Conservatory Styles

We install a broad range of conservatories across your local area. These double glazed structures come in a diverse selection of styles, to suit different purposes, architecture and preferences. If you have a more traditional property, you may be interested in either our Victorian or Edwardian conservatory styles. If you live in a smaller sized home, your building could benefit from a lean-to conservatory, which comes with a slanted roof. If you want a grand installation, our gable-end conservatories are the ideal investment. We also offer T-shaped and P-shaped conservatories, which combine elements from other designs to help you create the perfect space within your property. If none of the above designs sounds right for you, we offer bespoke conservatories which are design around your requirements. All our conservatories are made to order. This means that they can designed to your exact tastes, lifestyle needs and architectural requirements. You won’t have to choose from pre selected options that may not be suited to your needs.

uPVC Double Glazed Conservatories

All uPVC conservatories manufactured and installed by Spire Window Systems in Louth come with peace of mind as standard. Enhanced security doors and windows, high quality (audited) components and safety throughout. Conservatories had a negative reputation for being too cold in winter yet hot and
stuffy in the warm summer months. Our conservatories will help regulate the
temperature, so it will feel like any other room in your property.
The double glazing will help the extension retain heat, minimising your reliance
