Construction types

Inner leaf types:

- Traditional blockwork
- Timber-frame
- SIPs
- Steel Frame (SFS)
- Insulated concrete former
- BBA certificate here

Traditional blockwork

Building an internal block wall has for years been the main construction method for the inner leaf. By using SureCav and removing the need for a concrete block backing wall when building with stone or flint, the standard wall make-up would be:
100mm or wider internal block
50mm or more insulation
SureCav25 or SureCav50
Ventilated residual cavity
Outer leaf of stone or flint

Method:
Install the wall ties every 450mm vertically, as usual. To prevent slots having to be made in the SureCav sheet on each course of block-work when building away from a doorway or window reveal additonal wall ties at 450mm vertical centres within 225mm of all openings are recommended. This method will satisfy structural requirements. The SureCav panels simply slot between the ties, in the same way as the insulation batts, and are held in place with the wall tie clips. Build one or two rows of SureCav ahead of the masons.

To prevent having to pierce the panels, the wall ties are fixed each
450mm board course to coincide with the horizontal SureCav joints. Cut
the joining strips to meet the wall-tie and then continue the other side
with the off-cut. Download technical drawings

Timber-frame

Timber-frame construction are very popular because of their rapid build times and excellent thermal performance. The typical wall make-up would be:
Timber-frame (usually 100mm - 140mm wide c/w insulation between the studs)
Vapour control layer
Sheathing
Breather membrane
Possible addional insulation layer
SureCav25 or SureCav50
Ventilated residual cavity
Outer masonry finish

Method:
The complete SureCav system can be screwed to the timber-frame sheathing before the masons start, using the seal washers supplied by SureCav at the recommended 5 washers per panel. Fixing the Surecav this way will ensure the sheets are firmly fixed, even in high winds. On the top of each row of SureCav, fix the timber-frame ties to the studs at the required centres. Trim the joining strip up to the tie and continue the other side with the offcut. Check with your architect, timber-frame designer or structural engineer about selecting the correct fame tie. Download technical drawings

Structural Insulated Panels

SIPs are engineered panels used to construct walls, ceilings, and floors. As a replacement for construction methods using traditional timber-framing and insulation, SIPs provide an extremely durable, strong, and energy-efficient building option. A typical wall make-up would be:
SIPs panels (usually 140mm - 170mm wide)
Vapour control layer & Breather membrane
Possible addional insulation layer
SureCav25 or SureCav50
Ventilated residual cavity
Outer masonry finish

Method:
SIP panels do not have main support timbers so the tie can be placed in any suitable position along the length of the SureCav panel. Stainless steel wall-ties can be directly attached to the OSB/3 face of the panel using stainless-steel screw fasteners. Ties are placed every 450mm vertically, at the required centres, to coincide with the SureCav joints. Cut the horizontal joining strip to fit up to the tie and then continue the other side of the tie using the off-cut.

Helical ties can be used in any flat area of the sheet, but should NOT pierce through the pods. Helical ties are especially useful when building with random stonework or flint. The photo to the right shows the SureCav25 fixed to the SIPs with an additional 100mm rigid board insulation. Helical ties were used throughout the project, fixed in place as the masons progressed. Download technical drawings

 

Steel Frame Systems

Steel frame buildings are metal structures, consisting of horizontal steel beams and vertical columns, welded together in a rectangular grid to support floors, walls and roofs of buildings. Steel frame structures are used to form the framework which a building is then constructed around. The metal studs will usually have a sheathing fixed, with an insulation in-fill. A typical wall make-up would be:
Steel frame system
Sheathing with breather membrane
Possible additional insulation
Channel fixings for wall ties
SureCav25 or SureCav50
Ventilated residual cavity
Outer masonry finish

Method:
Fix the channel system to the steel frame, then the SureCav panels to the sheathing, using the SureCav seal washers. If the SureCav pod touches the channel, just insert a section of SureCav to adjust the spacing. The channel ties sit on the top of each row of SureCav at the required centres and can be held in place using wall tie clips. Download technical drawings

Insulated concrete former

Insulating concrete formers (ICF) is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with concrete. Isotex blocks are becoming increasingly popular as a method of formwork. A typical wall make-up would be:
Insulated concrete former
SureCav25 or SureCav50
Ventilated residual cavity
Outer masonry finish

Method: 
The Surecav panels are fixed to the face of the former using fixings points or the method designed by the formwork manufacturer. Download technical drawings

The speed of build, easy storage and handling make SureCav an ideal system. We have found this especially to be the case where storage and working space on site is at a premium.
