A requirement of national building regulations throughout the UK is that the building fabric, and the occupants of the building, are protected from moisture.

The compressive strength of ground floor insulation depends on the type of insulation material selected and the application in which a product is to be used.

Due to the nature of energy efficiency regulations across the UK, it is impossible to state a definitive U-value that any single ground floor construction should achieve.

The loads imposed on a ground floor construction rule out flexible insulation, like mineral wool and stone wool, as suitable products for use in typical build-ups

The ground floor of a building has to achieve a variety of performance requirements, some of which may be more obvious than others.

Dame Judith Hackitt’s review into fire safety and building regulations is driving fundamental change across the whole construction sector.

The difference between testing thermal insulation products by immersion and diffusion is to assess the level of water absorption when the material is sitting/submerged in

Extruded polystyrene (XPS) insulation is unique among common thermal insulation materials for its low moisture absorption and tolerance of wet environments. Whether installed directly in

Standards relating to flat roof and green roof construction distinguish between different types of green roof. These are not the same distinctions we discussed in

A green roof is a flat roof with a planted roof covering, and which can also provide biodiversity in some instances. Like a ‘normal’ flat

ETAG 031 is part of a family of European Technical Approval Guidelines (ETAGs). It was prepared in 2010 under the Construction Products Directive (CPD) –

The design of an inverted warm flat roof – where the thermal insulation is above the waterproofing layer – allows for the possibility of rainwater

Here, we offer guidance on how the compressive strength of ground floor insulation compares to that of other layers in a floor.

At the end of June 2019, the UK Government issued an advice note regarding balconies on residential buildings and fire safety.

A fire usually starts inside a building, so internal fire spread is as critical a part of fire safety regulations as external fire spread. It’s

As one of the two main areas of building design and construction where extruded polystyrene (XPS) insulation is commonly specified, it’s useful to understand how

As one of the two main areas of building design and construction where extruded polystyrene (XPS) insulation is commonly specified, it’s useful to understand how

When considering the fire performance of building elements, generally it is necessary to distinguish between the fire performance of individual components (such as an insulation

A water control layer (WCL), or water flow reducing layer (WFRL), is a loose laid membrane installed over inverted warm roof insulation. The performance of

For a flat roof construction – be it a cold roof, a warm roof, or a warm inverted roof – the calculation method for year-round
