Regulations for jobs in Harrow
Under Approved Document K, glazing in critical locations (doors, and side panels within 300mm of a door, up to 1500mm above floor level; other glazing below 800mm) must break safely, be robust or in small panes, or be permanently protected. Toughened and laminated safety glass are classified to BS EN 12600. Replacing only the glass in an existing frame is generally treated as a repair rather than notifiable work.

Can I collect instead of having triple glazed units delivered to Harrow?
Collection is not normally offered, because orders are delivered to site or yard. Ask when you order and we will say whether it can be arranged.
Do I need a trade account to order triple glazed units for a job in Harrow?
Yes, trade prices are for account holders. Applying is quick, and you can send your schedule for pricing while the account is set up.
Can I put triple glazing in my existing windows?
Only if the frames have a deep enough rebate and hardware rated for the extra weight. Most older frames do not.
