NEW Geocel AIRBLOCK Low Expansion Flexible Foam Seal
Finding solutions to air leakage in buildings is increasingly pressing, a requirement which is now vital due to legislation and mandatory air leakage testing of new homes, extensions and commercial buildings. Sealant and adhesive specialist Geocel has launched a new solution to some of the most common air leakage points. New AIRBLOCK Flexible Foam is the only air leakage foam seal on the market tested to the latest standards and offers a versatile solution to filling voids to improve energy efficiency.Up to 30% of energy can be lost from a building through excessive air leakage. Now legislation and building regs all require improved air tightness to minimize heat loss and reduce energy costs. Part L of the Building Regs in England and Wales, (Part 6 in Scotland and Part F in Northern Ireland) was revised in 2010 to include much more stringent air tightness tests. Now new residences and commercial ceilings, plus extensions and alterations to homes are likely to be required to achieve results less than 5.
Geocel’s new AIRBLOCK Flexible foam helps fill voids and seal the gaps where air leakage most commonly occurs – where building services enter and leave the building (such as electrical cables vents and pipes), gaps around windows and doors, around suspended floors and loft hatches, even through light fixtures. Because it is a high performance polyurethane foam it will fill and seal most construction materials and remains flexible to absorb movement after it has cured. It can be cut, sawn, sanded, painted or plastered over after application.
AIRBLOCK is the only flexible foam seal on the market which is tested in accordance with EN 12114 – Air Permeability of Building Components and Building Elements. In addition, it is Acoustic Rated to EN ISO717-1 (tested to 60DB), Fire Rated to DIN4102-1 and Driving Rain tested to EN1027, making it the ultimate “safety first” foam. Geocel also supply special one metre long applicator guns to allow the foam to get to hard-to-reach places such as behind stud walls and in roof cavities.
