Plinth profiles (also known as starter strips) are the base on which the first layer of insulation is laid. It has an auxiliary function (in levelling Styrofoam boards and levelling gaps), a protective function (made of aluminium, it prevents rodents from getting into the thermal insulation)
and waterproofing (eaves or drip caps allow rainwater to run off freely).
There are two types of profiles available on the market - aluminium i made of PVC plastic. Read how they differ and why PVC ones are becoming increasingly popular and appreciated.

Aluminium and PVC starter strips - what are the differences?

In addition to the material from which they are made, they share a number of important characteristics. First of all construction method - aluminium profiles do not have the integrated glass fibre mesh that plastic profiles are equipped with. In addition, width of slats Aluminium ones need to be matched to the thickness of the thermal insulation layer being used, while those made of PVC only come in one size. Regardless of these differences, the functions of both types of profiles are the same. 

Why PVC plinth profiles?

Until recently, aluminium mouldings were the main choice of contractors and builders. However, they are now increasingly opting for an alternative solution. What is the advantage of using PVC plinth profiles?

• Lower cost - In the total expenditure associated with the thermal insulation of a building or its construction, every saving makes a difference. It is therefore worth remembering that PVC mouldings are cheaper than aluminium ones without losing anything in terms of quality.
• No risk of rusting - in the case of plastic, there is no threat of rust. This increases the strength and resistance of the moulding and minimises the risk of having to replace it.
• Size - The most common size used in new construction in Poland is to fit a 20 cm thick polystyrene slab. Slats are available in 2 m lengths.
• Aesthetics - Once installed, the PVC plinth profiles are invisible and do not affect the appearance of the building shell or add any visual element.
• Ease of installation - The application of the moulding is intuitive and really uncomplicated. Applying the adhesive layer to the fibreglass mesh is not a problem and this process can be further facilitated by using dedicated products.

The installation of the PVC plinth profile can be carried out in a timeframe similar to that of the aluminium installation, but the end result is definitely on a higher level. Once the mesh has been skilfully embedded in the adhesive layer, we create a durable and resistant protection for the lower edge of our thermal insulation material, while at the same time avoiding the risk of cracks and making water drainage more efficient. This eliminates the risk of thermal bridgeswhich occur when aluminium profiles are used, disrupting the effectiveness and thermal efficiency of the building. All the features and advantages of PVC plinth profiles described above largely explain their growing popularity and the desire of contractors to use them.
