How To Glaze A Window Using Beading
In its basic form, double glazing is ii pieces of glass hermetically sealed with a cavity in between. The main benefits are improved estrus and sound insulation. Cavity sizes vary, but you lot're most probable to meet a gap of betwixt 12mm to 20mm sandwiched betwixt ii sheets of glass either 4mm or 6mm thick. If you lot have a big plenty rebate in your window frame, larger gaps betwixt offering greater insulation, but get wider than 300mm and convection currents increase heat loss.
Over the years, in that location have been some significant leaps in technology for both the glass used in double glazed units and the gas that goes between information technology. And equally units occasionally fail, it's a adept chance to upgrade your window's performance. Even better, yous can practice information technology on a DIY basis.
- Tape measure
- Hammer
- Nail punch
- Scraper
- Double glazed unit
- Non-hardening butyl putty
- Roll(s) of high-security glazing tape
- Spacing blocks
- Beading tacks
one. Starting time past working out the size of the glass you need. Measure frame edge to frame edge. Make certain you also know the thickness of the unit. The 20mm size (too known as 4-12-4, meaning two panes of 4mm glass with a 12mm gap in between) is mutual in domestic windows. Simply to cheque what thickness unit of measurement you accept in your frames, remove one piece of beading (see steps iii and 4) and slide a ruler into the rebate to measure the overall thickness of the glass.
two. If you are replacing several panes then a rough sketch of the window with the various measurements side by side to information technology means none will become left off the order. When ordering, tell the glass merchant that the measurements are 'tight' to the frame. The merchant will then deduct a small amount off each dimension (normally 5mm) for clearance.
3. The beading that holds the glass in on plastic window frames snaps into a recess and can be removed with careful prising and and then reused. If you accept wooden window frames (as here), the beading can also exist reused but you'll need to knock the nails that secure it to the frame through with a smash dial. Some windows have the removable beading on the exterior (equally here) and are said to be externally glazed. Others have the beading on the inside and are known every bit internally glazed windows.
four. Pull beading abroad. If possible, get out the top section of beading until concluding and then back up the glass as you remove information technology. Glass units fitted in wooden windows are normally sealed in with some form of putty-based fixing compound. This will need to be cut away before the glass can exist removed.
5. Lay out the beading in the shape of the window so information technology tin be refitted easily afterwards on.
half dozen. On wooden frames, remove all traces of excess fixing compound with a scraper and and so thoroughly clean out the window rebate with a soft castor.
7. Trial fit the replacement double glazed unit in the window aperture. If information technology doesn't fit, don't attempt and force it. Pull the glass out and check for any obstructions before trying again. Don't move on to the next stage until the unit slides into the frame easily.
8. In one case you're happy with the fit of the unit it's time to record it up. Windows in plastic frames are sandwiched betwixt a pair of gaskets. For added security on externally glazed frames it'due south a good idea to replace the internal gasket with a high-security glazing tape. This double-sided PVC foam tape sticks to the frame and glass and makes it about impossible for the window to be removed without breaking it. If you're plumbing equipment drinking glass to a wooden frame, apply strips of flexible non-setting butyl putty (we're using Flexistrip hither) to both sides of the glass. Y'all tin also apply high-security glazing tape as above for externally glazed wooden frames.
nine. Fit and centralise the glass in the frame. Special units (as mentioned in the introduction) will be labelled up to show which side should face outwards. If the unit of measurement is going into a fixed window, fit spacers as shown in the diagram. Glass in opening windows needs to exist stopped from moving in the frame and so spacers need to be placed as shown for side- and tiptop-hung openings. For side-hung openings with the hinge on the opposite side, the position of the spacers needs to exist reversed. Try opening and endmost the window (holding the glass in place, of class) to make certain it works smoothly. If the window doesn't operate easily, slight aligning of the spacer blocks will unremarkably become it sorted.
10. Finally, press plastic beading or nail wooden beading back into place and the job is complete. Next window, please…
