Certikin Premium 475g white underlay (2m wide) – per 25m roll

Enhance the longevity and quality of your newly lined pool with our premium liner underlay or foam. Designed to provide an impeccable finish, this essential accessory is suitable for both site-lined and bag-lined pools, ensuring optimal protection and cushioning for your pool’s lining.

Our 8mm foam underlay is meticulously crafted to a width of 1.02m (3′ 4″), perfectly tailored to fit standard wall depths. This high-quality foam offers superior cushioning and protection, particularly in high-impact areas, contributing to a smooth and durable pool shell surface. It is recommended for use on walls to provide an added layer of defense.

When it comes to metal panel walls, we recommend our underlay felt as a suitable alternative to foam. This felt underlay effectively mitigates the risk of condensation buildup behind the liner, allowing moisture to percolate to the pool floor instead of lingering behind the membrane. Choose the industry-standard 300g per m2 felt, available by the m2 for individual installations or in convenient trade rolls of 200m2 (100m x 2m) for multiple projects.

For a more robust solution, opt for our reinforced underlay felt, featuring a heavier duty construction at 375g per m2. This premium-grade felt includes a woven scrim for enhanced rigidity, making it easier to position on the pool shell planes. Ideal for site lining installations, this durable underlay is commonly used by industry experts such as Certikin and is available in full rolls of 50m x 2m.

Introducing our new economy felt, a lighter-weight option at 250g per m2, designed to offer basic protection for smaller or lower-cost pools. This cost-effective solution ensures that even budget-conscious pool owners can benefit from quality underlay materials to safeguard their pool’s lining.

Suitable for site lined and bag lined pools, liner underlay or foam offers slight cushioning and protection to the rear of the lining and contributes a smoothing effect to the pool shell.Our 8mm foam is cut to a 1.02m (3′ 4-) width to suit a standard wall depth and offers extra protection and cushioning in these higher impact areas. Foam is generally used on walls only. It is recommended that on metal panel walls felt is used in place of foam as differentials in temperature can cause condensation built up behind the liner – felt will allow this moisture to percolate to the pool floor as opposed to sit behind the membrane.Underlay felt is suitable for all areas of a pool structure and is available in three grades.
