Insulation Board Draft Proof Noggin

FOR USE WITH DRYWALL CEILINGS

An essential product to suit the British building trade to fix the "rattling" of insulation boards in loft ceilings.

'Insulation board draft proof noggin' fits restricted void depths by integrating itself with the rigid board insulation. Our noggin / dwang is made out of galvanised aluminum or plastic and is used to hold the insulation and plasterboard in place when it is nailed to a rafter.

Plasterboard / Drywall is a well known product in the building trade used to form a base for plaster on a ceiling or wall.

As is usual practice, makeshift noggins or struts are used to hold the plasterboard in place whilst it is nailed to the rafter. The plasterboard is nailed between the joists or rafters of a roof to form a smooth ceiling.

Recently British Building Regulations have increased the insulation values required of roofs.

An additional air ventilation gap is now required and it is therefore necessary to use a rigid board of a minimum thickness of 65mm.

This presents the problem of fixing noggins (pieces of wood or metal used to hold objects together by means of nails) between joists within the void.

Now that extra thick rigid board is required no room remains between the joist or rafter depth for extra components.

It is therefore necessary to integrate the noggins as shown below. There is provided a means of fixing the plasterboard to the rafters without using a makeshift noggin but by integrating the metal noggin onto the rigid insulation board first, as a form of bridge, bracket or strut.

Our noggin is in the form of a U-section channel and may be fitted to the edge of an insulation board and nailed to a joist or rafter.

Plasterboard is then fitted using drywall screws through the metal / plastic; this ceiling meets the recently altered British Building Regulations insulation requirement. Two noggins are used back to back where boards meet.

1
Insulation is currently cut tightly between joists and relies entirely on the fact it is a tight fit for its security. Some timbers shrink releasing the board and then it is able to rattle in windy conditions.
2
Traditional timber noggin necessitates pushing up the insulation, thereby closing the air gap above.
 3

Traditionally timber noggins have to be inserted in order to carry the 12mm plasterboard over a 600 centre.

4

The metal noggins should come in various thickness' to suit the board specified. One hole either end at 600 centres enables a fix by screw or clout nail.

 5

Simply pushed in and screwed / tacked with a small clout nail.

 6
2 Noggins back to back for 100mm insulation to be slotted in. Noggins may also allow ceiling fixings for pendants, etc
7
Left is 50 x 25 timber noggin and right is the metal noggin securely holding the insulation.
8
Plasterboard is overlaid and fixed with drywall screws to timber joist and one centrally through the metal noggin without the aid of a pilot.
