system achieves a Zero Ozone Depletion Potential (ODP = 0) and a Global Warming Potential approaching unity (GWP ≤ 1), empowering Finnish manufacturers to deliver 100% compliant, eco-certified insulation boards without sacrificing cell uniformity or density consistency.
In Finnish civil engineering, sub-grade ground frost protection (*routaeristys*) requires insulation boards to endure static and dynamic structural loads from ground heave, heavy transport, and moisture saturation. Amulite’s twin-screw primary compounding line allows precise micro-dosing of nucleating agents, achieving compressive stress ratings from 300 kPa up to 700 kPa at 10% deformation (EN 826 certified), meeting the strict Finnish Transport Infrastructure Agency (Väylävirasto) specification requirements.

Features multi-component gravimetric loss-in-weight feeders for general-purpose polystyrene (GPPS), recycled PS scrap, flame retardants (HBCD-free / polymeric FR), and color masterbatch. High L/D ratio co-rotating twin-screw primary extruder ensures homogeneous polymer plasticization.
Custom gas metering station injects liquid $CO_2$ at ultra-high pressure (>25 MPa) into the melt barrel. Precise mass flow meters control gas concentration down to 0.1% accuracy, ensuring consistent expansion ratios without cell collapse.
Secondary single-screw cooling extruder lowers melt temperature to optimal foaming point. Flat slot die feeds vacuum calibrator plates to fix board thickness (20mm to 120mm) and form tongue-and-groove or lap-joint edges.

How XPS boards produced by Amulite equipment solve real-world structural challenges across Northern European climates.
Foundation slabs, shallow footings, underground utility ducts, and rail beds across Finland require heavy insulation to prevent frost from penetrating frost-susceptible soils. Amulite lines feature inline surface embossing and high-density calibration units that produce high compressive XPS boards (350-700 kPa) capable of sustaining dead loads from heavy structures without long-term creep strain.
In modern Finnish urban design, inverted flat roof construction places thermal insulation above the waterproof membrane. This exposes boards to constant precipitation, freezing slush, and direct mechanical wear. Amulite-produced XPS boards maintain water absorption figures below 0.7% under 28 days of total immersion (EN 12087), preserving thermal resistance year-round.
With Finland serving as a critical Scandinavian logistics corridor, demand for deep-freeze storage (-30°C) facilities is rapidly expanding. Amulite lines produce tongue-and-groove interlock boards up to 120mm thickness, eliminating thermal bridging in refrigerated warehouse floor slabs and wall envelope structures.
Finland leads Europe in off-site timber element construction (*puuelementtirakentaminen*). Our lines integrate precise edge milling machinery (lap-joint, ship-lap, smooth beveling) for continuous slot-in installation within industrial wood framing systems and precast concrete sandwich panels.
Amulite provides complete regulatory support, equipment certification, and localized engineering assistance to guarantee rapid plant commissioning.

How Amulite’s R&D roadmap aligns with Finland’s transition toward fully circular construction materials and AI-driven smart factories.
Inline edge trimmers, defective board crushers, and heavy-duty pelletizing systems allow factory scrap to be re-ground and re-fed into the primary extruder at rates up to 100% without degrading mechanical cell performance.
Our barrel heating zones and screw profiles are modified to handle bio-attributed GPPS derived from forestry side-streams (tall oil derivatives native to Finland’s timber paper industry), enabling true bio-circular XPS insulation boards.
Laser thickness gauges and dynamic ultrasonic density scanners continuously monitor the foamed sheet post-calibration. Real-time feedback automatically adjusts $CO_2$ gas injection pressure and screw RPM to eliminate human error and lower resin waste.
