Purenit from German brand Puren gives you an insulating alternative to spray polyurethane foam, which by its nature does not create symmetrical shapes and can look unaesthetic. Thanks to its excellent thermal insulation and other specific properties, you have a construction material that allows for a wide range of applications thanks to its variability. In today's article, we'll look at what Purenit actually is and what are the properties that make it such a popular material.
Purenite is a polyurethane-based rigid foam (PIR) product that you'll most often encounter in the form of lightweight, rough slabs with rounded edges. How light? Its bulk density is in the range of just 550 ±50 kg/m3. It is also very ductile and can be shaped into slabs or blocks of varying thicknesses and sizes, making it suitable for a wide range of applications. Purenite slabs are also very strong and can be easily screwed into and otherwise modified. They can be machined in a similar way to particleboard (woodworking machines) and can therefore be cut, milled and sanded.
A great advantage is also the health safety of this material, so no special protective equipment is needed during its installation and consequently it does not impose any burden on the operation of the building. Purenite is also environmentally friendly. It can also be glued and combined with other materials or laminated with various covering materials.Purenite has a number of specific properties that make it a very popular material mainly in the construction industry, but also in other fields. Its chemical composition makes it resistant to high temperatures - the material does not burn, melt or drip. Even when continuously exposed to moisture, it does not split, swell or crack and you do not have to worry about thermal bridges or mould. Moisture is wicked away and the material remains unchanged. The material is amazingly resistant to harsh external influences.
Among its main advantages are also its very high compressive strength - it can handle loads of up to 7 tonnes. Purenite also has excellent thermal insulation properties - the declared thermal conductivity coefficient is λD =0.08 W.m-1.K-1.
Purenite can be used in the form of purenite boxes, in which case it serves excellently as an insulating layer, for example, for under-door blinds. Moreover, its properties make it perfectly suited for passive houses.
The aesthetic aspect of purenite is also a significant advantage - unlike purenite foam, it does not form awkward shapes and thanks to its easy processing, you can shape purenite into exactly the shape you need at the time.
