Installation

The protection layer against ultraviolet radiation, wind uplift and buoyancy, usually consists of gravel with a corn diameter of 15-30 mm (5/8"-1 "), in order to achieve a sufficient degree protection against ultraviolet radiation, the gravel layer should have a Instead of gravel, paving slaps with a minimum thickness of 40 mm (1") can be installed when using 50 mm (2") thick X FOAM SL boards. For each 10 mm (3/8") increase in X FOAM SL thickness the paving slab thickness should be increased by 5 mm (3/16").
The wind uplift resistance of upside-down roofs is considered equal to loose-applied conventional flat-roof construction with similar surface protection.
In particularly exposed areas, paving slabs should be applied instead of gravel, either along the perimeter of the roof (min 2 m wide or over the entire surface).

Externally insulated solid walls

Solid masonry walls may be insulated on their external surface and the insulation covered by an external finish such as render, boarding or tiling. That construction offers numerous benefits: all the thermal mass of the wall lies within the insulation envelope, resulting in a structure with a slow thermal response which is well suited to continuously heated buildings. Solid walls do not require vented cavities to drain away moisture, which eliminates one route for air infiltration, making it easier to construct buildings with low rates of air permeability detail-
ing of windows and doors is easier as there is only one structur-
al plane to consider within the wall large format blocks and thin
 joint systems speed construction and reduce the effect
of thermal bridging.

Timber or steel framed walls

In framed wall construction of timber or steel the insulation is fitted between the studs, combining the structure and thermal insulation into the same plane. The internal face of the wall is lined with plasterboard, whilst the external face can be finished with a single leaf of brick tile hanging, boarding or render system. Where necessary the thermal performance of the wall can be improved by installing a further layer of insulation across the face of the studs: that will also reduce the effects of thermal bridging. The use of framed wall construction has become increasingly common, most notably in the Republic of Ireland and Scotland where the required
U-values for walls are already as low as 0.27W/m2K respectively.

Internally insulated walls

Walls may be insulated on their internal face, with the insulation applied between the structure and the internal finish. Installing the insulation in that way will mean the thermal mass of the wall is outside the insulation, resulting in a rapid thermal response, suitable for buildings which are intermittently heated. Internally insulating walls is a useful solution for upgrading the thermal performance of walls in the course of projects which require consequential improvements. It will not affect the external appearance of the building
