Abstract

A method of insulating a building having upwardly extending structural columns or stanchions 4 with wall substrates 5 therebetween, comprising selecting at least one and preferably at least two elongate support members 7 (preferably rails or channel members) of such length as to extend between two or more adjacent structural columns and of such strength as to support at least one insulating panel or slab 6 and any coatings to be applied thereto, securing said support members, such as rails or channel members, to said two or more adjacent columns and not to the substrates therebetween, and locating an insulating panel between two adjacent support members and positioning the lower edge of an insulating panel to rest on a support surface of a member, and securing said insulating panel or slab to the support members; and subsequently applying one or more further coatings to the insulating panel or slab as required.

Description

IMPROVED METHOD OF INSULATING BUILDINGS The present invention relates to an improved method of insulating the external walls of buildings and to a building when so insulated.

It is known to insulate the external walls of buildings to secure insulating slabs to the existing wall substrate by mechanical fixings such as rivets or screw and plug arrangements at regular close spacings directly into the wall substrate which may extend between structural supporting columns. Subsequently meshes, adhesives and renders are applied to the insulating panels.

It has been found that there are some metal or concrete framed buildings which have wall substrates which would be considerably damaged and/or which do not have sufficient strength to support the insulating slabs and any mechanical fixings and additional coatings.

It is an object of the present invention to provide a system whereby metal or other framed buildings with insufficiently strong intermediate wall substrates may have insulating panels secured thereto in acceptable manner.

According to the present invention there is provided a method of insulating a building having upwardly extending structural columns or stanchions with wall substrates therebetween, comprising selecting at least one and preferably at least two elongate support members (preferably rails or channel members) of such length as to extend between two or more adjacent structural columns and of such strength as to support at least one insulating panel or slab and any coatings to be applied thereto, securing said support members, such as rails or channel members, to said two or more adjacent columns and not to the substrates therebetween, and locating an insulating panel between two adjacent support members and positioning the lower edge of an insulating panel to rest on a support surface of a member, and securing said insulating panel or slab to the support members; and subsequently applying one or more further coatings to the insulating panel or slab as required.

The elongate support members are preferably rails and channel members and have elongate supporting means which are securable to the structural columns of the building and are of sufficient strength as to support the insulating slabs and any coatings when only secured to said structural columns and are of a nature to receive the securing means for the insulating panels.

Whilst any suitably shaped rail may be used, e.g.

of T-shaped or L-shaped section, the standard rail member will preferably be of U-shaped section preferably with outwardly directed flanges at the free ends of limbs i.e.

somewhat like a top-hat in section, and the securing means, e.g. screw or nail will be inserted through an aperture in the cross-web and then into the column with the flanges abutting the column and walls. Any suitably shaped member preferably presenting a generally horizontal supporting surface or surfaces for the insulating panel may be used.

When the support members are the channel members such will each have an upward or downward facing channel for receiving the edge of an insulation slab.

The rails and channel members will be located extending normally horizontally and will be arranged vertically spaced apart at a distance substantially equivalent to (slightly greater than) the height of the insulating slab to be attached. If two adjacent channel members should ever be involved, the upward facing and downward facing channels of the two channel members will retain a panel when located in the channels but will have sufficient clearance to permit insertion and removal by the panel being raised into the upper downward facing channel. Similarly when a channel member is used with a rail member the spacing will have to be such to permit location of the panel therebetween.

Securement of the insulating slabs to the rails and channel members will preferably be by screws screwed only into the rails or channel members and preferably having large diameter washers or other enlargement means which act to hold the slabs in place.

The invention also covers a building whenever having the elongate supporting members and insulating slabs thereon secured only to structural columns and also extends to the individual supporting members.

Also according to the present invention there is provided an elongate support member preferably of a generally "top-hat" cross section of such length as to extend between at least two structural columns and of such strength as to support at least one insulating panel or slab secured thereto together with any coatings or surfacings applied thereto.

