Just Roof Lanterns

Linear Timber Roof Lanterns

The Linear Timber Roof Lantern Collection is crafted with the same attention to detail as the Classic roof lanterns, but with a more minimalist design while retaining the warmth and beauty of hardwood. These Linear roof lanterns have fewer rafters and are ideal for smaller apertures where optimising natural light is paramount (or simply where a sleeker aesthetic is preferred).

Like the Classic range, the slender, painted timber rafters combine traditional flair internally with a low-maintenance exterior via our unique, weather-resistant, aluminium-capping system.

Available in various sizes, from the compact Hoxton to the spacious Haggerston, each lantern is designed to maximise light flow while ensuring excellent thermal efficiency.

Timber or aluminium?

Timber designs are particularly well suited to traditional homes, period properties and orangeries, while aluminium offers slimmer sightlines and a more contemporary appearance. Our ranges include both standard and bespoke sizes, giving you flexibility to choose a design that suits the proportions and requirements of your project.

Glazing and energy efficiency

Glazing has an important part to play in comfort as well as appearance. High-performance double glazing can help reduce heat loss, while solar-control options can limit excessive heat gain and glare in brighter locations. The right specification will depend on the size and orientation of the glazed area and how the room will be used.

Installation and roof preparation

A roof lantern is installed onto a correctly prepared structural kerb or upstand, so accurate dimensions and suitable site preparation are essential. The required detail will vary according to the lantern system and roof construction. We can provide the relevant upstand information for your chosen design, and installation is available on selected projects.

Planning and Building Regulations

Whether planning permission is required will depend on the property and the wider work being carried out. Some extensions may fall within permitted development, while others require formal approval. Building Regulations can also affect glazing and thermal-performance requirements, so the requirements for each project should be checked with the appropriate professionals or Building Control.

Cost and specification

The cost of a roof lantern will depend on its size, material, glazing, colour, opening vents and whether the design is standard or made to measure. We can provide a quotation based on your required dimensions and specification, and help you compare the available options to find the most appropriate solution for your project.
