3.2 The TV4000 ventilator was tested for airpermeability under the test conditions set out inBS 5368 : Part 1 : 1976(1985) and the resultsare given in Table 3. Results for the TV2000ventilator may be estimated by multiplying theresults by a scaling factor of 0.64, which is theproportional difference in perimeter between theventilators.

4 DurabilityThe products will have a life expectancy equivalentto that of the windows into which they are fitted.

Installation

5 General5.1 The installation of ventilators does not presentdifficulty provided the installation instructions arefollowed.

5.2 When fitting ventilators to PVC-U windows it isimportant to determine whether the frame membercontains reinforcement before cutting/machiningventilation slots. If reinforcement is present, care

should be taken to ensure that it is not weakened orexposed to vented air which may cause corrosion.In cases of doubt the window system suppliershould be consulted.

6 Procedure6.1 To fix the Trimvent 4000 range ventilators tothe window frame appropriately sized slots are cutthrough the head or top rail of the sash and thevent and canopy are screw fixed to ensure the slotis fully covered. The screw heads on the ventilatorare concealed using the covers provided. Toimprove water resistance, mastic should be appliedin the groove at the top of the canopy before fixing.

6.2 The Trimvent sleeve, when used, is insertedinto the cut/machined slot.

Technical InvestigationsThe following is a summary of the technicalinvestigations carried out on the Trimvent 4000Range of Window Ventilators and Sleeves.

7 Tests7.1 Tests were carried out in accordance with themethods defined in MOAT No 1 : 1974 todetermine:permeability to airwatertightness.

ventilation slots. If reinforcement is present, careshould be taken to ensure that it is not weakened orexposed to vented air which may cause corrosion.In cases of doubt the window system suppliershould be consulted.

6 Procedure6.1 To fix the Trimvent Select surface mounted rangeof ventilators to the window frame appropriatelysized slots are cut through the head or top rail ofthe sash. The vent and appropriate external grilleor canopy can then be screw fixed or clip fixed asrequired. The recessed vent requires a routed slot toaccommodate the vent body, which is then screwfixed. The push-in grilles are suitable for frames witha head drip feature, in combination with arecessed or surface mounted internal vent (seeFigures 1 and 2).

6.2 The Trimvent sleeve, when used, is insertedinto the cut/machined slot. Moulded lugs on thevent and grille or canopy help to locate them overthe slot.

Technical Investigations

The following is a summary of the technicalinvestigations carried out on the Trimvent Selectrange of window ventilators.

7 TestsTests were carried out in accordance with themethods defined in MOAT No 1 : 1974 todetermine:permeability to airwatertightness.

8 Other investigations8.1 Existing data relating to material specificationand durability were re-examined.

8.2 The fabrication process and assemblyprocedure, including the methods adopted forfactory production control, were examined andfound satisfactory by the BBA.

TRIMVENT MULTIGLAZE RANGE

Product

• THIS DETAIL SHEET RELATES TO THE TRIMVENT MULTIGLAZE RANGEOF WINDOW VENTILATORS.



1 Description1.1 Trimvent Multiglaze (see Figure 1) is fittedabove the glazing between the glass/glazing unitand the window frame. Units are available toaccommodate glass/glazing thicknesses given inTable 1.

1.2 The ventilators are manufactured in aluminiumwith a satin anodised finish or white or brownpolyester coated finish. Plastic end caps are blackor white. The ventilators include an expandedmetal mesh insect screen and external glazinggasket. An internal wedge glazing gasket is alsosupplied.

1.3 Ventilators in other colours are available butare not covered by this Certificate.

Design Data

2 General2.1 The Trimvent Multiglaze range of ventilators,when used in conventionally glazed windows witha straight head member, will provide the requiredtrickle ventilation while maintaining weathertightness.

*Area depends on overall ventilator length.

3 Weathertightness3.1 The inclusion of a trickle ventilator in awindow will affect its air permeability and mayaffect the watertightness, two of the factors thatdetermine the exposure category (as defined inBS 6375 : Part 1 : 1989) assigned to the window.

3.2 A GV626-B ventilator 1008 mm long with a630 mm long slot was tested for air permeabilityunder the test conditions set out in BS 5368 : Part 1 :1976(1994) and the results are given in Table 3.Results for the other ventilators may be estimated bymultiplying the results by a scaling factor, which isthe proportional difference in perimeter betweenthe slots.

Installation

5 GeneralThe installation of ventilators does not present difficultyprovided the installation instructions are followed.

6 ProcedureThe ventilators are supplied cut to length andassembled. A strip mastic, or resilient closed cellfoam strip or sealant, is placed on top of theglazing/glass unit and the ventilator lowered on toit, the wedge gasket is then applied. The assembledunit is then glazed into the window frame in thesame way as for a full-size glass/glazing unit.

Technical InvestigationsThe following is a summary of the technicalinvestigations carried out on the TrimventMultiglaze range of window ventilators.

7 TestsTests were carried out in accordance with themethods defined in MOAT No 1 : 1974 todetermine:permeability to airwatertightness.