The invention will be described further, by way of example, with reference to the accompanying drawings, in which: Fig. 1 is a perspective view of a corner of a building having insulation panels secured thereto according to the invention; Fig. 2 is a section on the line A-A of Fig. 1; Figs. 3 to 12 are schematic views of various aspects of the components for use in the method of the invention comprising: Fig. 3 is an elevation of a lipped base rail (or channel member) and a standard rail forming elongate support members; Fig. 4 is an elevation of standard rails; Fig. 5 is an elevation of a lipped sill rail and a standard rail; Fig. 6 is an elevation of bottom lipped rail with full system; Fig. 7 is an elevation of cladding rail with full system; Fig. 8 is an elevation and sill lipped rail with full system; Fig. 9 is part front elevation of the full system; and Fig. 10 is a plan at window jamb.

In Fig. 1 a corner of a building 1 is illustrated with a door 2 and a window 3. A plurality of vertical structural columns 4 of steel or concrete form part of the main structure of the building. Wall substrates 5 are located between columns 4 and are of an unsuitable nature to support insulating panels or slabs 6.

A plurality of elongate support members comprising either rail members 7 or channel members 8, 8' are secured by mechanical fixing (such as screws and plugs 9,10 - Figs. 3-5) only to the columns 4. The rails 7 and channel members 8 are such a strength as to be able to support the insulation panels 6 and any coatings thereon when only connected to the columns 4 and various forms of such rails or channel means are illustrated in section in Figs. 3 to 11.

The rails 7 are of U-shaped section or of a top hat the section with the securing screws 9 extending between the side walls 7' and the outwardly extending flanges 7".

The rails 7 are such that self-tapping securing screws 10 with large washers 11 he-ld captive by the screw ends may be secured thereto and into the end faces between side wall portions 7' to hold panels 6 in position.

Channel members 8, 8' are of generally U-shaped section and are fitted normally at the bottom and top regions of a building.

Various arrangements and combinations of members 7 and 8 are possible.

Pre-galvanised cord formed steel rails to BS 5950 part 5 1987) 7 (or channel members 8 are provided and at for example, approximately 460mm centres (max 500mm centres). These horizontal rails 7 are only fixed back to the columns and, therefore, span between column centres. The rail design is such that pre-cut pieces of insulation can be positioned between the rails and held using drive screws with, for example, 80mm diameter nylon washers. The rail profiles will always be the same but the gauge of the metal used will vary depending on the span and other structural requirements. The insulation slabs can be either Polystyrene, Urethane or Phenolic depending on "U" value requirements and cost limitations.

Gaps between the slabs are filled with spray applied Urethane foam to leave a flat outside surface over which is then applied the glassfibre scrim render beads and render finishes as required.

In summary, the system relies upon the acceptance of cladding fixings being made to existing external cladding at regular close centres without restrictions being imposed by the quality of existing cladding construction and materials.

When providing insulated cladding to many types of PRC and steel framed housing constructed in the postwar period, often existing cladding is considered to be of unacceptable material or quality for fixing to.

In the majority of PRC and steel framed housing types, the main structure consists of either precast concrete or steel columns at close centres in the range of 750 to 1220mm. The invention provides a cladding solution which provides a secondary structure fixed to existing columns or stanchions to which cladding can in turn be fixed at close centres and the preferred solution adopted is to provide rails at maximum 500 centres, the maximum insulated cladding span. Generally the rails are horizontal although vertical rails can, however, be used where the primary existing structure dictates such a solution.

The rails and their fixings to primary existing structure can support lateral wind loads only where the fixings to primary existing structure cannot take vertical dead loads due to the particular system detail of construction, or both lateral wind loads and vertical dead loads when existing details permit.

The design of rails and their fixings to primary structure will therefore depend upon knowledge of the details and dimensions of existing structure and cladding.

Rails are normally of two types as illustrated: a lipped angle rail used to commence any lift of insulated cladding, the lip providing lateral restraint to the cladding without cladding fixings, and, standard "tophat" rails with cladding fixings through the "top-hat" to resist lateral wind loads from cladding above and below the rail.

Where existing construction precludes vertical loads being supported on rail fixings, the dead loads can be taken by the bottom lipped rail at each lift, using special fixings or support brackets, or, at the ground floor level by provision of a special support rail fixed to existing ground floor construction, dependent upon existing construction details.

Rails are galvanised cold formed steel sections, the dimensions and thickness being dictated by design to BS.5950, part 5, 1987 to suit particular loading, dimensions and fixing requirements for each project.
