What is Dryseal?
Fast becoming the specification choice of a growing number of Housing Associations, Dryseal is the unique component based fibreglass or glass reinforced polyester (GRP) roofing system. It comes with a 20 year insurance backed guarantee on materials and labour. Unlike ‘wet lay’ systems, the Dryseal system is supplied pre-cured and ready to install. All Dryseal GRP trims and membrane are manufactured under BS EN ISO 9001 and 14001 quality and environmental controls and are ready for installation on site. As a result of the changes in Irish Building Regulations in early 2014, the system has increased in popularity for domestic and commercial installations all over Ireland.
Dryseal is a waterproofing membrane system made from Glass Reinforced Polyester, which is commonly referred to as GRP or fibreglass. It is different from ‘wet lay’ systems in that the whole system is made up from preformed components packed ready to mechanically fix and joint on site. Manufactured from long-established glass reinforced polyester (GRP), Dryseal can be installed over existing roof coverings, provided that the deck is in good condition. The system is also guaranteed to remain leak free for 20 years and comes with an insurance backed warranty. Dryseal is manufactured under factory conditions in accordance with ISO 9001 Quality and ISO 14001 Environmental standards.
Dryseal is manufactured in the UK in accordance with strict BS EN ISO 9001-2008 Quality Control procedures. British Board of Agrément (BBA) product performance and compliance standards are applied to Dryseal. With Dryseal, you can proceed in confidence that your system is installed with a long-term insured guarantee through a network of Approved Contractors.
Speed of Installation
The means of fixing and jointing make Dryseal quicker to install than 'wet lay' systems but more robust than 'single ply' PVC membranes, because of its high impact resistance. Unlike ‘wet lay’ systems, the only liquid resin used during installation of Dryseal is to seal the joints between the various component parts. This significantly reduces the risk of protracted delays caused by weather conditions or defects in the final product.
Dryseal is a versatile, flexible system which can be used with ease on projects in 'cold' or 'warm' roof configurations from a Leisure Centre through to a domestic extension. It is proven to deliver 20 year guaranteed BBA certified dependability, with an expected life in excess of 30 years. The system is supplied as a package of pre-cured parts that are factory-manufactured under BS EN ISO 9001 and 14001 quality and environmental standards and are installed by a trained and approved contractor from Nationwide Fibreglass.
Dryseal can be easily used in a re-roofing scenario. The existing roof deck can be used, as long as it is in good condition, and with the addition of insulation to form a 'warm' roof. The cost benefits become rapidly obvious: 1. Reduces land-fill costs if the existing roof covering is overlaid. 2. Reduces labour costs. 3. Reduces risk during installation due to shorter 'open' times. 4. Reduces long-term risk as Dryseal is guaranteed against leaks for 20 years. 5. Lower embodied CO2 than any comparable roofing system.
Dryseal can be used for a wide range of commercial installations, such as a private hospital in Sligo, Ireland, where the original failed asphalt roof was overlaid with 100mm insulation and Dryseal. The improvements have resulted in huge savings to heating costs. The system is particularly popular within the commercial sector thanks to its 20-year materials and installation guarantee.
Dryseal's ease of detailing, robust resistance to damage, extensive colour choice and aesthetics have led to repeated use by major clients across the UK and Ireland. Dryseal has been successfully installed for over 20 years and continues to be the first choice for many specifiers.
Dryseal is mechanically fixed and accommodates thermal expansion and contraction forces within the system itself, unlike 'wet lay' GRP systems. As a result of this, there is no need for expansion joints within the membrane, except where a construction joint or localised building movement is present.
Choice of Colours
The colour of Dryseal's polyester top coat can be tailored to suit client requirements and mixed to any BS or RAL colour.
