Wall, floor, and roof construction methods
Wall Construction Methods
Brick and Blockwork
- Traditional brick and blockwork construction involves building walls by layering bricks or blocks with mortar to bind them together.
 - Often employs a cavity wall construction with two layers separated by an insulated gap, increasing thermal efficiency.
 - Requires skilled bricklayers and can be labour intensive.
 
Timber Frame
- In timber frame construction, the structural framework of the building is built from timber.
 - Walls are made up of timber panels filled with insulation – the panels are clad externally for weather protection.
 - Provides excellent thermal and noise insulation properties.
 - Generally quicker to construct compared to brick and blockwork.
 
Structural Insulated Panels (SIPs)
- Structural insulated panels (SIPs) are pre-fabricated, highly insulating panels used to construct walls, roofs, and floors.
 - Composed of an insulating layer of rigid polyurethane foam sandwiched between two layers of structural board.
 - Quick to install and offers high performance in terms of energy efficiency and structural strength.
 
Floor Construction Methods
Solid Concrete Floors
- Solid concrete floors are constructed by pouring a layer of concrete over hardcore, then adding a damp-proof membrane and thermal insulation.
 - Provides a durable, robust surface suitable for most types of finish.
 - Requires a significant drying period before it can be finished.
 
Beam and Block Floors
- Beam and block floors are constructed using precast concrete beams and blocks.
 - Ideal for ground level installation, offering excellent thermal insulation and damp resistance.
 - Quick to install and doesn’t require significant curing time as with solid concrete floors.
 
Roof Construction Methods
Trussed Rafter
- The most common method of roof construction, trussed rafters are prefabricated structures that provide a quick and efficient method of constructing a roof.
 - Consists of a framework of timber members forming a series of triangles.
 - Ideal for wide spanning roofs and allows for flexibility in room layout beneath.
 
Cut Roof
- Cut roofs are built on site and are cut and fitted to the building structure.
 - Allows for more flexibility and adaptability in terms of design and structure.
 - Can accommodate features such as dormers, chimneys and roof windows.
 
Flat Roof
- Flat roofs are built using timber joists covered with a decking material, then waterproofed with a roofing felt or membrane.
 - Offers the potential for space saving, as it allows for the whole of the interior space to be used.
 - Requires careful design to ensure proper drainage and sealing.
