Creating bespoke rooflights using BIM

What’s the most important ingredient for success in any building project? Communication is up there. Delivering the right information at the right time, and in the most appropriate way, is what communication – and genuine collaboration – is all about. It’s what BIM is about too, giving the construction industry the tools and the flexibility… Read more

Is BIM for now or the future?

April 4th 2016 was a milestone in the adoption of BIM in the UK construction industry. Earmarked well in advance by the government’s 2011 Construction Strategy, it was the day on which all centrally procured projects were mandated to use Level 2 BIM. It was a watershed moment when full collaborative 3D BIM, with all… Read more

What makes a rooflight BIM object?

A BIM object, while providing an important visual representation of products and materials for use in design and construction drawings, must offer a lot more than that. Boiled down to the essentials, a BIM object is actually better equated to a spreadsheet in the way that it details the properties of the product in question.… Read more

BIM: The information in the model

Hearing the phrase ‘building information modelling’ conjures mental images of flashy 3D graphics, designed to show off the impressive architecture of some new multi-million pound landmark building. That mental image is almost inevitable – after all, most of our built environment is judged on how it looks, fuelled by media reporting of ‘prizes’ like the… Read more

What type of stairs should be specified for access rooflights?

Designing an access rooflight isn’t just about the glass structure overhead. There’s also the “access” part to think about — how will users approach the rooflight and what are the safety considerations? Unless a rooflight is intended for maintenance purposes, where personnel will only use it on an occasional basis, the access will need to… Read more

Structural floor loadings for walk on glass rooflights

Structural floor loadings for walk on glass rooflights should be stated as Uniform Distributed Load (UDL) and Concentrated Load. Although you should expect a manufacturer or supplier to confirm what loadings the glass is designed to withstand, you should not expect them to provide information on the loadings themselves; this remains the responsibility of the… Read more

What’s the difference between non-fragile and walk on rooflights

Terms such as ‘man safe’, ‘walkable’, ‘walk on’ or ‘non-fragile’ are often used in the construction industry, but these terms should be treated with caution and the specifier should understand the difference when looking to install this type of product. Firstly, all walk on rooflights must be manufactured using glass. GRP or Polycarbonate materials can… Read more

Anti-slip glass for walk on glass rooflights

Glass can become slippery when wet and common sense should be applied when specifying this material for walk on applications such as walk on rooflights. This is of particular importance when the glass is being installed where the public can access it. On a private dwelling it is less likely that the glass will be… Read more

Key specification considerations for box rooflight performance

Glass rooflights provide a fantastic solution for both creating light and space within a building envelope, and converting used space into an extended living area. Due to box rooflights providing access as well as sliding mechanisms, there are a range of factors to consider when specifying for this type of product. 1. Specifying the correct… Read more

Performance of the building envelope – design versus actual performance

For some time, the government has shown concern regarding the gap between theoretical and actual performance within building projects. This potential gap occurs as a result of the following: Builders buying cheaper products than what the architects specify Inaccuracy of data relating to performance Inaccuracy with joints in the building envelope; poor insulation Errors in… Read more
