Due to the ease of application and flexibility of the system, White Knight® can be used as a coating to create an insulated roof system (Warm Roof) or refurbish an existing roof (Cold Roof) when required. This versatile product can be specified in the most demanding of applications where traditional systems would not be suitable. Bespoke recommendations and specifications will be produced by your Regional Technical Manager, who will constantly monitor the progress of the application to issue the long-term guarantee.
For either new build or retrofit applications Garland’s White Knight® seamless polyurethane solution is the perfect choice. By using a combination of cold applied polyurethane products and next generation bituminous membranes we are able to install a fully cold applied warm roof system, which is not only quick and easy to install (which reduces labour costs on installation) but will offer exceptional long-term performance and therefore reducing the life cycle costs.
Garla Therm insulation boards are bonded to the substrate by means of a low-rise single part, fast curing urethane adhesive. Once the insulation boards are fully bonded, a layer of Garla Bond self-adhesive membrane is laid on top ensuring that all laps are sealed, therefore creating a waterproof membrane, ensuring no water ingress to the system. A White Knight® liquid system is applied to the membrane at a thickness dependant upon guarantee requirements.
White Knight® can be used as a coating over an existing roof system, such as mineral surfaced modified bitumen or smooth surfaced mastic asphalt. In some cases the existing membrane does not need to be removed - this would depend upon several factors, the most important being that the underlying insulation is dry and no moisture is trapped in the system. This ‘Cold Roof’ application would attract a standard Garland guarantee from 10 - 25 years. In principal the substrate would be primed followed by the initial base coat layer, the reinforcing fibreglass matting would be laid into the base coat and completely absorbed - after the recommended cure time, the top coat of White Knight® in grey or white would be applied. Normal full cure time is 24 hours depending on weather conditions.
With The Garland Company’s total commitment to providing, innovative products technical design and workmanship to the highest standard it is natural that all systems and applications are backed up by long standing, credible guarantees.
In the knowledge that the correct installation of systems is a critical step in ensuring long term performance, Garland will only recommend contracting companies whose attitudes towards site performance and customer care are in line with the same high principles as their own.
In order to fully understand your project, your Garland Regional Technical Manager will thoroughly inspect your existing roof. Examining the construction and condition of the insitu system as well as identifying any associated construction problems.
