Dessian has 30 years' experience fabricating windows, doors and conservatories. We pride ourselves on manufacturing high quality PVCu products using primarily REHAU profile.


Our Mission Statement

To create a culture where ideas are valued and where every employee believes that they can assist Dessian in delivering a quality product and service that will exceed customer expectations.


Our customers cover the entire range, including Retail Window Companies, Trade Installers, House Builders, Municipal Education & Health Authorities, Fire Authorities, HMP and Housing Associations across Ireland and Great Britain.

Over the years we have achieved a number of accreditations to ensure that all of our products are manufactured to the highest possible level. These include ISO and Kitemark features. We can also supply a range of Secured by Design products, a widely recognised police initiative which promotes the use of security standards on windows and doors to prevent crime on homes and commercial premises.

All of our windows will meet a Window Energy Rating (WER) of either A, B or C depending on build specification. Where specified, a U-Value of 0.8W/m2K can be achieved with triple glazed units.

Dessian can also provide you with the “Satellite” business management tool. This software does more than simply order frames. Satellite will help you to manage your business, professionalise quotations and offer multiple quote options for your customers. It can also create accurate invoices, provide a comprehensive cost analysis of each job and importantly, provide instant glass sizes. Dessian can provide you with full workplace training inclusive of sales, technical and IT support. However, once up and running the system is usually straightforward. Further details are available on request.
