What do commercial & industrial rooflights in Isleworth involve?
Commercial & industrial rooflights in Isleworth means rooflights for warehouses, schools, offices and retail units. We cover the TW7 district and the rest of Greater London, with a survey before any price is fixed.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Think of commercial & industrial rooflights for industrial roofs with tired or fragile rooflight sheets.
Neighbouring towns include Hounslow (1 km) and Richmond (3 km). We offer a survey date when we reply to your enquiry.

Building control and safety duties in Isleworth
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. Product data for building control is supplied with every quote.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.
Read the planning permission guide before you commit to a design.
