Sunroom Addition & Extension Guide

What is a Sunroom Addition?

A sunroom addition is a prefabricated glass and aluminum structure attached to an existing home, extending the living area without the cost and timeline of a full custom build. Also referred to as a sunroom extension, glass room addition, or patio room addition, these kits are designed to integrate with your home’s roofline and foundation.

WeislandSunroom offers customizable sunroom addition kits in multiple configurations, suitable for both single-story and multi-story installations. Whether you’re adding a sunroom to your house for extra living space, a home office, or a dining area, our prefabricated kits ship globally and can be installed by a local contractor.

Types of Sunroom Additions

Prefab Sunroom Addition

Our most popular option. A complete prefabricated kit manufactured to your specified dimensions, including aluminum frame, glass panels, doors, and all hardware. Ships as a ready-to-install package. Also known as a modular sunroom addition.

Glass Room Addition

A full glass room addition with all-glass walls and roof for maximum natural light. Ideal for transforming a patio, deck, or backyard area into a bright, usable space.

Three-Season vs Four-Season Sunroom Addition

All WeislandSunroom kits feature thermal break aluminum frames and double-glazed glass, designed for use across climate zones; confirm performance for your location with the project team. Optional Low-E coating and argon gas fill are available for enhanced insulation.

Sunroom Addition Cost

Several factors affect the cost of a sunroom addition: size, glass configuration (double-glazed vs. laminated), accessibility, and optional accessories. Contact our sales team with your dimensions for a custom quote. Prefabricated sunroom kits are significantly more cost-effective than custom stick-built construction.
