was specified for use in conjunction with Pilkington Activ® self cleaning glass for weather sealing the glazed roof and vertical elevations which houses the stunning indoor heated swimming area.
As a focal point of this beautiful holiday home park, the indoor swimming area is required to look pristine at all times, so ease and simplicity in cleaning of the glazed roof and wall elevations is a top priority. For this reason, Pilkington Activ™ was specified; a dual action glass with photocatalytic and hydrophilic properties which break down dirt allowing rainwater to wash away dirt particles. Weatherproofing of the joints in this glass structure equired the selection of a sealant which is compatible with this special glass coating and accommodates the anticipated building movement whilst providing high weather resistance.
Specialist contractor MAG Hansen erected the curtain wall framework and installed the self-cleaning glass panels, which was in itself a complex challenge, requiring the use of a tower crane and specific handling equipment. Following long term trials testing for compatibility, adhesion, flexibility and durability, DOWSIL™ 757 Sealant is specified by Pilkington for use with Activ™ glass and was thus installed on this project for sealing the movement joints in this impressive glazed roof and façade.
DOWSIL™ 757 Weatherproofing Sealant for photocatalytic clean glass is a neutralcure, one-component, Si-hybrid based, low modulus, architectural grade sealant. It has been designed for weathersealing of most photocatalytic and hydrophilic clean glass surfaces where high movement is anticipated and high weather resistance is required to withstand increased temperature and UV radiation. It is ideal for expansion, connection, perimeter and other movement joints.
