New Part L

What is Part L?

Part L is a section of the Building Regulations which standards set the levels of thermal insulation required when carrying out building work. These are expressed as a U-value which needs to be achieved. The required U-value will depend on the location of the project (England, Scotland or Wales), type of building (domestic or non-domestic) and the application (floor, wall or roof). Essentially the Building regulations in England set the standards for the energy performance of new and existing buildings.

What are the changes to Part L?

The headline is, all new homes will have to produce around 30% less carbon emissions than the current Part L document, which is part of a major update to Building Regulations. These new regulations are to be introduced for all planning applications from 15th June 2022.

  • 30% cut on emissions from new homes, as well as a 27% cut on new buildings including offices and shops.
  • New homes will adopt the Fabric Energy Efficiency Standard to measure energy efficiency.
  • There will be a maximum flow temperature requirement of 55°C for new and replacement heating systems, as part of the Part L uplift.
  • An appendix has been included in Part L which sets out a good practice specification for a home built with a heat pump.

Why is the update required?

The significant update provides an uplift to existing energy efficiency standards for homes and marks a steppingstone towards the introduction of the Future Homes Standard in 2025.

The Future Homes Standard has been set out by the Government in order to reduce household carbon emissions by at least 75% in comparison with existing levels. Homes built to the standard will need to be “net-zero carbon ready”. This means they will require no additional energy retrofit work to reach net-zero carbon emissions once the national grid is decarbonised.

How can Glosford help with this?

To achieve this, all new homes will need to have outstanding fabric performance, with potential thermal bridges carefully addressed, and to be heated by low carbon technologies such as air or ground source heat-pumps.

Glosford provide superstructures constructed from Structurally Insulated Panels (SIP’s) which have a unique
combination of low U/values, minimal cold bridging and superior airtightness.

We provide a simple yet effective solution to exceed the airtightness figures set out in the new regulations. It is not uncommon to achieve between 1 and 2 air changes per hour, whereas the new regulations are set at 5. The low air
permeability also increases the efficiency of low carbon heating technologies such as mechanical ventilation & heat
recovery (MVHR) and heat pump solutions.

The continuity of insulation, 96% of the wall and 99% of the roof, greatly reduces the risk of cold bridging and thermal loss in a structure.

In addition, Glosford’s attention to detail during design, CNC manufacture and whilst erecting your superstructure are truly market leading. This sets us apart from other methods of construction and other SIP suppliers. Please don’t take our word for it, have a look at the testimonial page on our website available here.

All of the above makes Glosford the ideal partner for your build.

Welcome to the Glosford Team!

We are delighted to welcome 4 new employees to the Glosford team.

‘I started working for Glosford SIPS on the 17th of January 2022 as an accounts & administration assistant.

I had over four years’ experience of working in finance when I joined the team here at Glosfords and I can’t fault how welcoming everyone is! 

My other occupation is cake making during evenings and weekends so it’s the best of both worlds with the occasional office cake too!’

Glosford SIPS Win Best SIPS Home at the Build It Awards 2021!

We’re extremely pleased to have won Best SIPS Home at the Build It Awards 2021!

For 10 years the Build It Awards have been the most coveted accolade in the self build industry.

The project was a unique self build detached 2 storey private residential dwelling situated in a 20 Acre Field in Rural Worcestershire. This was a difficult site to gain planning permission on as it is situated in open countryside. Consequently an exceptional high quality of design was required to unlock the site. The Architect having secured permission for an ambitious design inspired by the hop growing industry of the region the clients then needed to be able to deliver it. In essence the design consists of 3 no. hop kilns set at different levels and angles to each other and ranging in height from 11.7 to 13.1m In addition to realising the ambitious concept the design needed to meet a number of other criteria

1. High levels of insulation and airtightness in excess of current Building regulations requirements to ensure building had high sustainability credentials.

2. Sourced from renewable materials.

3. Procured locally

4. The homeowners were to live in the caravan throughout the duration of the build so as short as possible construction period was required.

5. The site is very exposed (on top of a hill in open countryside with 360 degree views and weather) The Architects were concerned as to the stability and safety of the building during the construction process as the site can get very windy. Their thoughts quickly turned to timber to answer points 1-3 and then to prefabricated timber in order to deal with points 4&5. SIPs seemed to offer the perfect fit for this particular project in this particular location and so it proved to be. The Clients chose Glosford and found our quotation competitive and within budget. Work was commissioned and many meetings with Glosford and the Architect then followed to enable the final construction drawings to be completed. Glosford’s scope included the 172mm Kingspan TEK SIP wall and roof system along with all internal partitions and floors together with all the structural steel framing required.
