Box for outdoor blinds - why is purenit the ideal choice?

22.7.2025 Ivan Landa

Outdoor blinds are among the most popular ways of shading single-family and apartment buildings. They not only effectively protect the interior from sunlight, but also have an aesthetic effect and help reduce energy requirements for cooling. However, in order for the system to function perfectly, it is important to pay attention to details that are not visible at first glance - such as the box, i.e. the box into which the blind slats are inserted. This is where purenit comes in, a material that stands out among other solutions due to its properties. So why is purenit the ideal material for boxes for outdoor blinds? You will find out in this article.

What is purenit and what makes it special?

Purenit is a construction material made from hard polyurethane foam, which is pressed into solid boards. The resulting material has high strength, moisture resistance, excellent insulation properties and is extremely stable even under long-term loads. Unlike classic insulation materials (such as polystyrene), purenit does not melt, does not deform at higher temperatures and is not moldy. In the field of construction and the production of window and shading systems, it has become popular in recent years precisely because of its long service life and ability to adapt to various types of buildings.

The greatest advantages of purenit include:

• Low thermal conductivity - excellent thermal insulation
• Dimensional stability - does not change shape even with changes in temperature or humidity
• Resistance to mold and rot
• Easy to work with - it can be milled, drilled or glued
• Does not contain formaldehyde or other harmful substances

Why is purenit ideal for boxes for outdoor blinds?

A box for outdoor blinds must meet several technical and practical requirements. It should be strong, dimensionally stable, well insulated, resistant to humidity and temperature fluctuations, and at the same time allow for easy installation of blinds. Purenit meets all these conditions perfectly:

It has thermal insulation properties

Thanks to its low thermal conductivity (approx. 0.08 W/mK), Purenit helps prevent the formation of thermal bridges in the lining or lintel. This saves heating costs and contributes to the energy efficiency of the building, regardless of whether it is a low-energy house or a passive building.

It is resistant to moisture and rot

The box is often located in the transition zone between the exterior and interior. Moisture, condensation or torrential rain are therefore no exception here. However, Purenit is not absorbent and its structure does not allow mold to grow or the material to degrade. Thanks to this, it retains its properties for many years.

It stands out for its mechanical strength and stability

Purenit is strong and yet relatively light. It can be anchored, milled or combined with other materials. Purenit boxes maintain their shape, even under long-term structural loads or when installing larger blind systems.

The advantage is its easy assembly and processing

As manufacturers and installers, you will certainly appreciate that purenit can be easily modified as needed - pockets, channels or holes can be milled into it. Compared to other building materials, working with purenit is faster, cleaner and more precise.

Purenit in practice

Today, the appearance of a house is no longer just about the color of the facade or the shape of the roof. Hidden elements that create clean lines and details also play an important role. Purenit boxes can be easily incorporated into building openings so that they are not visible at all after the facade is completed, or on the contrary, they form a design element. They are therefore an ideal solution for modern and classic architecture.

Ecological and health benefits

Purenit is a material that is harmless to health. It does not contain volatile organic compounds, formaldehyde or other pollutants. No toxic fumes are produced during its production and use, which makes it a safe choice for family homes, schools, kindergartens or hospitals. In addition, purenit is recyclable, making it environmentally friendly.
