Wedge House Update

Today has marked another milestone for the Wedge House scheme. We have finally commenced the installation of the first few aluminium windows into the precast panels up in Thorpe Precast’s factory in Stoke-on-Trent.

Thermal Assessment of a Facade

Why do we need to assess the thermal transmittance in a facade? Why do we need to identify whether there is a risk that condensation might occur? What types of condensation do we need to analyse and how do we quantify it, if it occurs while demonstrating compliance with the regulations? Which regulations do we need to follow? Presently we face these challenges when we start the design of a facade project to provide our clients with the best levels of energy performance on their buildings.

BIM?

BIM?

No one is going to argue at this stage that BIM is anything other than a good idea which should in theory at least make our businesses more efficient and the design and procurement process more effective. From the perspective of a façade contractor, our take on BIM is that it is absolutely NOT about producing 3D images but is all about the INFORMATION with 3D modelling to complement.

Annual End-of-Year Event

Friday 15th December bought with it an excellent, Annual End of Year Staff event, held at the Sea Containers building with a stunning view of the river and the City.

Principles of Acoustics

The subject of acoustics, often perceived as somewhat of a dark art, is something that needs to be considered on almost every project in the façade industry. Whilst this is an extensive and detailed topic we have set out below a few basic principles.

The Lifting Challenge

The challenge – a 1100kg piece of glass, 5.4m wide, 2.1m tall, scaffold just 200mm from the final position of the glass and no tower crane access possible….

Market trends

To find out more about the direction the market is heading, we sat down with Ronnie Myatt (Business Development Manager).

Attracting Millennials to Construction

The problem of an ageing workforce in the UK is a very real one and nowhere more so than within the Construction industry. It has consistently been reported that there is an increasing amount of skilled workers looking towards retirement in the near future, and this paired with a lack of new talent coming through, could equal trouble for organisations who may simply end up without the labour required to operate successfully.

Laminated Architectural Glass

A brief description of the process of manufacturing laminated glass.

Glass suppliers will supply laminated glass in stock Jumbo sizes in various standard configurations of thicknesses and coatings but very often these do not suit the requirements of our project and the glasses must be made up as cut to size laminated sheets.

Heat Treating Glass – craft or science?

Books can and have been written on this topic but hopefully this extremely summarised account will enlighten some.

To increase the strength of float glass we can heat treat it. There are 2 levels of treatment covered under the current standards. Heat Strengthened and Toughened (also known as Fully Tempered). Strengthened glass increases the strength of the glass by 2 and Toughened increases it by 4 to 5 times compared to annealed glass of the same thickness. Of the 2 only Toughened glass is classified as a class A safety glass.

Thermal Fracture in Glass Units

Thermal fracture is the name given to glass breakages that occur due to high ranges of temperature variation within the glass unit. When areas within a glass unit heat up faster and to a higher temperature than other areas within the same unit then it will lead to increased stresses with in a unit and the chance of the glass cracking increases.

When is a defect in glass acceptable?

Traditionally in the UK glass in commercial buildings has been assessed in line with TN 35 published by the CWCT, GGF Guidelines, Hadamar and various BS EN standards. These documents define inspection methodology in terms of viewing distance and angle and crucially what is or isn’t considered to be a defect.

George House – 131 Sloane Street Awarded

We are pleased to announce that the iconic scheme George House (131 Sloane Street) has been awarded the ‘Mixed-Use Development’ award at the UK Property Awards. Due to the combined efforts of the team it ensured it was a great project to be involved in and we are thankful for the opportunity to work along with Cadogan Estates, Stiff & Trevillion, Mace and Trevor Patrick Partnership.

Effect of floor slab movement on system selection

Glazing and cladding systems need to be designed to allow for building movements without compromising the performance or safety of the system. Therefore, the effects of building movements on the glazing system selection needs to be considered at the early planning stage of a project to ensure that the correct glazing system is specified.

Re-accreditation of BSI

Following thorough independent Audits of the Integrated Management System undertaken by BSI, Colorminium have again successfully obtained recertification to all three of the Health & Safety, Environmental and Quality Standards, marking the 6th anniversary of Accreditation to these Standards by BSI.
