Taking delivery and on-site care

Delivery and storage

Windows and doors should be delivered to site as close to the time for fixing as possible. The longer they are stored on site, the greater the risk of physical damage and problems relating to weather exposure.

Unloading and handling of windows and doors should be carried out in a safe and careful manner, avoiding damage to the frames and breakage of the factory glazing.

We strongly recommend that windows and doors are stored indoors. It is not good practice to store finished joinery outdoors, even if protected. We recommend that windows are stored vertically on edge and must be prevented from falling over. Never store horizontally and never store to an excess height.

Always allow free circulation of air around stored windows and doors. Never allow moisture and condensation to accumulate.

Avoid warping of the frames during storage by evenly distributing the weight of the units on timber battens and prevent soiling the units by covering with heavy plastic sheeting or tarpaulins until used. Light polythene will tear, trap water, or blow away and therefore should not be used.

Units without factory finish that will be held in site storage for long periods prior to fixing must receive at least a base coat of stain or paint before storage.

Airing

During construction, it is necessary to ventilate the building to avoid condensation forming on the inside of the glass units. Further airing may be required until the building has fully dried out, which can often take up to six months after building completion.

Site finishes

Where pebble dashing is to occur, the entire window should be protected by plywood or similar. Visqueen/Plastic sheeting is not adequate.

Surface treatment

All softwood products from Broxwood are vacuum impregnated; this process is only a protection against rot, fungal decay and insect attack and is not a sealer or a surface treatment. Hence it is imperative that all windows and doors be delivered with full factory finish or receives at least one coat of water repellent, pigmented surface treatment prior to installation or prolonged site storage. This is in addition to the standard vacuum treatment. Colourless wood preservatives do not give any ultraviolet protection and should therefore not be used on external surfaces. Exposed surfaces should receive full factory finish or a minimum of two coats of surface treatment on site.

We appreciate that clients may want to determine their own colours and finishes at a late stage in the contract, but it is in the best interest of the product that they are factory finished. A far superior finish can be achieved by the application of finish paint or stain in the manufacturers technically sophisticated paint shops. Care should be taken that neither stain nor paint comes into contact with weather seals.

Site glazing (not warranted)

Broxwood windows and doors are normally supplied factory glazed. Glass breakages do occur, and some clients prefer to supply their own glazing, although this will not give the guaranteed result of factory glazing. The size and specification of the glazing unit will normally be on the silver spacer bar inside the cavity of the glazing unit, except on some specialist units, such as toughened/laminated glazing units.

Ensure the glazing unit is evenly spaced all round the sash/frame. As such the sash and glass act together to maintain perfect alignment. Incorrect packing can lead to the weight of the glass unit being transmitted unevenly into the sash, such that distortion and warping take place.

Make sure that the factory supplied rubber glazing seals are accurately positioned, and that if mastic or other sealant is to be used, ensure they are suitable for use with timber. To ensure maximum security, secure the glazing unit into the sash.

The above glazing notes are for guidance only and to make sure your products perform over a life time, please consult your local glazier or contact your Broxwood dealer.
