Material specifications of Ekodomes and quality standards
The Ekodome® kits are produced using aluminum profiles that adhere to the EN 755-9 standards. These standards outline the precise measurements and shapes for aluminum and aluminum alloy extruded struts with a cross-section that is no larger than 800 mm. The hubs of our dome frames are constructed using aluminum casting with A360 (US) alloy. A360 is an aluminum alloy known for its exceptional pressure tightness and fluidity. It also contains a high level of silicon, providing excellent corrosion resistance and high strength, even in elevated temperatures. Aluminum is an ideal choice for our dome frames due to its lightweight nature, resistance to corrosion, and the fact that it can be recycled infinitely. These key attributes make aluminum a perfect material for constructing our durable and sustainable dome structures.
For the cover panels, we provide a wide range of options. In our original series domes, we offer opaque panels made from HPL compact laminate. This material offers excellent features, is easy to handle, and comes in a variety of colors and finishes.
High-Pressure Laminate (HPL) panels are created by impregnating Kraft paper with phenolic resins and subjecting it to heat and pressure. These panels have a decorative layer made of a synthetic polymer, which provides a wide range of color and texture options while ensuring strength and durability. They are double-sided with a special coating on the exterior side, making them resistant to UV rays, bacteria, and dirt. With a smooth and non-porous surface, HPL panels are easy to clean and remain clean for a long time. They are also fire retardant, resistant to impacts and mechanical pressure, and do not contain hazardous materials like asbestos or chloride heavy metals. Additionally, HPL panels are highly resistant to corrosion and cracking. They are economical and convenient in terms of technical characteristics and endurance, and can be easily processed, cut, sized, drilled, and formed. Designed to last, HPL panels are highly resistant against humidity, vapor, UV radiation, and acid rain. They come with a warranty period of 10 years.
The transparent panels used in the original series domes are made of polycarbonate, a tough and rigid material known for its strength, durability, and lightweight nature. Polycarbonate is a transparent plastic material that exhibits outstanding strength, stiffness, and impact resistance. It is highly resistant to UV radiation, making it suitable for outdoor applications such as greenhouses, skylights, and nurseries. The solid polycarbonate sheets used in our domes have sufficient thickness to create a durable and practically unbreakable roofing system. They are highly impact resistant and provide better insulation than glass while also being significantly more durable. These qualities make them perfect for emergency shelters. Additionally, the transparent nature of polycarbonate, combined with its UV protection on both faces, makes it an excellent choice for covering skylights and panoramic bay windows in your dwell dome. With proper care, polycarbonate panels can last for about 10 years, which is a fraction of the lifespan of glass.
For our PRO series domes, we offer double-pane glass panels as an alternative to polycarbonate. Double pane glass consists of multiple glass panes, typically 2 or 3, tightly packed together with an air space in between. This design provides excellent insulation properties and helps control temperature in various applications such as sloped glazings, commercial curtain walls, skylights, conference rooms, studios, insulated glass roofs, and indoor or insulated windows. The double-pane glass panels are known for their energy-saving benefits, noise reduction capabilities, and ability to enhance the appearance and resale value of a house.
For the opaque parts of our PRO series domes, we produce our own Insulated Sandwich panels. As mentioned earlier, HPL Compact Laminate is a material we use. Our insulated panels consist of two HPL sheets joined together with a PIR (polyisocyanurate) foam board. This construction ensures excellent insulation properties and helps maintain the desired temperature inside the dome. The HPL sheets provide durability and a wide range of colors and finishes, while the PIR foam board enhances thermal performance. Overall, our Insulated Sandwich panels offer a reliable and energy-efficient solution for the PRO series dome.
The PIR foam used in our Ekodome HPL SIP (Insulated Sandwich Panel) is highly efficient in terms of thermal performance. It is so effective that it only requires half the thickness of other insulation products that are mineral-based. When you choose an Ekodome HPL SIP with a PIR foam core, you can expect R-values ranging from 5-7.2 per inch. R-value is a measure of a material's ability to resist heat flow, and higher R-values indicate greater thermal resistance.
One key characteristic of PIR, similar to PUR, is its ability to act as a barrier against moisture. However, the most significant difference lies in PIR's remarkable flame and smoke resistance. PIR effectively slows down the spread of flames and minimizes the amount of smoke emitted during a fire when compared to products made with PUR.
The hardware and anchor plates used in our domes are the only steel components in our construction. These steel parts play a crucial role in providing strength, stability, and durability to our dome structures. The hardware, including screws, bolts, and fasteners, is carefully selected to ensure a secure and reliable assembly of the dome frame. The anchor plates, on the other hand, are strategically placed to securely anchor the dome to the ground, providing stability and resistance against external forces such as wind and seismic activity. By using steel for these specific components, we ensure that our domes maintain their structural integrity and withstand various environmental conditions.
While the majority of our dome components are made of aluminum and other materials, the inclusion of steel hardware and anchor plates reinforces the overall strength and stability of our domes. We carefully select and design these steel components to meet the highest standards of quality and safety, ensuring that our customers can enjoy their dome structures with peace of mind.
