DIY Double Glazing Systems

Engineering & Design Plastics Ltd stock two very basic and cost effective secondary double glazing systems, EASYFIX and EASYGLAZE. They are both glazed with 2mm thick panels. The majority of our customers use 2mm clear extruded acrylic sheet which is a UV-stable glazing plastic. It is always best to remove double glazing panel in the summer to allow ventilation.

EASYFIX double glazing comprises a flexible PVC edging strip, which is placed neatly around a piece of plastic sheeting, this is then held in position by nylon fixing clips and woodscrews. A mitre gauge to help cut neat accurate corners is available separately, a feature unique to our system. EASYFIX edging strip is sold by the metre (a complete reel holds 30m) for 2mm plastic sheeting, in clear, brown or white. Nylon fixing clips, sold in packets of 12, support the edging strip sizes and are natural or brown in colour. Woodscrews are also sold in packets of 12, while the mitre gauge is sold singly.

An EASYFIX secondary pane can be fixed either to the opening window lights to allow ventilation and use of the windows, or to the main frame for maximum insulation and draught proofing. Where possible, allow the secondary panel to overlap the frame by at least 10mm on each edge.

HELPFUL HINT - The edging strip is always easier to work with and apply when it is warm. We suggest it is put in the airing cupboard or similar place the night before use. When placing edging strip onto the panel DO NOT run finger down the back of the edging strip to apply it quickly, work an inch at a time.

TOOLS REQUIRED

A screwdriver, craft knife or similar, ball-point pen and a tape measure

EASYFIX “mitre Gauge”

USING EASYFIX STEP BY STEP

Place a mark on the edging strip 5cm from a neat squarely cut end.

Lay the edging strip in the channel of the EASYFIX Mitre Gauge so the mark on the edging strip is in the centre of the middle "V". Holding the strip firmly in the two finger grips, cut down each side of the "V" with the sharp knife, being careful not to cut right through the strip.

Now carefully fit the edging strip on the plastic panel, the cut out should mould easily around the first corner. Continue along this edge to the next corner and place a mark with the pen on the edging strip where the panel finishes. This point marks the position of the next corner.

Repeat steps as above  until the edging strip is fitted around the complete panel.

You will need a clip about 5cm from each corner on each side, then clips spaced equally about 20-25cm along the remaining dis­tance.

Position the sheet carefully so there is an equal overlap on the frame on all four sides.

Fix the two clips on the bottom edge 5cm from the corners - these will hold the weight of the sheet.

Make sure the plastic panel is clean and the window perfectly dry before resting the pane on the bottom fixing clips. Fix two clips on the top edge, making sure that one of these first four clips covers the join in the edging strip.

Now complete the window by fixing the rest of the clips as suggested above.

The EASYGLAZE double glazing system comprises two, 2.44M (8’) rigid white PVC sections, a base section and a cover strip. A length of mitre beading is also supplied to assist you in cutting neat, accurate corners. This product is fixed to the frame by self-adhesive tape which is mounted on the base sec­tion. EASYGLAZE is designed to be used with 2mm glazing sheet but should never be glazed with glass. The majority of our customers use 2mm extruded acrylic sheet. The EASYGLAZE system is for internal use only, fixing directly to the frame for maximum insulation and draught proofing. When using EASYGLAZE ensure there is at least 15mm of flat mounting surface around each side of the glass to take the adhesive base section.

HELPFUL HINT - To achieve a neat mitre cut a small piece of mitre bead and insert between the base and cover strip at the point where the mitre is to be cut. Cut the mitre through all sections. This beading has the effect of holding the cover strip at the correct angle so that when applied to the sheet it results in a neat mitre.

TOOLS REQUIRED - A fine toothed saw, mi­tre block and tape measure.

Measuring up for your extruded acrylic glazing sheet

Measure the existing window pane, vertically (measurement A) and horizontally (measurement B). This is the glass only and does not include any frame.

Add 12mm to each measurement A & B. This will give you the size of the sheeting required. Also ensure you have the minimum 15mm mounting surface on each side of your window.

Measuring up for your EASYGLAZE

You will require 2 lengths at measurement 'A' plus 25mm and 2 lengths at measurement 'B' plus 25mm for your window. Add these together to find out how many 2.44m (8ft) lengths you will need.

Using the EASYGLAZE

Ensure cover strip is snapped into base section.

Working with your piece of sheeting, measure the side to which you want to place a strip of EASYGLAZE. Add 13mm to this and squarely cut a length of the EASYGLAZE to suit. Repeat this step for each side.

Insert a small piece of mitre beading between cover and base at the end of the length to be cut. Using the outer corner as a reference point (◄see Diagram), cut a 45° mitre using the fine toothed saw and mitre block. Repeat this step for each corner.

Fit EASYGLAZE to sheeting by removing cover strip, or pressing carefully from one end, until all sides have been completed.

Make sure all paintwork is free from the grease of silicone polishes, as this could affect the adhesion of the tape. Also make sure the window is perfectly dry.

Remove all backing tapes and make sure corners are neat and square. CAREFULLY offer the pane to the window making sure it is correct first time. Press home firmly. (The adhesive is very strong and re-positioning of the pane is virtually impossible)
