Replacement window glass for homes and businesses in Hemel Hempstead
When a double glazed unit sits in a critical location, both panes need to be safety glass, not just the one facing the room. A unit with toughened glass on one side and ordinary float glass on the other does not give safe breakage from both directions.
Older sealed units often have plain float glass on both sides. A replacement unit can use a low-emissivity coated pane and a gas-filled cavity, which reduces heat loss through the glass without changing the frame. The coating faces into the cavity and is not noticeable in normal use.
Safety glass should carry a permanent mark, usually etched in one corner, that stays visible once the glass is fitted. The mark identifies the maker or supplier and the standard it meets, such as BS EN 12150 for toughened glass or a BS EN 12600 impact class.
In England, Approved Document K treats glass in a door or within 300mm of a door edge, up to 1500mm above the floor, and any other glass within 800mm of the floor as critical locations. Replacement glass in these areas should be safety glass, even where the old pane was not.
What's included
- Made-to-measure glass or sealed unit to suit the frame
- Removal of the old pane and cleaning of the rebate
- Removal of old glass and packaging from site
- Survey and measurement of the existing glass or unit

- Coast
- Hemel Hempstead is well inland, around 66 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Hemel Hempstead the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. On south and west elevations, a solar control or low-E coating changes how much heat and glare new glass lets in. North-facing rooms usually benefit more from glass that keeps heat in while admitting as much daylight as possible.
- Access and setting
- In towns and cities, replacing glass in flats or above shops often means planning parking, stair access and lifting large units safely. Laminated glass suits ground-floor windows, acoustic glass helps on busy roads, and conservation areas may need matching patterns.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Replacement Glass in Hemel Hempstead: questions
What guarantee comes with replacement glass?
Manufacturer guarantees apply to new sealed units and glass, and the terms are confirmed in writing. Guarantee terms for the fitting are set out in writing with your quote. Keep the paperwork with your property records, as it identifies the unit and its specification if anything needs to be checked or claimed later.
What is the difference between toughened and laminated replacement glass?
Toughened glass is heat treated so that, if it breaks, it crumbles into small, relatively blunt pieces and leaves the opening empty. Laminated glass has a plastic interlayer between two sheets that holds the pieces together, so the pane stays in the frame. Both count as safety glass when classified to the relevant standard, and laminated also helps with security and noise.
Do I need safety glass in my replacement window?
You do if the glass is in a critical location. In England, that means glass in doors and within 300mm of a door edge, up to 1500mm above floor level, and other glass within 800mm of the floor. Elsewhere in the UK the rules are similar, but the detail differs between nations. The glazier checks each location at the survey.
What affects the cost of replacement glass?
The main factors are the size of the pane, the glass type and thickness, and whether it is a single pane or a sealed unit. Toughened, laminated, acoustic and decorative units cost more than standard float glass. Access also matters, as upper-floor or awkward panes take longer to fit safely.
