Installation & Survey
- Check for any apparent defects and deficiencies around the structural opening. If any defects are found, then these should be solved, prior to the new door being installed.
- The presence of any electrical or specialist items such as television aerials and telephone wires in the aperture should be noted. Wherever possible such services should be routed around, and not through, the outer frame of the door. When this is not possible.
- The presence of any curtain tracks in the aperture should be noted. This is particularly important for inward opening doors. These could either cause problems during installation or interfere with the function of the door after installation. Action to prevent any problems should be solved prior to the installation.
- Where bricks are to be removed to install products, the method of any cavity closing should be specified. It is advisable to consult local authority building control to ensure that any local interpretations, for instance with respect to cavity closing, are taken into account.
- Generally, three measurements of width and height should be taken and the squareness of the aperture determined by, for example, taking diagonal measurements (see Figure 1). The smallest measurement of width and of height is used to determine manufacturing sizes.
- Sub-Sills: The need for any sub-sill should be determined. The size of the sub-sill should be such that there is an overhang of at least 25 mm from the face of the building. The surveyor should determine how the sub-sill is to be fitted, taking into account features such as horns, and how any making good is to be carried out.
- Check the reveal: The difference between internal and external reveal sizes should be determined and checks made to ensure that the operation of any opening light will not be impeded by plaster, render or tiles, etc. A door with a check reveal it is a good idea to remove an internal architrave from the door, to see exactly how deep the reverse brick detail really is and to identify how much of the outer frame can be put behind in the width. A hole should be drilled through the head of the existing box frame to ascertain the maximum height the window or doorset can be put behind the brick. Quite often this differs greatly from the width. If the rebate is sufficient, a 12 mm minimum overlap per side should be allowed. A deeper outer frame might be needed to allow opening out lights to adequately clear the masonry.

A. The purpose of perimeter sealants is to repel water and prevent air leakage in the face of differential movement between the aperture and the or door. Suitable sealants exhibit and retain flexibility and adhesion over this period. The movement class for the sealant will depend on the substrate material, the frame material, and the dimensions of the joint between the frame and the opening. Other considerations include:
- Sealants should be tested and classified in accordance with BS EN ISO 11600. Unless an unusual and specific known requirement determines otherwise, they should be of low modulus and high elasticity, with movement capability of at least 20%.
- Sealant Backing: The sealant should be applied against a firm backing so that it is forced against the sides of the joint during application. To avoid failure in service, the sealant should not adhere to the backing because this would restrict the lateral movement of the joint. These recommendations can be achieved through the use of a closed-cell, oversize circular foam strip. For aluminium framed doors, recommended best practice is to have an insulating fill inserted or injected wherever practicable around their full perimeter behind the external seal between the frame and structural opening.
- Trims & Pressings: All trims should be compatible with the material of the frame and should be colour matched where specified. Finishing trims were used externally, should be good exterior quality materials used in accordance with the manufacturer’s instructions.

- Doors should always be opened and closed in accordance with operating instructions. If you have misplaced the operating instructions, please contact us and we’ll be happy to replace them.
- Hinges and locking mechanisms should be lubricated periodically to minimize wear and to ensure smooth operations.
- In carrying out regular maintenance outside, the internal surfaces are frequently neglected. After a period of time, grime can discolour the inside of the frame and it is recommended that these should be cleaned regularly. Due to the marine coating on your door, would recommend a monthly cleaning interval.
- Wash down with clean warm water containing a non-alkaline liquid detergent (in a concentration which can be handled safely with bare hands) using a non-abrasive cloth, sponge or soft bristle brush. This will remove grime, grease, and any excess chalking. All ridges, grooves, joints, and drainage channels where salt or other deposits can collect should be well washed out, thus preventing corrosion sites from occurring!
- Rinse thoroughly with clean water.
- Dry using a soft cloth or leather.
- Where a reduction in gloss is observed, chalking is evident or excessive staining has occurred, then an approved renovating cream may be carefully applied with a nonabrasive cloth.
- Care must be taken not to abrade sharp corners of section or aris of beads too heavily where the paint film is normally thinner, and it should be remembered that this operation should not be carried out too frequently.
- Polish with a soft cloth to restore gloss and colour uniformity.
- For extra protection, a wax polish can be applied once or twice a year again polishing with a soft cloth to restore the glass.
