When winter hits, the swimspalock should insulate effectively and keep your heating costs to a minimum. A thick heavy snow cover should not deform the cover and rainwater should run off. We therefore build our swimspapalock with the utmost care in every detail and for this reason can provide a two-year guarantee.
We believe the best way is to measure your Swimspa, not to measure the old cover. Measure carefully following our instructions and the new swimspa cover will fit perfectly. Keep in mind that an extra centimetre can make the cover a little easier to put on. Detailed instructions on how to measure can be found here.
Insulation blocks 5 to 4 inches thick. Unique to our swimspalock is that these slope from long side to long side and therefore give you the highest thermal insulation comparable to traditional swimspalock.
Construction details |
| Thickness of insulation block highest part The thickness (cut) and high density provide good insulating properties. 5 inches (approx. 127 mm) is a good value, which still keeps the weight of the lid manageable. |
| Thickness of insulation block lowest part Should be slightly lower than the highest point to allow for water drainage. 4 inches (approx. 102 mm). |
| Density of insulation blocks The higher the density the better. 25 kg / m³ is a good value. |
| Reinforcement of the centre section Steel superior to aluminium in strength and torsional rigidity. 2 x galvanised steel U-beam. |
| Placed by reinforcement Avoid recessed reinforcements that can easily damage the vapour barrier. Embedded in the insulation block. |
| Type of vapour barrier Plastic film coated with aluminium. Superior moisture and chemical barrier. Vacuum bagged, hot welded. |
| Insulation in the centre joint Often there are only 2 small cushions at the outer edge of the the centre joint, which means heat loss. |
| Case material Premium marine vinyl |
| Swedish Guarantee 2 years Guarantee according to specification. |

Constructions consists of insulating blocks with a density of 25 kg per cubic metre and is reinforced by a galvanised steel U-beam (steel is superior to aluminium in strength and torsional rigidity) embedded in the insulating block so that it cannot damage the moisture barrier. The moisture barrier is in turn vacuum-sealed, hot-welded and made of aluminium-coated plastic film.
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 fails and the cover takes in water and soon weighs 150 kg. 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. The cost of this material alone represents more than 15% of the total cost of the cover, but it's worth it! Ask our 1000s of satisfied customers over the years!
Marine vinyl which wraps the entire structure is of the highest quality and is anti-UV and anti-mildew treated at the factory. Finally, for maximum durability, the joint of the vinyl is insulated along the entire length of the spalock with 2 small and one long pad to create durability and minimise heat loss.
The quality of the stitching naturally affects the lifespan of the cover. Our spalock is constructed with a double-twisted polyester thread that is basically "tireless". When choosing cheaper designs and materials, there is a risk that handles and stitching will give way over time. Concerns about similar mishaps are unwarranted when purchasing our Sannra™ spalock.
Our YKK manufactured zips on the Sannra™ spa lid are designed for heavy duty products. These heavy-duty zips are resistant to corrosion, rust and resist contact with chemicals from the spa.
