Sannra™ Swimspalock som passar Hydropool 17FX
Constructions consists of insulating blocks with a density of 25 kg per cubic metre. Reinforcement is via a galvanised steel U-beam.
(steel is superior to aluminium in strength and torsional stiffness) which is embedded in the insulation block so that it does not risk damaging the moisture barrier.
The moisture barrier is in turn vacuum-sealed, hot-welded and made of aluminium-coated plastic film. Thickness and density are extremely important for insulation.
Our Sannra™ Swimspalock therefore has a maximum thickness of 127mm on one long side and 102mm on the other for effective water drainage. For the cover to stay well on the bath, it comes with a skirt (12cm) that prevents the wind from grabbing it. It also comes with buckles to attach to the bath, 2 per short side and 1 per long side per centre section.
The function of the vapour barrier and importance of a spalock is worth commenting on further. One of the most common problems with spalock
is that the vapour barrier gives way and the cover takes in condensation and therefore soon weighs 100 kg. The quality of the vapour barrier is therefore extremely important.
We therefore decided to offer the most reliable vapour barrier on the market and we are convinced that we have now achieved this.
The moisture barrier is made of Mylar, which is a material made of specially treated polyester and aluminium foil.
Marine vinyl which surrounds the entire structure is of the highest quality and is anti-UV and anti-mildew treated at the factory.
